Description

Technical Field

[0001] This invention relates to the field of fixtures for machining the end face of universal joint forks, and particularly to a fixture for machining the end face of universal joint forks and its method of use. Background Technology

[0002] Clamps for machining the end faces of automotive universal joint forks are tools used to stabilize and fix the universal joint forks during machining. These clamps ensure that the workpiece (universal joint fork) maintains the correct position and angle during machining to achieve high-precision machining results. However, typical clamps can only provide simple limiting and fixing effects when holding the workpiece, and cannot be used to flip or adjust the height of the clamped workpiece according to the worker's needs. When machining intricate areas, workers need to bend over and lie down to observe closely, which can easily lead to back fatigue and increased labor burden. Furthermore, when machining different areas, the only way to switch between them is by disassembling and reassembling, reducing the applicability of the clamp. Therefore, optimization and improvement are needed. Summary of the Invention

[0003] The purpose of this invention is to solve the technical problems mentioned in the background section.

[0004] The present invention adopts the following technical solution: a fixture for machining the end face of a universal joint fork, comprising a worktable, an electric telescopic rod, and a clamping plate, wherein the output end of the electric telescopic rod is rotatably connected to the clamping plate, the worktable is provided with a lifting mechanism inside, and the clamping plate is provided with an adjustment mechanism on its side;

[0005] The lifting mechanism includes a lifting platform, an mounting block fixedly installed on the upper surface of the lifting platform, a lifting rod fixedly installed on the lower surface of the lifting platform, a mounting frame fixedly installed on the lower surface of the worktable, a lead screw rotatably connected inside the mounting frame, a guide rod fixedly installed inside the mounting frame, a connecting frame fixedly installed on the lower surface of the worktable, a motor fixedly installed on the surface of the connecting frame, a bevel gear A fixedly installed at the output end of the motor, and a bevel gear B fixedly installed at the bottom end of the lead screw.

[0006] The adjusting mechanism includes a fixed ring, which is fixedly connected to the output end of the electric telescopic rod. A limit block is fixedly installed on the side of the clamping plate. A limit rod is slidably connected inside the limit block. A push plate is fixedly installed at one end of the limit rod. A spring is fixedly installed on the side of the push plate.

[0007] Preferably, the lifting platform and lifting rod are slidably connected to the worktable, the lifting rod is threadedly connected to the lead screw, and the lifting rod is slidably connected to the guide rod. Here, the lead screw ensures stable lifting of the lifting platform.

[0008] Preferably, bevel gear A and bevel gear B mesh with each other, and the electric telescopic rod is fixedly connected to the mounting block. Here, the lead screw can be driven by a motor.

[0009] Preferably, the limiting rod and the fixing ring are slidably connected, and one end of the spring is fixedly connected to the limiting block. Here, the spring can drive the limiting rod to lock and limit the clamping plate.

[0010] Preferably, a cleaning mechanism is provided on the lower surface of the workbench. The cleaning mechanism includes a feeding bin, a feeding plate fixedly installed on the surface of the workbench, a feeding groove formed on the surface of the feeding plate, a rotating rod fixedly installed on one side of the bevel gear A, and a roller brush fixedly installed at one end of the rotating rod. Here, the cleaning mechanism can clean up the debris and waste generated during processing.

[0011] Preferably, the roller brush and rotating rod are rotatably connected to the feeding bin, and the feeding chute is connected to the feeding bin. Here, the roller brush can guide and discharge waste material.

[0012] Preferably, the surface of the feeding hopper is equipped with a dust collection mechanism, which includes a dust collection fan. An air outlet pipe is fixedly installed at the output end of the dust collection fan, and an air inlet pipe is fixedly installed at the input end of the dust collection fan. An air inlet plate is fixedly installed at one end of the air inlet pipe. A connecting block is fixedly installed on the upper surface of the feeding hopper, and a collection box is slidably connected inside the connecting block. A buckle is fixedly installed on the side of the connecting block, and a handle is fixedly installed on the side of the collection box. Here, the dust collection mechanism can easily suck out small metal fragments from the waste material.

[0013] Preferably, the air inlet plate is located inside the feeding hopper, and the air outlet pipe is connected to the connecting block. Here, the air inlet plate allows debris to be drawn into the collection box.

