Description

Technical Field

[0001] This invention relates to the field of grinding technology, specifically to a titanium alloy grinding device that prevents waste from splashing. Background Technology

[0002] Grinding, a machining process, belongs to finishing (machining is divided into roughing, finishing, heat treatment, etc.). It involves a small amount of machining and high precision. It is widely used in the machinery manufacturing industry. When grinding carbon tool steel and carburized and quenched steel parts that have undergone heat treatment and quenching, a large number of regularly arranged cracks often appear on the surface that is basically perpendicular to the grinding direction—grinding cracks. These cracks not only affect the appearance of the parts, but more importantly, they directly affect the quality of the parts.

[0003] However, existing technologies cannot automatically open and close the barrier door of the processing device when grinding titanium alloys, requiring the operator to open and close it manually. If the barrier door is not closed, the debris and sparks inside the processing device may cause injury to the operator. To address this problem, it is necessary for those skilled in the art to develop a titanium alloy grinding device that prevents waste from splashing. Summary of the Invention

[0004] To address the aforementioned problems, the present invention provides a titanium alloy grinding apparatus that prevents waste from splashing.

[0005] The technical solution of the present invention is: a titanium alloy grinding device for preventing waste splashing, comprising a box with an opening on one side, a barrier door assembly disposed in the opening, and a titanium alloy placement assembly disposed inside the box.

[0006] The barrier door assembly includes a screw with one end rotatably connected to the inner wall of the housing, a gear rotatably disposed on the inner wall of the housing and fixedly connected to the other end of the screw, a first rack and a second rack respectively meshing with the top and bottom of the gear, two barrier doors slidably disposed in the opening and fixedly connected to the first rack and the second rack respectively, and a first motor disposed on the inner wall of the housing for driving the screw to rotate.

[0007] The titanium alloy placement assembly includes a connecting block threaded onto the screw, a placement platform slidably disposed inside the housing and fixedly connected to the connecting block, and a clamping assembly disposed on the placement platform for clamping the titanium alloy.

[0008] Description: This invention can automatically seal the housing with the barrier door when the titanium alloy workpiece is being ground inside the device, thus achieving the effect of sealing and protecting the device without the need for manual sealing. This prevents debris and sparks from flying out during the grinding process and causing injury to the workers.

[0009] Furthermore, the screw is hollow inside and has a spline rod inserted into it. The spline rod passes through the housing and is connected to a knob on the outside of the housing. The gear is connected to the spline rod.

[0010] Note: The above settings allow staff to manually control the opening and closing of the barrier door using a knob, making it convenient for staff to change the opening and closing method of the barrier door according to usage needs, thus improving the applicability of the device.

[0011] Furthermore, the screw is provided with a first spline and a second spline, and a first sleeve that engages with the first spline and a second sleeve that is disposed between the first spline and the second spline and can engage with the second spline are slidably sleeved on the screw. The top of the housing is provided with a sliding groove, and the top of each of the two barrier doors is provided with a slider that is slidably connected to the sliding groove. An air column is provided between the two sliders. An airbag column that is connected to the air column through a pipe is provided between the first sleeve and the second sleeve, and the airbag column is rotatably limited connected to both the first sleeve and the second sleeve. The gear is threadedly connected to the first sleeve, and the second sleeve is threadedly connected to the connecting block.

[0012] Note: Compared to controlling the opening and closing of the placement platform and the barrier door simultaneously on the same drive end, the use of the first spline, the second spline, the first sleeve, and the second sleeve allows for greater freedom in the opening and closing of the placement platform and the barrier door. This means that the position of the placement platform and the opening / closing state of the barrier door can be adjusted separately according to usage requirements, effectively improving the applicability of the device.

[0013] Furthermore, electromagnets are provided on the contact surfaces of the two barrier doors, a spring is provided between the slider and the slide groove, and a push switch is provided on the side wall of the box that can trigger a brief power outage of the electromagnets during the reset process of the placement platform;

[0014] Note: The above setup allows the second spline and the second sleeve to detach when the magnetic attraction is lost, thereby opening the barrier door to allow the workpiece to be removed.

