It involves pressing the steel plate into a specific angle or arc using cold or hot pressing to facilitate subsequent processing. To ensure processing accuracy during bending, the steel plate needs to be positioned to prevent it from wobbling and affecting the precision. Existing clamping fixtures typically apply pressure to the center of a clamping plate using a cylinder or motor to press the plate against the steel plate during processing, thus fixing the plate in place.

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] In the description of this utility model, it should be understood that the terms "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not 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.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] like Figures 1 to 4As shown, a clamping fixture of this utility model includes, The system comprises a base 1, a support frame 2, a clamping assembly 3, and a locking assembly 4. The base 1 has a clamping area on its top surface. The support frame 2 is located on the top surface of the base 1. The clamping assembly 3 includes a clamping plate 31 and a clamping actuator 32. The clamping plate 31 is located above the clamping area and has a locking hole 311 extending vertically. The clamping actuator 32 is mounted on the support frame 2 and connected to the clamping plate 31. The clamping actuator 32 drives the clamping plate 31 to move vertically to a first position and a second position. The locking assembly 4 includes a locking member 41, which corresponds to the locking hole 311 and protrudes from the top surface of the base 1. When the clamping plate 31 moves to the first position, it is located above the locking member 41. When the clamping plate 31 moves to the second position, the locking member 41 is engaged with the locking hole 311.

[0024] In the above technical solution, the top surface of the base 1 is provided with a pressing area, and a steel plate is placed on the pressing area for fixing by the pressing assembly 3. The support frame 2 is set on the base 1 to support the pressing assembly 3. The pressing driver 32 of the pressing assembly 3 is connected to the pressing plate 31 so that the pressing plate 31 can move vertically to the first position and the second position. The locking member 41 of the locking assembly 4 is provided on the base 1. The locking member 41 can connect to the pressing plate 31 when the pressing plate 31 is in the second position. Specifically, when the pressing plate 31 is in the first position, the distance between the pressing plate 31 and the pressing area is relatively far, and the pressing... Plate 31 and the steel plate located in the pressing area are not in contact, and the steel plate is in a free state. When the pressing plate 31 is in the second position, the distance between the pressing plate 31 and the pressing area is relatively close, and the bottom surface of the pressing plate 31 presses against the top surface of the steel plate located in the pressing area. The locking member 41 passes through and is fastened to the locking hole 311 of the pressing plate 31 to fix the steel plate in multiple positions so that the steel plate is firmly fixed on the pressing area. In summary, the clamping fixture of this utility model can firmly fix the steel plate on the pressing area to ensure that the bending process of the steel plate can be carried out accurately and smoothly, thereby improving the bending accuracy of the steel plate.

[0025] The device may also include multiple locking components 4. The clamping driver 32 is connected to the middle of the top surface of the clamping plate 31. The multiple locking components 4 are respectively located on both sides of the clamping driver 32 and outside the clamping area to fasten and connect multiple positions of the clamping plate 31, thereby improving the stability of the fixed steel plate.

[0026] In addition, when the clamping plate 31 moves from the first position to the second position, the locking hole 311 and the locking member 41 are squeezed, causing the locking member 41 to undergo elastic deformation, so that the locking member 41 passes through the locking hole 311 and is fastened to the locking hole 311.

[0027] Furthermore, the top of the locking member 41 is provided with two locking parts 411 spaced apart in the horizontal direction, and the top of the side of the locking part 411 away from the other locking part 411 is provided with a pressing surface 4111; when the pressing plate 31 moves from the first position to the second position, the locking hole 311 abuts against the pressing surface 4111, causing the two locking parts 411 to elastically deform, thereby bringing the two locking parts 411 closer together so that they can pass through the pressing hole 412; when the pressing plate 31 is in the second position, the locking part 411 is located above the pressing plate 31.

[0028] Among them, the extrusion surface 4111 can be a chamfered surface or a curved surface, and the distance between two extrusion surfaces 4111 gradually decreases from bottom to top.

[0029] Furthermore, the locking hole 311 is an elongated hole, and the locking member 41 is rotatably connected to the base 1. The locking member 41 can rotate to a third position and a fourth position. The maximum lateral distance between the two locking parts 411 is greater than the width of the locking hole 311 and less than the length of the locking hole 311. The width of the two locking parts 411 on both sides perpendicular to their arrangement direction is less than the width of the locking hole 311. When the locking member 41 is in the third position, the locking member 41 can lock the pressing plate 31. Specifically, the two locking parts 411 are arranged at intervals along the width direction of the locking hole 311. The maximum lateral distance is greater than the width of the latch hole 311, and the latching part 411 can be fastened to both sides of the latch hole 311 after passing through the latch hole 311; when the latching part 41 is in the fourth position, the latching part 41 and the pressure plate 31 are unlocked. Specifically, the two latching parts 411 are arranged at intervals along the length direction of the latch hole 311. Since the maximum lateral distance between the two latching parts 411 is less than the length of the latch hole 311, and the width of the two latching parts 411 on both sides perpendicular to their arrangement direction is less than the width of the latch hole 311, the pressure plate 31 will not contact the latching assembly 4 when it reciprocates in the first and second positions.

