Description

Technical Field

[0001] This utility model relates to the field of gear shaft machining technology, specifically to a positioning fixture for machining the side of a gear shaft. Background Technology

[0002] During the machining of gear shafts, it is often necessary to ream or drill holes on the side of the shaft to assemble locating pins or other connecting components.

[0003] Existing methods for machining the sides of gear shafts typically employ single-piece positioning and clamping. For example, Chinese patent "CN221435699U" discloses a "gear shaft machining fixture," which uses clamping components to fix a single gear shaft. While this device can clamp gear shafts of different diameters, this machining method is inefficient in mass production, requiring multiple clamping and disassembly operations, which is time-consuming and labor-intensive. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning fixture for machining the side of a gear shaft, so as to solve the problem that the existing technology of fixing a gear shaft by using a fixture is time-consuming and labor-intensive.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A positioning fixture for machining the side of a gear shaft, used for mounting the gear shaft body, comprising: Base plate; Two sets of support members are respectively located on both sides of the base plate. Each set of support members includes at least two support seats for supporting the gear shaft body. The fixing assembly includes a fixing frame disposed on the base plate, two fixing members slidably disposed on the fixing frame along a first direction and corresponding to the support base, two movable members slidably disposed on the fixing frame along a second direction, and a driving member. The two movable members respectively abut against the two fixing members, so that the driving member drives the two movable members to slide in opposite directions along the second direction, so that the fixing members slide along the first direction and abut against the gear shaft body, thereby fixing the gear shaft body on the support base. Wherein, the first direction is perpendicular to the second direction.

[0006] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up the fixed components, the driving component drives the two movable components to slide in opposite directions within the fixed frame along the second direction, so that the movable components gradually squeeze the corresponding fixed components, and the fixed components move within the fixed frame along the first direction and gradually abut against the corresponding gear shaft body, thus completing the fixation of the two gear shaft bodies. This achieves the simultaneous fixation of two gear shaft bodies, reduces the number of clamping operations, and thus improves work efficiency and saves manpower.

[0007] Furthermore, both of the support seats are provided with mounting slots, and the gear shaft body is mounted between the two mounting slots.

[0008] Furthermore, the fixing member includes a connecting frame that is slidably disposed on the fixing frame along a first direction, and an extrusion cone block and a fixing seat respectively disposed at both ends of the connecting frame. The movable member includes a connecting plate that is slidably disposed on the fixing frame along a second direction and a pushing cone block disposed on the connecting plate. The large end of the pushing cone block is connected to the connecting plate. The pushing cone block penetrates into the fixing frame and abuts against the conical surface of the extrusion cone block.

[0009] Furthermore, there are two fixing seats, which are located on both sides of the connecting frame, and each has a fixing groove.

[0010] Furthermore, both the mounting groove and the fixing groove have a V-shaped structure.

[0011] Furthermore, the driving component includes a bidirectional screw, the fixing frame is provided with a mounting base, the mounting base rotatably mounts the bidirectional screw, and the two ends of the bidirectional screw are respectively threadedly connected to the two connecting plates.

[0012] Furthermore, an adjustment knob is provided at the end of the bidirectional screw.

[0018] like Figure 1-3As shown in the figure, this utility model embodiment proposes a positioning fixture for machining the side of a gear shaft, used to install a gear shaft body 10, including: a base plate 20; two sets of support members, respectively disposed on both sides of the base plate 20, each set of support members including at least two support seats 30 for supporting the gear shaft body 10; a fixing assembly including a fixing frame 40 disposed on the base plate 20, two fixing members 50 slidably disposed on the fixing frame 40 along a first direction and corresponding to the support seats 30, two movable members 60 slidably disposed on the fixing frame 40 along a second direction, and a driving member, wherein the two movable members 60 respectively abut against the two fixing members 50, so that the driving member drives the two movable members 60 to slide in opposite directions along the second direction, so that the fixing members 50 slide along the first direction and abut against the gear shaft body 10, thereby fixing the gear shaft body 10 on the support seats 30; wherein, the first direction is perpendicular to the second direction.

