They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0051] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0052] like Figures 1-8As shown, a fixture for machining a front caliper body of an automobile is provided in one embodiment of the present invention, including a mounting base 1; the mounting base 1 has a bridge plate 2 for mounting the fixture; a limiting rod 701 is disposed on the bridge plate 2, and the limiting rod 701 is used to limit the side edge of the front caliper body; at least two pressure plates 3 are oscillatingly disposed on the bridge plate 2, and the pressure plates 3 are used to position and press the front caliper body onto the bridge plate 2; a side push assembly 4 is disposed on the bridge plate 2, located between the two pressure plates 3; a side positioning block 401 is disposed on the bridge plate 2, located between the side push assembly 4 and one pressure plate 3, and the side positioning block 401 is used to cooperate with the side push assembly 4 to clamp the front caliper body.

[0053] In this embodiment, in order to solve the technical problems of poor positioning accuracy and uneven clamping force of the clamp in the related art, a limiting rod 701 is provided on the bridge plate 2. The limiting rod 701 abuts against the side edge of the front clamp body to restrict the movement of the front clamp body in the horizontal direction. Furthermore, a side push assembly 4 and a side positioning block 401 are provided between the pressure plates. The pressure plates are used to abut against the upper surface of the front clamp body to clamp the front clamp body on the bridge plate 2 in the vertical direction. The side push assembly 4 and the side positioning block 401 abut against the vertical surface of the front clamp body to clamp the front clamp body in the horizontal direction.

[0054] Specifically, the front clamp body is placed between the limiting rods 701, the side positioning block 401 abuts against one vertical surface of the front clamp body, and the side push assembly 4 is located at the hollowed-out part in the middle of the front clamp body. The side push assembly 4 moves horizontally towards the side positioning block 401 and abuts against the vertical surface of the hollowed-out part, clamping the front clamp body horizontally. The swinging pressure plate 3 abuts against the upper surface of the front clamp body, clamping the front clamp body vertically. By setting the limiting rods 701, the horizontal displacement of the front clamp body is initially limited. Further, the side push assembly 4, the side positioning block 401, and the pressure plate 3 clamp the front clamp body in both horizontal and vertical directions, ensuring precise positioning while ensuring uniform force on the front clamp body in both horizontal and vertical directions.

[0055] Further as Figures 2-3 As shown, the side push assembly 4 includes a side push seat 402 connected to the bridge plate 2; a first side push slider 403 and a second side push slider 404, the first side push slider 403 being vertically slidably disposed within the side push seat 402, and the second side push slider 404 being horizontally slidably disposed within the side push seat 402, the second side push slider 404 being used to clamp the front clamp body; wherein, both the first side push slider 403 and the second side push slider 404 have sliding inclined surfaces 405 and slide against each other, within the side push seat 402, the first side push slider 403 pushes the second side push slider 404 to move horizontally through the sliding inclined surfaces 405; a side push pin 4041 is disposed on the second side push slider 404, the second side push slider 404 clamping the front clamp body through the side push pin 4041.

[0056] In this embodiment, the side push seat 402 is fixed on the bridge plate 2, the second side push slider 404 is horizontally slidably connected to the side push seat 402, and the first side push slider 403 is vertically slidably connected to the side push seat 402. During installation, the sliding inclined surfaces 405 of the second side push slider 404 and the first side push slider 403 are in contact. The side push pin 4041 is fixed to one end of the second side push slider 404 and is used to abut against the vertical surface of the front clamp to clamp the front clamp.

[0057] Specifically, the first side push slider 403 is L-shaped and has three vertical surfaces. Two of these vertical surfaces slide against the inner wall of the side push seat 402, ensuring that the first side push slider can slide vertically. The second side push slider 404 has a hole with the same vertical inclination angle as the first side push slider 403. The first side push slider 403 passes through this inclined hole. During movement, the sliding inclined surfaces 405 of the two side push sliders interact with each other, pushing the second side push slider 404 to move horizontally. The side push pin 4041 abuts against the vertical surface of the front clamp body, clamping the front clamp body under the pushing force of the first side push slider 403. The side push sliders convert vertical movement into horizontal movement through a simple mechanical structure, thereby fulfilling the requirement of clamping the front clamp body horizontally.

