Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a gear clamping fixture. Background Technology

[0002] A gear shaper is a metal cutting machine tool that mainly uses a gear shaper cutter to process internal gears and other gear parts using the generating method. During gear shaping, the gear shaper cutter makes a reciprocating cutting motion while rolling relative to the workpiece. Specifically, a gear shaper fixture is fixedly installed on the worktable of the gear shaper for gear processing.

[0003] Existing technology, patent CN212682703U, discloses a gear shaping fixture, including a base plate fixedly mounted on the worktable of a gear shaping machine. The base plate is circular, and at least three sets of clamping assemblies for positioning the gear are evenly distributed along its circumference. Each clamping assembly includes a support column supported at the bottom of the gear, a guide rod tangent to the inner wall of the gear, and a pressing unit acting downwards on the upper end face of the gear to press it down. The pressing unit includes a cylinder with a piston rod pointing vertically upwards. The top of the piston rod is hinged to a pressing block, and the middle of the pressing block is hinged to the cylinder. The end of the pressing block not connected to the piston rod extends freely. The support column, guide rod, and cylinder are all fixedly mounted on the base plate. This invention has a simple structure, reliable positioning, reduces labor intensity, and improves processing efficiency.

[0004] When using this fixture, the chips from gear machining fall into the interior of the fixture, making it inconvenient to clean the chips after machining. Furthermore, when fixing the gear, multiple parts need to be operated sequentially to clamp the inner ring of the gear, which is not only cumbersome but also results in uneven force on the surface of the gear being machined, leading to poor clamping and fixing effect.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example:

[0023] like Figure 1-4 As shown, this embodiment provides a gear insertion clamp, including a base 1, a support column 2 fixedly installed on the base 1, a support seat 3 fixedly installed on the support column 2, a hollow support member 4 fixedly installed on the support seat 3, a gear support ring 5 fixedly installed on the hollow support member 4, a processing gear 6 inserted into the gear support ring 5, an upper fixing ring 7 provided on the upper side of the processing gear 6, a lower fixing ring 8 provided on the lower side of the processing gear 6, contact pads 9 fixedly installed on both the upper fixing ring 7 and the lower fixing ring 8, a fixing ring positioning mechanism 10 provided on the hollow support member 4 and the upper fixing ring 7, and a fixing cylinder 11 fixedly installed on the support seat 3 and the lower fixing ring 8.

[0024] The gear 6 to be processed is inserted into the hollow support member 4. The gear support ring 5 provides stable support for the gear 6. The opening of the hollow support member 4 is then sealed by the fixing ring positioning mechanism 10, which positions the upper fixing ring 7 to prevent material debris from splashing into the hollow support member 4 during gear 6 processing. The fixing cylinder 11 is then activated. The extension of the fixing cylinder 11 causes the lower fixing ring 8 to move upwards. The lower fixing ring 8 then rests against the bottom of the gear 6, clamping and fixing the gear 6 through the upper and lower fixing rings 7 and 8. The large force-bearing area of ​​the upper and lower fixing rings 7 and 8 on the gear 6 provides more stable clamping. The contact pad 9 directly contacts the surface of the gear 6, further enhancing clamping stability. The process is simple and convenient for processing the gear 6. After processing, the gear 6 can be removed by simply pulling the upper fixing ring 7 upwards through the fixing ring positioning mechanism 10. The operation is quite convenient.

[0025] In this embodiment of the utility model, specifically, the fixed ring positioning mechanism 10 includes a baffle 101 disposed in the hollow support member 4, a connector 102 fixedly installed on the baffle 101 and the upper fixed ring 7, and a handle 103 fixedly installed on the baffle 101.

[0026] To seal the opening of the hollow support 4 and prevent machining debris from entering it, hold the handle 103 and place the baffle 101 inside the hollow support 4. The baffle 101 will seal the opening of the hollow support 4, preventing material debris from splashing into the hollow support 4 when machining the gear 6.

[0027] In this embodiment of the utility model, a support block 104 is fixedly installed inside the hollow support member 4, a miniature socket 105 is fixedly installed on the support block 104, a locking block 106 is movably installed inside the miniature socket 105, a locking plate 107 is fixedly installed at the bottom of the baffle 101, a spring 108 is fixedly installed on the miniature socket 105 and the locking block 106, and the locking plate 107 is locked onto the spring 108; a guide telescopic rod 109 is fixedly installed on the locking block 106, and the other end of the guide telescopic rod 109 is fixedly installed inside the miniature socket 105.

