Description

Technical Field

[0001] This application belongs to the field of machining, specifically a fixture for round shaft workpieces. Background Technology

[0002] Circular shafts are typically shaft-type parts with a circular cross-section. They are an indispensable component of mechanical transmission systems, mainly used to transmit torque, bear loads, and support other rotating parts.

[0003] To ensure that the round shaft workpiece can be better connected and installed with other components, it is usually necessary to process the shaft end of the round workpiece, such as cutting it or making threaded grooves.

[0004] Currently, when machining round shaft workpieces, arc-shaped plates or V-shaped blocks are usually used to clamp their sides. However, when the shaft end of the round shaft workpiece is subjected to force during machining, it is easy to fall off the clamping position. Therefore, a round shaft workpiece fixture is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this application is to address the shortcomings of existing technologies by designing a round shaft workpiece clamp by setting up an installation block, a clamping block, a bolt, a limiting piece, a sliding rod, a limiting groove, a workpiece storage groove, a round shaft storage groove, a workpiece storage groove, and a round shaft storage groove, thereby solving the problem of unstable clamping when the shaft end of the round shaft workpiece is subjected to force.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A circular shaft workpiece clamping fixture includes a mounting block, a clamping block on the front side of the mounting block, the clamping block and the mounting block being connected by a connecting assembly, a workpiece storage groove 1 on the front side of the mounting block extending beyond the top of the workpiece storage groove 1, a circular shaft storage groove 1 on the inner wall of the mounting block below the workpiece storage groove 1, the workpiece storage groove 1 communicating with the circular shaft storage groove 1, a workpiece storage groove 2 on the rear side of the clamping block, both workpiece storage groove 1 and workpiece storage groove 2 being semi-cylindrical, and having the same diameter and height, the top of workpiece storage groove 2 extending beyond the clamping block, a circular shaft storage groove 2 on the inner wall of the clamping block below the workpiece storage groove 2, the workpiece storage groove 2 communicating with the circular shaft storage groove 2, both circular shaft storage groove 1 and circular shaft storage groove 2 being semi-cylindrical, and having the same diameter and height, a limit assembly being provided inside the mounting block and on the rear side of the clamping block.

[0008] Preferably, the connecting assembly includes a bolt, the outer wall of which is threadedly connected to the inner wall of the mounting block, and the outer wall of the bolt penetrates through and is rotatably connected to the inner wall of the clamping block.

[0009] Preferably, the limiting component includes a limiting groove, which is formed on the inner wall of the mounting block. A limiting piece is slidably connected to the inner wall of the limiting groove. A sliding rod is fixedly connected to the front surface of the limiting piece, and the front end of the sliding rod is fixedly connected to the rear surface of the clamping block.

[0010] Preferably, the mounting block is provided with a guide rail on its exterior, and the guide rail is connected to the mounting block by a fixing component.

[0011] Preferably, the fixing component includes a second bolt, the outer wall of the second bolt being through and rotatably connected to the inner wall of the mounting block, and the inner wall of the guide rail having a threaded groove that matches the second bolt.

[0012] Preferably, the projection shape of the mounting block on its right surface is I-shaped, and the front protrusion of the mounting block is located on the outside of the guide rail.

[0015] 1.

