Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a clamping bracket for sheet metal processing that is easy to install. Background Technology

[0002] Sheet metal processing is a widely used technology in modern manufacturing. Through stamping, bending, welding, cutting, forming and other means, sheet metal is processed into parts and structural components of various complex shapes. During sheet metal processing, clamps are needed to hold and position the sheet metal. Existing clamps are inconvenient to use, which affects work efficiency. In addition, the clamps are not stable when holding sheet metal parts, which can easily lead to displacement of the sheet metal parts during processing, affecting the normal processing of the sheet metal parts.

[0003] For example, in the prior art, patent CN210547549U discloses a clamping bracket for sheet metal processing. This clamping bracket for sheet metal processing uses a shock-absorbing device. A support rod, a buffer spring, a first movable rod, a first tension spring, a second movable rod, and a second tension spring are installed between the support base and the base to reduce vibration and prevent mechanical shaking from causing the clamping bracket to loosen the clamping part of the sheet metal. The distance between the two rubber suction cups can be adjusted according to the size of the sheet metal. The distance between the two rubber suction cups is changed by the cooperation of the drive motor, the threaded rod, the first threaded block, the second threaded block, the limit spring, and the sliding block. After adjustment, the rubber suction cups are pressed against the top of the sheet metal by the extension and retraction of the hydraulic cylinder, thus achieving the effect of easy adjustment and wide applicability.

[0004] This device uses rubber suction cups to fix sheet metal parts by adsorption. However, the rubber suction cups are soft, and vibrations of the sheet metal parts during processing can cause deformation of the rubber suction cups, affecting the stability of the processing and the quality of the sheet metal parts. Therefore, a clamping bracket for sheet metal processing that is easy to install is designed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a sheet metal processing clamp that is easy to install.

[0006] The technical problem to be solved by this utility model is to provide a clamping bracket for sheet metal processing that is easy to install, thereby solving the problem of poor stability when using clamping brackets for sheet metal processing in the prior art to fix sheet metal parts.

[0007] This utility model provides a sheet metal processing clamp bracket that is easy to install, including a base, an inverted concave bracket, a hydraulic rod, and a pressure plate. The inverted concave bracket is fixedly installed on the upper surface of the base. The hydraulic rod is fixedly installed in the center of the upper surface of the inverted concave bracket. The pressure plate is installed at the output end of the hydraulic rod. A groove is formed on the bottom surface of the pressure plate. A bidirectional screw is rotatably installed in the groove. The threads on the left and right sides of the bidirectional screw are opposite in direction, and sliders are threaded onto the opposite threads on the left and right sides of the bidirectional screw. A drive assembly for driving the bidirectional screw to rotate is installed on the right side of the upper surface of the pressure plate.

[0008] Preferably, the slider matches the groove, and the slider slides within the groove.

[0009] Preferably, the drive assembly includes a forward and reverse motor mounted on the right end of the upper surface of the pressure plate, a first bevel gear mounted on the output end of the forward and reverse motor, and a second bevel gear fixedly disposed on the right end of the outer surface of the bidirectional screw.

[0010] Preferably, the first bevel gear and the second bevel gear mesh with each other.

[0011] Preferably, the bottom horizontal height of the slider is equal to the bottom horizontal height of the pressure plate, an embedding groove is provided in the center of the bottom surface of the slider, a spring is fixedly provided at the top of the embedding groove, and a clamping block is fixedly provided at the bottom of the spring.

[0012] Preferably, the clamping block matches the embedding groove, and when the spring is in its natural extended state, the upper part of the clamping block is embedded in the embedding groove, and the bottom of the clamping block extends out of the embedding groove. When the spring is in its maximum compressed state, the clamping block is completely embedded in the embedding groove.

[0013] Preferably, the bottom surface of the clamping block is provided with a mounting groove, and a roller is rotatably mounted in the mounting groove via a pin.

[0014] Preferably, the lower part of the roller extends out of the mounting groove.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] 1. This utility model is equipped with a drive assembly. The forward and reverse motor on the drive assembly drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear and the bidirectional screw to rotate in both directions, thereby achieving the effect of driving two sliders to slide along the slide groove in opposite directions.

[0017] 2. This utility model, by incorporating an embedded groove, a spring, and a clamping block, ensures that the bottom horizontal height of the slider is equal to that of the pressure plate. During the pressure plate's pressing of a thin sheet metal part, the slider does not affect the pressure plate's holding of the sheet metal. When the pressure plate presses the sheet metal, the clamping block contacts the base, the spring is compressed, and the drive assembly drives the bidirectional screw to rotate. As the bidirectional screw moves the two sliders in opposite directions, the clamping block at the bottom of the slider clamps and fixes the left and right surfaces of the sheet metal. This makes the device suitable for clamping and fixing sheet metal parts of different thicknesses, increasing its practicality.

