Description

Technical Field

[0001] This utility model relates to the field of gearbox mechanism side plate processing technology, specifically to a fixture for processing gearbox mechanism side plates. Background Technology

[0002] When using a transmission mechanism in mechanical equipment, a gearbox is often added to the outside of the transmission mechanism to protect it. Fixtures are used in the machining process of the gearbox core side plate.

[0003] Currently, the fixtures used for machining the side plates of gearbox cores mainly consist of a base plate and a manual clamping assembly mounted on the base plate. When using this type of fixture, the side plate to be machined is first placed on the base plate, and then the manual clamping assembly is operated step by step to clamp and limit the side plate. Although the fixture can clamp and limit the side plate, the manual clamping and limiting efficiency is relatively low. Furthermore, during the clamping and limiting process, the side plate is not effectively limited, which can easily cause the side plate to shift or skew relative to the machining station, resulting in poor limiting quality of the side plate. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a fixture for machining the movement side plate that has high clamping and limiting efficiency and can prevent the movement side plate from shifting or tilting between itself and the machining station after clamping and limiting.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a fixture for processing the side plate of a movement, including a base plate, a positioning platform reserved at the processing station on the base plate, and a limiting mechanism respectively provided at the four corners of the positioning platform. The limiting mechanism includes a pressure rod, a hinge frame and a cylinder, wherein the telescopic part of the cylinder is connected to one end of the pressure rod, the lower part of the pressure rod is connected to the hinge frame, and the hinge frame is connected to the top of the fixed part of the cylinder.

[0008] Furthermore, a side plate body is placed on the upper side of the positioning platform, and the lower side of the inner wall of the side plate body is in contact with the positioning platform.

[0009] By adopting the above technical solution, after the side plate body is placed at the positioning platform, the side plate body can be initially limited under the action of the positioning platform to prevent the side plate body from tilting and moving on the upper side of the base plate.

[0010] Furthermore, the positioning platform is bolted to the base plate, and the shape of the positioning platform matches the transverse cross-sectional shape within the side plate body.

[0011] By adopting the above technical solution, the shape of the positioning platform is matched with the transverse cross-sectional shape of the side plate body, which can ensure the rapid positioning of the side plate body after placement.

[0012] Furthermore, two sets of semi-cylindrical slots are symmetrically provided on both sides of the base plate, with two semi-cylindrical slots in each set.

[0013] By adopting the above technical solution, the external fixing bolts can be passed through the slot and locked, thus enabling the rapid installation and fixing of the base plate.

[0014] Furthermore, the pressure rod has a Z-shaped structure, and a U-shaped groove is provided on the part of the pressure rod that connects with the telescopic part of the cylinder.

[0015] By adopting the above technical solution, the U-shaped groove facilitates the convenient connection between the telescopic part of the cylinder and the pressure rod.

[0016] Furthermore, the bent portion on the lower side of the pressure rod is rotatably connected to the hinge frame.

[0017] By adopting the above technical solution, the rotating connection installation method makes it more convenient for the pressure rod to rotate relative to the hinge frame.

[0018] Furthermore, the bottom end of the hinge frame is bolted to the top end of the fixing part of the cylinder, and the rotating shaft on the hinge frame passes through the pressure rod.