[0024] Reference Figure 2 , Figure 4 and Figure 5 A circular shaft workpiece clamp includes a mounting block 1, the projection shape of which on its lower surface is convex. A clamping block 2 is provided on the front side of the mounting block 1, the width of which is the same as the width of the convex front part of the mounting block 1. A workpiece storage groove 4 is formed on the front side of the mounting block 1, the top end of which extends outside the mounting block 1. A circular shaft storage groove 5 is formed on the inner wall of the mounting block 1 below the workpiece storage groove 4, and the workpiece storage groove 4 and the circular shaft storage groove 5 are connected. A workpiece storage groove 6 is formed on the rear side of the clamping block 2, the top end of which extends outside the clamping block 2. Both the workpiece storage groove 4 and the workpiece storage groove 6 are semi-cylindrical, and the workpiece storage groove 4 and the workpiece storage groove 6 are connected. The diameter and height of the workpiece storage groove 2 6 are the same. When the workpiece storage groove 1 4 and the workpiece storage groove 2 6 are in contact with the front surface of the mounting block 1 and the rear surface of the clamping block 2, they together form a cylindrical groove with a diameter that matches the diameter of the workpiece. The inner wall of the clamping block 2 located below the workpiece storage groove 2 6 is provided with a circular shaft storage groove 2 7. The workpiece storage groove 2 6 and the circular shaft storage groove 2 7 are connected. The circular shaft storage groove 1 5 and the circular shaft storage groove 2 7 are both semi-cylindrical, and the diameter and height of the circular shaft storage groove 1 5 and the circular shaft storage groove 2 7 are the same. When the circular shaft storage groove 1 5 and the circular shaft storage groove 2 7 are in contact with the front surface of the mounting block 1 and the rear surface of the clamping block 2, they together form a cylindrical groove with a diameter that matches the shaft diameter of the workpiece.

[0025] As a preferred method, refer to Figure 2 , Figure 4 and Figure 5 The clamping block 2 and the mounting block 1 are connected by a connecting component 3. The connecting component 3 includes a bolt 31. The outer wall of the bolt 31 is threadedly connected to the inner wall of the mounting block 1. The outer wall of the bolt 31 passes through and is rotatably connected to the inner wall of the clamping block 2. A threaded hole with a shape that matches the shape of the bolt 31 is opened on the front side of the clamping block 2. The projection of the bolt 31 on the rear surface of the mounting block 1 coincides with the projection of the threaded hole on the rear surface of the mounting block 1.

[0026] As a preferred method, refer to Figures 4-6 A limiting component 8 is provided inside the mounting block 1 and on the rear side of the clamping block 2. The limiting component 8 includes a limiting groove 81, with an annular protrusion at the front end of the limiting groove 81. The limiting groove 81 is formed on the inner wall of the mounting block 1. A limiting piece 82 is slidably connected to the inner wall of the limiting groove 81. The diameter of the limiting piece 82 matches the diameter of the limiting groove 81. The diameter of the limiting piece 82 is larger than the diameter of the protrusion at the front end of the limiting groove 81. The protrusion ensures that the movable range of the limiting piece 82 is limited. A sliding rod 83 is fixedly connected to the front surface of the limiting piece 82. The front end of the sliding rod 83 is fixedly connected to the rear surface of the clamping block 2. The movable range of the limiting piece 82 is less than the difference in diameter between the workpiece storage groove 4 and the shaft storage groove 5.

[0027] As a preferred method, refer to Figure 1 and Figure 2 The mounting block 1 is provided with a guide rail 9 on its outside. The projection shape of the mounting block 1 on its right surface is I-shaped. The front protrusion of the mounting block 1 is located on the outside of the guide rail 9. The inner wall of the guide rail 9 is provided with a groove for the mounting block 1 to move. The front height of the groove is lower than the rear height. The height of the rear protrusion of the mounting block 1 matches the rear height of the groove of the guide rail 9. The width of the rear protrusion of the mounting block 1 is narrower than the width of the rear groove of the guide rail 9.

[0028] As a preferred method, refer to Figure 1 , Figure 2 and Figure 4 The guide rail 9 is connected to the mounting block 1 by a fixing component 10. The fixing component 10 includes a bolt 2 101. The outer wall of the bolt 2 101 passes through and is rotatably connected to the inner wall of the mounting block 1. The inner wall of the guide rail 9 is provided with a threaded groove 102. The number of threaded grooves 102 is set to multiple, and the multiple threaded grooves 102 are arranged in a linear array in the left and right directions. The threaded grooves 102 match the bolt 2 101.

