Description

Technical Field

[0001] This utility model relates to the field of cylinder block processing, and in particular to a rotary clamping fixture for automotive cylinder blocks. Background Technology

[0002] The automotive cylinder block rotary clamping fixture is a tooling used to fix and rotate automotive cylinder blocks. It uses a specific mechanism to position and clamp the cylinder block to facilitate machining or inspection, thereby improving machining efficiency and stability.

[0003] Existing automotive cylinder block rotary clamping fixtures typically have their positioning structures installed in a customized manner based on the specific cylinder block and cylinder liner positions to be processed. The spacing of these positioning structures cannot be adjusted, resulting in limited applicability, increased production costs, and a relatively simple application range.

[0004] Therefore, the existing rotary clamping fixtures for automotive cylinder blocks typically require custom installation of their positioning structures based on the specific cylinder block and cylinder liner positions to be processed. This lack of adjustment of the spacing between the positioning structures results in limited applicability, increased production costs, and a simplistic approach to their use. To address this, a rotary clamping fixture for automotive cylinder blocks can be designed. By incorporating a drive motor, the output of the motor rotates a bidirectional lead screw. This screw, in turn, moves two threaded moving seats in opposite directions, thereby moving the connected positioning components. This allows for adjustment of the spacing between the two positioning components, adapting to different cylinder blocks. Utility Model Content

[0005] To overcome the problem that existing automotive cylinder block rotary clamping fixtures typically require custom installation of their positioning structures based on the specific cylinder block and cylinder liner positions to be machined, making it impossible to adjust the spacing of the positioning structures, resulting in limited applicability, increased production costs, and a single application method.

[0006] The technical solution of this utility model is as follows: a rotary clamping fixture for automobile cylinder blocks, including a base plate; it also includes a drive motor, a mounting groove, a double-acting lead screw, a movable seat, and a positioning component. The drive motor is installed at the center of the right side surface of the base plate, and a mounting groove is opened at the middle of the upper surface of the base plate. The double-acting lead screw is rotatably connected to the left and right sides of the inner surface of the mounting groove. The output end of the drive motor passes through the right side wall of the base plate and is connected to the right end of the double-acting lead screw. Two symmetrical movable seats are threadedly connected to the outer surface of the double-acting lead screw, and a positioning component is provided on the upper surface of the movable seats.

[0007] Preferably, by setting a drive motor, its output end will drive the bidirectional lead screw to rotate during operation. When the bidirectional lead screw rotates, it will drive the two moving seats that are threaded with it to move synchronously in opposite directions, thereby driving the positioning components connected to it to move, thus realizing the adjustment of the distance between the two positioning components. This can be used to adapt to different cylinder blocks, thereby solving the problem that the position of the positioning structure of the existing automotive cylinder block rotary clamping tool is usually customized according to the position of the cylinder liner to be processed, and the distance of its positioning structure cannot be adjusted, resulting in a relatively simple use, a low range of adaptability, and increased production costs.

[0008] Preferably, the positioning assembly includes a first cylinder, a mounting base, a positioning seat, a first pressure rod, and a connecting seat; the first cylinder is mounted on the upper surface of the movable base, the mounting base is provided on the upper surface of the first cylinder, the telescopic end of the first cylinder is slidably connected to the mounting base, three circumferentially distributed positioning seats are provided on the side of the upper surface of the mounting base, the first pressure rod is rotatably connected to the inner side of the positioning seat, the connecting seat is provided on the telescopic end of the first cylinder, and the end of the first pressure rod away from the positioning seat is rotatably connected to the connecting seat.

[0009] Preferably, the upper surface of the base plate is provided with multiple supports, and the top of the supports is equipped with pads.

[0010] Preferably, lifting seats are provided at the corners of the upper surface of the base plate, and lifting rings are installed at the ends of the lifting seats.

[0011] Preferably, a second cylinder is provided on both the front and rear sides of the upper surface of the base plate. Two second pressure rods are rotatably connected to the outer surface of the telescopic end of the second cylinder. A protective block is installed at the end of the second pressure rod away from the second cylinder, and a fixing bolt is installed on the top surface of the second cylinder.

[0012] Preferably, a gear is installed at the center of the bottom surface of the base plate, and a mating groove is formed on the bottom surface of the gear.

[0013] Preferably, both the pad and the protective block are made of rubber.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a drive motor, its output end will drive the bidirectional lead screw to rotate during operation. When the bidirectional lead screw rotates, it will drive the two moving seats that are threaded with it to move synchronously in opposite directions, thereby driving the positioning components connected to it to move. This realizes the adjustment of the distance between the two positioning components, so as to adapt to different cylinder blocks. This solves the problem that the position of the positioning structure of the existing automotive cylinder block rotary clamping tool is usually customized according to the position of the cylinder liner to be processed, and the distance of the positioning structure cannot be adjusted, resulting in a relatively simple use, a low range of adaptability, and increased production costs.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment of a rotary clamping fixture for automotive cylinder blocks, including a base plate 1; it also includes a drive motor 2, a mounting groove 3, a bidirectional lead screw 4, a movable seat 5, and a positioning assembly. The drive motor 2 is mounted at the center of the right side surface of the base plate 1. The mounting groove 3 is formed in the middle of the upper surface of the base plate 1. The bidirectional lead screw 4 is rotatably connected to the left and right sides of the inner surface of the mounting groove 3. The output end of the drive motor 2 passes through the right side wall of the base plate 1 and is connected to the right end of the bidirectional lead screw 4. Two symmetrical movable seats 5 are threadedly connected to the outer surface of the bidirectional lead screw 4. The upper surface of the movable seat 5 is provided with a positioning assembly. By setting the drive motor 2, the fixture can be used to rotate the cylinder block. During operation, the output of motor 2 drives the bidirectional lead screw 4 to rotate. When the bidirectional lead screw 4 rotates, it drives the two moving seats 5 that are threaded together to move synchronously in opposite directions, thereby moving the positioning components connected to it. This allows for adjustment of the distance between the two positioning components, thus adapting to different cylinder blocks. This solves the problem that existing automotive cylinder block rotary clamping fixtures typically have their positioning structures customized according to the specific cylinder block and cylinder liner positions to be processed, making it impossible to adjust the distance of their positioning structures. This results in limited applicability, increased production costs, and a relatively limited range of applications.

