Description

Technical Field

[0001] This application relates to the technical field of weight processing equipment, and in particular to a lathe for weight processing. Background Art

[0002] Standard weights are weights used as reference weights, for example, in verification institutions or in corresponding certified companies, in order to calibrate scales, especially precision scales, or to calibrate other weights of lower accuracy grades.

[0003] When processing weights, tools on the lathe body are required to fix the weights and process both ends and the side walls of the weights. When processing the weights to be processed, in order to achieve different processing effects, different tools need to be used for processing. There is a need to replace the lathe body to process the weights or disassemble and assemble the tools to replace the processing tools during the processing, resulting in low processing efficiency. Summary of the Utility Model

[0004] In order to improve the efficiency when processing weights to be processed, this application provides a lathe for weight processing.

[0005] This application provides a lathe for weight processing, adopting the following technical solutions:

[0006] A lathe for weight processing includes a lathe body. A workbench for supporting tools is horizontally arranged on the lathe body. A fixing table for fixing the weight to be processed is vertically arranged on the lathe body. A fixing shaft is fixedly arranged at the center position of the workbench. A fixing plate rotatably connected to the fixing shaft is arranged on the workbench. A plurality of mounting parts for fixing tools are arranged on the upper surface of the fixing plate. The mounting parts are circumferentially and equally spaced around the axis of the fixing shaft and installed on the workbench. An upper top plate for clamping the mounting parts is arranged at the upper end of the fixing shaft. The fixing shaft passes through the center of the upper top plate.

[0007] By adopting the above technical solutions, when processing the weight to be processed, the weight to be processed is fixed on the fixing table. The upper top plate and the fixing plate clamp the mounting parts in the middle. The fixing plate and the upper top plate rotate on the workbench through the fixing shaft to adjust the positions of the mounting parts, facilitating the adjustment of the positions of different specifications of tools, and adjusting the tools used for processing to face the fixing table, thereby improving the processing efficiency.

[0008] Optionally, a fixing ring is fixedly arranged on the side of the upper top plate away from the fixing plate. A number of fixing holes equal to the number of mounting parts are circumferentially and equally spaced on the fixing ring. Threaded holes of the same size as the fixing holes are opened at the upper end of the fixing shaft. A limit bolt passing through the fixing hole and extending into the threaded hole is arranged on the fixing shaft.

[0009] By adopting the above technical solution, the upper top plate can be conveniently fixed to the fixed shaft by inserting the limit bolt through the fixing hole into the threaded hole. When adjusting the position of the mounting member, the rotated upper top plate can be conveniently fixed to the fixed shaft through the fixing holes in different directions on the fixing ring.

[0010] Optionally, a connecting shaft corresponding to each mounting member is provided between the upper top plate and the fixing plate. The connecting shaft passes through the mounting member from bottom to top and is rotatably connected to the upper top plate.

[0011] By adopting the above technical solution, the mounting member rotates between the upper top plate and the fixing plate through the connecting shaft, which is beneficial to adjusting the direction of the mounting member and conveniently adjusting the orientation of the tool to achieve different machining effects.

[0012] Optionally, limiting holes are provided on both sides of the connecting shaft on the upper end surface of the fixing plate. Through holes matching the positions of the limiting holes are provided on the mounting member. A limiting member is arranged in the through hole, and the length of the limiting member is greater than the height of the through hole.

[0013] By adopting the above technical solution, the limiting member extends out from the lower end of the through hole and is inserted into the limiting hole, which is convenient for fixing the mounting member on the fixing plate. By adjusting the position of the limiting member upward, the lower end of the limiting member is received into the through hole, which is convenient for rotating the mounting member and adjusting the orientation of the tool.

[0014] Optionally, a reset groove is provided on the inner wall of the through hole. A reset block located in the reset groove is fixedly arranged on the limiting member. A reset spring is fixedly arranged between the reset block and the upper inner wall of the reset groove. When the reset spring is in a natural state, the limiting member extends out from the lower end of the through hole and is inserted into the limiting hole.

