[0002] The sun gear is a basic component of the planetary gear system. In a planetary gear system, the external gear that serves as the central gear is called the sun gear. In a planetary gear structure, the sun gear is used as the driving gear of the planetary gear structure to drive the planetary gear structure to rotate. In order to adjust the transmission ratio of the sun gear, a second-stage sun gear is required. When machining the second-stage sun gear, a sun gear lathe fixture is required.

[0003] After frequent use, fixtures need to be replaced or repaired. However, traditional fixtures are mostly fixed to the workbench by multiple fastening bolts, which involves many steps of disassembly and assembly, making them cumbersome and slow to replace or repair.

[0004] Therefore, there is a need for a sun gear lathe fixture that is easy to assemble and disassemble. Utility Model Content

[0005] The purpose of this utility model is to provide a sun gear lathe fixture that is easy to disassemble and assemble, so as to solve the problem mentioned in the background art that most traditional fixtures are fixed to the worktable by multiple fastening bolts, and the disassembly, replacement or maintenance is slow.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sun gear lathe fixture that is easy to assemble and disassemble, comprising a worktable and a mounting plate. The mounting plate is provided with a quick assembly / disassembly mechanism. An mounting component is fixedly mounted on the top surface of the worktable, and a fixing mechanism is provided on the top surface of the mounting component. The quick assembly / disassembly mechanism includes a sliding ring. An mounting groove is fixedly opened inside the mounting plate. The bottom surface of the mounting groove is fixedly connected to the bottom surface of the sliding ring. A sliding toothed ring is slidably mounted on the top side of the sliding ring. An mounting pin is provided inside the mounting plate. A gear is rotatably mounted on the side of the mounting pin via a bearing. A limit block is fixedly set inside the mounting plate. A sliding groove is fixedly opened on the side of the limit block. A slide bar is slidably mounted on the inner wall of the sliding groove. A rack belt is fixedly mounted on the side of the slide bar. The tooth surface of the rack belt meshes with the tooth surface of the gear. The tooth surface of the gear meshes with the tooth surface of the sliding toothed ring. A locking slot is fixedly opened on the inner wall of the mounting component, and a locking block is fixedly mounted on the end face of the rack belt.

[0007] Preferably, a connecting block is fixedly installed on the side of the sliding toothed ring, a first insertion hole is opened through the top surface of the connecting block, and a second insertion hole is fixedly opened on the end face of the connecting block.

[0008] Preferably, the mounting plate has a guide ring inside, the bottom end face of the connecting block has a groove fixedly opened, the inner wall of the groove engages with the side of the guide ring, and a clamp is fixedly installed on the fixed end face of the mounting plate.

[0009] Preferably, the top surface of the workbench is fixedly connected to the bottom surface of the mounting component, and the inner wall of the mounting component engages with the side surface of the mounting plate.

[0010] Preferably, the fixing mechanism includes a mounting ring, and three pins are fixedly mounted on the bottom end face of the mounting ring.

[0011] The mounting plate has three guide blocks fixedly installed on its side. The inner wall of the mounting component has three guide grooves fixedly opened, and the inner wall of the guide grooves engages with the guide blocks.

[0012] Preferably, the mounting component has a third insertion hole at the top and bottom, and the inner wall of the third insertion hole corresponds to the first insertion hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This easy-to-assemble and disassemble sun gear lathe fixture first aligns the guide block with the guide groove and presses down the fixture. At this time, insert the lever into the second insertion hole and drive the connecting block to rotate. This further drives the sliding gear ring connected to the end face of the connecting block to slide on the surface of the sliding ring. The teeth inside the sliding gear ring drive the gear meshing with it to rotate, which drives the rack belt to perform transmission. As the rack belt moves, it pushes the clamping block into the inner wall of the bayonet. At this time, the first insertion hole on the connecting block moves just below the third insertion hole on the top surface of the mounting part. Then, insert the pin into the third insertion hole and the first insertion hole to fix it, thus completing the installation of the fixture. When disassembling, first pull out the pin, insert the pin into the second insertion hole and rotate it in the opposite direction to disengage the clamping block from the bayonet. At this time, the fixture can be removed and the mounting part can be used for inspection and maintenance of the fixture. This can effectively improve the speed and efficiency of fixture assembly and disassembly.

[0015] 2) Before installation, the guide block installed on the side of the mounting plate should be aligned with the guide groove on the inner wall of the mounting component. At this time, the connecting block should be matched with the groove on the top of the mounting component by the limiting of the guide block and the guide groove. Then, press the fixture down and rotate the connecting block by the pin to drive the locking block to engage with the locking slot. After installation, the connecting block may fall out of position due to the lack of fixing of the connecting block, causing the locking block to fall out of the locking slot. Therefore, insert the pin installed on the bottom end face of the mounting ring into the third insertion hole of the mounting component. At this time, the connecting block and the mounting component can be fixed by the pin to prevent the connecting block from moving. This can effectively improve the stability of the fixture fixation of the mechanism and prevent safety hazards. Attached Figure Description

[0024] 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.

