Description

Technical Field

[0001] The invention relates to the field of grinding and milling, and in particular to an intelligent grinding and milling device combined with laser. Background Art

[0002] Traditional milling and grinding equipment can be used to perform milling, grinding and other processes on workpieces. At the same time, its combination with laser milling can realize the processing of a variety of materials. When laser processing is required for bar stock, for example, the bar stock needs to be processed into a drill cutter, a milling cutter, etc., it is necessary to process both ends of the bar stock separately, so that one end of the bar stock is processed into a blade, and the other end is processed into a clamping part for installation. Most of the existing clamping devices process the other end after fixing one end, but if the other end of the bar stock needs to be processed, it needs to be manually re-clamped, which affects the processing efficiency.

[0003] The currently disclosed Chinese patent CN202110765972.X is a laser grinding and milling device, including a frame, a left-right motion mechanism, a two-axis motion mechanism, a laser head, a laser assembly, a left clamp, and a right clamp; the left-right motion mechanism is arranged on the frame; the two-axis motion mechanism is arranged on the frame; the laser head is arranged on the two-axis motion mechanism, and the two-axis motion mechanism drives the laser head to move in the up and down direction and the front and back direction; the laser assembly is connected to the laser head through an optical path assembly; the left clamp is arranged on the left-right motion mechanism, and the left-right motion mechanism drives the left clamp to move in the left and right directions, and the left clamp is provided with a left clamping opening, the left clamping opening faces the right side, and the left clamping opening is used to clamp the front end of the workpiece; the right clamp is arranged on the right side of the left clamp, and the right clamp is provided with a right clamping opening, the right clamping opening is used to clamp the rear end of the workpiece, the right clamp drives the workpiece to swing, and the swing axis of the workpiece is arranged along the front and back direction.

[0004] According to the above patent, when the workpiece is clamped, the workpiece can be placed on the right clamping opening on the right clamp, and the right clamp clamps the rear end of the workpiece so that the processing head can process the front end of the workpiece. After the front end of the workpiece is processed, the left clamp and the right clamp move relative to each other under the drive of the left and right movement mechanisms. The right clamp rotates around the axis of the front-to-back direction relative to the left and right movement mechanisms so that the front end of the workpiece is aligned with the left clamping opening on the left clamp. Under the drive of the left and right movement mechanisms, the workpiece enters from the right clamping opening in the right clamp into the left clamping opening of the left clamp. The right clamping opening releases the workpiece, and the left clamping opening clamps the workpiece, thereby realizing the reversal of the workpiece. However, this clamping method cannot guarantee the stability of the workpiece during processing. Although it replaces manual clamping, the stability is not high, and the patent does not have a device for processing iron chips. The processed iron chips fall on the left and right movement mechanisms and easily cause inconvenience in movement. Therefore, there is a need for a fixing device that can maintain the stability of the workpiece clamping, prevent iron chips from falling into it, and automatically convert the end of the workpiece.

[0042] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] like Figure 1-Figure 6 As shown, this application provides:

[0044] A laser-integrated intelligent grinding and milling device comprises a processing table 1 and a fixing device 2 arranged on the processing table 1 for fixing a workpiece 1a, the workpiece 1a is in a rod-shaped structure, and a laser grinding and milling robot 3 for processing the workpiece 1a is also provided on the processing table 1, the fixing device 2 comprises a support frame 2a and a first clamping mechanism 2b arranged on the support frame 2a for clamping the end of the workpiece 1a, and a second clamping mechanism 2c arranged on the processing table 1 and located above the first clamping mechanism 2b for clamping the body of the workpiece 1a, the second clamping mechanism 2c can drive the workpiece 1a to move, and an active adjustment mechanism 2d for driving the second clamping mechanism 2c to move is also provided on the processing table 1, and an iron chip processing device 4 for cleaning waste is also provided at the top of the active adjustment mechanism 2d.

