Description

Technical Field

[0001] The present application belongs to the field of automation equipment, and more specifically, relates to a fully automatic step-down fine grinding integrated equipment. Background Art

[0002] A micro drill bit usually refers to a drill bit with a diameter of less than 3.175 mm. As the pace of upgrading of electronic information products continues to accelerate, various new types of PCBs continue to emerge, and micro drill bits are developing in the direction of smaller and smaller sizes. Among the micro drill bits that can be produced at present, the minimum diameter can reach 0.01 mm. The formed micro drill bit is mainly composed of a rod at the bottom and a drill needle at the top.

[0003] To ensure better hole wall quality and reduce friction between the drill bit and the hole wall, the drill bit has evolved from the ordinary ST type, where the outer diameter of the drill bit is consistent from front to back, to the UC type, which is a design with a larger outer diameter at the head and smaller outer diameters in the middle and rear sections. This greatly reduces the contact area between the drill bit and the substrate when drilling holes of the same outer diameter, thereby reducing the frictional heat between the drill bit and the hole wall during the drilling process and improving the hole wall quality.

[0004] Micro drills are made from high-strength alloy rods through a series of processes, including grinding, sharpening, and back grinding. Currently, grinding rods primarily uses a precision grinder. When producing UC-type micro drills, a step-down layer must be machined on the outer wall of the drill tip before sharpening. However, current precision grinders lack this capability, requiring the rod to be machined first and then transferred to a UC slotting machine for machining. This method requires the rod to be clamped on at least two machines, significantly impacting micro drill production efficiency. Summary of the Invention

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0040] like Figure 1 、 2As shown, a fully automatic step-difference fine grinding integrated equipment includes a machine 1 and a controller. The machine 1 is provided with a manipulator loading and unloading mechanism 2 and a rotary conveying mechanism 3 respectively connected to the controller. The manipulator loading and unloading mechanism 2 is connected to the rotary conveying mechanism 3. The manipulator loading and unloading mechanism 2 is used to convey the products to be processed to the rotary conveying mechanism 3 and to take the processed products away from the rotary conveying mechanism 3; a rough grinding mechanism 4, a fine grinding mechanism 5 and a step-difference slotting mechanism 6 are provided on the machine 1 along the movement direction of the rotary conveying mechanism 3. The rough grinding mechanism 4, the fine grinding mechanism 5 and the step-difference slotting mechanism 6 are respectively connected to the controller. The rotary conveying mechanism 3 can transport the products to the rough grinding mechanism 4, the fine grinding mechanism 5 and the step-difference slotting mechanism 6 respectively. The rough grinding mechanism 4 and the fine grinding mechanism 5 are used to grind the bar material, and the step-difference slotting mechanism 6 is used to perform step-difference slotting on the outer wall of the bar material.

[0041] During operation, the user places the rod material to be processed on the manipulator loading and unloading mechanism 2, and controls the operation of each mechanism through the controller. The manipulator loading and unloading mechanism 2 transports the product to be processed to the rotating conveying mechanism 3, and the rotating conveying mechanism 3 transports the product to the rough grinding mechanism 4, the fine grinding mechanism 5 and the step-down slotting mechanism 6 in sequence. Finally, the processed product is transported back to the manipulator loading and unloading mechanism 2 by the rotating conveying mechanism 3, and then unloaded by the manipulator loading and unloading mechanism 2; among them, when the product is transported to the rough grinding mechanism 4 or the fine grinding mechanism 5, both the rough grinding mechanism 4 and the fine grinding mechanism 5 can grind the outer wall of the drill bit and grind the drill bit into a preset diameter. When the product is transported to the step-down slotting mechanism 6, the step-down slotting mechanism 6 will open an annular groove of a preset size on the outer wall of the drill bit, so that a step-down layer is formed on the outer wall of the drill bit.

[0042] The fully automatic step-difference fine-grinding integrated equipment is equipped with a rough grinding mechanism 4, a fine grinding mechanism 5 and a step-difference grooving mechanism 6, so that the grinding of the drill bit and the processing of the step layer on the outer wall of the drill bit can be completed on one device, which not only improves the processing efficiency; at the same time, processing on one device can also ensure the concentricity of the step layer and the drill bit, thereby improving the processing accuracy of the micro drill.

[0043] like Figure 3As shown, the manipulator loading and unloading mechanism 2 includes a loading and unloading base 21 and a rotating module 22. The loading and unloading base 21 is fixedly installed on the machine table 1. An X-axis module 23 and a Y-axis module 24 are installed on the loading and unloading base 21. The X-axis module 23 is arranged above the Y-axis module 24, and the X-axis module 23 and the Y-axis module 24 are respectively connected to the controller; a discharge mechanism 25 is slidably provided on the Y-axis module 24, and the discharge mechanism 25 is used to store products to be processed and processed products, and the Y-axis module 24 can drive the discharge mechanism 25 to move forward and backward; a loading and unloading grabbing mechanism 26 is slidably provided on the X-axis module 23, and the loading and unloading grabbing mechanism 26 is connected to the controller, and the X-axis module 23 can drive the loading and unloading grabbing mechanism 26 to move left and right, and the loading and unloading grabbing mechanism 26 is used to place the processed products on the discharge mechanism 25, or to grab the products to be processed from the discharge mechanism 25.

[0044] The rotating module 22 is respectively connected to the loading and unloading grabbing mechanism 26 and the rotating material transporting mechanism 3. The rotating module 26 is used to transport products back and forth between the rotating material transporting mechanism 3 and the loading and unloading grabbing mechanism 26. The loading and unloading grabbing mechanism 26 can grab the products to be processed from the discharge mechanism 25 to the rotating module 22, and can grab the processed products from the rotating module 22 to the discharge mechanism 25. The rotating module 22 includes a rotating mounting plate 221 and a rotating cylinder 222. The rotating mounting plate 221 is fixedly mounted on the machine 1, and the rotating cylinder 222 is fixedly mounted on the rotating mounting plate 221. The rotating cylinder 222 is connected to the controller. A rotating rocker arm 223 is installed on the output end of the rotating cylinder 222. The middle part of the rotating rocker arm 223 is connected to the rotating cylinder 222, and product clamps 224 are respectively provided at both ends of the rotating rocker arm 223; the driving stroke of the rotating cylinder 222 is 180°, that is, every time the rotating cylinder 222 works once, it drives the rotating rocker arm 223 to rotate 180°. During operation, the rotating cylinder 222 drives the rotating rocker arm 223 to rotate 180°, so that the positions of the two product clamps 224 are swapped, which facilitates the loading and unloading grabbing mechanism 26 or the rotating material transporting mechanism 3 to grab the product; in actual work, when one of the product clamps 224 is placed with the product to be processed, the other product clamp 224 is placed with the processed product, so that the manipulator loading and unloading mechanism 2 is always in a continuous working state, thereby improving the processing efficiency of the fine grinder and reducing energy consumption.

