Description
Technical Field
[0001] This utility model belongs to the technical field of parts processing equipment, and in particular relates to a positioning fixture for grinding the front end cover. Background Technology
[0002] The front cover is a core assembly component of power equipment such as engines and motors. The flatness and roughness of its end face, edges, and assembly surfaces directly affect the sealing performance, transmission accuracy, and service life of the equipment. Traditional front cover grinding often relies on manual hand-held positioning, which has problems such as unstable clamping and large positioning reference deviations. This can easily lead to uneven grinding thickness and dimensional deviations. Moreover, manual operation is inefficient and labor-intensive, making it difficult to meet the consistency requirements of large-scale production. As the manufacturing industry transforms towards high precision and automation, there is an urgent need for a dedicated positioning fixture to achieve rapid clamping and precise positioning of the front cover, reduce human error, ensure grinding accuracy and stability, improve production efficiency, reduce labor costs, and adapt to the operational needs of modern production lines.
[0003] However, existing positioning fixtures for grinding often fix the parts directly with clamps during use. This means that when changing surfaces later, the two clamps need to be completely separated. At this time, the parts will fall directly from the clamps, which can easily cause collisions and damage, thus increasing production costs. Utility Model Content
[0004] The purpose of this utility model is to provide a positioning fixture for grinding the front end cover. By setting a pre-clamping part, it solves the problem that existing positioning fixtures for grinding often fix the parts directly by clamping plates during use, which means that when changing the surface later, the two clamping plates need to be completely separated. At this time, the parts will fall directly from the clamping plates, which is prone to collision and damage, thereby increasing production costs.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a positioning fixture for grinding a front end cap, including a bracket, and further including: a positioning part disposed within the bracket; a pre-clamping part installed within the bracket; a locking part located above the bracket; the pre-clamping part includes a fixing component installed within the bracket; and a pressing component disposed above the bracket; the fixing component includes a clamping plate two fixedly connected to the inner wall of the bracket; a clamping block is disposed on the right side of the clamping plate two; a connecting block one is fixedly connected to the left side of the clamping block; the outer wall of the connecting block one is slidably connected to the clamping plate two; the outer wall of the connecting block one is slidably connected to the clamping plate two; the outer wall of the connecting block two is slidably connected to the clamping plate two; a spring one is disposed within the connecting block two; the side of the spring one closest to the connecting block two is fixedly connected to the connecting block two; and the side of the spring one closest to the connecting block one is fixedly connected to the connecting block one.
[0007] Furthermore, the positioning part includes a clamping plate slidably connected to the inner wall of the bracket 1. A threaded rod is rotatably connected to the right side of the clamping plate 2. The right side of the threaded rod extends to the outside of the bracket 1 and passes through the clamping plate 1. The outer wall of the threaded rod is threadedly connected to the clamping plate 1. A motor is fixedly connected to the right side of the bracket 1. The output shaft of the motor is fixedly connected to the threaded rod through a coupling. Two telescopic protective sleeves are fitted on the outer wall of the threaded rod. The sides of the two telescopic protective sleeves that are close to each other are fixedly connected to the clamping plate 1. The side of the telescopic protective sleeve on the left side that is close to the clamping plate 2 is fixedly connected to the clamping plate 2, and the side of the telescopic protective sleeve on the right side that is away from the clamping plate 1 is fixedly connected to the bracket 1.
[0008] Furthermore, the locking part includes a buckle assembly disposed on the clamping plate two; and an unlocking assembly installed on the left side of the clamping plate two, the unlocking assembly being used to unlock the buckle assembly.
[0009] Furthermore, the extrusion assembly includes a limiting groove formed in the inner wall of the clamping plate two, an extrusion block is slidably connected to the inner wall of the limiting groove, a rotating shaft is rotatably connected to the inner wall of the clamping plate two, a transmission component is provided inside the extrusion block, the shape of the extrusion block is adapted to the connecting block two, the transmission component includes a rack fixedly connected to the inner wall of the extrusion block, and a gear is fixedly connected to the outer wall of the rotating shaft, the gear meshing with the rack.