[0058] Further as Figure 1 As shown, the pressure plate 3 includes a first pressure plate 301 and a second pressure plate 302. The first pressure plate 301 is away from the side positioning block 401, and the second pressure plate 302 is close to the side positioning block 401. A detachable quick-change pressure block 3021 perpendicular to the second pressure plate 302 is provided on the end of the second pressure plate 302 away from the bridge plate 2. The quick-change pressure block 3021 is used to abut against the concave surfaces on both sides of the front clamp body.

[0059] In this embodiment, after the front clamp body is placed, the first pressure plate 301 and the second pressure plate 302 swing. The first pressure plate 301 has a downwardly curved pressure block at the end away from the bridge plate 2, which abuts against the horizontal surface above the front clamp body. The second pressure plate 302 has a quick-change pressure block 3021 connected to the end away from the bridge plate 2 by screws. The quick-change pressure block 3021 has a convex arc surface that abuts against the concave arc surfaces of the front clamp body, clamping and positioning the front clamp body at the same time. There are many models of front clamp bodies with complex structures and irregular shapes. The quick-change pressure block 3021 can be matched with the surface of the front clamp body by replacing the quick-change pressure block 3021 without changing the clamps or disassembling the pressure plate 3, so as to achieve the best positioning and clamping effect.

[0060] Further as Figures 3-5As shown, the bridge plate 2 also includes a telescopic member 5 fixed on the bridge plate 2. The telescopic member 5 is used to drive the first pressure plate 301 and the second pressure plate 302 to swing. The first pressure plate 301 has a hinge hole for hinged with the bridge plate 2 and a quick-change groove for connecting with the telescopic member 5 at one end near the bridge plate 2. The second pressure plate 302 has hinge holes for hinged with the bridge plate 2 and the telescopic member 5 respectively at one end near the bridge plate 2. The first side push slider 403 is fixedly connected to the telescopic member 5.

[0061] In this embodiment, the telescopic member 5 has several telescopic ends. The first pressure plate 301 and the second pressure plate 302 are respectively connected to the telescopic member 5. The telescopic member 5 moves in the vertical direction, causing the first pressure plate 301 and the second pressure plate 302 to swing within a certain range to abut against the surface of the front clamp body. The first pressure plate 301 is detachably connected to the telescopic end of the telescopic member 5. When replacing different models of front clamp bodies, the first pressure plate 301 can be replaced to match the front clamp body, which improves the compatibility of the clamp with different front clamp bodies and reduces the procurement cost of the clamp. The telescopic end of the telescopic member 5 is fixedly connected to the first side push slider 403. The telescopic member 5 moves in the vertical direction, causing the first side push slider 403 to slide in the vertical hole of the side push seat 402 and push the second side push slider 404 to move horizontally, thereby clamping the front clamp body in the horizontal direction.

[0062] Further as Figure 1 and Figure 7 As shown, the bridge plate 2 has a first mounting surface 201 for mounting the front clamp body in the forward direction and a second mounting surface 202 for mounting the front clamp body in the reverse direction. The pressure plate 3 and the side push assembly 4 are located on the first mounting surface 201. It also includes a pressure swing arm 6, which is oscillatingly disposed on the second mounting surface 202. The pressure swing arm 6 is used to clamp the front clamp body.

[0063] In this embodiment, the bridge plate 2 is rotatably mounted on the mounting base 1. The bridge plate 2 can swing vertically so that the front clamp on the first mounting surface 201 or the front clamp on the second mounting surface 202 faces upward. There is one abutting swing arm 6, which is mounted on the second mounting surface 202. By rotating the bridge plate 2 onto the mounting base 1, two processing steps can be completed on the same fixture, which improves the space utilization of the fixture.