[0028] To achieve the positioning of the upper fixing ring 7, the clamping plate 107 is inserted into the front side of the micro socket 105. The clamping block 106 is squeezed and enters the micro socket 105. At this time, the spring 108 and the guide telescopic rod 109 will be compressed and shortened. The guide telescopic rod 109 will guide the movement of the clamping block 106, so that the clamping block 106 can only move back and forth within the micro socket 105. When the clamping hole on the clamping plate 107 coincides with the clamping block 106, the clamping block 106 will be driven into the clamping plate 107 under the action of the spring 108. The upper fixing ring 7 can then be pressed against the upper side of the gear 6 to be processed, thus achieving the positioning of the upper fixing ring 7.

[0029] In this embodiment of the utility model, a positioning insert plate 1010 is fixedly installed at the bottom of the baffle 101, and a positioning sleeve 1011 is fixedly installed on the micro socket 105, with the positioning insert plate 1010 inserted into the positioning sleeve 1011.

[0030] In order to guide the insertion of the card plate 107, the positioning insert 1010 is pre-aligned with the positioning sleeve 1011 and inserted, at which point the card plate 107 will be inserted into the front of the miniature socket 105.

[0031] In this embodiment of the utility model, a groove 1012 is provided on one side of the miniature socket 105, a lever 1013 is fixedly installed on the locking block 106, the lever 1013 is slidably installed in the groove 1012, and a blocking valve 1014 is provided on the baffle 101.

[0032] To facilitate the removal and unloading of the machined gear 6, after machining, the locking flap 1014 is inserted directly into the hollow support 4, and the lever 1013 is moved. The lever 1013 slides in the lever groove 1012, which can pull the locking block 106 into the miniature socket 105. Then, the upper fixing ring 7 can be pulled upwards to remove the machined gear 6. The operation is quite convenient.

[0033] In this embodiment of the utility model, the support base 3 is provided with a feeding hole 12, and a collection box 13 is fixedly installed on the base 1.

[0034] To collect the processed debris, during the processing of gear 6, the surrounding material debris falls onto the support base 3 and enters the collection box 13 through the discharge hole 12 on the support base 3. This reduces the dirt on the surface of the support base 3 caused by the processing debris and facilitates the collection of the processing debris.

[0035] Working principle: In use, insert the gear 6 to be processed into the hollow support 4. The gear support ring 5 will provide stable support for the gear 6. Then, hold the handle 103 and pre-align the positioning plate 1010 with the positioning sleeve 1011 and insert it. The baffle 101 can be placed inside the hollow support 4. At this time, the locking plate 107 will be inserted into the front of the micro socket 105. The locking block 106 will be squeezed and enter into the micro socket 105. At this time, the spring 108 and the guide telescopic rod 109 will press down. The shortening of the guide telescopic rod 109 guides the movement of the locking block 106, allowing the locking block 106 to move back and forth only within the micro socket 105. When the locking hole on the locking plate 107 coincides with the locking block 106, the locking block 106 will be driven into the locking plate 107 by the action of the spring 108. The upper fixing ring 7 can be pressed against the upper side of the gear 6 to be processed. The baffle 101 will block the opening of the hollow support 4 to prevent material debris from splashing into the hollow support 4 when processing the gear 6. Re-activating the fixing cylinder 11 causes it to extend, which in turn moves the lower fixing ring 8 upwards. The lower fixing ring 8 then rests against the underside of the processing gear 6. The upper fixing ring 7 and the lower fixing ring 8 clamp and fix the processing gear 6. The large force-bearing area of ​​the upper and lower fixing rings on the processing gear 6 ensures more stable clamping. The contact pad 9 directly contacts the surface of the processing gear 6, further enhancing clamping stability. The process is simple and convenient for processing the gear 6. Furthermore, during processing, surrounding material debris falls onto the support base 3 and is collected in the collection box 13 through the discharge hole 12 on the support base 3. This reduces dirt buildup on the support base 3 caused by processing debris and facilitates debris collection. After processing, the mesh valve 1014 is inserted directly into the hollow support 4, and the lever 1013 is moved. The lever 1013 slides in the lever groove 1012 to pull the locking block 106 into the miniature socket 105. Then, the upper fixing ring 7 is pulled upward to remove the processed gear 6. The operation is relatively convenient.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