[0014] Preferably, the latch is rotatably connected to the collection box. Here, the latch can limit the position of the collection box.

[0015] A method for using a fixture for machining the end face of a universal joint fork includes the following steps:

[0016] S1: When it is necessary to clamp the workpiece, the workpiece can be placed between the clamping plates, and the clamping plates can clamp the workpiece by means of the electric telescopic rod;

[0017] S2: When the position of the workpiece needs to be adjusted, the motor can drive the bevel gear A to rotate. Through the meshing of bevel gear A and bevel gear B, the rotation of bevel gear A can drive bevel gear B and the lead screw to rotate in the position of the mounting bracket. The rotation of the lead screw causes the lifting rod to move the lifting platform upward, thereby adjusting the height of the workpiece. When the display surface of the workpiece needs to be adjusted, the clamping plate can be moved open by two sets of electric telescopic rods. Then, by grasping the push plate and pulling it, the push plate drives the limit rod to move, causing the limit rod to slide from the inside of the fixed ring to the inside of the limit block. Then, the clamping plate is grasped and rotated, causing the clamping plate to rotate at the output end of the electric telescopic rod, thereby flipping the workpiece. Afterward, the spring drives the push plate and the limit rod to move, causing the limit rod to slide from the inside of the limit block to the inside of the fixed ring, thereby fixing the clamping plate and the electric telescopic rod.

[0018] S3: When it is necessary to clean the waste generated during processing, the waste falls from the feeding plate to the feeding bin through the feeding chute. Then, the bevel gear A drives the rotating rod to rotate, which in turn drives the roller brush to rotate inside the feeding bin, so that the waste is automatically discharged from the feeding bin. When it is necessary to suck out the fine debris from the waste, the dust suction fan can suck the debris in from the air inlet plate and air inlet pipe, and then transport the debris to the inside of the connecting block through the air outlet pipe.

[0019] S4: When it is necessary to collect and clean metal shavings, you can grasp the buckle and rotate it to make the buckle rotate in the position of the collection box, and then grasp the handle and pull it to make the collection box slide out from the inside of the connecting block, thereby cleaning the shavings.

[0020] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0021] 1. In this invention, by setting up a lifting mechanism and an adjustment mechanism, the position of the workpiece can be adjusted smoothly. Adjusting the height avoids workers having to bend over and lie down to observe the details, which can easily lead to excessive back fatigue for workers during long working hours. By adjusting the workpiece flipping situation, the disassembly and reassembly steps are saved, and the workpiece can be rotated and flipped smoothly. In actual use, this improves the convenience of workpiece processing and also improves the applicability of the fixture.

[0022] 2. In this invention, by setting up a cleaning mechanism, the waste generated during processing can be automatically discharged and cleaned, avoiding the accumulation of waste at the bottom of the workpiece and reducing the impact of excessive waste accumulation on processing steps. Through automatic material discharge, the efficiency of workers in handling waste is improved in actual use, thereby improving the processing efficiency of the workpiece.

[0023] 3. In this invention, by setting up a dust collection mechanism, it is possible to suck out and collect small debris from waste materials, avoiding the inconvenience of workers handling small debris. In actual use, by automatically collecting small debris and sucking it out uniformly, the overall work efficiency is improved. Attached Figure Description

Example

[0038] Please see Figure 1-7 The lower surface of the workbench 1 is provided with a cleaning mechanism, which includes a feeding bin 19 for discharging waste.

A feeding groove 21 is opened on the surface of the feeding plate 20 to automatically discharge and clean the waste generated during processing. A rotating rod 22 is fixedly installed on one side of the bevel gear A17 to facilitate driving the roller brush 23 to rotate. A roller brush 23 is fixedly installed at one end of the rotating rod 22.

[0039] Please see Figure 1-7 The surface of the feeding bin 19 is equipped with a dust collection mechanism, which includes a dust collection fan 24 to suck out fine debris.

The buckle 30 is rotatably connected to the collection box 29 to lock and fix the collection box 29.

[0040] A method for using a fixture for machining the end face of a universal joint fork includes the following steps:

[0041] S1: When it is necessary to clamp the workpiece, the workpiece can be placed between the clamping plates 3, and the clamping plates 3 can clamp the workpiece by means of the electric telescopic rod 2.

