A column is welded to the upper surface of the fixed platform, and a clamping structure is provided on the column. An adjustment mechanism is provided on the upper surface of the base. The clamping structure includes an electric push rod fixed to the outside of the column. A mounting base is fixedly connected to the output end of the electric push rod. A telescopic cylinder is fixedly mounted on the side of the mounting base near the positioning rod. A clamp is fixedly connected to the output end of the telescopic cylinder. The adjustment mechanism consists of a servo motor, a gear, and a ring rack. The servo motor is fixed to the upper surface of the base, and the ring rack is welded to the outer wall of the fixed platform. The gear meshes with the ring rack. This engine cylinder block machining fixture, through the combined use of the electric push rod and the adjustment mechanism, can effectively improve the practicality of the clamping mechanism, achieving the advantages of high practicality and the ability to adjust the clamping structure.

[0004] However, the aforementioned engine cylinder block machining fixture mainly considers the existing machining fixtures and the problem that it is not convenient to adjust the clamping structure. However, this machining fixture is not convenient for stably clamping cylinder blocks that are placed vertically or horizontally.

[0005] In view of this, it is necessary to develop an engine cylinder block machining fixture that can stably clamp cylinder blocks that are placed vertically or horizontally. Utility Model Content

[0006] The purpose of this utility model is to provide an engine cylinder block machining fixture to solve the technical problem mentioned in the background art that the machining fixture is not convenient for stably clamping cylinder blocks that are placed vertically or horizontally.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an engine cylinder block machining fixture, comprising: a mounting base, on which mounting plates are symmetrically mounted, a second pneumatic cylinder is mounted on one side of the mounting plate, and the output end of the second pneumatic cylinder penetrates the inner side of the mounting plate, a rotation adjustment assembly is mounted on the output end of the second pneumatic cylinder, the rotation adjustment assembly includes a mounting shaft, a rotating sleeve, and a clamping plate, the mounting shaft is mounted on the telescopic end of the second pneumatic cylinder, the rotating sleeve is rotatably mounted on the outside of the mounting shaft, and the clamping plate is mounted on one end of the rotating sleeve.

[0008] Preferably, a fixing hole is provided at one end of the mounting shaft, a fixing screw is installed through the inner side of the clamping plate, and the fixing screw is threadedly connected to the fixing hole. Anti-slip pads are symmetrically installed on one side of the clamping plate.

[0009] Preferably, the mounting plate has a groove on its inner side.

[0010] Preferably, a mounting cylinder is installed on the top of the mounting base, a first pneumatic cylinder is installed inside the mounting cylinder, and a support plate is installed on the telescopic end of the first pneumatic cylinder.

[0011] Preferably, sliders are symmetrically installed on both sides of the support plate, and the sliders are connected to the slide grooves. Through holes are provided at the top of the four corners of the support plate.

[0012] Preferably, the top of the mounting base is symmetrically equipped with support screws, and the support screws pass through the top of the support plate through through holes. The outer threads of the support screws are fitted with limit sleeves, and the limit sleeves are located below the support plate. The bottom of the mounting base is equipped with a fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the clamping plate is installed through a rotating adjustment assembly. The rotating sleeve in the rotating adjustment assembly can rotate on the outside of the mounting shaft, thereby allowing the clamping plate to rotate. This facilitates the clamping of the engine cylinder block, whether it is placed vertically or horizontally, ensuring stable clamping of the engine cylinder block. The first pneumatic cylinder is used to convert pneumatic energy into kinetic energy, thereby driving the support plate at the output end to move up and down. The support plate is used to support the engine cylinder block, allowing the clamping height of the engine cylinder block to be adjusted.

[0015] 2. In this utility model, the limiting sleeve can be adjusted in height by rotating on the outside of the supporting screw. After the height of the supporting plate is adjusted, the limiting sleeve is rotated to the bottom of the supporting plate to support the supporting plate and make the supporting plate more stable. Since the engine cylinder block is heavy, it avoids the bottom being supported only by the first air pressure cylinder, which would result in low stability of the supporting plate.