[0064] Further as Figure 6 As shown, the bridge plate 2 also includes a plate body 7, at least one of which is detachably provided on the first mounting surface 201 and the second mounting surface 202. A limiting rod 701 and a side positioning block 401 are located on the plate body 7. A ball lock seat 702 is embedded in the bridge plate 2. A lock body 703 is disposed through the plate body 7 and detachably connected to the ball lock seat 702 for locking the plate body 7 onto the bridge plate 2. The design of the plate body 7 modularizes the machining station of the front clamp body. When machining different front clamp bodies, only the appropriate plate body 7 needs to be replaced to achieve precise positioning and provide reliable and stable clamping force.

[0065] In this embodiment, the plate body 7 is provided with two on the first mounting surface 201 and the second mounting surface 202. The plate body 7 on the first mounting surface 201 has a limiting rod 701, which is located on the side close to the first pressure plate 301. The plate body 7 on the first mounting surface 201 also has a side positioning block 401, which is located between the side push assembly 4 and a pressure plate 3. The plate body 7 is detachably connected to the bridge plate 2 through the ball lock seat 702 and the lock body 703.

[0066] Further as Figure 6 As shown, the plate body 7 includes at least two support seats 704. The support seats 704 are connected to the plate body 7 and are used to abut against the front clamp body to cooperate with the pressure plate to clamp the front clamp body.

[0067] In this embodiment, three support seats 704 are provided on the first mounting surface 201, two of which are located between the first pressure plate 301 and the limiting rod 701, and the other is provided on the side positioning block 401. The support seat 704 abuts against the bottom plane of the front clamp body and is used to support the front clamp body and reserve processing space.

[0068] Further as Figure 7 As shown, the plate body 7 also includes: a vertical plate 705 disposed on the plate body 7 of the second mounting surface 202 for contacting the vertical surface of the front clamp body.

[0069] In this embodiment, the upright plate 705 is vertically mounted on the plate 7 on the second mounting surface 202, located on the side close to the telescopic member 5. The vertical surface of the front clamp body abuts against the upright plate 705, and the pressing swing arm 6 on the second mounting surface 202 swings to clamp the front clamp body.

[0070] Further as Figure 8 As shown, the bridge plate 2 is also provided with an air detection assembly 8 for detecting the extension and retraction range of the telescopic component 5. The air detection assembly 8 includes: an air detection block 801, which is fixedly connected to the pressure plate 3, and has a detection arc surface 8011 on one side; and an air detection seat 802, which is connected to the bridge plate 2 and located on one side of the air detection block 801. The top of the air detection seat 802 is provided with a spring contact 8021 for contacting the detection arc surface 8011.

[0071] In this embodiment, the gas detection block 801 is fixed on one side of the pressure plate 3. The gas detection block 801 can move synchronously with the pressure plate. During the movement, the relative position of the gas detection block 801 and the pressure plate does not change. The gas detection block 801 has a protruding detection arc surface 8011 with a semi-circular cross section. The gas detection seat 802 is located on one side of the detection arc surface 8011. The gas detection assembly 8 is connected to an instrument for detecting changes in air pressure inside the gas detection seat 802. When the air detection block 801 swings with the pressure plate, it detects the contact between the arc surface 8011 and the spring contact 8021. When the most convex point of the arc surface contacts the spring contact 8021, the air passage inside the air detection seat 802 is closed, and the air pressure in the closed space is stable within the set range. After the instrument detects that the air pressure is within the set range, the green light on the fixture lights up, indicating that the pressure plate 3 has been pressed into place and processing can proceed. Conversely, if the spring contact 8021 does not contact the most convex point of the arc surface, the air passage inside the air detection seat 802 cannot be completely closed, and the air pressure in the passage deviates significantly from the set range. After the instrument detects that the air pressure is not within the set range, the red light on the fixture lights up, indicating that the pressure plate 3 has not been pressed into place. It is necessary to check whether the telescopic component 5 is faulty or whether the workpiece is placed in place.

[0072] The air inspection component 8 boasts high reliability and stability, is less affected by environmental factors, and maintains good inspection performance under various working environments, providing reliable inspection results and reducing false positives and false negatives. It ensures the front clamp is reliably and stably clamped onto the fixture. The air inspection component 8 can complete inspection quickly, obtaining results in a short time, thus improving production efficiency. It helps to promptly identify faults or potential problems before processing, reducing scrap rates.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