[0030] Furthermore, the specific steps for pressing the steel plate are as follows: First, the locking fastener 41 is set in the third position, and the pressing plate 31 is set in the first position. Then, the pressing plate 31 is moved downward from the first position to the second position, pressing the pressing plate 31 against the top surface of the steel plate, and the locking fastener 41 is fastened to the pressing plate 31. Next, the steel plate is bent. After the bending process is completed, the locking fastener 41 is rotated to the fourth position, and the pressing plate 31 is moved upward to the first position. Then, the locking fastener 41 is rotated to the third position.

[0031] Furthermore, the locking assembly 4 includes a locking driver 42, which is mounted on the base 1 and connected to the locking member 41. The locking driver 42 is used to drive the locking member 41 to rotate to the third position and the fourth position to facilitate locking operations and improve processing efficiency.

[0032] Furthermore, the top surface of the locking member 41 is provided with a pressing hole 412, which is located between the two locking parts 411. The pressing hole 412 penetrates the locking member 41 in a direction perpendicular to the arrangement direction of the two locking members 41, so that when the locking hole 311 presses the locking part 411, the locking member 41 itself also undergoes elastic deformation, making it easier for the locking parts 411 to approach each other.

[0033] Furthermore, the support frame 2 includes a top plate 21 and a plurality of guide rods 22. The plurality of guide rods 22 are spaced horizontally on the top surface of the base 1. The top plate 21 is disposed on the top surface of each guide rod 22. The pressing plate 31 has a plurality of guide holes 312 extending vertically. Each guide hole 312 corresponds to one of the guide rods 22. The guide holes 312 are slidably connected to the guide rods 22 in the vertical direction. The guide rods 22 are used to guide the pressing plate 31 and ensure that the pressing plate 31 can move smoothly and accurately in the vertical direction.

[0034] Furthermore, the guide hole 312 is an elongated hole, and the guide hole 312 has a receiving groove 313 on its hole wall relative to its width direction. A plurality of balls 33 are provided in the receiving groove 313 along the length direction of the guide hole 312. The balls 33 protrude from or are flush with the hole wall of the guide hole 312. The balls 33 are connected to the guide rod 22 to increase the smoothness of the pressing plate 31 in the up and down direction. Moreover, it is less expensive than using a linear bearing directly. Furthermore, the pressing plate 31 can also be adjusted in position along the length direction of the guide hole 312, thereby adjusting its downward pressing position. In addition, the guide hole 312 has a receiving groove 313 on one side of its hole wall relative to its width direction, or it can have a receiving groove 313 on both sides of its hole wall.

[0035] Furthermore, it also includes a clamping assembly 5, which includes a clamping driver 52 and two clamping plates 51. The two clamping plates 51 are disposed opposite each other on the top surface of the base 1. The clamping driver 52 is mounted on the base 1 and connected to the clamping plates 51. The clamping driver 52 is used to drive the clamping plates 51 to move toward the other clamping plate 51.

[0036] The clamping assembly 5 is used to push the steel plate located in the pressing area to a set position and clamp it in the horizontal direction to achieve initial positioning.

[0037] Furthermore, the base 1 also includes a base frame 11 and a support plate 12. The support plate 12 is fixedly disposed on the top surface of the base frame 11. The pressing area is disposed on the top surface of the support plate 12. The locking element 41 protrudes from the top surface of the support plate 12. The support plate 12 has a through hole 121 extending in the vertical direction. The through hole 121 is an elongated hole. The clamping assembly 5 also includes a screw 53 and two connecting blocks 54. The screw 53 is rotatably disposed on the base frame 11. The length direction of the screw 53 is parallel to the length direction of the through hole 121. The two connecting blocks 54 are spaced apart along the length direction of the screw 53. The connecting blocks 54 are threadedly connected to the screw 53. The connecting blocks 54 pass through the through hole 121 and are connected to the clamping plate 51. The clamping driver 52 is connected to the screw 53. The clamping driver 52 is used to drive the screw 53 to rotate so that the two clamping plates 51 are brought closer together, thereby clamping the steel plate in the horizontal direction.

[0038] The screw 53 has threads on both sides with opposite directions, so that when the screw 53 rotates, the two connecting blocks 54 will move in opposite directions.

[0039] Furthermore, it also includes an anti-slip pad 6, which is disposed on the bottom surface of the clamping plate 31 and located above the clamping area; wherein, the anti-slip pad 6 is used to prevent the clamping plate 31 and the steel plate from sliding when the clamping plate 31 clamps the steel plate.

[0040] Furthermore, an elongated hole is a hole that extends in any direction, and the length of such a hole is greater than its width. Furthermore, an elongated hole can be a rectangular hole or a long, narrow circular hole.

[0041] Furthermore, each actuator can be a piston cylinder or an electric motor.

[0042] Furthermore, fixed setting and fixed connection refer to the fixed relative positional relationship of two components, including but not limited to fixing by connectors, fixing by welding, fixing by adhesive, fixing by integral molding, and fixing by snap-fit ​​connection.

[0043] Furthermore, sliding connection and sliding setting refer to the connection between two connected components, where one component can slide along a fixed trajectory on the other component, including but not limited to connection by sliding a slider into a groove, or connection by inserting a slider into a hole whose size and profile match the slider.

[0046] In summary, this utility model embodiment provides a clamping fixture, the technical effects of which are as follows: In this clamping fixture, the top surface of the base 1 is provided with a clamping area.