[0010] Furthermore, the buckle assembly includes a handle one fixedly connected to the outer wall of the rotating shaft, a bracket two fixedly connected to the right side of the handle one, a buckle component provided on the clamping plate two, the buckle component including a chuck fixedly connected to the left side of the clamping plate two, and a locking tooth fixedly connected to the right side of the limiting rod, the shape of the locking tooth being adapted to the chuck.
[0011] Furthermore, the unlocking component includes a limiting rod disposed within the bracket two, a handle two slidably connected to the inner wall of the bracket two, the limiting rod passing through the handle two, the outer wall of the limiting rod slidably connected to the handle two, a connecting plate fixedly connected to the left side of the limiting rod, a spring two fixedly connected to the left side of the connecting plate, and the left side of the spring two fixedly connected to the bracket two.
[0012] This utility model has the following beneficial effects:
[0013] 1. By setting a pre-clamping part, when clamping, the clamping block is squeezed by the part and drives the connecting block one to slide into the connecting block two. The spring one is compressed accordingly. The extrusion assembly drives the extrusion block to slide in the limiting groove through the transmission component. The extrusion block squeezes the connecting block two and moves it towards the connecting block one, allowing the spring one to be further compressed. After adjusting the clamping position of the part, the part can be pre-clamped first and then fixed. When the part is released on the other side, it can also be clamped on the clamping plate and can be directly removed, so that the part will not fall directly, thereby reducing the economic loss caused by the collision of the part.
[0014] 2. By setting a locking part, when the handle is turned, the limit rod rotates around the shaft through the bracket two. The locking teeth press against the chuck, and the limit rod slides inside the handle two and presses against the spring two through the connecting plate. After the rotation stops, the locking teeth are engaged in the chuck under the action of the spring two. When the handle two of the unlocking component is pulled, it causes the connecting plate to slide inside the bracket two, and the locking teeth move away from the chuck, thereby reversing the handle one. This can lock the shaft after the handle is turned, preventing it from reversing during the subsequent processing and grinding of parts, thus ensuring the stable operation of the device.
[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] It should be noted that the control of motor 104 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be set using existing technologies, such as PLC.
[0032] A specific application of this embodiment is as follows: In use, the motor 104 can be started, causing its output shaft to drive the clamping plate 102 to slide via the threaded rod 103. The front surface of the clamping plate 102 is the area where the part is placed. The part can then be inserted between the clamping plate 102 and the clamping block 212. At this time, the clamping block 212 will be compressed by the part, causing the connecting block 213 to slide into the connecting block 214. The spring 215 will then compress and generate elastic force. At this point, the handle 3 can be turned clockwise. 11. This causes the rotating shaft 223 to drive the gear 225 to rotate. When the gear 225 rotates, it drives the pressing block 222 to slide within the limiting groove 221 via the rack 224. At this time, the pressing block 222 will press the connecting block 214, causing it to move towards the connecting block 213. This will further compress the spring 215 and generate elastic force. When the connecting block 214 and the connecting block 213 are fully engaged, the clamping block 212 will clamp the part under the action of the elastic force of the spring 215. During the operation of handle 311, handle 311 drives limit rod 321 to rotate around shaft 223 via bracket 312, thereby causing cleat 314 to press against chuck 313. At this time, under the action of chuck 313, limit rod 321 slides within handle 322, thereby compressing spring 324 via connecting plate 323, causing it to compress and generate elastic force. When handle 311 stops rotating, the elastic force of spring 324 causes cleat 314 to engage with chuck 313. Under the action of chuck 313, the rotating shaft 223 will be prevented from reversing. When unlocking is required, handle 2 322 can be pulled to drive the connecting plate 323 to slide inside bracket 2 312, thereby driving the locking tooth 314 away from chuck 313. At this time, handle 1 311 can be reversed to drive the rotating shaft 223 to reverse, thereby releasing the clamping block 212. At this time, under the compression of spring 1 215, the part will be prevented from falling directly. Then the part can be removed, turned over, and then fixed in the same way.