[0015] Furthermore, the barrier door is provided with ball bearings on its side;

[0016] Note: The above setting can transform the sliding friction of the barrier door during its movement into rolling friction under the action of the ball bearings, thereby reducing friction, improving the smoothness and efficiency of the barrier door's sliding, and further enhancing the sealing effect on the enclosure.

[0017] Furthermore, the clamping assembly includes mounting plates disposed on both sides of the placement platform, a threaded tube disposed between the two mounting plates with reversed threads on both sides, clamping members threaded to both sides of the threaded tube respectively, and a second motor disposed on the outside of the mounting plates with its output shaft connected to the threaded tube.

[0018] Note: The above settings enable effective clamping of titanium alloy workpieces and improve grinding efficiency.

[0019] Furthermore, the placement platform is composed of several placement plates and a frame. The placement plate includes several plates with rotating shafts at both ends. The rotating shafts pass through the frame and are rotatably connected to the first limiting block at their ends. The threaded tube passes through the mounting plate and is rotatably connected to the second limiting block. The first limiting block and the second limiting block are connected by a first transmission belt. The rotating shafts are connected by a second transmission belt.

[0020] Note: The above setup utilizes the rotation of the threaded tube to effectively clamp the workpiece while tilting the plate to remove and clean residual debris from the surface of the placement plate, thus preventing grinding residue from leaving on the surface of the placement plate and adversely affecting the titanium alloy workpiece.

[0021] Furthermore, an observation window is installed on the barrier door, and a control panel for starting and stopping the first motor and the second motor is fixedly installed on one side of the housing;

[0022] Note: The above settings facilitate workers' observation of the grinding process, thereby improving grinding efficiency.

[0023] Compared with existing grinding devices, the advantages of this invention are:

[0024] (1) By setting threaded rods and gears, after the clamping component clamps and fixes the titanium alloy workpiece, the operator can control the first motor to work through the control panel, so as to seal the barrier door to the main body of the device, thereby achieving the effect of automatically sealing and protecting the device. The operator does not need to manually seal the barrier door, which prevents the operator from forgetting to seal it, resulting in the titanium alloy workpiece being ground inside the device and causing debris and sparks to fly out and injure the operator.

[0025] (2) The present invention achieves the opening and closing of the barrier door by setting the first spline, the second spline, the first sleeve, the second sleeve, the airbag column, and the air column in a linkage manner, while also allowing the barrier door and the placement platform to have degrees of freedom. The barrier door and the placement platform can be adjusted separately, which makes it convenient for staff to make changes according to the needs of use and improves the applicability of the device.

Detailed Implementation

[0034] To further illustrate the methods and effects of this invention, the technical solution of this invention will be clearly and completely described below in conjunction with experiments.

[0035] Example 1: As Figures 1-3 As shown, a titanium alloy grinding device for preventing waste splashing includes a housing 1 with an opening on one side, a barrier door assembly 2 disposed in the opening, and a titanium alloy placement assembly 3 disposed inside the housing 1.

[0036] The barrier door assembly 2 includes a screw 21 with one end rotatably connected to the inner wall of the housing 1, a gear 22 rotatably disposed on the inner wall of the housing 1 and fixedly connected to the other end of the screw 21, a first rack 23 and a second rack 24 respectively meshing with the top and bottom of the gear 22, two barrier doors 25 slidably disposed in the opening and fixedly connected to the first rack 23 and the second rack 24 respectively, and a first motor disposed on the inner wall of the housing 1 for driving the screw 21 to rotate;

[0037] The screw 21 is hollow inside and has a spline rod 211 inserted into it. The spline rod 211 passes through the housing 1 and is connected to the knob 11 on the outside of the housing 1. The gear 22 is connected to the spline rod 211.

