Description

Technical Field

[0001] This utility model relates to the technical field of alloy hammer head processing equipment, and in particular to a positioning fixture for alloy hammer head processing. Background Technology

[0002] The positioning fixture for alloy hammer head machining is an auxiliary device specifically designed for the alloy hammer head machining process. Its main function is to accurately and stably fix the alloy hammer head in the preset machining position through a specific structural design and positioning components. This ensures that the hammer head maintains the predetermined spatial posture and positional accuracy during machining processes such as cutting, grinding, and drilling, providing a reliable reference for the machining equipment. This ensures that the machining dimensions and geometric tolerances meet the design requirements, while reducing machining errors and quality defects caused by hammer head displacement or vibration during the machining process.

[0003] In actual grinding operations, although the existing positioning fixture can achieve stable fixation of the hammer, its structural design has obvious limitations: the fixture body is large in size and the contact position with the hammer is not reasonably distributed, which seriously hinders the movement trajectory of the grinding wheel, robotic arm and other execution components of the grinding equipment during the grinding process. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing positioning fixtures occupy the processing space required by the grinding equipment when grinding the surface of the hammer head, thus preventing the grinding equipment from fully grinding the hammer head. Therefore, a positioning fixture for processing alloy hammer heads is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a positioning fixture for machining alloy hammer heads, comprising a positioning platform, with a first end positioning component and a second end positioning component respectively provided at both ends of the positioning platform. The second end positioning component includes a positioning frame, a second end positioner, and an adjusting shaft. One end of the adjusting shaft movably passes through the interior of the positioning frame and is connected to the interior of the second end positioner via a transmission connection. The second end positioner includes a positioning chamber, a transmission gear, a transmission rack, a transmission plate, and a pressure plate. The transmission gear is rotatably connected to the center of the positioning chamber. The transmission gear meshes with two transmission racks. The two transmission racks are fixedly connected to one side of the transmission plate. One end of the transmission plate is fixedly connected to one side of the pressure plate. A push positioning component is provided on one side of the second end positioning component.

[0006] Preferably, a rotating ring is fixedly connected to the other end of the adjusting shaft, and a lever is symmetrically fixedly connected to the outer side of the rotating ring.

[0007] Preferably, an adjusting positioning ring is fixedly connected to one side of the positioning frame, a positioning ring is slidably connected to the outer side of the adjusting positioning ring, and a positioning plate is symmetrically fixedly connected to one side of the positioning ring.

[0008] Preferably, a slider is fixedly connected to the bottom end of the positioning frame, and a slide rail is slidably connected to the bottom end of the slider, with the slide rail fixedly installed on the top surface of the positioning platform.

[0009] Preferably, the push positioning component includes a threaded rod, an adjusting block, and two bases. One end of the threaded rod is threadedly connected to the inside of the adjusting block, the adjusting block is fixedly connected to one side of the slider, and the threaded rod movably passes through the inside of the two bases.

[0010] Preferably, the first end positioning component includes a support frame and a first end positioner, one end of the first end positioner is rotatably connected to one end of the support frame, and the other end of the first end positioner is symmetrically provided with positioning grooves.

[0011] Preferably, the positioning chamber has through holes on both sides, and the transmission plate moves through the interior of the through holes.

[0012] Preferably, guide rods are symmetrically fixedly installed inside the positioning chamber. The guide rods are located on one side of the through hole, and one end of the guide rods movably passes through one end of the transmission plate on the other side.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the hammer head to be processed is positioned and clamped at both ends by the No. 1 end positioning component and the No. 2 end positioning component respectively. When the end of the hammer head needs to be ground, the corresponding No. 1 end positioning component or the No. 2 end positioning component releases the positioning clamp, while the other positioning component provides stable support for the hammer head, ensuring that the hammer head will not deviate during the grinding process, and at the same time reserving sufficient grinding operation space for the grinding equipment.

