[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0045] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0046] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0049] 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.

[0050] like Figures 1-9As shown, a clamp for processing brake clamps is illustrated in one embodiment of the present invention, including a mounting base 1; a bridge plate 2 is rotatably mounted on the mounting base 1, and the bridge plate 2 is capable of vertically swinging so that the clamps on the first mounting surface 201 or the clamps on the second mounting surface 202 face upward; a quick-change module 3 is connected to the first mounting surface 201 and the second mounting surface 202 through at least two ball lock connectors 4; and a pressing component 5 is provided on the first mounting surface 201 and the second mounting surface 202, with at least one set on each, the pressing component 5 including at least two pressing swing arms 501 oscillatingly connected to the bridge plate 2 for pressing the clamps against the first mounting surface 201 or the second mounting surface 202.

[0051] In this embodiment, in order to solve the problem that the clamps in the related technology have limited compatibility and cannot be adapted to different specifications of fixing clamps, the first mounting surface 201 is facing upwards for the first processing step. After processing, the mounting base 1 is rotated so that the second mounting surface 202 faces upwards for the second processing step. After processing, when processing the next set of fixing clamps, if the fixing clamps cannot be effectively clamped in the existing quick-change module 3, the ball lock connector 4 can be disconnected and a suitable quick-change module 3 can be replaced to complete the clamping of different models of fixing clamps.

[0052] Specifically, after the bridge plate 2 and mounting base 1 are installed, the quick-change module 3 is placed on the mounting surface. The ball lock connector 4 is then installed to fix the quick-change module 3 onto the bridge plate 2. A clamping clamp is placed on the quick-change module 3, and the clamping clamp is pressed down by the pressure swing arm 501. The mounting base 1 rotates so that the two different mounting surfaces of the bridge plate 2 face upwards. When processing different clamping clamps, the ball lock connector 4 is disconnected, and the appropriate quick-change module 3 is removed and replaced to complete the clamping of the clamping clamp. This improves the compatibility of the fixture with different models of clamping clamps and saves on the production cost of multiple sets of fixtures.

[0053] Further as Figure 7 As shown, the first mounting surface 201 and the second mounting surface 202 have mounting grooves 204 for mounting the quick-change module 3, and the mounting grooves 204 are stepped; the ball lock seat 401 is embedded in the bottom wall of the mounting groove 204, and the top surface of the ball lock seat 401 is not higher than the first mounting surface 201 and the second mounting surface 202; the lock body 402 passes through the quick-change module 3 and is detachably connected to the ball lock seat 401, and is used to lock the quick-change module 3 in the mounting groove 204.

[0054] In this embodiment, the ball lock seat 401 is fixed in the mounting groove 204 by screws, and the quick-change module 3 is placed so that the through hole on the quick-change module 3 abuts against the mounting groove 204 concentrically. The lock body 402 abuts against the ball lock seat 401 through the through hole, and the lock body 402 and the ball lock seat 401 are fixedly connected by rotating the screw on the top of the lock body 402.

[0055] The use of ball locks facilitates the connection and disassembly of bridge plate 2 and different quick-change modules 3, making the assembly of the fixture more flexible and efficient, and also facilitating the inspection and maintenance of various parts of the fixture. When the fixture needs to be repaired, the quick-change module 3 can be easily and quickly removed, simplifying the fixture structure and improving the maintenance efficiency of the fixture.

[0056] Further as Figure 3 As shown, the quick-change module 3 includes a plate 301 disposed in the mounting groove 204; a limiting block 302 is provided on the plate 301 with a plurality of side edges for limiting the fixing clamp; a support base 303 is provided with at least two connected to the plate 301 for abutting against the fixing clamp to cooperate with the pressing component 5 to clamp the fixing clamp; a positioning pin 3031 is on the support base 303, extending perpendicular to the plate surface of the plate 301 for inserting into the positioning groove 6 of the fixing clamp and abutting against the bottom wall of the positioning groove 6.

[0057] In this embodiment, three limiting blocks 302 are arranged in an alternating pattern on the first mounting surface 201 plate 301, forming a space for placing the fixing clamp between the limiting blocks 302. The support base 303 is a conical block, also provided in three, arranged in a complementary and intersecting pattern with the limiting blocks 302. When placing the fixing clamp, the limiting blocks 302 initially limit the horizontal direction of the fixing clamp to prevent excessive deviation. The support base 303 is used to support the fixing clamp and reserve processing space. The positioning pin 3031 further restricts the horizontal direction of the fixing clamp, so that the fixing clamp is accurately located in the processing space. After the pressure arm 501 is pressed, the vertical movement of the fixing clamp is restricted.

