Description
Technical Field
[0001] This utility model belongs to the field of caliper processing technology, and in particular relates to a semi-finished product clamping and transfer device for automotive caliper processing. Background Technology
[0002] In the manufacturing process of automotive calipers, the semi-finished products need to be transferred to the next process after stamping. Currently, the common method is to manually use ordinary clamps for gripping and handling, which has obvious limitations. Due to the special shape and smooth surface of the caliper semi-finished products, traditional external clamps are difficult to provide stable clamping force and are prone to slippage during transportation, causing product damage. At the same time, manual operation makes it difficult to accurately control the clamping position and force, which not only poses safety hazards but also affects the handling efficiency. In addition, the positioning height of calipers on different stamping tables is different, and there is a lack of a dedicated transfer device that can flexibly adjust the clamping position and height, resulting in poor process connection and restricting the overall efficiency of the production line.
[0003] To address these issues, we provide a semi-finished product clamping and transfer device for automotive caliper processing. Utility Model Content
[0004] The purpose of this invention is to provide a semi-finished product clamping and transfer device for automotive caliper processing. A clamping drive screw is rotatably mounted between rotating plates at both ends of a horizontal slide bar. The outer wall of the clamping drive screw has two sections of equal length with opposite helical directions. A clamping plate is screwed onto the outer side of each of the two sections of the clamping drive screw. The upper end of the clamping plate is slidably mounted on the horizontal slide bar. A connecting rod at one end of the horizontal slide bar is positioned above a movable base platform. After the caliper completes its initial stamping from the aluminum sheet, the movable base platform is pushed, and the position and height of the horizontal slide bar are adjusted so that the two clamping plates extend into the concave surface of the caliper on the stamping platform. The clamping drive screw is rotated, causing the two clamping plates to move away from each other, thus achieving internal clamping of the caliper. The height of the horizontal slide bar is then adjusted, and the movable base platform is pushed to clamp and transfer the semi-finished caliper within the stamping platform, avoiding the problem of easy dropping when using ordinary pliers.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a semi-finished product clamping and transfer device for automotive caliper processing, comprising a horizontal slide bar, a clamping drive screw, two plate clamps, and a movable base platform. Rotating plates are fixed at both ends of the horizontal slide bar. The two ends of the clamping drive screw are rotatably sleeved within the surfaces of the rotating plates on both sides. A connecting rod is fixed at the end of one rotating plate away from the horizontal slide bar. A vertical plate is fixed in the middle section of the connecting rod. An operating handle is provided on the end face of the connecting rod away from the rotating plate. The upper ends of the two plate clamps are slidably sleeved on the outside of the horizontal slide bar. A threaded channel is opened in the middle section of the plate clamps. Two sections of threads of equal length and opposite helical directions are opened on the outer wall of the clamping drive screw. The threaded channels on the two plate clamps are respectively threadedly engaged and sleeved on the outer sides of the two sections of threads on the clamping drive screw. A rubber pad is fixedly provided at the lower end of the side of the two plate clamps that are far apart from each other.

The lifting screw is threadedly engaged and sleeved inside the lifting threaded tube.
[0008] A further feature of this invention is that an outer support is fixedly provided on the outer wall of the lifting threaded tube, and a set of ball bearing seats are fixedly arranged in a circumferential array on the lower end face of the outer support. A hemispherical groove is opened on the lower end face of the ball bearing seat, and a ball is fixedly embedded in the hemispherical groove on the lower end face of the ball bearing seat.

[0010] A further feature of this invention is that a set of universal wheels is arranged in a circumferential array on the lower end face of the movable base platform.
[0011] This utility model has the following beneficial effects: This invention features a clamping drive screw with two reverse threads and two plate clamps slidably connected to a horizontal slide bar. When the drive screw rotates, the two plate clamps can move synchronously in opposite directions, achieving precise internal support clamping of the concave surface of the caliper semi-finished product. This effectively solves the problem of easy slippage in traditional external clamping methods and ensures clamping stability during transportation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1
[0021] Please see Figures 1 to 5 This utility model relates to a semi-finished product clamping and transfer device for automotive caliper processing, comprising a horizontal slide bar 1, a clamping drive screw 2, two plate clamps 3, and a movable base platform 4; rotating plates 101 are fixed at both ends of the horizontal slide bar 1, and the two ends of the clamping drive screw 2 are rotatably sleeved within the surfaces of the rotating plates 101 on both sides. A connecting rod 102 is fixed at one end of the rotating plate 101 away from the horizontal slide bar 1, and a vertical plate 102a is fixed in the middle section of the connecting rod 102. An operating handle 102b is provided on the end face of the connecting rod 102 away from the rotating plate 101. The upper ends of the two plate clamps 3 are slidably sleeved on the outside of the horizontal slide bar 1, and a threaded channel is opened in the middle section of the plate clamps 3 for clamping drive screws. The outer wall of rod 2 has two sections of threads of equal length and opposite spiral direction. The threaded channels on the two clamping plates 3 are respectively threaded and sleeved on the outer sides of the two sections of threads of the clamping drive screw 2. A rubber pad 301 is fixedly installed on the lower end of the side of the two clamping plates 3 that are far apart from each other. The movable base platform 4 is set on the lower end face of the vertical plate 102a. By setting the clamping drive screw 2 with two sections of reverse threads and the two clamping plates 3 that are slidably sleeved on the horizontal slide bar 1, when the drive screw rotates, the two clamping plates 3 can move synchronously towards or in opposite directions, realizing precise internal support clamping of the concave surface of the caliper semi-finished product. This effectively solves the problem of easy slippage in the traditional external clamping method and ensures the clamping stability during the transfer process.