[0045] The discharge mechanism 25 includes a discharge base plate 251 and a material tray 252. The discharge base plate 251 is slidably connected to the Y-axis module 24. The Y-axis module 24 can drive the discharge base plate 251 to move back and forth. The material tray 252 is detachably connected to the discharge base plate 251. The material tray 252 and the discharge base plate 251 are detachably connected to facilitate the removal of processed products and the placement of new products to be processed. When working, the Y-axis module 24 is controlled to move, thereby driving the material tray 252 to move to the designated position for loading or unloading operations.

[0046] The X-axis module 23 and the Y-axis module 24 can adopt any linear drive module in the prior art, which will not be described in detail herein.

[0047] The loading and unloading grabbing mechanism 26 includes a Z-axis fixing plate 261, a Z-axis cylinder 262, and a clamping cylinder 263. The Z-axis fixing plate 261 is slidably connected to the X-axis module 23. The Z-axis cylinder 262 and the clamping cylinder 263 are each connected to a controller. The Z-axis cylinder 262 is connected to the Z-axis fixing plate 261. The output end of the Z-axis cylinder 261 is fixedly connected to the clamping cylinder 263, and the output end of the clamping cylinder 263 is equipped with a clamping claw 264. During operation, the Z-axis cylinder 262 can drive the clamping cylinder 263 to move up and down, facilitating the clamping cylinder 263 to grab products from the material tray 252.

[0048] When the fully automatic step-difference fine grinding integrated equipment is loading, the controller controls the X-axis module 23 and the Y-axis module 24 to work respectively. The Y-axis module 24 drives the material tray 252 to move back and forth. When the material tray 252 reaches the predetermined loading position, the Y-axis module 24 stops working; the X-axis module 23 drives the upper and lower material grabbing mechanism 26 to move left and right. When the upper and lower material grabbing mechanism 26 reaches the predetermined loading position, the X-axis module 23 stops working, and then controls the Z-axis cylinder 262 to work. The Z-axis cylinder 262 drives the clamping cylinder 263 to descend. When the clamping cylinder 263 descends to a predetermined height, the clamping cylinder 263 drives the clamping cylinder 263 to descend. The claw 264 grabs the product from the material tray 252, then controls the Z-axis cylinder 262 to rise and reset, and then controls the X-axis module 23 to move until the loading and unloading grabbing mechanism 26 moves to directly above the product fixture 224, and then the Z-axis cylinder 262 drives the clamping cylinder 263 to descend, and the clamping cylinder 263 places the product on the product fixture 224, and then controls the rotating cylinder 222 to work, driving the rotating rocker 223 to rotate 180°, so that the positions of the two product fixtures 224 are swapped, and the rotating rocker 223 transports the product to be processed to directly below the rotating material transport mechanism 3 to complete the loading.

[0049] When the fully automatic step-difference fine grinding integrated equipment is unloading, the rotating material transport mechanism 3 places the processed product on the product fixture 224, controls the rotating cylinder 222 to work, and drives the rotating rocker 223 to rotate 180°, so that the positions of the two product fixtures 224 are swapped; then the Z-axis cylinder 262 is controlled to work, and the Z-axis cylinder 262 drives the clamping cylinder 263 to descend, and the clamping cylinder 263 grabs the processed product from the product fixture 224, and then the Z-axis cylinder 262 drives the clamping cylinder 263 to rise; then the X-axis module 23 and the Y-axis module 24 are controlled to move, and the upper and lower material grabbing mechanism 26 is driven to the predetermined unloading position, and then the Z-axis cylinder 262 works to drive the clamping cylinder 263 to descend, and the clamping cylinder 263 places the processed product on the material tray 252 to complete unloading.

[0050] In this embodiment, the loading and unloading process of the robot loading and unloading mechanism 2 is carried out continuously, that is, after completing one loading, it is followed by unloading, and after unloading is completed, it is followed by loading again, and this is repeated; the continuity of loading and unloading is ensured, and the processing efficiency is improved.

[0051] like Figure 4 、 5 As shown, the rotating material transport mechanism 3 includes a rotating table base 31 and a turntable 32. The rotating table base 31 is fixedly mounted on the machine 1. A material transport drive mechanism is provided on the rotating table base 31. The material transport drive mechanism is connected to the controller. The output end of the material transport drive mechanism is connected to the turntable 32. The material transport drive mechanism can drive the turntable 32 to rotate. Four material picking and unloading mechanisms 33 are distributed at 90° intervals on the outer wall of the turntable 32. The material picking and unloading mechanisms 33 are connected to the controller. The material picking and unloading mechanisms 33 are respectively connected to the rough grinding mechanism 4, the fine grinding mechanism 5, the step-by-step slotting mechanism 6 and the rotating module 22, and the positional relationship corresponds one to one. The material picking and unloading mechanisms 33 are used to transfer products between the rough grinding mechanism 4, the fine grinding mechanism 5, the step-by-step slotting mechanism 6 and the rotating module 22. When the rotating material transport mechanism 3 is working, the material transport drive mechanism drives the four picking and unloading mechanisms 33 to work simultaneously. The first picking and unloading mechanism 33 grabs the product from the product fixture 224 to the rough grinding processing mechanism 4, the second picking and unloading mechanism 33 grabs the product from the rough grinding processing mechanism 4 to the fine grinding processing mechanism 5, the third picking and unloading mechanism 33 grabs the product from the fine grinding processing mechanism 5 to the step-difference slotting mechanism 6, and the fourth picking and unloading mechanism 33 grabs the product from the step-difference slotting mechanism 6 to the product fixture 224.

[0052] In this embodiment, when the material picking and unloading mechanism 33 completes a grabbing operation, the controller controls the material transport drive mechanism to drive in reverse, driving the turntable 32 and the material picking and unloading mechanism 33 to rotate in the opposite direction, so that the material picking and unloading mechanism 33 can return to the initial position after completing a grabbing operation, and then repeat the material transport; that is, the movement stroke of each material picking and unloading mechanism 33 is: grab the product at the initial position → transport the product to the next mechanism → place the product on the next mechanism → return to the initial position.

