Description

Technical Field

[0001] This utility model relates to the field of mechanical production technology, and in particular to a hoisting and assembly device for mechanical production. Background Technology

[0002] Mechanical manufacturing is the process of transforming raw materials into mechanical products with specific functions through physical processing, energy conversion, and technological integration, encompassing the entire chain of activities from design to delivery. Its essence is the dual transformation of material form and functional attributes through technological means, and it is one of the core pillars of the modern industrial system. Lifting and assembly in mechanical manufacturing refers to the process of using lifting equipment to hoist mechanical parts, components, or complete machines to designated locations, and completing the assembly through precise positioning and connection processes. It is a key technology connecting the production and assembly stages in mechanical manufacturing.

[0003] In the existing technology, when the device is in use, if the lifting device can only clamp the corresponding shaft parts, when it is necessary to lift the same type of parts with different diameters, the entire set of clamps must be replaced, which increases downtime and reduces the efficiency of the device. When the size of the clamps and the workpieces do not match, the pressure distribution on the contact surface is uneven, which can easily cause the workpieces to slip during lifting. For example, if thin-walled box-shaped workpieces are clamped too tightly, they may deform due to excessive local stress; if the clamping force is insufficient, they may fall off due to vibration, which may cause safety hazards to the user. Therefore, it is necessary to improve the lifting and assembly device for mechanical production to solve the above problems. Utility Model Content

[0004] In order to overcome the problem that hoisting and assembly devices used in mechanical production cannot adapt to clamping different sizes of parts, thus reducing efficiency and causing safety hazards.

[0005] The technical solution of this utility model is as follows: a hoisting and assembly device for mechanical production, including a connecting support plate, a second cylinder and a clamping assembly. A support column for supporting the device is fixedly connected to the bottom of the connecting support plate, and an installation support plate for adjusting and supporting the device is fixedly connected to the bottom of the support column. The clamping assembly is provided with a limiting compression pad for preventing slippage of the clamped items. The second cylinder is mounted on the installation support plate, and a first pneumatic telescopic rod is provided on the second cylinder. An adjusting bracket is rotatably connected inside the first pneumatic telescopic rod, and a fixed adjusting shaft is fixedly connected to the adjusting bracket. The fixed adjusting shaft is rotatably connected inside the installation support plate, and a connecting bracket is fixedly connected to the fixed adjusting shaft. A fixed limiting plate is fixedly connected to the bottom of the connecting bracket.

[0006] Preferably, there are two connecting brackets, and the two connecting brackets are symmetrically fixedly connected to the fixed adjustment shaft.

[0007] Preferably, the mounting support plate has a groove at the corresponding position of the adjusting bracket, and the adjusting bracket rotates inside the groove.

[0008] Preferably, the mounting support plate has a first cylinder inside, and a push connecting rod is provided at the bottom of the first cylinder. A limiting extrusion plate for limiting the position of the part is fixedly connected to the bottom of the push connecting rod.

[0009] Preferably, two limiting support rods are provided between the limiting extrusion plate and the first cylinder, and the two limiting support rods are symmetrically and fixedly connected between the first cylinder and the limiting extrusion plate.

[0010] Preferably, the clamping assembly includes a third cylinder, which is mounted on the fixed limiting plate. The output end of the third cylinder is fixedly connected to a second pneumatic telescopic rod. The inner side of the second pneumatic telescopic rod is fixedly connected to a compression clamping plate. A sliding limiting rod is fixedly connected to the compression clamping plate and is slidably connected inside the fixed limiting plate. An adjusting rotating rod is rotatably connected inside the compression clamping plate. A support mounting plate is fixedly connected to the adjusting rotating rod, and a fixing bolt is threaded inside the adjusting rotating rod.

[0011] Preferably, there are two sliding limit rods, and the two sliding limit rods are symmetrically slidably connected inside the mounting support plate.