[0019] By adopting the above technical solution, the bolt connection fixing method can ensure the reliable installation and use of the hinge frame on the cylinder.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] To address the current issue of fixtures used for machining gearbox gearbox side plates, which primarily consist of a base plate and a manual clamping assembly mounted on it, this type of fixture involves placing the gearbox side plate to be machined on the base plate and then gradually operating the manual clamping assembly to clamp and limit its movement. While this fixture structure can achieve clamping and limiting of the gearbox side plate, the manual clamping and limiting process is inefficient. Furthermore, because the gearbox side plate is not effectively restrained during clamping and limiting, it is prone to misalignment and skewness between the gearbox side plate and the machining station, resulting in the gearbox side plate... To address the issue of poor positioning quality, this invention installs a positioning mechanism consisting of a pressure rod, a hinge frame, and a cylinder at the machining station on the base plate. A positioning platform is pre-reserved at the machining station, allowing the fixture to initially position the side plate body under the action of the positioning platform. This prevents the side plate body from shifting or tilting relative to the machining station after clamping, ensuring the positioning quality of the side plate body. Simultaneously, by activating the cylinders in each positioning mechanism at the same time, the pressure rods in each mechanism are pressed synchronously onto the side plate body, avoiding the tedious manual tightening process and significantly improving the positioning efficiency of the side plate.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] like Figures 1-2As shown, a fixture for machining a side panel of a movement in this embodiment includes a base plate 3. A positioning platform 5 is reserved at the machining station on the base plate 3. A limiting mechanism 2 is provided at each of the four corners of the positioning platform 5. The limiting mechanism 2 includes a pressure rod 201, a hinge frame 202, and a cylinder 203. The telescopic part of the cylinder 203 is connected to one end of the pressure rod 201. The lower part of the pressure rod 201 is connected to the hinge frame 202. The hinge frame 202 is connected to the top of the fixed part of the cylinder 203. A side panel body 1 is placed on the upper side of the positioning platform 5. The lower side of the inner wall of the side panel body 1 is in contact with the positioning platform 5. After the side panel body 1 is placed on the positioning platform 5, it can be initially limited by the positioning platform 5 to prevent the side panel body 1 from tilting and moving on the upper side of the base plate 3. After the cylinder 203 in each limiting component drives the pressure rod 201 to rotate, it can quickly press and limit the side panel body 1 under the action of the pressure rod 201.

[0029] like Figures 1-2 As shown, in this embodiment, the positioning platform 5 is bolted to the base plate 3. The shape of the positioning platform 5 matches the transverse cross-sectional shape inside the side plate body 1, so that the shape of the positioning platform 5 matches the transverse cross-sectional shape inside the side plate body 1, which can ensure that the side plate body 1 is quickly positioned after placement. Two sets of semi-cylindrical slots 4 are also symmetrically opened on the two side walls of the base plate 3. There are two semi-cylindrical slots 4 in each set. The external fixing bolts are passed through the slots 4 and locked, which can realize the quick installation and fixing of the base plate 3.

[0030] like Figures 1-2 As shown, in this embodiment, the pressure rod 201 has a Z-shaped structure. A U-shaped groove is provided on the connection part of the pressure rod 201 with the telescopic part of the cylinder 203. The U-shaped groove facilitates the easy connection between the telescopic part of the cylinder 203 and the pressure rod 201. The bent part on the lower side of the pressure rod 201 is rotatably connected to the hinge frame 202. The rotatable connection makes the rotation of the pressure rod 201 relative to the hinge frame 202 more convenient. The bottom end of the hinge frame 202 is bolted to the top end of the fixed part of the cylinder 203. The rotating shaft on the hinge frame 202 passes through the pressure rod 201. The bolted connection ensures the reliable installation and use of the hinge frame 202 on the cylinder 203.

[0031] The specific implementation process of this embodiment is as follows: When in use, the base plate 3 is first installed on the corresponding processing table of the processing equipment. Then, the cylinder 203 in the limiting assembly is connected to the start control component on the equipment, and then the fixture can be put into use. During use, a limiting mechanism 2 consisting of a pressure rod 201, a hinge frame 202 and a cylinder 203 is installed at the processing station on the base plate 3, and a positioning table 5 is reserved in advance at the processing station. When the fixture is in use, it can initially limit the side plate body 1 under the action of the positioning table 5, so as to avoid the side plate body 1 from shifting or tilting relative to the processing station after clamping, and ensure the limiting quality of the side plate body 1. At the same time, by activating the cylinders 203 in each limiting mechanism 2 at the same time, the pressure rods 201 in each limiting mechanism 2 are pressed onto the side plate body 1 synchronously, avoiding the tedious operation of manual step-by-step pressing, and significantly improving the limiting efficiency of the side plate body.