[0025] Example 1

[0026] Combination Figures 1-7A detachable and detachable sun gear lathe fixture includes a worktable 1 and a mounting plate 6. The mounting plate 6 has a quick-release mechanism 3 inside. A mounting component 2 is fixedly mounted on the top surface of the worktable 1, and a fixing mechanism 4 is provided on the top surface of the mounting component 2. The quick-release mechanism 3 includes a sliding ring 302. A mounting groove is fixedly formed inside the mounting plate 6, and the bottom surface of the mounting groove is fixedly connected to the bottom surface of the sliding ring 302. A sliding gear ring 303 is slidably mounted on the top side of the sliding ring 302. A mounting pin 311 is provided inside the mounting plate 6, and a gear 312 is rotatably mounted on the side of the mounting pin 311 via a bearing. A limit block 307 is fixedly formed inside the mounting plate 6, and a sliding groove is fixedly formed on the side of the limit block 307. The inner wall of the sliding groove slides... A slide bar 308 is installed, and a rack belt 309 is fixedly installed on the side of the slide bar 308. The tooth surface of the rack belt 309 meshes with the tooth surface of the gear 312. The tooth surface of the gear 312 meshes with the tooth surface of the sliding gear ring 303. A slot 301 is fixedly opened on the inner wall of the mounting part 2. A locking block 310 is fixedly installed on the end face of the rack belt 309. A connecting block 304 is fixedly installed on the side of the sliding gear ring 303. A first insertion hole 305 is opened through the top surface of the connecting block 304. A second insertion hole 306 is fixedly opened on the end face of the connecting block 304. A guide ring 313 is provided inside the mounting plate 6. A sliding groove is fixedly opened on the bottom end face of the connecting block 304. The inner wall of the sliding groove meshes with the side of the guide ring 313. A clamp 5 is fixedly installed on the fixed end face of the mounting plate 6.

[0027] Specifically, in use, when the clamp 5 needs to be installed, first align the connecting block 304 with the groove opened in the mounting part 2, and at the same time align the guide block 401 installed on the side of the mounting plate 6 with the guide groove 402. At this time, insert the lever into the second insertion hole 306 and drive the connecting block 304 to rotate, which in turn drives the sliding toothed ring 303 connected to the end face of the connecting block 304 to slide on the surface of the sliding ring 302. The teeth inside the sliding toothed ring 303 drive the gear 312 that meshes with it to rotate, which in turn drives the rack belt 309 to perform transmission. When the rack belt 309 is in transmission, it is limited by the sliding groove opened inside the sliding bar 308 and the limiting block 307, which further drives the rack belt 309 to perform transmission. The locking block 310, which is mounted on the end face of the rack belt 309, moves outward. As the rack belt 309 moves, the locking block 310 is pushed into the inner wall of the bayonet 301. At this time, the first insertion hole 305 on the connecting block 304 moves to the bottom of the third insertion hole 403 on the top surface of the mounting part 2. The pin 405 is then inserted into the third insertion hole 403 and the first insertion hole 305 for fixation, thus completing the installation of the clamp 5. When disassembling, inspecting and maintaining, the pin 405 is first pulled out, and the lever is inserted into the second insertion hole 306 and rotated in the opposite direction to disengage the locking block 310 from the bayonet 301. At this time, the clamp 5 can be removed from the mounting part 2 for inspection and maintenance.

[0028] Example 2

[0029] See Figures 1-7Furthermore, the top surface of the workbench 1 is fixedly connected to the bottom surface of the mounting component 2, the inner wall of the mounting component 2 engages with the side of the mounting plate 6, the fixing mechanism 4 includes a mounting ring 404, a pin 405 is fixedly installed on the bottom surface of the mounting ring 404, and there are three pins 405. A guide block 401 is fixedly installed on the side of the mounting plate 6, and there are three guide blocks 401. Three guide grooves 402 are fixedly opened on the inner wall of the mounting component 2, and the inner wall of the guide grooves 402 engages with the guide blocks 401. The mounting component 2 has a third insertion hole 403 opened at the top and bottom, and the inner wall of the third insertion hole 403 corresponds to the first insertion hole 305.

[0030] Specifically, before installation, the guide block 401 installed on the side of the mounting plate 6 is aligned with the guide groove 402 opened on the inner wall of the mounting part 2. At this time, the connecting block 304 is just matched with the groove opened on the top of the mounting part 2 by the limiting of the guide block 401 and the guide groove 402. Then, the clamp 5 is pressed down and the connecting block 304 is rotated by the lever, which in turn drives the locking block 310 to engage with the locking slot 301. After installation, due to the lack of fixation for the connecting block 304, the connecting block 304 may fall out of its position, causing the locking block 310 to fall out of the locking slot 301. Therefore, the pin 405 installed on the bottom end face of the mounting ring 404 is inserted into the third insertion hole 403 opened on the mounting part 2. At this time, the connecting block 304 and the mounting part 2 can be fixed by the pin 405 to prevent the connecting block 304 from moving and improve the stability of the mechanism for fixing the clamp 5.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
