Technical Field
[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a high-efficiency titanium alloy workpiece clamping device. Background Art
[0002] Titanium alloy refers to a variety of alloy metals made of titanium and other metals. Titanium is an important structural metal developed in the 1950s. Titanium alloy has high strength, good corrosion resistance and high heat resistance. At present, in the process of processing titanium alloy products, the dimensional tolerance of the titanium alloy products after processing cannot fully meet the requirements of the drawings, and the clamping force of the fixture used to fix the titanium alloy workpiece during processing of titanium alloy products is not easy to control, which leads to the easy scrapping of the titanium alloy workpiece after processing, and it is difficult to ensure the accuracy of small batch production. To this end, we propose an efficient titanium alloy workpiece fixture device. Utility Model Content
[0003] In view of the problems in the prior art, the utility model provides a high-efficiency titanium alloy workpiece clamping device.
[0004] The technical solution adopted by the utility model to solve its technical problems is a high-efficiency titanium alloy workpiece clamp device, which is characterized in that it includes a clamp body, a wedge is slidably installed in the clamp body, and a sleeve is installed on the outer wall surface of the wedge body, a screw threadedly connected to a pull rod is installed on the inner side of the sleeve, an oblique groove is preset on the outer periphery of the wedge body, and there are three groups of oblique grooves, a sliding block inserted into the oblique groove is slidably installed on the inner side of the clamp body, and there are three groups of sliding blocks, and one end of the sliding block located on the outer side of the clamp body is equipped with a claw through a bolt.
[0005] By adopting the above technical scheme, when the fixture is used to clamp the titanium alloy workpiece, the pull rod can be connected to the piston rod of the cylinder, so that when the pull rod moves, it can drive the sleeve and the wedge inside the clamp body to move axially, and because the configuration part of the slider is inserted into the inclined groove on the outer periphery of the wedge body, when the wedge body moves axially, it can force the slider to drive the claws connected to it to move radially, so that the three groups of claws can be used to clamp or release the titanium alloy workpiece, which is convenient for processing. Moreover, since the contact area of the inclined surface is large, the wear is small and the precision is high, and the clamping force of the clamp body can be controlled, thereby reducing the situation of scrap when the titanium parts are clamped subsequently, and the precision of the workpiece can be guaranteed during small batch production.
[0006] Specifically, the pull rod and the clamp body are both equipped with top columns.
[0007] By adopting the above technical solution, the top column inside the pull rod can easily reduce the loose connection between the screw and the pull rod, and when the top column inside the clamp body is separated from the slider and the wedge, it can prevent the slider from automatically falling.
[0008] Specifically, the three groups of inclined grooves are evenly distributed on the outer periphery of the wedge.
[0009] By adopting the above technical solution, the three groups of inclined grooves are evenly distributed on the periphery of the wedge body and distributed at 15 degrees along the circumference of the wedge body, so that the configuration part of the outer periphery of the slider can be smoothly plugged into the inclined grooves, which is convenient for driving the slider to move when the wedge body moves subsequently.
[0010] Specifically, a spring abutting against the wedge is installed in the clamp body.
[0011] By adopting the above technical solution, the spring inside the clamp body can help reduce the deflection of the wedge body caused by vibration.
[0012] Specifically, a hexagonal hole is provided on one side of the wedge body located outside the clamp body.
[0013] By adopting the above technical solution, the hexagonal holes on the outer periphery of the wedge body are conveniently connected to the plug wrench, and can drive the wedge body to rotate in a counterclockwise direction, so that the configuration part of the slider can be separated from the wedge body, making it easy to disassemble the slider.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] The technical solution of the present application is designed with a pull rod, a screw, a sleeve, a wedge, a slider and a claw. When the fixture is used to clamp the titanium alloy workpiece, the pull rod can be connected to the piston rod of the cylinder, so that when the pull rod moves, it can drive the sleeve and the wedge inside the clamp to move axially. Moreover, since the configuration part of the slider is mutually inserted into the inclined groove on the outer periphery of the wedge, when the wedge moves axially, it can force the slider to drive the claw connected to it to move radially, so that the three groups of claws can be used to clamp or release the titanium alloy workpiece, which is convenient for processing. Moreover, since the contact area of the inclined surface is large, the wear is small and the precision is high, and the clamping force of the clamp can be controlled, thereby reducing the occurrence of scrap when the titanium parts are clamped subsequently, and ensuring the precision of the workpiece during small batch production.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0021] See also Figure 1-2 The embodiment of the utility model provides a technical solution: an efficient titanium alloy workpiece clamping device, characterized in that it includes a clamping body 1, a wedge 2 is slidably installed inside the clamping body 1, and a sleeve 5 is installed on the outer wall surface of the wedge 2, and a screw 3 threadedly connected to a pull rod 6 is installed on the inner side of the sleeve 5, an oblique groove is preset on the outer periphery of the wedge 2, and there are three groups of oblique grooves, a slider 7 inserted into the oblique groove is slidably installed on the inner side of the clamping body 1, and there are three groups of sliders 7, and one end of the slider 7 located on the outer side of the clamping body 1 is equipped with a claw 8 through a bolt.
