[0064] Reference Figure 2-14, embodiments of the present application provide a four-station circular pattern wire drawing machine, which is used to polish the base 100 of a door handle. The four-station circular pattern wire drawing machine includes a feeding mechanism 1, a loading platform mechanism 2, a transfer mechanism 3, and a grinding head mechanism 4. Among them, the feeding mechanism 1 is used to convey a plurality of bases 100 to the transfer position; the loading platform mechanism 2 includes a plurality of self-loading platforms 21, and each self-loading platform 21 is respectively used to carry a base 100, and the self-loading platform 21 can be driven to rotate to drive the carried base 100 to rotate; the transfer mechanism 3 is used to synchronously transfer the four bases 100 at the transfer position to the respective self-loading platforms 21; the grinding head mechanism 4 includes four grinding heads 42, and each grinding head 42 can be arranged on one side of the respective self-loading platform 21 to polish the base 100 on the respective self-loading platform 21.

[0065] The four-station circular pattern wire drawing machine provided by the embodiments of the present application conveys a plurality of bases 100 to the transfer position through the feeding mechanism 1, and synchronously transfers the plurality of bases 100 at the transfer position to the respective self-loading platforms 21 through the transfer mechanism 3; the self-loading platform 21 can be driven to rotate to drive the carried base 100 to rotate; the grinding head mechanism 4 includes four grinding heads 42, and each grinding head 42 can be arranged on one side of the respective self-loading platform 21 to polish the base 100 on the respective self-loading platform 21. It cancels the method of manually holding the base 100 and using a grinding machine for grinding, and can realize the synchronous automatic feeding and grinding of four bases 100, improving the work efficiency and automation level, and improving the grinding quality. In some embodiments, the number of bases 100 synchronously transferred can be two, three, four or more. In the embodiments of the present application, four bases 100 are synchronously loaded, unloaded and transferred at one time. The feeding mechanism 1 can be a conveyor belt.

[0066] Specifically, referring to Figure 2-6 , in some embodiments, the loading platform mechanism 2 further includes a main driving source 22 and a main frame 23. The main driving source 22 has a rotating shaft extending along the vertical direction Z; the main frame 23 includes two side-by-side arranged installation parts, and four self-loading platforms 21 are respectively rotatably arranged on each installation part. The rotating shaft is connected to the main frame 23 to drive the main frame 23 to rotate, so that the two installation parts reciprocally and alternately move between the grinding position and the loading and unloading position; among them, the transfer mechanism 3 can transfer the respective bases 100 at the transfer position to the respective self-loading platforms 21 at the loading and unloading position, and the transfer mechanism 3 can also transfer the respective bases 100 at the loading and unloading position to the transfer position. Each grinding head 42 is used to polish the base 100 carried on the respective self-loading platform 21 at the grinding position.

[0067] Through the above-mentioned arrangement, the main frame 23 is driven to rotate by the main driving source 22 to realize the design of reciprocating and alternating displacement of the two mounting parts between the grinding position and the loading and unloading position. The overall structure is compact and occupies a small space. When the four bases 100 at the grinding position are being ground, the transfer mechanism 3 can transfer each base 100 at the transfer position to the respective transfer platform 21 at the loading and unloading position. After the four bases 100 at the grinding position are finished grinding, the base 100 that has finished grinding can be moved to the loading and unloading position by rotation, while the base 100 that was originally located at the loading and unloading position and has not been ground is synchronously moved to the grinding position and then ground, thereby minimizing the time that the grinding head mechanism 4 stops grinding and improving the working efficiency of the four-station ring grain wire drawing machine.

[0068] Further, refer to Figure 2-3 The feeding mechanism 1 is extended along the first direction X, the grinding head mechanism 4, the stage mechanism 2 and the transfer position are arranged side by side in sequence along the second direction Y perpendicular to the first direction X, the two mounting parts are arranged side by side along the second direction Y, the main driving source 22 drives the main frame 23 to make a 180° stepping rotation, and the layout of each mechanism is compact and reasonable.

