Description

Technical Field

[0001] This utility model belongs to the technical field of hardware parts processing fixtures, and specifically relates to a hardware parts processing fixture. Background Technology

[0002] Hardware parts processing fixtures are devices used to clamp and fix hardware parts to be processed. By clamping and fixing the workpiece, the processing accuracy and quality of the workpiece are guaranteed. Common hardware parts processing fixtures mainly consist of a pair of fixed clamping plates, a threaded rod, and a clamping worktable. In use, the threaded rod is usually driven to rotate so that the pair of fixed clamping plates and the clamping worktable cooperate to clamp and fix the workpiece.

[0003] In the existing technology, most hardware parts processing fixtures can only process a single surface of the workpiece after clamping and fixing it. When multiple surfaces of the workpiece need to be processed, the workpiece needs to be disassembled and reassembled multiple times. This not only reduces the processing efficiency of the workpiece, but also causes the processing accuracy of the workpiece to be affected by the multiple clamping errors, resulting in low processing accuracy.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a hardware parts processing fixture.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0031] like Figures 1 to 7 As shown, a hardware accessories processing fixture in one embodiment of the present invention includes: a fixed base 1, a rotary clamping assembly 2, and a support and positioning assembly 3.

[0032] like Figure 1 As shown, the rotary clamping assembly 2 is mounted above the fixed base 1. The rotary clamping assembly 2 includes a support base rod 201, which is fixedly mounted above the fixed base 1. The support base rod 201 serves to limit the assembly and guide the sliding movement of the telescopic rod 202.

[0033] like Figure 4 As shown, a telescopic rod 202 is slidably mounted inside the support base rod 201. The telescopic rod 202 serves to limit the assembly of the limiting pivot 203.

[0034] like Figures 2 to 3 As shown, locking bolts 207 are threaded onto both sides of the support base rod 201. One end of the locking bolt 207 located inside the support base rod 201 is connected to the side wall of the telescopic rod 202. The telescopic rod 202 is locked and fixed by the locking bolt 207 abutting against the side wall of the telescopic rod 202.

[0035] like Figure 4 As shown, one end of the telescopic rod 202 located outside the support base rod 201 is rotatably connected to a limiting shaft 203. The limiting shaft 203 serves to connect the clamping limiting plate 204 and the telescopic rod 202. By rotating the limiting shaft 203 within the telescopic rod 202, the rotation of the clamping limiting plate 204 is controlled, thereby facilitating the simultaneous processing of multiple machining surfaces of the workpiece.

[0036] In addition, the rotation of the limit shaft 203 can be controlled by connecting the output shaft of an external motor to the limit shaft 203 and controlling the operation of the motor.

[0037] like Figures 1 to 3 As shown, a clamping and limiting plate 204 is fixedly connected to one end of the limiting shaft 203. The clamping and limiting plate 204 serves to limit the assembly of the threaded slider 209. At the same time, the workpiece can be clamped and fixed by the cooperation of the clamping and limiting plate 204 and a pair of fixed side plates 205.

[0038] like Figures 1 to 2 As shown, a pair of guide grooves are provided on the side of the clamping and limiting plate 204 opposite to the telescopic rod 202. The guide grooves provide assembly and sliding space for the fixed side plate 205.

[0039] like Figures 1 to 3 As shown, a threaded rod 208 is rotatably connected inside the clamping and limiting plate 204, and the threaded rod 208 passes through a pair of guide grooves. The threaded rod 208 provides support, limiting, and movement control for a pair of threaded sliders 209.

[0040] Specifically, the threaded rod 208 has external threads on both sides with opposite rotation directions, and a pair of threaded sliders 209 can move in opposite directions as the threaded rod 208 rotates under the action of the internal and external threads.

[0041] like Figures 1 to 3 As shown, each of the pair of fixed side plates 205 has an integrally formed threaded slider 209 on the side close to the clamping limiting plate 204. The threaded slider 209 is slidably assembled in the guide groove and is threadedly connected to the threaded rod 208. The threaded slider 209 serves to support, fix, and control the movement of the fixed side plates 205.

[0042] like Figure 6As shown, a control end 210 is fixedly connected to one end of the threaded rod 208 located outside the guide groove. The threaded rod 208 is rotated by controlling the rotation of the control end 210.

[0043] like Figures 1 to 3 As shown, clamping blocks 211 are slidably fitted on the adjacent sides of a pair of fixed side plates 205. The workpiece to be processed is clamped and fixed by the cooperation of the pair of clamping blocks 211.

[0044] Specifically, different clamping blocks 211 can be selected according to the changes in the workpiece's external dimensions.

[0045] like Figures 1 to 3 As shown, a pair of fixed side plates 205 are slidably mounted on the side of the clamping and limiting plate 204 opposite to the telescopic rod 202. The fixed side plates 205 serve to assemble and fix the clamping block 211.