[0038] The titanium alloy placement assembly 3 includes a connecting block 31 threaded onto the screw 21, a placement platform 32 slidably disposed inside the housing 1 and fixedly connected to the connecting block 31, and a clamping assembly 33 disposed on the placement platform 32 for clamping the titanium alloy.

[0039] The clamping assembly 33 includes mounting plates 331 disposed on both sides of the placement platform 32, a threaded tube 332 disposed between the two mounting plates 331 with reversed threads on both sides, clamping members 333 respectively threaded to both sides of the threaded tube 332, and a second motor disposed on the outside of the mounting plate 331 with its output shaft connected to the threaded tube 332.

[0040] An observation window 250 is installed on the barrier door 25, and a control panel 15 for starting and stopping the first motor and the second motor is fixedly installed on one side of the housing 1.

[0041] The working principle of this embodiment is as follows: When the operator needs to grind the titanium alloy, the operator can first control the first motor to work through the control panel 15, so that the first motor drives the screw 21 to rotate, and then the screw 21 drives the placement table 32 to move along the inside of the box 1 through the connecting block 31 until the placement table 32 moves to a position close to the barrier door 25 and stops. During this process, the screw 21 will drive the gear 22 to rotate, and the gear 22 will drive the first rack 23 and the second rack 24 to rotate, and then the first rack 23 and the second rack 24 will drive the corresponding barrier doors 10 to move away from each other, opening the seal on the box 1, so as to achieve the effect of automatically opening the barrier door 25, allowing the operator to place the titanium alloy workpiece to be ground on the clamping assembly 33 on the placement table 32;

[0042] Then, the operator can control the second motor via control panel 15, causing it to move the clamping member 333 through the threaded tube 332. This clamping member 333 clamps and fixes the titanium alloy workpiece, achieving a quick clamping and fixing effect. This facilitates the operator in fixing or stopping the fixing of the titanium alloy workpiece. Next, the operator can control the first motor to reverse its operation via control panel 15, causing the first motor to drive the screw 21 to rotate in the opposite direction. This causes the screw 21 to drive the placement platform 32 to reset via connecting block 31. The reverse rotation of the screw 21 also drives the gear 22 to rotate in the opposite direction, causing the gear 22 to drive the first rack 23 and the second rack 24 to move and reset. This causes the first rack 23 and the second rack 24 to move and lock the corresponding barrier doors 25 together, sealing the housing 1 and achieving automatic loading / unloading. The device provides a sealing protection effect, eliminating the need for manual sealing of the barrier door 25. This prevents workers from forgetting to seal the barrier door 25 or failing to completely seal it, which could cause debris and sparks to fly out during grinding of titanium alloy workpieces inside the device, potentially injuring workers. When the automatic opening and closing of the barrier door 25 is not needed, the worker can rotate the knob 11, causing the spline rod 211 to move along the thread extension direction inside the housing 1. This disengages the spline rod 211 from the screw 21, preventing the screw 21 from driving the gear 22 through the spline rod 211, thus stopping the automatic opening and closing of the barrier door 25. The worker can then manually pull the barrier door 25 to open and close it, allowing for easy modification according to usage needs and expanding the device's applicability.

[0043] Example 2: Unlike Example 1, as follows Figure 4 As shown, the screw 21 is provided with a first spline 216 and a second spline 212. A first sleeve 213, which engages with the first spline 216, and a second sleeve 214, which is located between the first spline 216 and the second spline 212 and can engage with the second spline 212, are slidably sleeved on the screw 21. The top of the housing 1 is provided with a sliding groove 10. The tops of the two barrier doors 25 are each provided with a slider 12 that is slidably connected to the sliding groove 10. An air column 13 is provided between the two sliders 12. An airbag column 215, which is connected to the air column 13 through a pipe, is provided between the first sleeve 213 and the second sleeve 214. The airbag column 215 is rotatably limited connected to both the first sleeve 213 and the second sleeve 214. The gear 22 is threadedly connected to the first sleeve 213, and the second sleeve 214 is threadedly connected to the connecting block 31. It should be noted that... Figure 4 The above components are in their initial positional relationship;