[0019] In this embodiment of the invention, during use, the operator places two gear shaft bodies 10 to be processed on the support seats 30 on both sides of the base plate 20 to support the gear shaft bodies 10. Then, the driving component drives two movable parts 60 to slide back and forth in the second direction within the fixed frame 40, so that the movable parts 60 gradually press against the corresponding fixed parts 50, causing the fixed parts 50 to move in the first direction within the fixed frame 40 and gradually abut against the corresponding gear shaft bodies 10. At the same time, in conjunction with the support seats 30, the two gear shaft bodies 10 are fixed, ensuring that they will not move during processing. This achieves the goal of fixing the two gear shaft bodies 10 in one clamping, which not only reduces the number of clamping operations but also improves work efficiency and saves manpower. Furthermore, both support seats 30 are provided with mounting slots, and the gear shaft bodies 10 are mounted between the two mounting slots. The mounting slots have a V-shaped structure, which not only serves as initial positioning but also ensures a certain degree of stability.

[0020] Specifically, such as Figure 2-3As shown, in this embodiment of the present invention, the fixing member 50 includes a connecting frame 51 slidably disposed on the fixing frame 40 along a first direction, and a pressing cone 52 and a fixing seat 53 respectively disposed at both ends of the connecting frame 51. The movable member 60 includes a connecting plate 61 slidably disposed on the fixing frame 40 along a second direction and a pushing cone 62 disposed on the connecting plate 61. The large end of the pushing cone 62 is connected to the connecting plate 61. The pushing cone 62 penetrates into the fixing frame 40 and abuts against the conical surface of the pressing cone 52. Specifically, when the fixing member 50 is adjusted by the movable member 60, the two connecting plates 61 are pushed by the driving member, causing the corresponding pushing cones 62 to move in opposite directions within the fixing frame 40 along the second direction. Since the inclined surface of the pushing cone 62 is always in contact with the inclined surface of the pressing cone 52 on the connecting frame 51, the movement of the pushing cone 62 is decomposed into a force under the action of the inclined surface. This force forces the pressing cone 52 together with the connecting frame 51 to move in the first direction, so that the fixed seat 53 on the connecting frame 51 moves towards the gear shaft body 10 on the corresponding support seat 30 until the two gear shaft bodies 10 are pressed onto the corresponding support seat 30, thus completing the fixation of the gear shaft bodies 10.

[0021] Furthermore, two fixing seats 53 are provided, located on both sides of the connecting frame 51, and each has a fixing groove. The fixing groove has a V-shaped structure, which makes the fixing seat 53 form a surface contact with the outer circle of the gear shaft body 10 with good containment. This not only increases the contact area and prevents damage to the workpiece, but also, in conjunction with the mounting groove on the support seat 30, realizes automatic centering and positioning of the gear shaft body 10, effectively preventing axial movement and circumferential rotation during the processing, thereby improving the stability of the processing.

[0022] Specifically, such as Figure 2-3 As shown in this embodiment of the invention, the driving component includes a bidirectional screw 70, and the fixing frame 40 is provided with a mounting base 41. The mounting base 41 rotatably mounts the bidirectional screw 70, and both ends of the bidirectional screw 70 are threadedly connected to the two connecting plates 61 respectively. Specifically, when the driving component drives the two connecting plates 61 to move, rotating the bidirectional screw 70 causes the connecting plates 61 at both ends to move away from each other, thereby driving the corresponding pushing cone 62 to move, and indirectly driving the fixing base 53 to move, so as to abut against the corresponding gear shaft body 10, thus completing the fixing of the gear shaft body 10. When unfixing, simply reverse the bidirectional screw 70 to bring the two connecting plates 61 closer together. Moreover, the end of the bidirectional screw 70 is provided with an adjustment knob 71, which can be easily adjusted manually.

[0023] Secondly, the fixing frame 40 is provided with a mounting groove, and a spring piece 80 is provided in the mounting groove. The spring piece 80 abuts against the pressing cone 52. Specifically, when the two pressing cones 52 move in the first direction to fix the gear shaft body 10, the pressing cones 52 press the corresponding spring piece 80, causing the spring piece 80 to deform. When disassembling the gear shaft body 10, by reversing the bidirectional screw 70, the two connecting plates 61 drive their corresponding pushing cones 62 to move towards each other, so that the corresponding pressing cones 52 can move in the opposite direction in the first direction under the action of the spring piece 80, thereby releasing the fixation of the gear shaft body 10 for subsequent reuse.

[0024] It should be understood that the two connecting plates 61 are respectively threaded onto the threaded sections at both ends of the bidirectional screw 70. Since the threaded sections at both ends of the bidirectional screw 70 are in opposite directions, when the bidirectional screw 70 is rotated, the two connecting plates 61 move towards or away from each other at both ends of the bidirectional screw 70, thereby fixing or releasing the gear shaft body 10.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