[0045] Based on the above embodiments, the technical problem that the present application intends to solve is how to ensure the stability of the workpiece 1a during processing. To this end, the present application fixes the workpiece 1a by means of a fixing device 2, and the operator inserts one end of the workpiece 1a into the first clamping mechanism 2b through the iron chip processing device 4 and the second clamping mechanism 2c in turn. The first clamping mechanism 2b fixes the end of the workpiece 1a, and the second clamping mechanism 2c fixes the body of the workpiece 1a. The iron chip processing device 4 is located at the upper half of the workpiece 1a. Then, the laser milling robot 3 processes the end of the fixed workpiece 1a by means of laser. As the end of the workpiece 1a is processed, the iron chips falling from it fall into the iron chip processing device 4, and the iron chip processing device 4 then guides the iron chips out. When one end of the workpiece 1a is processed, the iron chip processing device 4 moves away from the workpiece 1a, and the first clamping mechanism 2b releases the workpiece 1a, while the second clamping mechanism 2c still clamps the workpiece 1a. As the movable adjustment mechanism 2d drives the second clamping mechanism 2c The workpiece 1a moves upward, and the end of the workpiece 1a moves out from the first clamping mechanism 2b. The movable adjusting mechanism 2d then drives the second clamping mechanism 2c to rotate 180°, and the workpiece 1a is replaced at one end. The unprocessed end of the workpiece 1a is vertically facing upward. Then, the movable adjusting mechanism 2d moves the processed end of the workpiece 1a to the first clamping mechanism 2b for continued fixation, and the iron chip processing device 4 also returns to its original position. The laser grinding and milling robot 3 processes the end of the workpiece 1a again. When the body of the workpiece 1a needs to be processed, the movable adjusting mechanism 2d can drive the second clamping mechanism 2c to move up and down, thereby driving the workpiece 1a to move upward step by step, so that the body of the workpiece 1a is exposed little by little for processing by the laser grinding and milling robot 3. Finally, both ends and the body of the workpiece 1a are processed to obtain a complete finished product, and the operator takes it out.

[0046] Further, such as Figure 6 and Figure 8 As shown:

[0047] The first clamping mechanism 2b includes a four-jaw chuck 2b1, a fixed ring 2a1 is provided on the top of the support frame 2a, and the four-jaw chuck 2b1 is rotatably set on the fixed ring 2a1 through an annular opening. A ring gear 2b2 is fixedly sleeved on the four-jaw chuck 2b1, and a driving gear 2b3 is meshed on the side of the ring gear 2b2. A first rotating driver 2b4 is also fixedly provided on the side wall of the support frame 2a to drive the driving gear 2b3 to rotate.

[0048] Based on the above embodiments, the technical problem that the present application wants to solve is how the first clamping mechanism 2b clamps the workpiece 1a. To this end, the present application clamps the workpiece 1a by a four-jaw chuck 2b1. After the end of the workpiece 1a is inserted into the four-jaw chuck 2b1, the four-jaw chuck 2b1 clamps the workpiece 1a through the claws. In order to cooperate with the processing of the laser grinding and milling robot 3, the four-jaw chuck 2b1 can drive the workpiece 1a to rotate, and the first rotary driver 2b4 drives the driving wheel to rotate. Since the driving wheel and the ring gear 2b2 are meshed with each other, the four-jaw chuck 2b1 rotates on the support frame 2a to drive the workpiece 1a to rotate, so that all parts of the workpiece 1a can be processed.

[0049] Further, such as Figure 7 As shown:

[0050] A cylindrical opening is provided in the center of the four-jaw chuck 2b1 from top to bottom, and the diameter of the cylindrical opening is larger than the diameter of the workpiece 1a. An elastic clamping plate 2b11 is also provided around the inner wall of the cylindrical opening of the four-jaw chuck 2b1 to tighten the workpiece 1a.

[0051] Based on the above embodiment, when the end of the workpiece 1a extends into the four-jaw chuck 2b1, if the workpiece 1a is too long, the workpiece 1a can extend downward through the cylindrical opening so that the upper end of the workpiece 1a does not protrude too much, thereby avoiding the situation where the lower half of the workpiece 1a is clamped while the upper half is not clamped, resulting in unstable processing. After the end of the workpiece 1a is inserted into the cylindrical opening, the workpiece 1a is wrapped by multiple elastic clamping plates 2b11 and obtains a clamping force, so that the workpiece 1a is stabilized when placed on the four-jaw chuck 2b1, and the four-jaw chuck 2b1 then clamps the workpiece 1a.

[0052] Further, such as Figure 6 and Fig. 9 As shown:

[0053] The second clamping mechanism 2c includes a movable disc 2c1, which is arranged on the movable adjusting mechanism 2d. Two double-axis double-rod cylinders 2c2 are symmetrically arranged on the top of the movable disc 2c1. A through hole with a diameter larger than the diameter of the workpiece 1a is provided in the center of the movable disc 2c1 from top to bottom. The output end of each double-axis double-rod cylinder 2c2 faces the through hole. The symmetry plane of the two double-axis double-rod cylinders 2c2 is the middle cross-section of the movable disc 2c1, and a clamping member 2c3 for clamping the workpiece 1a is also provided on the output end of each double-axis double-rod cylinder 2c2.

