Description

Technical Field

[0001] This utility model relates to the field of machine tool fixture technology, specifically a vise fixture for machining machine tool parts. Background Technology

[0002] A vise is a mechanical device used to clamp workpieces. It is widely used in machining, woodworking, metal processing and other fields. It fixes the workpiece by adjusting the jaws, ensuring stability and accuracy during the processing.

[0003] In the prior art, Chinese patent application number CN202011152631.7 discloses a high-precision miniature vise for machine tool accessories. A locking block is fixedly connected to the middle position of the upper surface of the support plate, and connection holes are opened at the front ends of both sides of the support plate. A sealing plate is slidably connected inside the connection hole. An iron core is provided on one side of the sealing plate. An inner cavity is opened inside the support plate, and an installation block is installed in the middle position inside the support plate. A one-way valve is fixedly connected to the front surface of the installation block to increase the cooling effect on the moving block. When clamping an object, the contact surface between the object and the vise is cooled. Combined with the spraying of coolant, the cooling effect can be better, improving the safety of processing.

[0004] Based on the above information, it can be seen that existing vises generally use the rotation of a lead screw to move the clamping block, thereby achieving the purpose of clamping the workpiece. However, in actual use, different workpiece materials require different clamping surfaces. Furthermore, the clamping mechanism of existing vises is generally an integrated structure, which is not convenient for replacement and adjustment. Utility Model Content

[0005] The purpose of this utility model is to provide a vise fixture for machining machine tool parts, so as to solve the problem mentioned in the background art that it is inconvenient to change and adjust the clamping surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vise clamp for machining machine tool parts, comprising a fixed base fixedly mounted on a machining platform, a mounting block fixedly connected to the fixed base by bolts, two symmetrical clamping blocks arranged inside the fixed base, and a transmission screw installed in the internal thread of the clamping blocks, the transmission screw being rotatably connected to a fixed frame, the fixed frame and the mounting blocks forming a disassembly and installation structure; a clamping pad is installed above the clamping blocks, and the clamping pad and the clamping blocks forming a detachable and replaceable structure.

[0007] Preferably, the fixing frame utilizes the first bolts passing through its left and right ends to form a threaded disassembly and assembly structure with the mounting block.

[0008] Preferably, a limiting groove is provided on the inner side of the mounting block, and limiting sliders are fixedly installed on the left and right sides of the clamping block to slide in cooperation with the limiting groove.

[0009] Preferably, the upper end of the clamping block has an installation groove that mates with the clamping pad, and a second bolt that is threadedly fitted into the installation groove is installed through the inside of the clamping pad.

[0010] Preferably, the clamping block has an internal receiving groove, and an absorbent sponge is installed inside the receiving groove.

[0011] Preferably, the absorbent sponge absorbs liquid lubricating oil inside, and a protective cover is installed on top of the absorbent sponge, and the protective cover and the receiving groove form an up-and-down sliding structure.

[0012] Preferably, the clamping block has a discharge hole inside that corresponds to the position of the transmission screw, and the discharge hole is connected to the receiving groove through a connecting groove inside the clamping block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This vise fixture for machining machine tool parts adopts a novel structural design, the specific details of which are as follows:

[0014] 1. The transmission screw and the clamping block are connected by a fixed frame and an mounting block. The fixed frame is installed between the mounting block and the first bolt, so that the two can be disassembled for easy internal maintenance and cleaning of internal debris. At the same time, the clamping pad is installed between the mounting groove and the second bolt, and can also be disassembled to facilitate the replacement of clamping pads of different materials according to different workpieces.

[0015] Furthermore, by rotating the lead screw, the clamping blocks are moved to achieve the clamping operation of the workpiece. In this process, the transmission lead screw is set with two opposite thread structures, which can drive the two clamping blocks to move synchronously and automatically center the workpiece. Compared with the traditional reverse moving clamping, it has higher processing accuracy.