[0044] The working principle of this embodiment is basically the same as that of embodiment 2, except that the automatic door closing is as follows: In the initial state, the first spline 216 is engaged with the first sleeve 213, and the second spline 212 is not in contact with the second sleeve 214. The first motor is driven, and the screw 21 rotates, which drives the first rack 23 and the second rack 24 to move and close the barrier door 25. At the same time, the first rack 23 and the second rack 24 will squeeze the air column 12 during their opposite movement. When the barrier doors 25 on both sides are about to contact, the barrier door 25 is quickly closed under the action of the electromagnet 251. At this time, the air column 215 will expand, causing the first sleeve 213 to fall off the first spline 216, and the second sleeve 214 to engage with the second spline 212. At this time, the screw 21 rotates while the first sleeve 213 does not rotate, that is, the barrier door 25 remains in the closed state. The position of the placement table 32 can continue to be adjusted by the first motor driving the screw 21, so that the grinding machine can accurately align with it for processing.

[0045] Example 3: Unlike Example 2, as follows Figures 5-6 As shown, electromagnets 251 are provided on the contact surfaces of the two barrier doors 25, and springs 252 are provided between the slider 12 and the slide groove 10. A push switch 14 is provided on the side wall of the box body 1, which can trigger the electromagnets 251 to cut off power for 3 seconds during the reset process of the placement platform 32. Among them, reset means that the placement platform 32 moves to its initial position, that is, the side close to the opening of the box body 1. In this embodiment, the push switch 14 is a commercially available push button switch (normally open type), which cuts off power when pressed and turns on power when released.

[0046] The working principle of this embodiment is basically the same as that of embodiment 2. The difference is that when the placement platform 32 moves to the outside, the outer push switch 14 is pressed to discharge, so that the barrier door 25 opens under the action of the spring 252. At this time, the air column 12 expands, thereby causing the airbag column 215 to contract, realizing the separation of the second sleeve 214 from the second spline 212 and the fixation of the first sleeve 213 and the first spline 216. This further causes the barrier door 25 to open slowly under the action of the gear, making it convenient for the staff to remove the titanium alloy workpiece on the placement platform 32. This prevents the titanium alloy workpiece from being too far away from the opening of the box 1, which would affect the staff's ability to remove the titanium alloy workpiece.

[0047] Example 4: Unlike Example 3, as follows Figure 7 As shown, the placement platform 32 consists of several placement plates and a frame. Each placement plate includes several plates 321 with rotating shafts 320 at both ends. The rotating shafts pass through the frame and are connected to the first limiting block 322 on the frame. A threaded tube 332 passes through the mounting plate 331 and is fixedly connected to the second limiting block 323. The first limiting block 322 and the second limiting block 323 are connected by a first transmission belt. The rotating shafts are connected by a second transmission belt.

[0048] The working principle of this embodiment is basically the same as that of embodiment 3. The difference is that the reciprocating rotation of the threaded tube 332 can drive the reciprocating rotation of the plate 321, thereby removing the residual waste residue on the surface of the plate 321 and reducing the adhesion of the adhesive on the surface of the plate 321.

[0049] Example 5: Unlike Example 1, which is not shown in the figure, the barrier door 25 is provided with ball bearings on its side; specifically, the ball bearings are located at the bottom of the side of the barrier door and contact the inner wall of the opening, and the ball bearings are commercially available steel balls.

[0050] The working principle of this embodiment is basically the same as that of embodiment 1. The difference is that during the sliding process of the barrier door 25, the sliding friction is transformed into rolling friction under the action of the ball, thereby reducing the friction force and improving the efficiency and accuracy of the sliding of the barrier door 25.