[0046] like Figures 4 to 6 As shown, a pair of positioning support blocks 206 are arranged below the clamping and limiting plate 204. The pair of positioning support blocks 206 support and limit the clamping and limiting plate 204, ensuring the stability of the clamping and limiting plate 204 in use.

[0047] like Figures 4 to 6 As shown, mounting plates 212 are fixedly connected to both sides of the telescopic rod 202. The mounting plates 212 serve to assemble and fix the retractable outer cylinder 213.

[0048] like Figures 4 to 6 As shown, a retractable outer cylinder 213 is fixedly connected to the lower part of each pair of assembly plates 212. The retractable outer cylinder 213 provides support and limits the sliding movement of the piston block 214.

[0049] like Figures 4 to 6 As shown, a piston block 214 is slidably assembled inside the shrinking outer cylinder 213. The piston block 214 serves to support and limit the connecting rod 216.

[0050] like Figures 4 to 6 As shown, a return spring 215 is fixedly connected between the piston block 214 and the retractable outer cylinder 213. The piston block 214 is connected, limited, and pulled back by the contraction and retraction of the return spring 215.

[0051] like Figures 4 to 6 As shown, a connecting rod 216 is fixedly connected between the piston block 214 and the positioning support block 206. The stroke of the connecting rod 216 is greater than half the length of the clamping limit plate 204. The connecting rod 216 serves to connect the piston block 214 and the positioning support block 206, and supports and positions the positioning support block 206 through the connecting rod 216.

[0052] like Figures 6 to 7As shown, the support and positioning assembly 3 is assembled between a pair of fixed side plates 205. The support and positioning assembly 3 includes a support base rod 301, which is fixedly assembled above the fixed base 1. The support base rod 301 provides support, limitation, and sliding guidance for the inner rod 302.

[0053] like Figures 6 to 7 As shown, an inner rod 302 is slidably fitted inside the supporting base rod 301. The inner rod 302 serves to support, fix, and adjust the height of the worktable 303.

[0054] like Figures 6 to 7 As shown, a worktable 303 is fixedly connected to one end of the inner rod 302 outside the supporting bottom rod 301. The worktable 303 supports and limits the bottom of the workpiece clamped between a pair of fixed side plates 205, thereby improving the stability of clamping the workpiece.

[0055] Specifically, a transmission gear cavity is provided inside the supporting base rod 301, which provides assembly and operating space for the drive bevel gear 305 and the transmission bevel gear 306.

[0056] like Figures 6 to 7 As shown, the inner rod 302 is internally threaded with a lifting screw 304. The lifting screw 304 provides support, limit, and lifting / movement control for the inner rod 302.

[0057] like Figures 6 to 7 As shown, a drive bevel gear 305 is fixedly connected to one end of the lifting screw 304 located within the transmission gear cavity. The lifting screw 304 is rotated by rotating the drive bevel gear 305. A transmission bevel gear 306 meshes with one side of the drive bevel gear 305. The transmission bevel gear 306 transmits power to the transmission shaft 307.

[0058] like Figures 6 to 7 As shown, a transmission shaft 307 is fixedly connected inside the transmission bevel gear 306, and the transmission shaft 307 is rotatably mounted within the transmission gear cavity. The transmission shaft 307 provides support, limit, and rotational drive for the transmission bevel gear 306. A lifting end 308 is fixedly connected to one end of the transmission shaft 307 outside the transmission gear cavity. The transmission shaft 307 is rotated by controlling the rotation of the lifting end 308.

[0059] In practical use, the transmission shaft 307 can be rotated by controlling the rotation of the lifting end 308 according to the actual size of the workpiece. The lifting screw 304 rotates synchronously under the meshing action of the driving bevel gear 305 and the transmission bevel gear 306. Through the cooperation of internal and external threads, the inner rod 302 can be raised and lowered synchronously with the rotation of the lifting screw 304, thereby playing the role of height adjustment and control of the worktable 303.

[0060] Subsequently, the workpiece can be placed on the worktable 303, and the threaded rod 208 can be driven to rotate by controlling the rotation of the control end 210. A pair of fixed side plates 205 can move in opposite directions with the rotation of the threaded rod 208 under the action of the internal and external threads. The workpiece is clamped and fixed by the cooperation of the pair of fixed side plates 205 and the clamping block 211.

[0061] When machining is required on the other end of the workpiece, the connecting rod 216 can be extended from the retractable outer cylinder 213 by manually controlling the movement of the positioning support block 206. The worktable 303 can be lowered by rotating the lifting end 308. Subsequently, the workpiece clamped between a pair of fixed side plates 205 can be rotated by rotating the clamping limit plate 204. After rotation, the clamping limit plate 204 can be supported and limited again by the pair of positioning support blocks 206, allowing machining of the various surfaces on the other end of the workpiece.

[0062] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