[0053] The reason for the reset motion of the pick-up and unplacing mechanism 33 is to prevent the cables and air tubes within each pick-up and unplacing mechanism 33 from becoming entangled with each other and causing equipment failure. In other embodiments, the pick-up and unplacing mechanism 33 may not perform the reset motion and may directly rotate continuously 360°. In some of these embodiments, an electronic slip ring may be installed on the turntable base 31, and all cables and air tubes may be routed through the electronic slip ring to prevent the cable and air tube entanglement problem.

[0054] The material transport drive mechanism includes a material transport motor 34 and a hollow rotating platform 35. The material transport motor 34 is fixedly mounted on the rotating platform base 31 and is connected to a controller. The output end of the material transport motor 34 is connected to the input end of the hollow rotating platform 35, and the output end of the hollow rotating platform 35 is connected to the turntable 32. During operation, the material transport motor 34 drives the hollow rotating platform 35 to rotate, which in turn drives the turntable 32 and the material pick-up and discharge mechanism 33 to rotate. The material pick-up and discharge mechanism 33 works to grab products and transfer them between the rough grinding mechanism 4, the fine grinding mechanism 5, the step-slotting mechanism 6, and the rotating module 22.

[0055] The loading and unloading mechanism 33 includes a loading and unloading fixed plate 331, a loading and unloading cylinder 332, a clamping plate 333, and a clamping cylinder 334. The loading and unloading fixed plate 331 is connected to the turntable 32, and the loading and unloading cylinder 332 is fixedly mounted on the loading and unloading fixed plate 331. The clamping plate 333 is fixedly connected to the output end of the loading and unloading cylinder 332. The clamping cylinder 334 is fixedly mounted on the clamping plate 333, and the output end of the clamping cylinder 334 is equipped with a gripping finger 335. To grab or place a product, the loading and unloading cylinder 332 first drives the clamping plate 333 and the clamping cylinder 334 downward. Then, the clamping cylinder 334 activates, driving the gripping fingers 335 to grab or place the product.

[0056] The pick-up and discharge fixing plate 331 is provided with a pick-up and discharge guide mechanism, which is used to guide and limit the movement stroke of the clamping cylinder 334. The pick-up and discharge guide mechanism includes a pick-up and discharge guide sleeve 336, a pick-up and discharge guide rod 337 and a pick-up and discharge limit plate 338. The pick-up and discharge guide sleeve 336 is fixedly installed on the pick-up and discharge fixing plate 331, and the pick-up and discharge guide rod 337 extends into and passes through the pick-up and discharge guide sleeve 336, and the pick-up and discharge guide rod 337 is slidably limited and connected to the pick-up and discharge guide sleeve 336. The movement direction of the pick-up and discharge guide rod 337 and the pick-up and discharge cylinder 332 are parallel to each other. There are two pick-up and discharge guide rods 337, which are respectively located on the left and right sides of the pick-up and discharge cylinder 332. One end of the pick-up and discharge guide rod 337 is fixedly connected to the clamping fixed plate 333, and the other end is fixedly connected to the pick-up and discharge limit plate 338. When the material picking and unloading cylinder 332 is working, the clamping fixing plate 333 can drive the material picking and unloading guide rod 337 to slide in the material picking and unloading guide sleeve 336. Through the cooperation between the material picking and unloading guide rod 337 and the material picking and unloading guide sleeve 336, the movement stroke of the clamping cylinder 334 is guided.

[0057] A micrometer head 339 is mounted on the loading and unloading guide sleeve 337.

The rough grinding drill bit straightening rod 4113 is connected to the rough grinding straightening rod mounting block 4117. The rough grinding straightening rod mounting block 4117 is connected to one end of the rough grinding straightening pushing block 4116. The other end of the rough grinding straightening pushing block 4116 is a free end. The free end is used to connect an external thrust to push the rough grinding straightening pushing block 4116 to swing, thereby driving the rough grinding drill bit straightening rod 4113 to abut against the drill bit.

[0085] The rough grinding support frame 4201 is provided with a push rod fixing block 4230, on which a micrometer head 4231 is mounted. A push rod 4232 is mounted on the screw of the micrometer head 4231. During operation, the rough grinding feed mechanism drives the push rod 4232 toward the rough grinding clamping mechanism 41, causing the push rod 4232 to abut against the free end of the rough grinding centering push block 4116, thereby causing the rough grinding centering push block 4116 to swing. The rough grinding centering push block 4116 then moves the rough grinding centering rod mounting block 4117 and the rough grinding drill bit centering rod 4113. When the rough grinding feed mechanism stops driving, the push rod 4232 can push the rough grinding drill bit centering rod 4113 into abutment with the drill bit. The operator can adjust the extension length of the push rod 4232 by rotating the micrometer head 4231. By adjusting the extension length of the push rod 4232, the movement stroke of the rough grinding drill needle straightening rod 4113 is adjusted, so that the contact force of the rough grinding drill needle straightening rod 4113 on the drill needle is changed, ensuring the concentricity of the drill needle and the rod during processing. The micrometer head 4230 can use any micrometer head that can measure length in the existing technology. The micrometer head is provided with a scale, and the adjustment accuracy can reach 0.01 mm. Installing the push rod 4232 on the rough grinding support frame 4201 can ensure that the rough grinding drill needle straightening rod 4113 moves with the movement of the rough grinding wheel 4202, ensuring that the rough grinding drill needle straightening rod 4113 can resist the drill needle when the rough grinding wheel 4202 is performing grinding processing, thereby ensuring the concentricity of the drill needle and the rod.

[0086] A return spring 4118 is provided on the rough grinding straightening fixed block 4115. The return spring 4118 is used to drive the rough grinding straightening push block 4116 to return to its original position, thereby driving the rough grinding drill bit straightening rod 4113 to separate from the drill bit, which is convenient for cutting. One end of the return spring 4118 is fixedly connected to the rough grinding straightening fixed block 4115, and the other end is fixedly connected to one end of the rough grinding straightening push block 4116 close to the rough grinding straightening rod mounting block 4117. During operation, when the rough grinding feed mechanism drives the push rod 4232 to push the rough grinding straightening push block 4116 to swing, the push rod 41 The thrust of 32 is greater than the elastic force of the return spring 4118, so the rough grinding straightening push block 4116 will stretch the return spring 4118, causing the return spring 4118 to undergo elastic deformation; after the processing is completed, the rough grinding feed mechanism is reset, driving the push rod 4232 to move, so that it is separated from the rough grinding straightening push block 4116. At this time, under the action of the elastic force of the return spring 4118, the rough grinding straightening push block 4116 is pulled to reset and swing, thereby driving the rough grinding drill needle straightening rod 4113 to reset and move, so that it is separated from the drill needle, making it easier for the material taking and discharge mechanism 33 to grab and discharge the material.