[0015] 2. In this utility model, the rigid contact between the positioning plate and the lever plate can form a reliable anti-reverse constraint, preventing the adjusting shaft from shifting due to external force or vibration, and ensuring that the second end positioner maintains a stable position on the other end of the hammer head for a long time.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-5As shown, this utility model provides a positioning fixture for machining alloy hammer heads, including a positioning table 1. A first end positioning assembly 2 and a second end positioning assembly 3 are respectively provided at both ends of the positioning table 1. The second end positioning assembly 3 includes a positioning frame 31, a second end positioner 32, and an adjusting shaft 33. One end of the adjusting shaft 33 movably passes through the interior of the positioning frame 31 and is connected to the interior of the second end positioner 32. The second end positioner 32 includes a positioning chamber 321, a transmission gear 322, a transmission rack 323, a transmission plate 324, and a pressure plate 325. The transmission gear 322 is rotatably connected to the center inside the positioning chamber 321. The transmission gear 322 meshes with two transmission racks 323, which are fixedly connected to one side of the transmission plate 324. One end is fixedly connected to one side of the pressure plate 325. A push positioning component 4 is provided on one side of the second end positioning component 3. A slider 314 is fixedly connected to the bottom end of the positioning frame 31. A slide rail 315 is slidably connected to the bottom end of the slider 314. The slide rail 315 is fixedly installed on the top surface of the positioning platform 1. The push positioning component 4 includes a threaded rod 41, an adjusting block 42 and two bases 43. One end of the threaded rod 41 is threadedly connected to the inside of the adjusting block 42. The adjusting block 42 is fixedly connected to one side of the slider 314. The threaded rod 41 moves through the inside of the two bases 43. The first end positioning component 2 includes a support frame 21 and a first end positioner 22. One end of the first end positioner 22 is rotatably connected to one end of the support frame 21. The other end of the first end positioner 22 is symmetrically provided with positioning grooves 221.

[0025] The specific settings and functions of this embodiment are described below. The hammerhead to be processed is positioned and clamped at both ends by the first end positioning component 2 and the second end positioning component 3, respectively. When grinding is required at the end of the hammerhead, the corresponding first end positioning component 2 or second end positioning component 3 releases the positioning clamp, and the other positioning component provides stable support for the hammerhead, ensuring that the hammerhead will not shift during grinding, while reserving sufficient grinding operation space for the grinding equipment. The positioning groove 221 in the first end positioning component 2 is engaged with the positioning rod at one end of the hammerhead to stably fix the hammerhead; the second end positioning component... When component 3 positions and clamps the other end of the hammer head, the threaded rod 41 is rotated, which drives the adjusting block 42 to move. Under the transmission of the adjusting block 42, the slider 314 slides on the outside of the slide rail 315, thereby driving the positioning frame 31 to move towards the other end of the hammer head. One end of the second end positioner 32 enters the groove at the other end of the hammer head. Then, the adjusting shaft 33 is rotated, which drives the transmission gear 322 to rotate. Under the transmission of the transmission rack 323, the transmission gear 322 drives the two transmission plates 324 to move in opposite directions, so that the two pressure plates 325 position and squeeze the inner wall of the groove at the other end of the hammer head, thus stably positioning the other end of the hammer head.