[0042] S2: When the position of the workpiece needs to be adjusted, the motor 16 can drive the bevel gear A17 to rotate. Through the meshing of bevel gear A17 and bevel gear B18, the rotation of bevel gear A17 can drive bevel gear B18 and lead screw 13 to rotate at the position of mounting bracket 12. Thus, the rotation of lead screw 13 causes lifting rod 11 to drive lifting platform 9 to move upward, thereby adjusting the height of the workpiece. When the display surface of the workpiece needs to be adjusted, the clamping plate 3 can be moved open by the two sets of electric telescopic rods 2. Then, by grasping the push plate 7 and pulling it, the push plate 7 drives the limiting rod 6 to move, so that the limiting rod 6 slides from the inside of the fixed ring 4 to the inside of the limiting block 5. Then, the clamping plate 3 is grasped and rotated, so that the clamping plate 3 rotates at the output end of the electric telescopic rod 2, thereby flipping the workpiece. Then, the spring 8 drives the push plate 7 and the limiting rod 6 to move, so that the limiting rod 6 slides from the inside of the limiting block 5 to the inside of the fixed ring 4, thereby fixing the clamping plate 3 and the electric telescopic rod 2.

[0043] S3: When it is necessary to clean the waste generated during processing, the waste falls from the position of the feeding plate 20 and the feeding trough 21 to the position of the feeding bin 19. Then, the bevel gear A17 drives the rotating rod 22 to rotate, so that the rotating rod 22 drives the roller brush 23 to rotate inside the feeding bin 19, thereby automatically discharging the waste from the position of the feeding bin 19. When it is necessary to suck out the fine debris in the waste, the dust suction fan 24 can suck the debris from the position of the air inlet plate 27 and the air inlet pipe 26, and then transport the debris to the inside of the connecting block 28 through the position of the air outlet pipe 25.

[0044] S4: When it is necessary to collect and clean metal shavings, you can grasp the buckle 30 and rotate it so that the buckle 30 rotates in the position of the collection box 29, and then grasp the handle 31 and pull it to make the collection box 29 slide out from the inside of the connecting block 28, thereby cleaning the shavings.

[0045] Working Principle: First, when a workpiece needs to be clamped, it can be placed between clamping plates 3. The electric telescopic rod 2 can then clamp the workpiece. When the position of the workpiece needs to be adjusted, the motor 16 drives the bevel gear A17 to rotate. Through the meshing of bevel gear A17 and bevel gear B18, the rotation of bevel gear A17 drives bevel gear B18 and lead screw 13 to rotate at the position of mounting bracket 12. The rotation of lead screw 13 causes lifting rod 11 to move lifting platform 9 upward, thereby adjusting the height of the workpiece. When the display surface of the workpiece needs to be adjusted, the two sets of electric telescopic rods 2 can move clamping plates 3 apart. Then, by grasping and pulling push plate 7, push plate 7 moves limit rod 6, causing limit rod 6 to slide from inside fixed ring 4 to inside limit block 5. Then, clamping plates 3 are grasped and rotated, causing clamping plates 3 to rotate at the output end of electric telescopic rod 2, thereby flipping the workpiece. Finally, spring 8 drives the push plate 3 to rotate. The plate 7 moves with the limiting rod 6, causing the limiting rod 6 to slide from the inside of the limiting block 5 to the inside of the fixing ring 4, thereby fixing the clamping plate 3 and the electric telescopic rod 2. When it is necessary to clean the waste generated during processing, the waste falls from the position of the feeding plate 20 and the feeding trough 21 to the position of the feeding bin 19. Then, the bevel gear A17 drives the rotating rod 22 to rotate, causing the rotating rod 22 to drive the roller brush 23 to rotate inside the feeding bin 19, thereby automatically discharging the waste from the position of the feeding bin 19. When it is necessary to suck out small debris from the waste, the dust collector 24 can suck the debris into the air inlet plate 27 and air inlet pipe 26, and then transport the debris into the connecting block 28 through the air outlet pipe 25. When it is necessary to collect and clean metal debris, the buckle 30 can be grasped and rotated to rotate the buckle 30 in the collection box 29, and then the handle 31 can be grasped and pulled to slide the collection box 29 out of the connecting block 28, thereby cleaning the debris.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