[0087] The rough grinding straightening adjustment mechanism is arranged on the rough grinding straightening rod mounting block 4117, and the rough grinding straightening adjustment mechanism is used to adjust the installation position of the rough grinding drill needle straightening rod 4113, thereby adjusting the abutment position and strength between the rough grinding drill needle straightening rod 4113 and the drill needle.

[0088] Specifically, if Figure 12 As shown, a long strip slot 4119 is provided on the rough grinding straightening rod mounting block 4117, and a third limiting screw 4120 is provided on the long strip slot 4119.

After reaching the appropriate position, the third limit screw 4120 can be tightened again; the installation position of the rough grinding straightening rod mounting block 4117 is changed, and the abutment position of the rough grinding drill needle straightening rod 4113 and the drill needle is also changed.

[0089] A first through hole 4122 and a second through hole 4123 are provided on the rough grinding straightening rod mounting block 4117. The first through hole 4122 is connected to the second through hole 4123, and the first through hole 4122 and the second through hole 4123 are vertically distributed. An elevation adjustment block 4124 is provided in the first through hole 4122. The elevation adjustment block 4124 is clearance-matched with the first through hole 4122. A fourth limiting screw 4125 is provided on the rough grinding straightening rod mounting block 4117. The end face of the fourth limiting screw 4125 abuts against the side wall of the elevation adjustment block 4124, so that the elevation adjustment block 4124 is limited and fixed to the rough grinding straightening rod mounting block 4117; the elevation adjustment block 41 24 is provided with a third through hole 4126, and the rough-grinding drill needle straightening rod 4113 passes through the second through hole 4123 and the third through hole 4126 in sequence. The rough-grinding drill needle straightening rod 4113 is clearance-matched with the third through hole 4126. A fifth limiting screw 4127 is provided on the elevation adjustment block 4124, and the end face of the fifth limiting screw 4127 abuts against the rough-grinding drill needle straightening rod 4113, so that the rough-grinding drill needle straightening rod 4113 and the elevation adjustment block 4124 are limitedly connected and fixed. The inner diameter of the second through hole 4123 is larger than the outer diameter of the rough-grinding drill needle straightening rod 4113, so that the rough-grinding drill needle straightening rod 4113 can swing up and down in the second through hole 4123. When adjustment is needed, the user can loosen the fourth limit screw 4125, and the elevation adjustment block 4124 can rotate in the first through hole 4122, thereby driving the rough grinding drill bit straightening rod 4113 to swing up and down in the second through hole 4123, thereby adjusting the installation angle of the rough grinding drill bit straightening rod 4113, and then changing the abutment angle between the rough grinding drill bit straightening rod 4113 and the drill bit; loosen the fifth limit screw 4127, and the rough grinding drill bit straightening rod 4113 can slide in the second through hole 4123, thereby adjusting the length of the rough grinding drill bit straightening rod 4113 extending out of the rough grinding straightening rod mounting block 4117, thereby changing the abutment force of the rough grinding drill bit straightening rod 4113 on the drill bit. In order to facilitate the adjustment of the rough grinding drill bit straightening rod 4113, a handle 4128 is provided at one end of the rough grinding drill bit straightening rod 4113 away from the second wear-resistant block 4114. The handle 4128 is fixedly connected to the rough grinding drill bit straightening rod 4113 to facilitate manual adjustment by the user.

[0090] When the rough grinding clamping mechanism is loading, the material placement mechanism 33 places the product onto the ejector pin 4103, then controls the ejector cylinder 4102 to reset, driving the ejector pin 4103 and the product down to the processing position. At this point, the first wear-resistant block 4112 and the guide wheel 4105 are respectively in contact with the side wall of the bar stock. Next, the pressure roller cylinder 4106 is controlled to operate, driving the pressure roller connecting rod 4108 to move. The pressure roller connecting rod 4108 pushes the pressure roller swing rod 4109 to swing around the hinge point, thereby driving the pressure roller 4107 toward the guide wheel 4105 until the pressure roller 4107 contacts the side wall of the bar stock, completing the loading process. At this point, the bottom end of the bar stock is restrained by the ejector pin 4103, and the side wall of the bar stock is restrained and contacted with the first wear-resistant block 4112, the guide wheel 4105, and the pressure roller 4107.

[0091] During processing, the rough grinding feed mechanism is controlled to move toward the direction of the bar material, and the guide wheel motor 4104 is controlled to work at the same time; the rough grinding feed mechanism drives the push rod 4232 to move, so that the push rod 4232 abuts against the free end of the rough grinding straightening push block 4116, thereby pushing the rough grinding straightening push block 4116 to swing, and the rough grinding straightening push block 4116 pushes the rough grinding straightening rod mounting block 4117 and the rough grinding drill needle straightening rod 4113 to move until the second wear-resistant block 4114 abuts against the drill needle. At this point, the rough grinding wheel 4202 is in contact with the drill bit, grinding it. The second wear-resistant block 4114 supports the drill bit, preventing it from bending during machining and improving the concentricity between the drill bit and the stock. The guide wheel motor 4104 operates, driving the guide wheel 4105 to rotate. The guide wheel 4105 rotates the stock in place, while the pressure wheel 4107 rotates with the stock. This rotational processing ensures uniform grinding of the circumferential sidewall of the drill bit. The rough grinding straightening push block 4113 stretches the return spring 4118 as it swings, causing it to elastically deform.

[0092] After the processing is completed, the rough grinding feed mechanism is controlled to move away from the rod material, and the pressure wheel cylinder 4106 is controlled to work at the same time; the rough grinding feed mechanism drives the push rod 4232 to separate from the free end of the rough grinding straightening push block 4116. At this time, under the action of the elastic force of the reset spring 4118, the rough grinding straightening push block 4116 is pulled to reset and swing, thereby driving the rough grinding drill needle straightening rod 4113 to reset and move, so that the second wear-resistant block 4114 is separated from the drill needle; the pressure wheel cylinder 4106 drives the pressure wheel connecting rod 4108 to move, and the pressure wheel connecting rod 4108 pulls the pressure wheel rocker rod 4109 to swing with the hinge point as the axis, thereby driving the pressure wheel 4107 to move away from the guide wheel 4105 until the pressure wheel 4107 is separated from the rod material; then the controller controls the ejection cylinder 4102 to work, pushes the ejector pin 4103 and the processed product to rise, and then controls the material taking and discharging mechanism 33 to take the rough-ground product from the ejector pin 4103.