[0018] 3. This utility model is equipped with rollers. Since the bottom of the rollers extends out of the mounting groove, the horizontal height of the rollers is lower than the bottom horizontal height of the clamping block. When the pressure plate presses the sheet metal part, the rollers contact the upper surface of the base. When the bidirectional screw drives the slider to move in the opposite direction, the rollers roll on the base, reducing the friction between the clamping block and the base and increasing the service life.

[0027] Example

[0028] like Figures 1-5 As shown, an embodiment of this utility model provides a sheet metal processing clamp that is easy to install, including a base 1, an inverted concave bracket 2, a hydraulic rod 3, and a pressure plate 4. The inverted concave bracket 2 is fixedly installed on the upper surface of the base 1. The hydraulic rod 3 is fixedly installed in the center of the upper surface of the inverted concave bracket 2. The pressure plate 4 is installed at the output end of the hydraulic rod 3. A groove 401 is opened on the bottom surface of the pressure plate 4. A bidirectional screw 5 is rotatably installed in the groove 401. The threads on the left and right sides of the bidirectional screw 5 are opposite in direction, and sliders 6 are threadedly connected to the opposite threads on the left and right sides of the bidirectional screw 5. A drive assembly for driving the bidirectional screw 5 to rotate is installed on the right side of the upper surface of the pressure plate 4.

[0029] In this embodiment, the slider 6 is matched with the slide groove 401, and the slider 6 slides within the slide groove 401.

[0030] In this embodiment, the drive assembly includes a forward and reverse motor 7 mounted on the right end of the upper surface of the pressure plate 4. A first bevel gear 701 is mounted on the output end of the forward and reverse motor 7, and a second bevel gear 501 is fixedly disposed on the right end of the outer surface of the bidirectional screw 5.

[0031] In this embodiment, the first bevel gear 701 and the second bevel gear 501 mesh with each other, which facilitates the first bevel gear 701 to drive the second bevel gear 501 and the bidirectional screw 5 to rotate.

[0032] By setting up a drive assembly, the forward and reverse motor 7 on the drive assembly drives the first bevel gear 701 to rotate, and the first bevel gear 701 drives the second bevel gear 501 and the bidirectional screw 5 to rotate in both directions, thereby achieving the effect of driving the two sliders 6 to slide along the slide groove 401 in opposite directions.

[0033] In this embodiment, the bottom horizontal height of the slider 6 is equal to the bottom horizontal height of the pressure plate 4. An embedding groove 601 is provided in the center of the bottom surface of the slider 6. A spring 602 is fixedly provided at the top of the embedding groove 601, and a clamping block 603 is fixedly provided at the bottom of the spring 602.

[0034] In this embodiment, the clamping block 603 matches the embedding groove 601, and when the spring 602 is in a naturally extended state, the upper part of the clamping block 603 is embedded in the embedding groove 601, and the bottom of the clamping block 603 extends out of the embedding groove 601. When the spring 602 is in a maximum compressed state, the clamping block 603 is completely embedded in the embedding groove 601.

[0035] By incorporating an embedded groove 601, a spring 602, and a clamping block 603, the bottom horizontal height of the slider 6 is equal to that of the pressure plate 4. Therefore, during the pressure plate 4's pressing of a thin sheet metal part, the slider 6 does not affect the pressure plate 4's holding of the sheet metal part. When the pressure plate 4 presses the sheet metal part, the clamping block 603 contacts the base 1, the spring 602 is compressed, and the drive assembly drives the bidirectional screw 5 to rotate. When the bidirectional screw 5 drives the two sliders 6 to move in opposite directions, the clamping block 603 at the bottom of the slider 6 can clamp and fix the left and right surfaces of the sheet metal part. This makes the device suitable for clamping and fixing sheet metal parts of different thicknesses, increasing its practicality.

[0036] In this embodiment, a mounting groove 604 is provided on the bottom surface of the clamping block 603, and a roller 605 is rotatably disposed in the mounting groove 604 via a pin.

[0037] In this embodiment, the roller 605 extends out of the mounting groove 604 from below, which facilitates the roller 605 rolling on the base 1, reduces the friction between the clamping block 603 and the base 1, and ensures service life.

[0038] With the roller 605 provided, and the roller 605 extending out of the mounting groove 604, the horizontal height of the roller 605 is lower than the bottom horizontal height of the clamping block 603. When the pressure plate 4 presses the sheet metal part, the roller 605 contacts the upper surface of the base 1. When the bidirectional screw 5 drives the slider 6 to move in the opposite direction, the roller 605 rolls on the base 1, reducing the friction between the clamping block 603 and the base 1 and increasing the service life.

[0039] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