[0070] Specifically, refer to Figure 3-6 In some embodiments, the output shafts of the two self-rotating driving sources 24 are respectively connected to the first driving wheels 25, and each transfer platform 21 is respectively connected to the first driven wheel 26; wherein, one of the two first driving wheels 25 is connected to the first driven wheel 26 connected to the four self-transfer platforms 21 provided on one of the two installation parts by belt transmission, and the other of the two first driving wheels 25 is connected to the first driven wheel 26 connected to the four self-transfer platforms 21 provided on the other of the two installation parts by belt transmission, and the belt transmission synchronously drives the rotation of multiple self-transfer platforms 21 located in the same installation part, thereby reducing the number of motors, simplifying the structure and reducing the cost.

[0071] If necessary, refer to Figure 1 and Figure 4, in some embodiments, the base 100 is a housing with a central hole, and the inner wall has convex ribs; a notch 211 is formed on the upper end surface of the self-loading table 21, and the convex ribs can be inserted into the notch 211 to form a limit to prevent rotation, so that the self-loading table 21 can drive the carried base 100 to rotate synchronously.

Since the second translation assembly 313 is an equal-distance variable-distance module and is used to adjust the spacing of a plurality of clamping members 32 arranged in the first direction X, it can arrange a plurality of bases 100 in an equal-distance arrangement along the first direction X, meeting the placement requirements in the scenario of arranging workpieces at equal distances; in addition, the first translation assembly 312 is a cantilever structure extending out of the chassis 33 in the second direction Y perpendicular to the first direction X.

A grinding head bump 422, a feeding tray 423, a receiving tray 424, and a tape clamping assembly 425 are disposed on the grinding head carrier 421. The receiving tray 424 is used for winding up the grinding abrasive belt 200 pulled out from the feeding tray 423. The tape clamping assembly 425 is used for clamping the grinding abrasive belt 200. The grinding head bump 422 is configured to press against the grinding abrasive belt 200 between the feeding tray 423 and the receiving tray 424.

[0087] Since it has four grinding heads 42 and the grinding heads 42 are disposed on the position adjusting member 41, the positions of the grinding heads 42 can be adjusted, thereby improving the flexibility of the device and the synchronous processing ability of the multiple bases 100 of the device. In addition, the feeding tray 423 and the receiving tray 424 cooperate, and the grinding abrasive belt 200 pressed between the feeding tray 423 and the receiving tray 424 can be continuously adjusted by the way of the receiving tray 424 for receiving materials and the feeding tray 423 for feeding materials, that is, the grinding abrasive belt 200 to be used is automatically updated, that is, the abrasive belt pressed by the grinding head bump 422 is updated, and the structure is more flexible and the use is also more flexible.

[0088] Further, the third translation assembly 411 and the second lifting assembly 412 are respectively slide rail slider linear displacement modules. The slide rail slider linear displacement module can adopt an existing linear displacement device, and specific limitations are not made.

[0089] Furthermore, referring to the reference figure Figure 10 , Figure 13 and Figure 14 , there are four grinding heads 42. The position adjusting member 41 further includes two adapter brackets 413 respectively connected to the output ends of the second lifting assembly 412. Two grinding heads 42 are respectively disposed on each adapter bracket 413. The four grinding heads 42 are arranged at equal intervals and side by side along the first direction X. Two grinding heads 42 are respectively disposed on each adapter bracket 413 to form a group, and then they are assembled on the position adjusting member 41. By fixing the adapter bracket 413 to the output end of the second lifting assembly 412, two grinding heads 42 can be synchronously fixed. After being grouped and then assembled, the assembly is more convenient.