[0058] The design of the limit block 302 and the positioning pin 3031 enhances the positioning effect of the entire fixture, avoids workpiece displacement caused by human error or adverse factors in the processing, and improves the fault tolerance of the fixture.

[0059] Further as Figure 5 As shown, the bridge plate 2 also includes a drive assembly 7 for driving the vertical swing of the pressure arm 501. The drive assembly 7 includes a telescopic member 701 fixed on the bridge plate 2, the telescopic member 701 having a fixed end and a telescopic end; and a connecting rod 702 for hinged to the telescopic end and the pressure arm 501.

[0060] In this embodiment, the fixed end of the telescopic member 701 is fixed to the bridge plate 2 with screws, and the top of the telescopic end is hinged to the end of the pressure swing arm 501 away from the quick-change module 3. One end of the connecting rod 702 is hinged to the fixed end of the telescopic member 701, and the other end is hinged to the pressure swing arm 501. When the telescopic end of the telescopic member 701 extends and retracts, it drives the swing arm to move. The connecting rod 702 provides support or tension to the end of the pressure swing arm 501 near the quick-change module 3 by swinging back and forth, so that the pressure swing arm 501 swings up and down within a specified range to tighten and loosen the fixing clamp.

[0061] Further as Figures 6-7As shown, the bridge plate 2 also includes an air detection assembly 8 for detecting the extension and retraction range of the telescopic component 701. The air detection assembly 8 includes an air detection block 801 fixedly connected to the extension and retraction end of the telescopic component 701. The air detection block 801 has a detection arc surface 8011 on one side. An air detection seat 802 connected to the bridge plate 2 is located on one side of the air detection block 801. The top of the air detection seat 802 has a spring contact 8021 for abutting against the detection arc surface 8011.

[0062] In this embodiment, the gas detection block 801 is fixed to the telescopic end of the telescopic member 701. The gas detection block 801 can move synchronously with the telescopic rod. During the movement, the relative position of the gas detection block 801 and the telescopic rod 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 moves vertically following the telescopic end, 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 203 inside the air detection seat 802 is closed, and the air pressure in the closed space is relatively 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 pressing arm 501 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 203 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 pressing arm 501 has not been pressed into place, and it is necessary to check whether the drive assembly 7 is faulty or whether the workpiece is placed in place.

[0063] The air detection component 8 boasts high reliability and stability, is less affected by environmental factors, and maintains good detection performance under various working environments, providing reliable detection results and reducing false positives and false negatives. It ensures the clamping clamp is reliably and stably secured to the fixture. The air detection component 8 can complete the inspection quickly, obtaining results in a short time, thus improving production efficiency. It helps to promptly identify faults or potential problems before processing, reducing the scrap rate.

[0064] Further as Figure 9 As shown, the bridge plate 2 has air passages 203 distributed inside. The air inlet 2031 is located on the second mounting surface 202 and is used to connect to the air source. The air outlet is located on the first mounting surface 201 and is used to connect to the air detection seat 802. The air passages 203 are built into the bridge plate 2 to make full use of space, making the overall structure of the fixture compact, reducing the fixture's footprint, and improving the utilization rate of the workspace.

[0065] Further as Figures 1-2 As shown, two quick-change modules 3 are provided on both the first mounting surface 201 and the second mounting surface 202.

[0066] By setting up two workstations on the same mounting surface, parallel operations can be achieved. For example, while processing the clamping clamp at one workstation, the other workstation can simultaneously clamp another clamping clamp. This reduces equipment investment and saves on equipment procurement costs and installation space. The two workstations are set up adjacent to each other on the same fixture, which facilitates operator management and improves labor efficiency.

[0067] Further as Figure 2 As shown, the end of the pressure arm 501 near the quick-change module 3 is also provided with two support arms 5011. The extended ends of the two support arms 5011 gradually extend towards opposite sides and respectively abut against the two fixing clamps.

[0068] In this embodiment, since the types of clamping clamps being processed are different, the areas requiring processing also differ. After the two individual pressing arms 501 clamp the clamping clamps, the pressing arms 501 will obstruct part of the processing surface, increasing the processing difficulty. Therefore, selecting pressing arms 501 with two support arms 5011 can create clearance space, and the two support arms 5011 ensure that the clamping clamps are subjected to uniform force, preventing movement during processing and improving the reliability and stability of the fixture.

[0069] 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.
