Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and in particular to a high-efficiency tapping fixture for rod end spherical bearings. Background Technology

[0002] A rod end spherical plain bearing is a spherical plain bearing with or mounted on a rod end. It belongs to a subcategory of spherical plain bearings. Spherical plain bearings are spherical sliding bearings. A Chinese utility model patent, authorized publication number "CN219766992U", discloses a tapping fixture for rod end spherical plain bearings, including a support plate, a fixed plate fixedly connected to the upper end of the support plate, and a mandrel mounted on the right end of the fixed plate. A positioning block is fixedly connected to the left end of the mandrel. A positioning groove is opened on the right end of the fixed plate, and the positioning block is slidably connected to the inner side of the positioning groove. A locking screw is threadedly connected to the front end of the fixed plate, and the locking screw contacts the positioning block. A first screw is rotatably connected to the upper end of the fixed plate, and a first V-block is threadedly connected to the outer side of the first screw. A movable plate is slidably connected to the upper end of the support plate on the right end of the fixed plate. A cylinder is fixedly connected to the right end of the movable plate, and the cylinder is fixedly connected to the upper end of the support plate. An installation block is fixedly connected to the left end of the movable plate, and a second screw is rotatably connected to the upper end of the installation block. A second V-block is threadedly connected to the outer side of the second screw. The mandrel can be replaced, enabling the processing of rod end spherical plain bearings of different sizes.

[0003] The above technical solution uses a first V-block for positioning, a cylinder to move a moving plate to the left, and the moving plate to move a second V-block to the left to fix the rod end joint bearing, thus enabling tapping of the rod end joint bearing. The structure is simple and the operation is convenient. However, the above technical solution still has certain drawbacks. For example, while the device uses a cylinder to move a moving plate to the left, which in turn moves a second V-block to the left to fix the rod end joint bearing, the V-shaped clamping block requires maintenance and repair after prolonged use. This requires workers to use special tools to disassemble the entire clamping assembly before disassembling the V-shaped clamping block, which is cumbersome and difficult, reducing the efficiency of V-shaped clamping block maintenance and repair while increasing the workload of workers. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a high-efficiency tapping fixture for rod end joint bearings. It can solve the problem that the equipment uses a cylinder to drive a moving plate to the left, and the moving plate drives the second V-block to the left to fix the rod end joint bearing. However, the V-shaped clamping block requires maintenance and repair after long-term use. It requires workers to use special tools to disassemble the entire clamping assembly and then disassemble the V-shaped clamping block. This operation is complicated and difficult, which reduces the efficiency of maintenance and repair of the V-shaped clamping block and increases the workload of workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency tapping fixture for rod end joint bearings, comprising a worktable and two fixed seats, wherein two limiting devices are provided on the worktable;

[0006] The limiting device includes a mounting block, a clamping block, and two protective shells. The two protective shells are fixedly connected to each other on both sides of the clamping block. A sliding mounting seat groove is provided on one outer wall of the mounting block, and a sliding mounting seat is fixedly connected to one outer wall of the clamping block. The outer wall of the sliding mounting seat is slidably connected to the inside of the sliding mounting seat groove.

[0007] The outer walls of both protective shells are slidably connected with rotating threaded rods, the inner walls of both sides of the sliding mounting seat groove are provided with first limiting block grooves, the interiors of the two first limiting block grooves are slidably connected with limiting blocks, and the outer walls of both sides of the sliding mounting seat are provided with second limiting block grooves.

[0008] Preferably, the outer walls of the four conical blocks on the sliding mounting base are slidably connected to the interiors of the four conical grooves of the sliding mounting base groove, and the interiors of the two protective shells are respectively connected to the interiors of the corresponding first limiting block grooves;

[0009] The two rotating threaded rods extend threadedly into the first limit block groove at one end near the limit block and are rotatably connected to one end of the corresponding limit block. The two limit blocks extend slidably into the sliding mounting seat groove at one end near the second limit block groove and are in contact with the inner wall of the corresponding second limit block groove.

[0010] Preferably, the upper surface of the worktable has two conical grooves, and the outer walls of the two conical blocks at the lower end of the front fixing seat are slidably connected to the interior of the corresponding conical grooves.

[0011] The first cylinder is mounted on the upper surface of the workbench. The output end of the first cylinder is fixedly connected to the outer wall of one side of the front fixed seat, and the rear fixed seat is fixedly connected to the upper surface of the workbench at the end away from the first cylinder.

[0012] Preferably, a second cylinder is fixedly connected to the upper surface of both of the fixed seats, and a mandrel is slidably connected to the groove on the lower outer wall of the rear fixed seat near the first cylinder.

[0013] The mandrel has a fixing bolt groove on the outer wall near the rear end of the fixing seat, and a fixing bolt is connected to the groove with internal threads on the outer wall of the rear end of the fixing seat.

[0014] Preferably, the threaded end of the fixing bolt near the fixing bolt groove extends into the groove on the lower outer wall of the rear fixing seat near the first cylinder and is connected to the internal thread of the fixing bolt groove.