[0025] Please see Figures 1-5 In this embodiment, the positioning assembly includes a first cylinder 61, a mounting base 62, a positioning seat 63, a first pressure rod 64, and a connecting seat 65. The first cylinder 61 is mounted on the upper surface of the movable seat 5, and the mounting base 62 is provided on the upper surface of the first cylinder 61. The telescopic end of the first cylinder 61 is slidably connected to the mounting base 62. Three circumferentially distributed positioning seats 63 are provided on the side of the upper surface of the mounting base 62. The first pressure rod 64 is rotatably connected to the inner side of the positioning seat 63. The telescopic end of the first cylinder 61 is provided with the connecting seat 65. The end of the first pressure rod 64 away from the positioning seat 63 is rotatably connected to the connecting seat 65. By setting the first cylinder 61, when the cylinder body is placed on the upper surface of the tooling... After that, the first cylinder 61 can be activated, causing its telescopic end to move outward, thereby driving the connecting seat 65 to move and cooperate with the positioning seat 63, driving the end of the first pressure rod 64 to press down, thereby pressing the cylinder body for positioning. The upper surface of the base plate 1 is provided with multiple supports 7, and the top of the supports 7 is equipped with pads 8. By setting the supports 7 and pads 8, the bottom points of the cylinder body can be supported, ensuring the balance during positioning. The upper surface of the base plate 1 is provided with lifting seats 9 at the corners, and the ends of the lifting seats 9 are equipped with lifting rings 10. By setting the lifting seats 9 and lifting rings 10, it is convenient for workers to move the entire device with the help of lifting equipment, improving convenience.

[0026] Please see Figures 1-6In this embodiment, a second cylinder 11 is provided on both the front and rear sides of the upper surface of the base plate 1. Two second pressure rods 12 are rotatably connected to the outer surface of the telescopic end of the second cylinder 11. A protective block 13 is installed at the end of the second pressure rod 12 away from the second cylinder 11. A fixing bolt 14 is installed on the top surface of the second cylinder 11. By setting the second cylinder 11, the two second pressure rods 12 can be driven to adjust their position during operation, thereby adapting to the cylinder body and completing the positioning. A gear 15 is installed at the center of the bottom surface of the base plate 1. A docking groove 16 is opened on the bottom surface of the gear 15. By setting the gear 15 and the docking groove 16, it is convenient for the operator to dock the entire device with the external motor transmission structure, so that the entire device can rotate at an angle and improve the comprehensiveness of processing. The pad 8 and the protective block 13 are both made of rubber. By using rubber to make the pad 8 and the protective block 13, they can have a high buffering effect and effectively protect the outer surface of the cylinder body from wear.

[0027] During operation, the first cylinder 61 is activated after the cylinder body is placed on the upper surface of the tooling, causing its telescopic end to move outward, thereby moving the connecting seat 65 to cooperate with the positioning seat 63. This causes the end of the first pressure rod 64 to press down, thus pressing the cylinder body into position. The support 7 and pad 8 provide support for the bottom points of the cylinder body, ensuring balance during positioning. The lifting seat 9 and lifting ring 10 facilitate the movement of the entire device by the operator using lifting equipment, improving convenience. The second cylinder 11 drives the two second pressure rods 12 to adjust their positions during operation, thus adapting to the cylinder body and completing positioning. The gear 15 and docking groove 16 facilitate the docking of the entire device with the external motor transmission structure, allowing the entire device to rotate at an angle, improving the comprehensiveness of processing. The use of rubber pad 8 and protective block 13 provides a high buffering effect, effectively protecting the outer surface of the cylinder body from wear.

[0028] Through the above steps, by setting the drive motor 2, its output end will drive the bidirectional lead screw 4 to rotate during operation. When the bidirectional lead screw 4 rotates, it will drive the two moving seats 5 that are threaded with it to move synchronously in opposite directions, thereby driving the positioning components connected to it to move, thus realizing the adjustment of the distance between the two positioning components. This can be used to adapt to different cylinder blocks, thereby solving the problem that the position of the positioning structure of the existing automotive cylinder block rotary clamping tool is usually customized according to the position of the cylinder liner to be processed, and the distance of its positioning structure cannot be adjusted, resulting in a relatively simple use, a low range of adaptability, and increased production costs.