[0054] Based on the above embodiments, the technical problem that the present application intends to solve is how the second clamping mechanism 2c clamps the body of the workpiece 1a. To this end, the present application clamps the workpiece 1a by two double-axis double-rod cylinders 2c2. After the ends of the workpiece 1a are clamped, the body of the workpiece 1a is located between the two double-axis double-rod cylinders 2c2. The two double-axis double-rod cylinders 2c2 simultaneously drive the corresponding clamping members 2c3 to push toward the direction of the workpiece 1a, and the workpiece 1a is clamped by the two clamping members 2c3.

[0055] Further, such as Fig.10 and Fig.11 As shown:

[0056] The clamping member 2c3 is specifically a clamping block 2c31 with a clamping opening, and a clamping strip 2c32 is provided on the side of the clamping block 2c31 away from the clamping opening. A rectangular plate 2c33 is provided on the output end of the double-axis double-rod cylinder 2c2, and a clamping groove matching the shape of the clamping strip 2c32 is opened on the rectangular plate 2c33. The clamping block 2c31 is inserted into the clamping groove of the rectangular plate 2c33 through the clamping strip 2c32, and the rectangular plate 2c33 and the clamping block 2c31 are fixed by a first positioning pin 2c34.

[0057] Based on the above embodiment, the clamping block 2c31 on each double-axis double-rod cylinder 2c2 can be replaced. Different clamping blocks 2c31 can be replaced according to the shape of the workpiece 1a, so that the clamping of the workpiece 1a is more stable. When the clamping block 2c31 is replaced, the operator pulls out the first positioning pin 2c34, and the clamping block 2c31 is then pulled out from the slot on the rectangular plate 2c33. After replacing the clamping block 2c31, the first positioning pin 2c34 is inserted to stabilize the clamping block 2c31.

[0058] Further, such as Figure 6 and Fig.10 As shown:

[0059] A first guide column 2c4 is provided at the opening of the movable disc 2c1 for guiding the workpiece 1a. A guide opening that is coaxial with the opening and matches the shape of the workpiece 1a is provided on the first guide column 2c4. Two fan-shaped openings are also provided on the movable disc 2c1, and the first guide column 2c4 is fixed to the movable disc 2c1 by passing through the fan-shaped openings through the second positioning pin 2c41.

[0060] Based on the above embodiment, when the end of the workpiece 1a passes through the opening of the movable disc 2c1, the workpiece 1a extends downward through the guide opening of the first guide column 2c4 installed thereon, so that the workpiece 1a can remain in a vertical state when placed on the four-jaw chuck 2b1. The first guide column 2c4 can be replaced according to the shape of the workpiece 1a to ensure that the workpiece 1a can smoothly pass through the matching guide opening. When replacing the first guide column 2c4, the operator pulls out the second positioning pin 2c41, then takes out the first guide column 2c4, and after the replacement is completed, the second positioning pin 2c41 is inserted back to fix the first guide column 2c4.

[0061] Further, such as Fig. 9 As shown:

[0062] The movable adjustment mechanism 2d includes a lifting block 2d1 arranged on both sides of the movable disc 2c1. The movable disc 2c1 can rotate between the two lifting blocks 2d1. The lifting block 2d1 is also provided with a second rotation driver 2d11 for driving the movable disc 2c1 to rotate. The sides of each lifting block 2d1 are also symmetrically provided with two strip frames 2d2 in a vertical state. Each strip frame 2d2 is provided with a guide rod 2d21 along its length direction, and one of the guide rods 2d21 is a threaded rod 2d22. Each lifting block 2d1 is slidably mounted on the corresponding guide rod 2d21 and the threaded rod 2d22 through a slider 2d23, and the processing table 1 is also provided with a third rotation driver 2d24 for driving the threaded rod 2d22 to rotate.

[0063] Based on the above embodiments, the technical problem that the present application wants to solve is how the movable adjustment mechanism 2d drives the workpiece 1a to move. To this end, the present application drives the movable disc 2c1 to rotate through the second rotary driver 2d11, and the workpiece 1a is clamped by two clamps 2c3 and rotates with the movable disc 2c1. When one end of the workpiece 1a is processed, the third rotary driver 2d24 drives the threaded rod 2d22 to rotate, and the lifting block 2d1 is driven by the slider 2d23 to complete the lifting and moving. As the four-claw chuck 2b1 is relaxed, the workpiece 1a is lifted up little by little. After the body of the workpiece 1a is processed, the lower end of the workpiece 1a also leaves the four-claw chuck 2b1. As the movable disc 2c1 rotates 180°, the workpiece 1a also rotates 180°. The processed end of the workpiece 1a faces downward, and the unprocessed end of the workpiece 1a faces upward to wait for processing.