[0015] Both of the mounting bases have a "U" shape at the top.

[0016] Preferably, the output ends of the two second cylinders slide into the interior of the corresponding fixed seats and are respectively fixedly connected to the upper surface of the corresponding mounting blocks;

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This rod end spherical bearing uses a high-efficiency tapping chuck. By turning the threaded rod in the limiting device, it rotates and moves in the opposite direction, which in turn drives the limiting block to move in the opposite direction. Then, by moving the limiting block in the opposite direction, the outer wall of its other end disengages from the inner wall of the second limiting block groove. Then, by pulling the clamping block, the clamping block can be removed from the mounting block. This makes the removal of the clamping block simple and quick, avoiding the need for workers to disassemble the entire clamping assembly to remove the clamping block. This effectively reduces the workload of workers and improves the maintenance and repair efficiency of the clamping block. Attached Figure Description

[0032] The limiting device includes a mounting block 6, a clamping block 5, and two protective shells 4. The two protective shells 4 are fixedly connected to each other on both sides of the clamping block 5. A sliding mounting seat groove 13 is formed on one outer wall of the mounting block 6. A sliding mounting seat 14 is fixedly connected to one outer wall of the clamping block 5. The outer wall of the sliding mounting seat 14 is slidably connected to the inside of the sliding mounting seat groove 13. Rotating threaded rods 11 are slidably connected to the outer walls of both protective shells 4. The outer walls of the four conical blocks on the sliding mounting seat 14 are slidably connected to the inside of the four conical grooves of the sliding mounting seat groove 13. A first limiting device is formed on the inner walls of both sides of the sliding mounting seat groove 13. The two first limiting block grooves 15 are slidably connected to the interior of each limiting block 17. The interiors of the two protective shells 4 are respectively connected to the interiors of the corresponding first limiting block grooves 15. The ends of the two rotating threaded rods 11 near the limiting block 17 are threaded into the interior of the first limiting block grooves 15 and are respectively rotatably connected to the ends of the corresponding limiting blocks 17. The outer walls on both sides of the sliding mounting seat 14 are provided with second limiting block grooves 16. The ends of the two limiting blocks 17 near the second limiting block grooves 16 are slidably extended into the interior of the sliding mounting seat groove 13 and respectively contact the inner wall of the corresponding second limiting block groove 16.

[0033] The workbench 1 has two conical grooves 3 on its upper surface. The outer walls of the two conical blocks at the lower end of the front fixing seat 9 are slidably connected to the interior of the corresponding conical grooves 3. A first cylinder 2 is installed on the upper surface of the workbench 1. The output end of the first cylinder 2 is fixedly connected to the outer wall of one side of the front fixing seat 9. The rear fixing seat 9 is fixedly connected to the upper surface of the workbench 1 at the end away from the first cylinder 2. A second cylinder 7 is fixedly connected to the upper surface of both fixing seats 9. A mandrel 12 is slidably connected to the groove at the lower end of the outer wall of the rear fixing seat 9 near the first cylinder 2.

Two slide rods 8 are slidably connected to the upper surface of the two fixing seats 9. The ends of the four slide rods 8 near the mounting block 6 slide to the interior of the fixing seat 9 and are fixedly connected to the upper surface of the corresponding mounting block 6 respectively.

[0034] Furthermore, when using this device, it is started by connecting an external power source. The rod end joint bearing is placed in a suitable position. The appropriate mandrel 12 is installed on the rear end fixing seat 9 by fixing bolts 10 according to the rod end joint bearing. Then, the rod end joint bearing is initially positioned by fitting the lower end of the rod end joint bearing onto the outer wall of the mandrel 12. Then, the output end of the second cylinder 7 moves downward, driving the mounting block 6 downward and simultaneously driving the clamping block 5 downward. In this way, the clamping block 5 is adjusted to a suitable height according to the rod end joint bearing by moving downward. Then, the output end of the first cylinder 2 drives the front end fixing seat 9 closer to the rear end fixing seat 9, while simultaneously driving the clamping block 5 to clamp and fix the rod end joint bearing. Then, the rod end joint bearing can be tapped. When it is necessary to remove the clamping block 5, the threaded rod 11 is turned and rotated to move in the opposite direction, while simultaneously driving the limiting block 17 to move in the opposite direction. Then, the outer wall of the other end of the limiting block 17 is disengaged from the inner wall of the second limiting block groove 16 by moving in the opposite direction. Then, the clamping block 5 can be removed from the mounting block 6 by pulling it.

[0035] By rotating the threaded rod 11 in the limiting device, the limiting block 17 moves in the opposite direction. Then, the outer wall of the other end of the limiting block 17 disengages from the inner wall of the second limiting block groove 16. Then, the clamping block 5 can be removed from the mounting block 6 by pulling it. This method of disassembling the clamping block 5 is simple and quick, avoiding the need for workers to disassemble the entire clamping assembly to remove the clamping block 5. This effectively reduces the workload of workers and improves the maintenance and repair efficiency of the clamping block 5.