[0015] By adopting the above technical solution, when the limiting member is adjusted upward so that the through hole is located above the limiting hole, releasing the limiting member causes the limiting member to automatically extend out from the lower end of the through hole and be inserted into the limiting hole through the reset spring.

[0016] Optionally, the lower end of the limiting member is tapered.

[0017] By adopting the above technical solution, when the mounting member is rotated and the limiting member contacts the fixing plate, the limiting member can automatically adjust its position upward. When the limiting member is located above the limiting hole, the reset spring gives the limiting member a downward pressure to make the limiting member automatically inserted into the limiting hole.

[0018] Optionally, a mounting hole is provided at the upper end of the mounting member. A tool hole of the same size as the mounting hole is provided on the tool. A fixing bolt passing through the mounting hole and extending into the tool hole is provided on the upper end surface of the mounting member.

[0019] By adopting the above technical solution, the fixing bolt passes through the mounting cylinder and is inserted into the tool hole to connect the tool with the mounting member, and the tool can be conveniently replaced by inserting and removing the fixing bolt.

[0020] Optionally, a plurality of fixing screws are fixed on the fixing plate, the fixing screws pass through the upper top plate, and two fixing nuts for clamping the upper top plate are threadedly connected to the fixing screws, and the upper top plate is located between the two fixing nuts.

[0021] By adopting the above technical solution, by rotating the fixing nut, the position of the upper top plate can be conveniently adjusted, and the upper top plate is adjusted downward so that the upper top plate and the fixing plate clamp the mounting member, which is beneficial to improving the stability during processing.

[0022] Optionally, a rubber pad for fixing the mounting member is provided on the lower end surface of the upper top plate.

[0023] By adopting the above technical solution, the rubber pad enhances the friction between the upper top plate and the mounting member, so that when the tool is processed, the fixing of the upper top plate and the fixing plate to the mounting member is more stable.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] Through the arrangement of the fixed shaft, the fixing plate, the connecting shaft, and the upper top plate, the upper top plate and the fixing plate rotate on the workbench through the fixed shaft, which is convenient for adjusting the position of the mounting member equipped with different types of tools to achieve different processing effects, and is beneficial to improving the processing efficiency;

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] The embodiment of the present application discloses a lathe for processing weights.

[0035] like Figure 1 and Figure 2 , comprising a bed 1, a workbench 2 for supporting a tool 5 is horizontally arranged on the bed 1, and a fixing table 3 for fixing a weight to be processed is vertically arranged on the bed 1.

[0036] like Figure 1 A three-jaw chuck 31 is installed on the fixed platform 3, and the weight to be processed is fixed on the fixed platform 3 through the three-jaw chuck 31. The three-jaw chuck 31 rotates, and the tool 5 processes the weight to be processed.

[0037] like Figure 1 The bed 1 is horizontally provided with a transverse track 11 and a vertical track 12 which are perpendicular to each other. The vertical track 12 is slidably connected to the transverse track 11, and the workbench 2 is slidably connected to the vertical track 12. The workbench 2 is adjusted in position by the transverse track 11 and the vertical track 12, and the tool 5 on the workbench 2 processes the weight to be processed which is fixed on the fixed table 3.

[0038] like Figure 1 and Figure 2 A fixed shaft 21 is fixedly arranged on the workbench 2, a fixed plate 22 rotatably connected to the fixed shaft 21 is arranged on the workbench 2, an upper top plate 23 rotatably connected to the fixed shaft 21 is arranged on the upper end of the fixed shaft 21, a mounting member 4 for fixing a tool 5 is installed between the upper top plate 23 and the fixed plate 22, different types of tools 5 are installed on different mounting members 4, and the mounting members 5 are equidistantly installed on the workbench 2 with the axis of the fixed shaft 21 as the center. The upper top plate 23 and the fixed plate 22 rotate on the workbench 2 through the fixed shaft 21, which facilitates the adjustment of the position of the mounting member 4, so that the tool 5 required for processing is adjusted to the direction facing the fixed table 3 to process the weight to be processed.