[0094] After the rough grinding mechanism 4 completes the grinding process, the material taking and discharging mechanism 33 grabs the product from the rough grinding clamping frame mechanism 41 and transports it to the fine grinding rod placement mechanism 53. The product is limited and fixed on the fine grinding rod placement mechanism 53 by the fine grinding rod limiting mechanism 58 and the fine grinding needle straightening mechanism 54, and the fine grinding wheel mechanism 55 and the fine grinding feed mechanism 56 are controlled to work respectively. The fine grinding wheel mechanism 55 drives the fine grinding wheel 5501 to rotate, and the fine grinding feed mechanism 56 drives the fine grinding support frame 5201 to move toward the direction close to the fine grinding clamping mechanism 51. The fine grinding support frame 5201 drives the fine grinding wheel mechanism 55 and the fine grinding wheel 5501 to move synchronously until the fine grinding wheel 5501 is connected with the product on the fine grinding rod placement mechanism 53, and the product is ground.

[0095] The fine grinding support frame 5201 is provided with a fine grinding lifting adjustment mechanism and a fine grinding angle adjustment mechanism. The fine grinding lifting adjustment mechanism is connected to the fine grinding wheel mechanism 55. The fine grinding lifting adjustment mechanism is used to adjust the horizontal height of the fine grinding wheel 5501. The fine grinding angle adjustment mechanism is connected to the fine grinding lifting adjustment mechanism. The fine grinding angle adjustment mechanism is used to adjust the horizontal elevation angle of the fine grinding wheel. Before work, the horizontal elevation angle and the horizontal installation height of the fine grinding wheel 5501 are adjusted respectively through the fine grinding angle adjustment mechanism and the fine grinding lifting adjustment mechanism according to actual conditions to ensure that the fine grinding wheel 5501 is accurately matched with the grinding surface of the product to be processed, thereby improving the processing accuracy.

[0096] The structure of the fine grinding wheel mechanism 55 is the same as that of the rough grinding wheel mechanism, and will not be repeated in this article; the structure of the fine grinding lifting adjustment mechanism is the same as that of the rough grinding lifting adjustment mechanism, and will not be repeated in this article; the structure of the fine grinding angle adjustment mechanism is the same as that of the rough grinding angle adjustment mechanism, and will not be repeated in this article.

A slider 5602 is provided at the output end of the feed drive mechanism. The slider 5602 is connected to the fine grinding support frame 5201. The displacement detection mechanism is connected to a controller and is used to detect the movement distance of the slider 5602. The displacement detection mechanism can detect the displacement distance of the slider 5602 in real time, thereby accurately controlling the displacement distance of the fine grinding wheel 5501 and ensuring grinding accuracy.

[0098] The feed drive mechanism includes a feed motor 5603, a reducer 5604 and a transmission screw 5605. The reducer 5604 is connected to the feed motor 5603 and the feed fixed seat 5601 respectively. The feed motor 5603 is connected to the controller. The output end of the feed motor 5603 is connected to the input end of the reducer 5604. The output end of the reducer 5604 is connected to the transmission screw 5605. The transmission screw 5605 is rotatably limited to the feed fixed seat 5601. The sliding member 5602 is threadedly connected to the transmission screw 5605. Part 5602 is slidably connected to the feed fixed seat 5601; during fine grinding, the controller controls the feed motor 5603 to work, and the feed motor 5603 drives the transmission screw 5605 to rotate through the reducer 5604. The rotation of the transmission screw 5605 drives the sliding part 5602 to slide on the feed fixed seat 5601, thereby driving the fine grinding support frame 5201 and the fine grinding wheel 5501 to move toward the fine grinding clamping mechanism 51 until the fine grinding wheel 5501 is connected with the product on the fine grinding clamping mechanism 51, and the product is ground.

[0099] The displacement detection mechanism includes a scale 5606 and a scale reader 5607. The scale 5606 is fixedly mounted on one side of the slider 5602, while the scale reader 5607 is fixedly mounted on the feed mount 5601 at a position corresponding to the scale 5606. The scale reader 5607 is connected to the controller. As the feed motor 5603 drives the slider 5602, the scale 5606 moves synchronously with it. The scale reader 5607 can detect the distance traveled by the scale 5606, thereby precisely controlling the travel of the slider 5602, improving the control accuracy of the feed of the fine grinding wheel 5501, and thus enhancing the accuracy of the grinding process.

[0100] A mounting plate 5202 is provided on the fine grinding support frame 5201, and a grinding wheel dressing mechanism 57 is provided on the mounting plate 5202. The grinding wheel dressing mechanism 57 is used to dress the fine grinding wheel 5501, thereby ensuring that the fine grinding wheel 5501 is always in the best processing state and improving the processing accuracy.

[0101] like Figure 15 As shown, the grinding wheel dressing mechanism 57 includes a bracket 5701, an adjusting frame 5702, a clamping block 5703 and a sanding strip 5704. One end of the bracket 5701 is hinged and fixed to the mounting plate 5202. An arc-shaped slide groove 5203 is provided on the mounting plate 5202. Two limiting bolts 5705 are provided on the side of the bracket 5701 away from the hinged end; tightening the limiting bolt 5705 can fix the limiting bolt 5705 to the arc-shaped slide groove 5203, thereby limiting and fixing the bracket 5701 to the mounting plate 5202; after loosening the limiting bolt 5705, the limiting bolt 5705 can slide in the arc-shaped slide groove 5203, thereby allowing the bracket 5701 to rotate on the mounting plate 5202. By cooperating with the limiting bolt 5705 and the arc-shaped slide groove 5203, the cooperation angle between the grinding wheel dressing mechanism 57 and the fine grinding wheel 5501 can be adjusted; specifically, under normal circumstances, the limiting bolt 5705 is in a tightened state. When the fine grinding wheel 5501 needs to be dressed, the limiting bolt 5705 can be loosened, so that the bracket 5701 can be rotated on the mounting plate 5202. After rotating to the appropriate angle, the limiting bolt 5705 is tightened again to limit and fix the bracket 5701 and the mounting plate 5202.