[0029] As a preferred method, refer to Figures 2-5 The front surface of the guide rail 9 is fixedly connected to a limiting tooth 11. The top view of the limiting tooth 11 is a plurality of isosceles triangles arranged in a linear array in the left and right directions, and the base points of each pair of adjacent triangles are in contact with each other. The rear surface of the mounting block 1 located on the outer side of the guide rail 9 is provided with a limiting groove 12. The limiting groove 12 fits the shape of the limiting tooth 11. By setting the limiting tooth 11 and the limiting groove 12, it is ensured that when the mounting block 1 is relatively fixed to the guide rail 9, if the mounting block 1 is subjected to a force that moves in the left and right directions, in addition to the bolt 101, there is also the resistance generated by the contact between the outer wall of the limiting tooth 11 and the limiting groove 12, so as to better generate resistance to the force in that direction.

[0030] When using the equipment, if it is necessary to fix the round shaft workpiece, the operator first rotates bolt 31, so that bolt 31 moves forward relative to mounting block 1 while rotating.

[0031] Since the inner wall of the mounting block 1 has a threaded hole that fits with the bolt 31, when the bolt 31 rotates in the threaded hole, it can also generate displacement in the front and back directions in addition to rotation.

[0032] Since bolt 31 is rotatably connected to clamping block 2, when bolt 31 moves in the front-back direction, it can drive clamping block 2 to move synchronously with it. Therefore, clamping block 2 moves forward with bolt 31.

[0033] Since the clamping block 2 is fixed to the slide rod 83, the clamping block 2 also drives the slide rod 83 to move forward during its forward movement. The slide rod 83 is fixed to the limiting piece 82. Since the limiting piece 82 slides relative to the limiting groove 81, the clamping block 2 can only slide back and forth relative to the limiting groove 81. Therefore, the clamping block 2 can only slide back and forth relative to the mounting block 1. Thus, the bolt 31 can only drive the clamping block 2 to move back and forth, but cannot make the clamping block 2 rotate synchronously with it as it rotates. Therefore, the clamping block 2 can move back and forth while keeping the upper surface of the workpiece storage groove 6 horizontal.

[0034] When there is a distance between clamping block 2 and mounting block 1, there is an extra gap between workpiece storage slot 1 4 and workpiece storage slot 2 6, and there is an extra gap between round shaft storage slot 1 5 and round shaft storage slot 2 7. Therefore, the operator can easily place the round shaft workpiece in the slot, so that the lower surface of the workpiece is on the upper surface of workpiece storage slot 1 4 and workpiece storage slot 2 6, and the round shaft of the workpiece is located between round shaft storage slot 1 5 and round shaft storage slot 2 7.

[0035] Since the movable range of the limiting piece 82 is less than the diameter difference between the workpiece storage groove 4 and the shaft storage groove 5, the workpiece will not fall off.

[0036] Subsequently, the staff rotated bolt 31 in the opposite direction to the previous rotation of bolt 31. As a result, bolt 31 moved backward while rotating, which in turn moved clamping block 2 backward, so that the round shaft workpiece located between workpiece storage slot 4 and workpiece storage slot 6 could be clamped by mounting block 1 and clamping block 2.

[0037] After the workpiece is fixed, when it is necessary to adjust the position of the mounting block 1 and the workpiece as a whole, the worker first rotates bolt 101, so that bolt 101 moves forward relative to the guide rail 9 during the rotation.

[0038] When bolt 101 rotates to leave the threaded groove 102, the relative fixed state between mounting block 1 and guide rail 9 is released. However, because the height of the rear end protrusion of mounting block 1 matches the height of the rear groove of guide rail 9, mounting block 1 can move relative to guide rail 9 in the front-back and left-right directions, but cannot be offset in other directions.

[0039] At this time, the staff moves the installation block 1 forward so that the limiting groove 12 does not contact the limiting tooth 11, and then adjusts the horizontal position of the installation block 1.

[0040] After the adjustment is completed, the staff first pushes the mounting block 1 backward, then rotates the bolt 101. When the bolt 101 enters the new threaded groove 102, the mounting block 1 is fixed to the guide rail 9 again.

[0041] After bolt 2 101 is fixed, a new limiting tooth 11 enters the limiting groove 12. Therefore, during the use of the equipment, the limiting tooth 11 can maintain a state of contact with the limiting groove 12.