[0024] Please see Figure 1 and Figure 2 A machining fixture for engine cylinder blocks;

[0025] The device includes: a mounting base 1 and a rotation adjustment assembly. A mounting plate 10 is symmetrically mounted on the top of the mounting base 1. A second pneumatic cylinder 11 is mounted on one side of the mounting plate 10, and the output end of the second pneumatic cylinder 11 passes through the inner side of the mounting plate 10. A rotation adjustment assembly is mounted on the output end of the second pneumatic cylinder 11. The rotation adjustment assembly includes a mounting shaft 12, a rotating sleeve 14, and a clamping plate 18. The mounting shaft 12 is mounted on the telescopic end of the second pneumatic cylinder 11. The rotating sleeve 14 is rotatably mounted on the outer side of the mounting shaft 12. The clamping plate 18 is mounted on one end of the rotating sleeve 14. A fixing hole 13 is opened at one end of the mounting shaft 12. A fixing screw 15 is installed through the inner side of the clamping plate 18, and the fixing screw 15 is threadedly connected to the fixing hole 13. Anti-slip pads 16 are symmetrically mounted on one side of the clamping plate 18.

[0026] Mounting base 1 provides a position for mounting plate 10. Mounting plate 10 is used to mount second pneumatic cylinder 11. Second pneumatic cylinder 11 is used to convert pneumatic energy into kinetic energy, thereby driving clamping plate 18 to move towards each other through the rotation adjustment assembly installed at the output end to clamp the engine cylinder block. Since clamping plate 18 is mounted through rotation adjustment assembly, the rotating sleeve 14 in rotation adjustment assembly can rotate outside the mounting shaft 12, so clamping plate 18 can rotate, which facilitates clamping of vertically or horizontally placed engine cylinder blocks, so that the engine cylinder block can be stably clamped whether it is vertically or horizontally placed. After adjustment, clamping plate 18 is rotated and fixed by fixing screw 15, and anti-slip pad 16 makes clamping plate 18 clamping engine cylinder block more stably.

[0027] Please see Figure 1 , Figure 3 and Figure 4 A machining fixture for engine cylinder blocks;

[0028] The mounting plate 10 includes a support plate 7 and a support screw 3. A groove 17 is provided on the inner side of the mounting plate 10. A mounting cylinder 5 is installed on the top of the mounting base 1. A first pneumatic cylinder 6 is installed inside the mounting cylinder 5. The extension end of the first pneumatic cylinder 6 is equipped with the support plate 7. Slider blocks 8 are symmetrically installed on both sides of the support plate 7 and are connected to the groove 17. Through holes 9 are provided at the top of the four corners of the support plate 7. Support screws 3 are symmetrically installed on the top of the mounting base 1 and pass through the top of the support plate 7 through the through holes 9. A limit sleeve 4 is threaded on the outer side of the support screw 3 and is located below the support plate 7. A fixing plate 2 is installed at the bottom of the mounting base 1.

[0029] The mounting cylinder 5 provides a position for the installation of the first pneumatic cylinder 6, which converts pneumatic energy into kinetic energy to drive the support plate 7 at the output end to move up and down. The support plate 7 supports the engine cylinder block, allowing the clamping height of the engine cylinder block to be adjusted. The through hole 9 provides space for the support screw 3 to pass through. When the support plate 7 moves, the slider 8 slides inside the slide groove 17, making the movement of the support plate 7 more stable. The support screw 3 provides a position for the installation of the limiting sleeve 4. The limiting sleeve 4 can be adjusted in height by rotating on the outside of the support screw 3. After the height of the support plate 7 is adjusted, the limiting sleeve 4 is rotated to the bottom of the support plate 7 to support the support plate 7, making the support plate 7 more stable. Since the engine cylinder block is heavy, the stability of the support plate 7 is not low if the bottom is only supported by the first pneumatic cylinder 6. The fixing plate 2 is used to install and use the fixture.

[0030] The working principle is as follows: First, the fixture is fixed in place by the fixing plate 2. The engine cylinder block to be processed is placed on the top of the support plate 7 for support. The first pneumatic cylinder 6 drives the support plate 7 to move up and down, so that the engine cylinder block is moved to the clamping position. Then, the second pneumatic cylinder 11 drives the clamping plate 18 installed at the output end to move and clamp the engine cylinder block. This fixture can stably clamp engine cylinder blocks that are placed vertically or horizontally.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