[0022] During use, when the fixture is used to clamp the titanium alloy workpiece, the pull rod 6 can be interconnected with the piston rod of the cylinder, so that when the pull rod 6 moves, it can drive the sleeve 5 and the wedge 2 inside the clamp body 1 to move axially, and because the configuration part of the slider 7 is mutually inserted into the inclined groove on the outer periphery of the wedge body 2, when the wedge body 2 moves axially, it can force the slider 7 to drive the claws 8 connected thereto to move radially, so that the three groups of claws 8 can be used to clamp or release the titanium alloy workpiece, which is convenient for processing. Moreover, since the contact area of the inclined surface is large, the wear is small and the precision is high, and the clamping force of the clamp body 1 can be controlled, thereby reducing the situation of scrap when the titanium parts are clamped subsequently, and the precision of the workpiece can be guaranteed during small batch production.
[0023] like Figure 1 As shown, the pull rod 6 and the clamp body 1 are both equipped with a top column 4.
[0024] When in use, the top column 4 inside the pull rod 6 is convenient for reducing the loose connection between the screw 3 and the pull rod 6, and when the top column 4 inside the clamp body 1 is separated from the slider 7 and the wedge 2, it is convenient to prevent the slider 7 from automatically falling.
[0025] like Figure 1 As shown, three groups of inclined grooves are evenly distributed on the outer periphery of the wedge 2.
[0026] When in use, the three groups of inclined grooves are evenly distributed on the outer periphery of the wedge 2 and are distributed at 15 degrees along the circumference of the wedge 2, so that the configuration part of the outer periphery of the slider 7 can be smoothly plugged into the inclined grooves, making it easy to drive the slider 7 to move when the wedge 2 moves later.
[0027] like Figure 2 As shown, a spring 9 abutting against the wedge 2 is assembled in the clamp body 1 .
[0028] When in use, the spring 9 inside the clamp body 1 is convenient for reducing the deflection of the wedge body 2 due to vibration.
[0029] like Figure 2 As shown, a hexagonal hole is provided on one side of the wedge body 2 located outside the clamp body 1 .
[0030] When in use, the hexagonal holes on the outer periphery of the wedge 2 are conveniently connected to the plug wrench, which can drive the wedge 2 to rotate in the counterclockwise direction, so that the configuration part of the slider 7 can be separated from the wedge 2, making it easy to disassemble the slider 7.
[0031] The working principle and use process of the utility model are as follows: when in use, first install the corresponding structural components in a suitable position, and when the fixture is used to clamp the titanium alloy workpiece, the pull rod 6 can be connected to the piston rod of the cylinder, so that when the pull rod 6 moves, it can drive the sleeve 5 and the wedge 2 inside the clamp body 1 to move axially, and because the configuration part of the slider 7 is plugged into the oblique groove on the outer periphery of the wedge 2, when the wedge 2 moves axially, it can force the slider 7 to drive the claws 8 connected thereto to move radially, so that the three groups of claws 8 can be used to clamp or release the titanium alloy workpiece, which is convenient for processing, and because The contact area of the inclined surface is large, so the wear is small and the precision is high. Because of the force-increasing effect of the inclined surface, sufficient clamping force can be generated, and the clamping force of the clamp body 1 can be controlled, thereby reducing the situation of scrap when the titanium parts are clamped in the subsequent process, and ensuring the precision of the workpiece in small batch production. At the same time, the axial movement is converted into radial centering clamping by utilizing the principle of inclined surface action, so that the radial clamping stroke of the clamp body 1 is smaller, thereby improving the clamping efficiency of the workpiece, so as to improve the subsequent processing effect of the titanium parts. At the same time, the clamp body 1 is only suitable for the clamping of a batch of workpieces whose positioning surface sizes do not change much.
[0032] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model.