[0016] 2. An accommodating groove is opened inside the clamping block, and an absorbent sponge is placed inside the accommodating groove. The water-absorbing sponge's water-retaining capacity is used to absorb liquid lubricating oil, while a protective cover is used to reduce the evaporation of lubricating oil.

[0017] Furthermore, when lubrication is needed, the staff uses tools (such as tweezers) to press down on the protective cover, causing the cover to squeeze the absorbent sponge. At this time, the lubricating oil in the absorbent sponge is discharged from the discharge hole through the connecting groove and finally falls onto the transmission screw, achieving the purpose of timely lubrication.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-3 To facilitate disassembly and replacement, this embodiment provides the following technical solution, specifically: a fixed base 1 is fixedly installed on the processing platform; a mounting block 2 is fixedly connected to the fixed base 1 using bolts; two symmetrical clamping blocks 3 are provided on the inner side of the fixed base 1; a transmission screw 4 is installed inside the clamping block 3 with internal threads; the transmission screw 4 is rotatably connected to the fixed frame 5; the fixed frame 5 and the mounting block 2 form a disassembly and installation structure; a clamping pad 9 is installed above the clamping block 3; the clamping pad 9 and the clamping block 3 form a disassembly and replacement structure; the fixed frame 5 uses first bolts 6 passing through its left and right ends to form a threaded disassembly and installation structure with the mounting block 2; an installation groove 10 is opened at the upper end of the clamping block 3 to cooperate with the clamping pad 9; and a second bolt 11 that is threadedly engaged with the installation groove 10 is installed inside the clamping pad 9.

[0027] When using the device, first, fix the base 1 on the processing platform. Then, use bolts to fix the mounting block 2 on top of the base 1. Next, insert the clamping block 3 through the outside of the transmission screw 4. Then, use the first bolt 6 to fix the fixing frame 5 in the middle of the inner side of the mounting block 2. Since the fixing frame 5 and the mounting block 2 are bolted together, they can be quickly disassembled when needed (such as for maintenance or cleaning internal processing debris). Finally, use the second bolt 11 to fix the clamping pad 9 inside the mounting groove 10. Before using the device to clamp the workpiece, the operator should first determine whether the material of the clamping pad 9 is suitable according to the workpiece to be clamped. If it is necessary to replace the clamping pad 9, it can be removed by the second bolt 11 and replaced with a suitable clamping pad 9.

[0028] Example 2: Please refer to Figures 4-6 In order to achieve convenient and timely lubrication, this embodiment provides the following technical solution, which specifically discloses: a limiting groove 8 is opened on the inner side of the mounting block 2, and limiting sliders 7 are fixedly installed on the left and right sides of the clamping block 3 to slide in cooperation with the limiting groove 8. A receiving groove 12 is opened inside the clamping block 3, and a water-absorbing sponge 13 is installed inside the receiving groove 12. The water-absorbing sponge 13 absorbs liquid lubricating oil, and a protective cover 14 is installed on the top of the water-absorbing sponge 13. The protective cover 14 and the receiving groove 12 form an up-and-down sliding structure. A discharge hole 15 corresponding to the position of the transmission screw 4 is opened inside the clamping block 3, and the discharge hole 15 is connected to the receiving groove 12 through a connecting groove 16 opened inside the clamping block 3.

[0029] The staff regularly add lubricating oil to the receiving tank 12 through a syringe. The absorbent sponge 13 inside the receiving tank 12 absorbs the lubricating oil to achieve the purpose of storage. When the device needs lubrication after a period of use, the staff presses the protective cover 14 down with a tool (such as tweezers). At this time, the protective cover 14 slides down inside the receiving tank 12. The protective cover 14 squeezes the absorbent sponge 13, and the lubricating oil squeezed out of the absorbent sponge 13 is discharged from the discharge hole 15 through the connecting groove 16. The discharged lubricating oil drips onto the outside of the transmission screw 4, achieving the purpose of lubricating the transmission screw 4.
