Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a milling and tapping fixture for an automotive cylinder bracket. Background Technology

[0002] Automotive hydraulic cylinders are an important component of automotive hydraulic systems, primarily used to realize various mechanical actions and power transmission. Automotive hydraulic cylinders typically consist of a cylinder body, piston, piston rod, and seals, and can convert hydraulic energy into mechanical energy to achieve linear reciprocating motion or oscillating motion.

[0003] Before the hydraulic cylinder bracket can be installed or welded with the hydraulic cylinder, it needs to be machined. When milling and tapping the hydraulic cylinder bracket, a fixture is needed to hold the bracket during the machining process. When using the existing fixture to hold the bracket, the hydraulic cylinder and the bracket need to be placed in the clamping cylinder one after the other, and then the clamping plates are used to hold the hydraulic cylinder and the bracket respectively. However, it was found in use that when the hydraulic cylinder and the bracket are placed one after the other, it is difficult to insert the hydraulic cylinder and the bracket into the clamping cylinder, which makes the operation inconvenient, time-consuming and labor-intensive, and needs to be improved. Utility Model Content

[0004] Based on the above description, this utility model provides a milling and tapping fixture for automotive cylinder brackets to solve the problem that existing milling and tapping fixtures for automotive cylinder brackets are inconvenient for inserting and placing the cylinder and bracket during use.

The clamping cylinders are provided with clamping mechanisms. The top surface of the worktable is provided with several fixing plates. Several slots are opened through the front and back of the fixing plates. The front of the fixing plates is provided with a concave frame. The clamping cylinders include a cylinder wall and a lower cylinder. The cylinder wall is placed on the top surface of the lower cylinder. The surface of the cylinder wall is provided with a protruding rod protruding into the slot. The end of the protruding rod away from the cylinder wall is provided with a baffle. The front of the baffle is rotatably connected to a T-shaped handle.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the slot is opened horizontally, the lower cylinder is placed on the top surface of the workbench, the surface of the lower cylinder is provided with a protruding rod II protruding into the slot, the end of the protruding rod II away from the lower cylinder is provided with a baffle II, and the front of the baffle II is rotatably connected with a T-shaped handle II.

[0008] Furthermore, a number of insertion holes are provided through the front and back of the fixing plate, and the back of both the first baffle and the second baffle are provided with insertion rods protruding into the insertion holes.

[0009] Furthermore, the end of the insertion rod away from either the first or second baffle is designed to be rounded.

[0010] Furthermore, both the first and second protruding rods are provided with baffles three on their surfaces, and a spring is provided between the front of the baffles three and the back of the fixing plate.

[0011] Furthermore, the front of the baffle three is provided with a protrusion, which is located inside the spring.

[0012] Furthermore, both clamping mechanisms include an upper arc-shaped clamping plate, a lower arc-shaped clamping plate, and a lead screw. The upper arc-shaped clamping plate and the lower arc-shaped clamping plate are both located inside the clamping cylinder. The lead screw is threaded to the outside of the cylinder wall, and one end of the lead screw is rotatably connected to the upper arc-shaped clamping plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0014] By setting a fixed plate on the workbench and configuring the clamping cylinder as the cylinder wall and the lower cylinder, and connecting the cylinder wall to the fixed plate using a protruding rod and a T-shaped handle, the position of the cylinder wall and the lower cylinder can be adjusted through the protruding rod and the T-shaped handle, so that the lower cylinder can be fully exposed to the outside.