[0090] Further, as Figure 10-12 shown, the grinding head bump 422 includes a main body portion 4221 and a protruding portion 4222. The main body portion 4221 is connected to the grinding head carrier 421; the protruding portion 4222 protrudes from the main body portion 4221, and the protruding portion 4222 is configured to abut against the abrasive belt 200 between the material feeding tray 423 and the material receiving tray 424; wherein, the surface of the protruding portion 4222 pressing against the abrasive belt 200 includes a first plane L1, a second plane L2, and a fillet surface L3 located between the first plane L1 and the second plane L2 and smoothly and transitionally connected to the first plane L1 and the second plane L2 respectively. The included angle α between the first plane L1 and the second plane L2 is 20° - 35°. The included angle α between the first plane L1 and the second plane L2 being 20° - 35° can enable the protruding portion 4222 to form a protruding end abutting against the abrasive belt 200, so as to abut against the abrasive belt 200 through the fillet surface L3 of the protruding end, and enable the abrasive belt 200 to form a convex surface for grinding the base 100. The included angle α being 20° - 35° can form a relatively sharp protruding fillet, so as to enable the abutted abrasive belt 200 to form a relatively sharp protruding grinding surface. Compared with the grinding head bump 422 above 35°, especially about 70°, its grinding surface is smaller, which can reduce the possibility of interference between the first plane L1 and the second plane L2 and the base 100, and is convenient for grinding some smaller parts.

[0091] Further, referring to Figure 10 , the grinding head 42 further includes a tensioning roller 426. The tensioning roller 426 is rotatably arranged on the grinding head carrier 421. The tensioning roller 426 is used to abut against the abrasive belt 200 to tension the abrasive belt 200 so that the abrasive belt 200 maintains a certain tension.

[0092] Furthermore, for the material receiving of the material receiving tray 424. Referring to Figure 10 , the grinding head 42 further includes a material receiving driving source 427. The material receiving driving source 427 can be a motor: The material receiving driving source 427 is arranged on the grinding head carrier 421 and is drivingly connected to the material receiving tray 424 to drive the material receiving tray 424 to rotate for material receiving.

[0093] Further, referring to Figure 10-14 , there is at least one material belt clamping assembly 425. The at least one material belt clamping assembly 425 is used to clamp one end of the abrasive belt 200 close to the material feeding tray 423. The material belt clamping assembly 425 clamps the abrasive belt 200, so that when the abrasive belt 200 is used for grinding, it is abutted by the grinding head bump 422 and cooperates with the clamping of the material belt clamping assembly 425 to realize position fixation.

[0094] Referring to Figure 10-14, in an embodiment of the present application, there are two tape clamping assemblies 425. One of the tape clamping assemblies 425 is used to clamp the first end of the grinding abrasive belt 200 between the feeding reel 423 and the take-up reel 424, and the other tape clamping assembly 425 is used to clamp the second end of the grinding abrasive belt 200 between the feeding reel 423 and the take-up reel 424. The grinding head bump 422 is configured to press against the grinding abrasive belt 200 between the first end and the second end. Furthermore, the clamping of the grinding abrasive belt 200 is completely achieved by the two tape clamping assemblies 425, so that the grinding head bump 422 can press against the grinding abrasive belt 200. In some embodiments, the tension of the grinding abrasive belt 200 can also be provided by controlling the rotation of the take-up drive source 427.

[0095] Furthermore, referring to Figure 10-14 , the tape clamping assembly 425 includes a clamping cylinder 4251, a first clamping block 4252, and a second clamping block 4253. The clamping cylinder 4251 is disposed on the grinding head carrier 421; the first clamping block 4252 is fixed to the grinding head carrier 421, and the first clamping block 4252 is located on one side of the grinding abrasive belt 200 between the take-up reel 424 and the feeding reel 423; the second clamping block 4253 is fixed to the output end of the clamping cylinder 4251 and is spaced apart from the first clamping block 4252. The clamping cylinder 4251 is used to drive the second clamping block 4253 to approach or move away from the first clamping block 4252, thereby realizing the clamping of the grinding abrasive belt 200. The structure is simple and the cost is low.