[0064] Further, such as Fig.12 and Fig.13 As shown:

[0065] The iron chip processing device 4 includes a top plate 4a arranged at the top end of four strip frames 2d2 and a funnel 4b arranged on the top plate 4a. The small head end of the funnel 4b faces upward and a circular ring 4a1 is also arranged around the top of the top plate 4a. A chip discharge port 4a11 is opened on the side wall of the circular ring 4a1. The diameter of the small head end of the funnel 4b is larger than the diameter of the workpiece 1a. A second guide column 4b1 with the same structure as the first guide column 2c4 is also arranged on the small head end of the funnel 4b. The second guide column 4b1 is fixed to the funnel 4b by a third positioning pin 4b2. The top plate 4a can also move vertically on the strip frame 2d2, and a lifting mechanism 4c for driving the top plate 4a to move is also provided on the strip frame 2d2.

[0066] Based on the above embodiments, the technical problem that the present application intends to solve is how to clean the iron chips processed on the workpiece 1a. To this end, the present application covers the workpiece 1a by means of a funnel 4b, so that the iron chips fall into the funnel 4b. The small end of the funnel 4b is sleeved on the workpiece 1a through a second guide column 4b1, which further stabilizes the workpiece 1a and prevents the iron chips from falling between the small end of the funnel 4b and the workpiece 1a. The iron chips fall between the ring 4a1 and the funnel 4b. When the workpiece 1a is processed, the operator sucks out the iron chips through the chip discharge port 4a11 on the ring 4a1. The funnel 4b can realize the lifting movement through the lifting mechanism 4c, and can adjust the height according to the length of the workpiece 1a, so that the funnel 4b always covers the upper half of the workpiece 1a.

[0067] Further, such as Fig.13 As shown:

[0068] The lifting mechanism 4c includes vertical frames 4c1 arranged around the top plate 4a, each vertical frame 4c1 can slide on the corresponding strip frame 2d2, and a sleeve 4a2 is opened on the top plate 4a at each strip frame 2d2 to be sleeved on the corresponding strip frame 2d2, a bellows 4c2 is connected between the bottom end of each vertical frame 4c1 and the bottom end of the corresponding strip frame 2d2, and an electromagnet 4c3 is also provided on the bottom end of each vertical frame 4c1 and the bottom end of the corresponding strip frame 2d2.

[0069] Based on the above embodiment, when the lifting mechanism 4c drives the funnel 4b to adjust its height, the magnitude of the magnetic force between the two electromagnets 4c3 changes, so that the vertical frame 4c1 can slide on the strip frame 2d2, and the top plate 4a also drives the funnel 4b to rise and fall, ensuring that the funnel 4b is in the upper half of the workpiece 1a, so that the iron filings finally fall on the funnel 4b.

[0070] Further, such as Figure 6 As shown:

[0071] It also includes a supporting mechanism 5 for supporting the workpiece 1a, the supporting mechanism 5 includes a supporting plate 5a, a flat plate is provided on the lower half of the supporting frame 2a, a socket is provided on the flat plate coaxially with the four-jaw chuck 2b1, the supporting plate 5a is coaxially inserted in the socket through an insert rod 5b, and a buffer spring 5c ​​is also sleeved on the insert rod 5b and located between the supporting plate 5a and the flat plate.

[0072] Based on the above embodiment, when the end of the workpiece 1a extends into the cylindrical opening of the four-jaw chuck 2b1, the end of the workpiece 1a is supported on the support plate 5a, and the support plate 5a enables the end of the workpiece 1a to obtain supporting force. Since the support plate 5a is connected to the flat plate through the buffer spring 5c, the support plate 5a can always provide support for the end of the workpiece 1a.

[0073] The present application achieves stability of the workpiece 1a during processing and automatic conversion of the end of the workpiece 1a through the operation of the first clamping mechanism 2b, the second clamping mechanism 2c and the movable adjustment mechanism 2d on the workpiece 1a, thereby improving the processing efficiency of the workpiece 1a. The iron chips are collected by the iron chip processing device 4 to avoid the iron chips falling into the first clamping mechanism 2b and the second clamping mechanism 2c to affect the clamping of the workpiece 1a, thereby achieving the fixation of the workpiece 1a while also processing the iron chips.

[0074] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