However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0022] Example

[0023] Please refer to Figures 1-3 This embodiment provides a milling and tapping fixture for an automotive cylinder bracket, including a worktable 1 and two clamping cylinders 2. The clamping cylinders 2 are equipped with clamping mechanisms 3. Fixing plates 11 are provided on the top surface of the worktable 1, near the left and right sides of the front. Multiple slots 111 are formed between the front and back of the fixing plates 11. A concave frame 112 is provided on the front of each fixing plate 11. The clamping cylinders 2 include a cylinder wall 21 and a lower cylinder 22. The cylinder wall 21 is placed on the top surface of the lower cylinder 22. A protruding rod 4 protrudes into the slots 111 on the surface of the cylinder wall 21. A baffle 41 is provided at the end of the protruding rod 4 away from the cylinder wall 21. The back of the baffle 41 is flush with the fixing plate. The front surfaces of the 11 are in contact with each other. The front surface of the baffle 41 is rotatably connected to a T-shaped handle 5 that is close to the concave frame 112, so that part of the surface of the T-shaped handle 5 can be rotated to the inside of the concave frame 112, ensuring the stability of the position between the cylinder wall 21 and the lower cylinder 22. Both clamping mechanisms 3 include an upper arc-shaped clamping plate 31, a lower arc-shaped clamping plate 32 and a screw 33. The upper arc-shaped clamping plate 31 and the lower arc-shaped clamping plate 32 are both located inside the clamping cylinder 2. The lower arc-shaped clamping plate 32 is fixedly connected to the inside of the lower cylinder 22. The screw 33 is threaded to the outside of the cylinder wall 21, and one end of the screw 33 is rotatably connected to the upper arc-shaped clamping plate 31. The top of the screw 33 is provided with a handle.

[0024] In this embodiment, when clamping the cylinder bracket is required, the operator can simultaneously grasp both T-shaped handles 5 with both hands and rotate them, causing the T-shaped handles 5 to move away from the concave frame 112. Then, by continuing to grasp the T-shaped handles 5 and applying pressure backward, the operator uses the T-shaped handles 5 to move the baffle 41, the protruding rod 4, and the wall 21 of the clamping cylinder 2 backward simultaneously until the inner cavity of the lower cylinder 22 of the clamping cylinder 2 is completely exposed. The operator can then directly place the cylinder bracket to be milled onto the surface. On the arc surface of the lower arc-shaped clamping plate 32 inside the clamping cylinder 2, after it is placed and stabilized, the operator can grab the T-shaped handle 5 again and push it forward. The cylinder wall 21 directly drives the clamping mechanism 3 to move to the position above the cylinder bracket after placement, so that the cylinder wall 21 can achieve the reset operation between the lower cylinder 22 and the cylinder wall 21. Finally, the operator can apply pressure to rotate the lead screw 33, and the lead screw 33 drives the upper arc-shaped clamping plate 31 to move downward, thereby using the upper arc-shaped clamping plate 31 and the lower arc-shaped clamping plate 32 to achieve clamping and limiting of the cylinder bracket.

[0025] As an optional implementation, the slot 111 is opened in the horizontal direction, the lower cylinder 22 is placed on the top surface of the workbench 1, the surface of the lower cylinder 22 is provided with a protruding rod 6 protruding into the slot 111, the end of the protruding rod 6 away from the lower cylinder 22 is provided with a baffle 61, and the front of the baffle 61 is rotatably connected to a T-shaped handle 7, the T-shaped handle 7 and the concave frame 112 are close to each other.

[0026] In this embodiment, by grasping T-shaped handle 5 and T-shaped handle 7 and moving them to the left or back simultaneously, the positional distance between the two clamping cylinders 2 can be effectively adjusted, thereby making the clamp suitable for hydraulic cylinder brackets of different sizes.

[0027] As an optional implementation, a plurality of insertion holes 113 are provided through the front and back of the fixing plate 11. Both the back of the first baffle 41 and the second baffle 61 are provided with insertion rods 8 protruding into the insertion holes 113. The end of the insertion rod 8 away from the first baffle 41 or the second baffle 61 is designed to be rounded.

[0028] In this embodiment, after the clamping cylinder 2 is adjusted to a suitable position, the first baffle 41 and the second baffle 61 are pushed forward so that the insertion rod 8 can be inserted into the insertion hole 113 opened in the fixing plate 11, thereby achieving the limiting effect on the adjusted clamping cylinder 2, which is more conducive to the milling of the cylinder bracket.

[0029] As an optional implementation, both the first protrusion 4 and the second protrusion 6 are provided with a third baffle 9. A spring 10 is provided between the front of the third baffle 9 and the back of the fixing plate 11. The front of the third baffle 9 is provided with a protrusion 91, which is located inside the spring 10.

[0030] In this embodiment, after the reset operation between the cylinder wall 21 and the lower cylinder 22 is completed, the pressure applied to the baffle 39 by the spring 10 can ensure the stability between the cylinder wall 21 and the lower cylinder 22, which is more conducive to the operator rotating the lead screw 33.