[0039] like Figure 2, a plurality of fixing screws 7 are fixed on the fixing plate 22. The fixing screws 7 pass through the upper top plate 23, and two fixing nuts 71 for clamping the upper top plate 23 are threadedly connected to the fixing screws 7. The upper top plate 23 is located between the two fixing nuts 71. By turning the fixing nuts 71, it is convenient to adjust the position of the upper top plate 23. Adjust the position of the upper top plate 23 downward so that the upper top plate 23 abuts against the mounting member 4, and the upper top plate 23 and the fixing plate 22 clamp the mounting member 4, which is beneficial to improving the stability of the cutting tool 5 during the processing.

[0040] As Figure 2 , a rubber pad 231 for fixing the mounting member 4 is provided on the lower end surface of the upper top plate 23. The rubber pad 231 enhances the friction between the upper top plate 23 and the mounting member 4, which is beneficial to improving the clamping effect of the upper top plate 23 and the fixing plate 22 on the mounting member 4.

[0041] As Figure 3 , a fixing ring 8 is fixedly provided on the upper end surface of the upper top plate 23. A fixing hole 211 corresponding to the connecting shaft 24 is opened on the fixing ring 8. A threaded hole 211 with the same size as the opening is opened at the upper end of the fixing shaft 21. A limit bolt 25 is provided to pass through the fixing hole 211 and extend into the threaded hole 211. After the positions of the upper top plate 23 and the fixing plate 22 are adjusted, when the mounting member 4 is clamped by the upper top plate 23 and the fixing plate 22, the limit bolt 25 is passed through the fixing hole 211 and inserted into the threaded hole 211, which is convenient to fix the upper top plate 23 and the fixing shaft 21.

[0042] As Figure 2 , a connecting shaft 24 corresponding to the mounting member 4 is provided between the upper top plate 23 and the fixing plate 22. The connecting shaft 24 passes through the mounting member 4 from bottom to top and the upper top plate 23, and the mounting member 4 is rotatably connected to the connecting shaft 24. By rotating the mounting member 4, it is convenient to adjust the orientation of the cutting tool 5, which is beneficial to achieving different processing effects.

[0043] As Figure 2 And Figure 4 , limiting holes 26 are opened on both sides of the connecting shaft 24 on the upper end surface of the fixing plate 22. Through holes matching the limiting holes 26 are opened on the mounting member 4. A limiting member 6 is installed in the through hole. The length of the limiting member 6 is greater than the height of the mounting member 4. A reset groove 41 is opened on the inner wall of the through hole. A reset block 62 located in the reset groove 41 is fixedly installed on the limiting member 6.

When the limiting member 6 extends out from the lower end of the through hole and is inserted into the limiting hole 26, the reset spring 61 is in a natural state. By adjusting the limiting member 6 upward, the lower end of the limiting member 6 retracts into the through hole, and it is convenient to rotate the mounting member 4 to adjust the direction of the cutting tool 5. Release the limiting member 6, and the reset spring 61 is compressed by the reset block 62 to give the reset block 62 a downward pressure, so that the limiting member 6 extends out from the through hole and is inserted into the limiting hole 26 to connect the mounting member 4 and the fixing plate 22.

[0044] As Figure 4 , the lower end of the limiting hole 26 is conical. When the rotating mounting member 4 is rotated to make the limiting member 6 contact the fixed plate 22, during the rotation process, the limiting member 6 can automatically adjust its position upward and slide into the limiting hole 26 to connect the mounting member 4 with the fixed plate 22.

[0045] As Figure 5 , a mounting hole 42 is provided at the upper end of the mounting member 4, a tool hole 51 of the same size as the mounting hole 42 is provided on the tool 5, and a fixing bolt 421 is provided which passes through the mounting hole 42 and is inserted into the tool hole 51 to connect the tool 5 with the mounting member 4. By loading and unloading the fixing bolt 421, it is convenient to replace the tool 5 in the mounting member 4 to achieve different processing effects on the weight to be processed.

[0046] The implementation principle of the lathe for weight processing in the embodiment of the present application is as follows: The tool 5 required for processing the weight to be processed is installed in different mounting members 4. By rotating the upper top plate 23 and the fixed plate 22, the positions of different types of tools 5 are adjusted.