[0022] Specifically, a transverse drive motor 201 is provided on the side of the vertical plate 102a near the operating handle 102b. A transmission rod 202 is fixed on the end face of the clamping drive screw 2 near the vertical plate 102a. The transmission rod 202 rotates through the rotating plate 101 and the vertical plate 102a. The end of the transmission rod 202 away from the clamping drive screw 2 is connected to the output end of the transverse drive motor 201 through a gear. The transverse drive motor 201 provides power for the rotation of the clamping drive screw 2, realizes the electric control of the opening and closing of the plate clamp 3, reduces the operating intensity, and ensures the controllability of the clamping force.
[0023] Furthermore, a rotating tray 102a-1 is rotatably mounted on the lower end face of the vertical plate 102a. A lifting screw 102a-2 is vertically fixed at the center of the lower end face of the rotating tray 102a-1. A lifting threaded tube 401 is provided below the table surface of the movable base platform 4. The upper end of the lifting threaded tube 401 rotatably passes through the table surface of the movable base platform 4. A lifting drive motor 402 is provided below the table surface of the movable base platform 4. The outer wall of the upper end of the lifting threaded tube 401 is connected to the output end of the lifting drive motor 402 through a sleeve gear. The lifting screw 102a-2 is threadedly engaged and sleeved inside the lifting threaded tube 401. This motor drive enables precise adjustment of the height of the clamping component, allowing it to adapt to the clamping position of the calipers on different stamping platforms, significantly improving the versatility and ease of operation of the device.
[0024] Furthermore, an outer support 401a is fixedly provided on the outer wall of the lifting threaded tube 401, and a set of ball bearing seats 401a-1 are fixedly arranged in a circumferential array on the lower end face of the outer support 401a. A hemispherical groove is opened on the lower end face of the ball bearing seat 401a-1, and a ball bearing 401a-2 is fixedly embedded in the hemispherical groove on the lower end face of the ball bearing seat 401a-1. An annular ball groove 403 is opened on the upper end face of the movable base platform 4, and each ball bearing 401a-2 is rolled and nested in the annular ball groove 403. Through the cooperation of the ball bearing 401a-2 and the annular ball groove 403, the axial load borne by the lifting threaded tube 401 is converted into rolling friction, which not only ensures the smooth and stable lifting process, but also significantly reduces the wear of the transmission components.
[0025] Furthermore, a set of directional slide rods 102a-3 are vertically fixed to the lower end face of the rotating tray 102a-1, and a set of slide rod sleeves 404 are provided below the table surface of the movable base platform 4. The upper end of the slide rod sleeves 404 is fixedly connected to the table surface of the movable base platform 4, and each directional slide rod 102a-3 is slidably sleeved in the respective slide rod sleeves 404. The sliding cooperation between the directional slide rods 102a-3 and the slide rod sleeves 404 provides reliable guidance for the lifting process, prevents the rotating tray 102a-1 from deflecting or shaking during the lifting process, and ensures the accuracy of clamping and positioning.
[0026] Furthermore, a set of casters 405 are arranged in a circumferential array on the lower end face of the movable base platform 4; the casters 405 enable the entire device to move in all directions.
[0027] The operation process of this embodiment is as follows: First, push the movable base platform 4 to the stamping and forming station. Adjust the angle of the horizontal slide bar 1 by operating the handle 102b to align the clamp 3 with the inner cavity of the caliper semi-finished product. Start the lifting drive motor 402 to adjust the clamping assembly to a suitable height. Start the transverse drive motor 201 to drive the clamping drive screw 2 to rotate, so that the two clamps 3 move outward synchronously on the horizontal slide bar 1 until the rubber pad 301 tightly supports the inner wall of the caliper. Operate the lifting mechanism again to lift the caliper away from the station, and then push the device to the target station. After reaching the target station, reverse the transverse drive motor 201 to retract the clamp 3, and the caliper semi-finished product can be released. The entire clamping and transfer process is stable and reliable, effectively avoiding the risk of product slippage.