[0102] In order to accurately adjust the rotation angle of the bracket 5701 on the mounting plate 5202, an angle notch 5204 is provided on the connecting surface of the mounting plate 5202 with the bracket 5701; when the bracket 5701 is adjusted to rotate on the mounting plate 5202, the user can understand the rotation angle of the bracket 5701 by observing the numerical changes of the angle notch 5204 on the mounting plate 5202, thereby achieving precise adjustment control.

[0103] The adjusting frame 5702 is installed on the bracket 5701, and the adjusting frame 5702 can rotate horizontally on the bracket 5701. A dovetail seat 5706 is provided on the adjusting frame 5702, and the clamping block 5703 is slidingly connected to the dovetail seat 5706. The sanding bar 5704 and the clamping block 5703 are detachably connected. The sanding bar 5704 and the clamping block 5703 are detachably connected to facilitate the replacement of the sanding bar 5704. The clamping block 5703 slides on the dovetail seat 5706, thereby driving the sanding strip 5704 to move; specifically, a grinding wheel screw 5707 is provided on the clamping block 5703, and the grinding wheel screw 5707 is rotatably limitedly connected to the clamping block 5703, and an adjusting handle 5708 is provided at one end of the grinding wheel screw 5707, and the other end of the grinding wheel screw 5707 passes through the clamping block 5703 and is adjustably threadedly connected to the dovetail seat 5706; when correcting the fine grinding wheel 5501, the adjusting handle 5708 is rotated to drive the grinding wheel screw 5707 to rotate, so that the grinding wheel screw 5707 is screwed into the dovetail seat 5706, and the grinding wheel screw 5707 pushes the clamping block 5703 to move, thereby driving the sanding strip 5704 to move in the direction close to the fine grinding wheel 5501 until the sanding strip 5704 abuts against the fine grinding wheel 5501, thereby correcting the fine grinding wheel 5501.

[0104] In order to achieve precise adjustment of the movement distance of the sand bar 5704, a scale ring 5709 is provided on the circumferential surface of the outer wall of the adjustment handle 5708, and an indicator mark 5710 is provided on the clamping block 5703 at a corresponding position of the scale ring 5709; when the adjustment handle 5708 is rotated, the scale ring 5709 will rotate together, and by observing the changes in the scale on the indicator mark 5710 aligning with the scale ring 5709, the moving distance of the sand bar 5704 can be understood, thereby achieving precise adjustment.

[0105] In other embodiments, the scale ring 5709 can also be set on the clamping block 5703 and sleeved on the outside of the adjustment handle 5708, and the indicator mark 5710 is set on the adjustment handle 5708 at the corresponding position of the scale ring 5709.

[0106] When the fine grinding wheel 5501 needs to be trimmed, first loosen the limit bolt 5705 so that the bracket 5701 can rotate on the mounting plate 5202. By observing the angle notches 5204 on the mounting plate 5202, the rotation angle of the bracket 5701 can be accurately controlled. According to actual needs, the bracket 5701 is rotated to a suitable angle, and then the limit bolt 5705 is tightened so that the bracket 5701 and the mounting plate 5202 are fixed in position. Then, the grinding wheel screw 5707 is driven to rotate by turning the adjusting handle 5708. , so that the grinding wheel screw 5707 is screwed into the dovetail seat 5706, and the grinding wheel screw 5707 pushes the clamping block 5703 to move, thereby driving the sanding strip 5704 to move towards the fine grinding wheel 5501 until the sanding strip 5704 is connected to the fine grinding wheel 5501, and the fine grinding wheel 5501 is trimmed. By observing the changes in the value of the scale ring 5709 corresponding to the indicating notch 5710, the feed amount of the sanding strip 5704 can be accurately controlled to ensure that the fine grinding wheel 5501 can be quickly dressed.

[0107] The structure of the fine grinding bar material placement mechanism 53 is the same as that of the rough grinding bar material placement mechanism, which will not be repeated herein; the structure of the fine grinding bar material limiting mechanism 58 is the same as that of the rough grinding bar material limiting mechanism, which will not be repeated herein.

[0108] like Figure 17 As shown, the fine grinding needle straightening mechanism 54 includes a fine grinding straightening fixed block 5401, a pulling cylinder 5402, a pushing connecting rod 5403 and a fine grinding straightening rod mounting block 5404. The fine grinding straightening fixed block 5401 is fixedly connected to the fine grinding clamping base 5101, and the pulling cylinder 5402 is fixedly installed on the fine grinding straightening fixed block 5401. The pulling cylinder 5402 is connected to the controller, and the middle part of the pushing connecting rod 5403 is connected to the fine grinding straightening fixed block 5101. 401 is hinged, and the pushing connecting rod 5403 can swing back and forth with the hinge point as the axis. One end of the pushing connecting rod 5403 is fixedly connected to the output end of the pulling cylinder 5402, and the other end of the pushing connecting rod 5403 is fixedly connected to the fine grinding straightening rod mounting block 5404. A fine grinding drill needle straightening rod 5405 is provided on the fine grinding straightening rod mounting block 5404, and the fine grinding drill needle straightening rod 5405 and the fine grinding straightening rod mounting block 5404 are adjustable and limited. Before processing, the piston of the pulling cylinder 5402 is in an extended state. During fine grinding processing, the controller controls the pulling cylinder 5402 to work, and the piston of the pulling cylinder 5402 retracts to drive the pushing connecting rod 5403 to swing with the hinge point as the axis, and the pushing connecting rod 5403 drives the fine grinding straightening rod mounting block 5404 and the fine grinding drill needle straightening rod 5405 to move toward the direction close to the fine grinding rod placement mechanism 53 until the end of the fine grinding drill needle straightening rod 5405 abuts against the drill needle; after processing is completed, the controller controls the pulling cylinder 5402 to return to its position, driving the fine grinding drill needle straightening rod 5405 to separate from the drill needle, so as to facilitate the material taking and unloading mechanism 33 to grab the material.

[0109] The fine grinding drill needle centering rod 5405 is installed on the side of the drill needle away from the grinding surface, that is, during fine grinding, the fine grinding wheel 5501 and the fine grinding drill needle centering rod 5405 are respectively located on both sides of the drill needle; so that the fine grinding drill needle centering rod 5405 can play a role in supporting the drill needle during processing, preventing the drill needle from bending sideways, and ensuring the concentricity of the drill needle and the rod.