[0026] Example 2: Figures 1-5 As shown, the positioning fixture for machining alloy hammer heads in this utility model includes a positioning table 1. A first end positioning component 2 and a second end positioning component 3 are respectively installed at both ends of the positioning table 1. The second end positioning component 3 includes a positioning frame 31, a second end positioner 32, and an adjusting shaft 33. One end of the adjusting shaft 33 movably passes through the interior of the positioning frame 31 and is connected to the interior of the second end positioner 32. The second end positioner 32 includes a positioning chamber 321, a transmission gear 322, a transmission rack 323, a transmission plate 324, and a pressure plate 325. The transmission gear 322 is rotatably connected to the center of the positioning chamber 321. The transmission gear 322 meshes with two transmission racks 323, which are fixedly connected to one side of the transmission plate 324. One end of the positioning frame 321 is fixedly connected to one side of the pressure plate 325. A push positioning component 4 is provided on one side of the second end positioning component 3. A rotating ring 331 is fixedly connected to the other end of the adjusting shaft 33. A lever 332 is symmetrically fixedly connected to the outer side of the rotating ring 331. An adjusting positioning ring 311 is fixedly connected to one side of the positioning frame 31. A positioning ring 312 is slidably connected to the outer side of the adjusting positioning ring 311. A positioning plate 313 is symmetrically fixedly connected to one side of the positioning ring 312. Through holes 326 are opened on both sides of the positioning chamber 321. A transmission plate 324 is movably inserted through the inside of the through hole 326. A guide rod 327 is symmetrically fixedly installed inside the positioning chamber 321. The guide rod 327 is located on one side of the through hole 326. One end of the guide rod 327 is movably inserted through the other end of the transmission plate 324.

[0027] The overall effect of this embodiment is that after the adjusting shaft 33 completes the rotational adjustment of the transmission gear 322, it drives the positioning ring 312 to slide towards the dial plate 332, so that the positioning plate 313 on one side of the positioning ring 312 abuts against the outside of the dial plate 332, positioning the adjusting shaft 33 and preventing it from reversing. This ensures that the second end positioner 32 can stably position the other end of the hammer. Through the rigid contact between the positioning plate 313 and the dial plate 332, a reliable anti-reversal constraint can be formed, preventing the adjusting shaft 33 from shifting position due to external force or vibration, and ensuring that the second end positioner 32 can stably position the other end of the hammer. The end positioner 32 maintains a stable position on the other end of the hammer head for a long period of time. When the transmission plate 324 passes through the through hole 326, the guide rod 327 constrains the movement trajectory of the transmission plate 324, so that the transmission plate 324 can pass through the through hole 326 perpendicularly, ensuring that the pressure plate 325 can be stably attached to the inner wall of the groove at the other end of the hammer head. The rigid constraint of the guide rod 327 on the movement trajectory of the transmission plate 324 can effectively eliminate lateral offset during the transmission process, ensure that the fit between the pressure plate 325 and the inner wall of the groove of the hammer head is controlled within the preset tolerance range, and reduce processing vibration caused by the fit gap.

[0028] The device is used and works as follows: The hammerhead to be processed is positioned and clamped at both ends by the No. 1 end positioning component 2 and the No. 2 end positioning component 3 respectively. When the end of the hammerhead needs to be ground, the corresponding No. 1 end positioning component 2 or No. 2 end positioning component 3 is released from the positioning clamp, and the other positioning component provides stable support for the hammerhead to ensure that the hammerhead will not deviate during the grinding process, while reserving sufficient grinding operation space for the grinding equipment.

[0029] The positioning groove 221 in the first end positioning assembly 2 engages with the positioning rod at one end of the hammer head to stabilize and fix the hammer head. When the second end positioning assembly 3 positions and clamps the other end of the hammer head, the threaded rod 41 is rotated, which drives the adjusting block 42 to move. Under the transmission of the adjusting block 42, the slider 314 slides on the outside of the slide rail 315, thereby driving the positioning frame 31 to move towards the other end of the hammer head. One end of the second end positioner 32 enters the groove at the other end of the hammer head. Then, the adjusting shaft 33 is rotated, which drives the transmission gear 322 to rotate. Under the transmission of the transmission rack 323, the transmission gear 322 drives the two transmission plates 324 to move in opposite directions, so that the two pressure plates 325 position and squeeze the inner wall of the groove at the other end of the hammer head, thus stabilizing the other end of the hammer head.

[0030] After the adjusting shaft 33 completes the rotation adjustment of the transmission gear 322, it drives the positioning ring 312 to slide towards the dial plate 332, so that the positioning plate 313 on one side of the positioning ring 312 abuts against the outside of the dial plate 332 to position the adjusting shaft 33 and prevent it from reversing.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