[0110] An adjusting fixing block 5406 is provided on the fine grinding and straightening fixing block 5401, and the adjusting fixing block 5406 is fixedly connected to the fine grinding and straightening fixing block 5401 by screws. A differential head 5407 is provided on the adjusting fixing block 5401. When the pulling cylinder 5402 drives the pushing connecting rod 5403 to move, the screw of the differential head 5407 can abut against one end of the pushing connecting rod 5403 close to the pulling cylinder 5402, thereby limiting the movement stroke of the pushing connecting rod 5403. When it is necessary to reduce the contact force of the fine-grinding drill needle straightening rod 5405 on the drill needle, the user can twist the differential head 5407 to extend the screw, that is, the extended length of the screw is increased, and the pushing connecting rod 5403 is limited by the screw of the differential head 5407 when it swings, so that the movement stroke of the pushing connecting rod 5403 is shortened, that is, the distance that the fine-grinding drill needle straightening rod 5405 moves forward is also shortened, so that the contact force of the fine-grinding drill needle straightening rod 5405 on the drill needle is reduced; conversely, retracting the screw into the differential head 5407 can expand the movement stroke of the pushing connecting rod 5403, thereby increasing the contact force of the fine-grinding drill needle straightening rod 5405 on the drill needle.

[0111] A fine grinding straightening adjustment mechanism is provided on the fine grinding straightening rod mounting block 5404, which is used to adjust the installation position of the fine grinding drill needle straightening rod 5405, thereby adjusting the contact position and strength between the fine grinding drill needle straightening rod 5405 and the drill needle.

[0112] The structure of the fine grinding straightening adjustment mechanism is the same as that of the coarse grinding straightening adjustment mechanism, so this article will not repeat it.

[0113] The fine grinding process is similar to the rough grinding process. The specific working process is as follows:

[0114] The material taking and unloading mechanism 33 places the rod material on the fine grinding rod material placement mechanism 53, and the fine grinding rod material limiting mechanism 58 limits the rod material on the fine grinding rod material placement mechanism 53, and drives the rod material to rotate in place; the pulling cylinder 5402 is controlled to work, and the piston of the pulling cylinder 5402 is retracted to drive the pushing connecting rod 5403 to swing with the hinge point as the axis, and the pushing connecting rod 5403 drives the fine grinding straightening rod mounting block 5404 and the fine grinding drill needle straightening rod 5405 to move toward the direction of the fine grinding rod placement mechanism 53 until the pushing connecting rod 5403 is close to one end of the pulling cylinder 5402 and abuts against the screw of the differential head 5407. The end of the straight rod 5405 also just contacts the drill needle, and the fine grinding drill needle straightening rod 5405 contacts the drill needle to prevent the drill needle from bending sideways during grinding, thereby ensuring the concentricity of the drill needle and the rod; then the feed motor 5603 is controlled to work, and the feed motor 5603 drives the transmission screw 5605 to rotate through the reducer 5604. The rotation of the transmission screw 5605 drives the sliding member 5602 to slide on the feed fixed seat 5601, thereby driving the fine grinding support frame 5201 and the fine grinding wheel 5501 to move toward the rod, until the fine grinding wheel 5501 is connected with the product on the fine grinding rod placement mechanism 53, and the product is ground.

[0115] In this embodiment, the mesh number of the coarse grinding wheel 4202 is 200-500 mesh, preferably 500 mesh; the mesh number of the fine grinding wheel 5501 is 1000-1500 mesh, preferably 1500 mesh.

[0116] like Figure 1 、 2 As shown, the step-difference slotting mechanism 6 includes a slotting clamping mechanism 61 and a third grinding mechanism 62. The slotting clamping mechanism 61 is connected to the rotating material transport mechanism 4 and is used to fix the product to be processed. The third grinding mechanism 62 includes a slotting support frame, a slotting grinding wheel mechanism, and a slotting feed mechanism. The slotting grinding wheel mechanism is connected to the slotting support frame, and the slotting grinding wheel mechanism is provided with a slotted grinding wheel. The slotting grinding wheel mechanism can drive the slotting grinding wheel to rotate. The slotting feed mechanism is installed on the machine 1, and the output end of the slotting feed mechanism is connected to the slotting support frame. The slotting feed mechanism is used to drive the slotting grinding wheel to connect with the product on the slotting clamping mechanism 61. The step-difference slotting mechanism 6 is used to grind an annular groove on the drill bit after rough grinding and fine grinding, so that a step layer is formed on the outer wall of the drill bit.

[0117] Specifically, after the fine grinding process is completed, the material picking and unloading mechanism 33 grabs the product from the fine grinding rod placement mechanism 53 and transports it to the slotting clamping mechanism 61. The product to be processed is limited and fixed by the slotting clamping mechanism 61, and the slotting clamping mechanism 61 can drive the product to rotate in place; the slotting feeding mechanism is controlled to work, and the slotting support frame and the slotting grinding wheel are driven to move toward the slotting clamping mechanism 61 until the slotting grinding wheel is connected to the product on the slotting clamping mechanism 61, and grinding is performed on the outer wall of the product until an annular step groove is ground on the outer wall of the product.

[0118] In this embodiment, the slotting clamping mechanism 61 has the same structure as the fine grinding clamping mechanism 51 and will not be described again herein. The third grinding mechanism 62 has the same structure as the first grinding mechanism 42 and will not be described again herein. In other embodiments, the slotting clamping mechanism 61 may also utilize the rough grinding mechanism 41, and the third grinding mechanism 62 may also utilize the second grinding mechanism 52.

[0119] The fully automatic step-down fine grinding integrated equipment also includes a circulating cooling system 7, which is used to provide coolant to cool the grinding wheels, rods and electric spindles on the rough grinding mechanism 4, the fine grinding mechanism 5 and the step-down grooving mechanism 6, thereby reducing the heat generated during grinding and taking away the debris generated by grinding to improve processing accuracy.

[0120] like Figure 1 、 2 As shown in Figures 1 and 2, the circulating cooling system 7 includes a reflux box 71 and a liquid outlet pipe 72. The reflux box 71 is connected to the controller, and the output ends of the reflux box 71 are respectively connected to the liquid outlet pipes 72. The liquid outlet pipes 72 are respectively installed on the rough grinding mechanism 4, the fine grinding mechanism 5 and the step-by-step slotting mechanism 6. The liquid outlet pipes 72 can flow out coolant to cool the grinding wheels, rods and electric spindles on the rough grinding mechanism 4, the fine grinding mechanism 5 and the step-by-step slotting mechanism 6. A control valve 73 is installed on each liquid outlet pipe 72, and the corresponding liquid outlet pipe 72 can be closed or opened by operating the control valve 73. A reflux trough 11 and a reflux pipe 12 are provided on the machine 1. The reflux trough 11 is arranged on the periphery of the rough grinding mechanism 4, the fine grinding mechanism 5 and the step-difference grooving mechanism 6. The height of the reflux trough 11 is lower than that of the rough grinding mechanism 4, the fine grinding mechanism 5 and the step-difference grooving mechanism 6. The reflux trough 11 is used to collect the coolant flowing out of the liquid outlet pipe 72. The reflux trough 11 is connected to one end of the reflux pipe 12, and the other end of the reflux pipe 12 is connected to the input end of the reflux box 71; the reflux box 71 is provided with a pumping device, a sedimentation box 74, a cooling device and a filtering device. The pumping device is used to drive the coolant in the reflux box 71 to flow, the sedimentation box 74 is used to precipitate impurities in the coolant, the cooling device is used to cool the coolant flowing into the reflux box 71, and the filtering device is used to filter and purify the coolant flowing into the reflux box 71.

[0121] When the fully automatic step-difference fine grinding integrated equipment is working, the coolant in the reflux box 71 flows out through the liquid outlet pipe 72 to cool the grinding wheel, workpiece, etc. on the corresponding processing mechanism. Then the coolant flows to the machine table 1, and under the action of gravity, it all flows into the reflux tank 11, and then all flows into the reflux pipe 12, and flows back into the reflux box 71 through the pipeline to form a closed-loop circulation system.

[0122] The cooling device includes a water chiller 75. The water chiller 75 is another name for a chiller. Simply put, the water chiller 75 is a machine that outputs low-temperature chilled water. The output chilled water temperature can be adjusted between 3-35° C. In other embodiments, the cooling device can also be a device or equipment that can cool liquid in the prior art.

[0123] The liquid extraction device includes two liquid extraction pumps 76, and the filtering device includes two filter barrels 77. The input ends of the two liquid extraction pumps 76 are respectively connected to the output ends of the sedimentation tank 74, and the output ends of the two filter barrels 77 are respectively connected to the input ends of the chiller 75. Each liquid extraction pump 76 is connected to a corresponding filter barrel 77 via a pipeline; that is, the two filter barrels 77 are connected in parallel, which can improve the filtering efficiency and ensure the outflow of the coolant. In other embodiments, the liquid extraction device can also be any other number of liquid extraction pumps 76, and the filtering device can also be any other number of filter barrels 77, or other devices or equipment capable of liquid filtration.

[0124] Specifically, the return pipe 12 is connected to the input end of the sedimentation tank 74, the output end of the sedimentation tank 74 is respectively connected to the input ends of the two liquid pumps 76, the output ends of the two liquid pumps 76 are respectively connected to the input ends of corresponding filter barrels 77, the output ends of the two filter barrels 77 are respectively connected to the input ends of the ice water machine 75, and the output ends of the ice water machine 75 are respectively connected to the input ends of the liquid outlet pipe 72.

[0125] When the fully automatic step-down fine grinding integrated equipment is working, the liquid pump 76 is controlled to work, driving the coolant in the reflux box 71 to flow, and the clean coolant flows out of the liquid outlet pipe 72 to cool the grinding wheels, rods and electric spindles on the rough grinding mechanism 4, the fine grinding mechanism 5 and the step-down grooving mechanism 6, so as to ensure the grinding accuracy of each mechanism; the used coolant flows into the reflux groove 11 under the action of gravity, and then flows into the reflux pipe 12 through the reflux groove 11, and finally flows back to the reflux box 71.

[0126] After entering the reflux box 71, the coolant first enters the sedimentation box 74. After entering the sedimentation box 74, larger debris will remain in the sedimentation box 74, which plays a role in preliminarily purifying the coolant; then the coolant is diverted into the filter barrel 77, and the coolant is further purified by the filter barrel 77, filtering out most of the impurities, debris, etc. in the coolant, thereby improving the cleanliness of the coolant and making it able to meet the requirements of secondary use; then it flows out of the filter barrel 77 and flows into the ice machine 75, and the coolant is cooled by the ice machine 75 to reduce the temperature of the coolant to meet the requirements of secondary processing; then it flows out of the ice machine 75 to the liquid outlet pipe 72, thereby forming a circulation loop of the coolant.

[0127] The working process of the fully automatic step-down fine grinding equipment is as follows:

[0128] First, the user places the product to be processed on the material tray 252, and the upper and lower material grabbing mechanism 26 grabs the product and places it on the rotating module 22. The rotating module 22 works to transport the product to be processed to the bottom of the rotating material transporting mechanism 4; the picking and discharging mechanism 33 is controlled to grab the product from the rotating module 22 and transport the product to the rough grinding clamping mechanism 41. The rough grinding feed mechanism and the rough grinding wheel mechanism drive the rough grinding wheel 4202 to perform the first grinding process on the product on the rough grinding clamping mechanism 41; after the first grinding process is completed, the picking and discharging mechanism 33 grabs the product from the rough grinding clamping mechanism 41 and transports the product to the fine grinding clamping mechanism 51. The fine grinding feed mechanism 56 and the fine grinding wheel mechanism 55 drive the fine grinding wheel 5501 to perform the first grinding process on the fine grinding clamping mechanism The product on the structure 51 is subjected to a second grinding process; after the second grinding process is completed, the picking and discharging mechanism 33 grabs the product from the fine grinding clamping mechanism 51 and transports the product to the slotting clamping mechanism 61, and the slotting feed mechanism and the slotting grinding wheel mechanism drive the slotting grinding wheel to perform a third grinding process on the product on the slotting clamping mechanism 61 until an annular step groove is ground on the outer wall of the product; after the step groove is processed, the picking and discharging mechanism 33 grabs the product from the slotting clamping mechanism 61 and transports the product to the rotating module 22, and the rotating module 22 works to transport the processed product to the unloading position, and the loading and unloading grabbing mechanism 26 grabs the product from the unloading position and transports the completed product to the material tray 252; at this point, the grinding process of the bar material is completed.

[0129] The fully automatic step-difference fine grinding integrated equipment is also suitable for processing ordinary ST-type micro drills. It only needs to remove the step-difference slotting mechanism 6 and install a fixture that can limit the installation of the bar material; or the step-difference slotting mechanism 6 can be controlled not to work.