[0012] The beneficial effects of this utility model are:

[0013] 1. Compared to hoisting and assembly devices used in mechanical production that cannot accommodate clamping different sizes of parts, this device uses a second cylinder to drive a first pneumatic telescopic rod to push an adjusting bracket, which in turn drives a connecting bracket on a fixed adjusting shaft to press and fix the mechanical parts with a fixed limiting plate. This can satisfy the fixing of mechanical parts of different sizes and categories, eliminating the need for frequent changes of clamping fixtures, reducing downtime, improving the efficiency of the device, and preventing uneven pressure distribution on the contact surface when the fixture and workpiece size do not match, which could cause the workpiece to slip during hoisting. This reduces safety hazards and effectively prevents the reduced efficiency and safety risks caused by the inability of hoisting and assembly devices used in mechanical production to accommodate different sizes of parts.

[0014] 2. The second pneumatic telescopic rod is driven by the third cylinder and, under the limit of the sliding limit rod, it drives the squeezing and clamping plate to clamp and fix the mechanical parts. This can meet the fixing needs of mechanical parts of different sizes and categories, without the need to frequently change the clamping fixtures, thus improving the efficiency of the device and ensuring the stability of the device in clamping mechanical parts, meeting the needs of users for hoisting and assembly.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a hoisting and assembly device for mechanical production, including a connecting support plate 1, a second cylinder 804, and a clamping assembly. A support column 2 for supporting the device is fixedly connected to the bottom of the connecting support plate 1, and an adjusting support plate 3 for adjusting the device is fixedly connected to the bottom of the support column 2. The clamping assembly is provided with a limiting compression pad 4 to prevent slippage of the clamped item. The second cylinder 804 is mounted on the adjusting support plate 3, and a first pneumatic telescopic rod 805 is mounted on the second cylinder 804. An adjusting bracket 806 is rotatably connected inside the first pneumatic telescopic rod 805. A fixed adjusting shaft 807 is fixedly connected, and the fixed adjusting shaft 807 is rotatably connected inside the mounting support plate 3. A connecting bracket 808 is fixedly connected to the fixed adjusting shaft 807, and a fixed limiting plate 809 is fixedly connected to the bottom of the connecting bracket 808. The first pneumatic telescopic rod 805 is driven by the second cylinder 804 to push the adjusting bracket 806 to slide inside the mounting support plate 3. The adjusting bracket 806 pulls the fixed adjusting shaft 807 to rotate inside the mounting support plate 3. The fixed adjusting shaft 807 drives the fixed limiting plate 809 on the connecting bracket 808 to clamp the mechanical parts.

[0023] Please see Figure 2 - Figure 3 In this embodiment, two connecting brackets 808 are provided, and the two connecting brackets 808 are symmetrically fixedly connected to the fixed adjusting shaft 807. The two connecting brackets 808 make the fixed limiting plate 809 more stable when clamped. The mounting support plate 3 has a sliding groove at the corresponding position of the adjusting bracket 806. The adjusting bracket 806 rotates inside the sliding groove. By the sliding groove opened inside the mounting support plate 3 at the position corresponding to the adjusting rotating rod 906, the adjusting rotating rod 906 is limited when rotating inside the sliding groove. The mounting support plate 3 is provided with a first cylinder 801. A push connecting rod 802 is provided at the bottom of the cylinder 801. A limiting extrusion plate 803 for limiting the position of the part is fixedly connected to the bottom of the push connecting rod 802. The limiting extrusion plate 803 on the push connecting rod 802 is driven by the first cylinder 801 to extrude and fix the mechanical part. Two limiting support rods are provided between the limiting extrusion plate 803 and the first cylinder 801. The two limiting support rods are symmetrically fixed between the first cylinder 801 and the limiting extrusion plate 803. The two limiting support rods make the limiting extrusion plate 803 more stable when fixing the mechanical part.

[0024] Please see Figure 4 - Figure 5 In this embodiment, the clamping assembly includes a third cylinder 901, which is mounted on a fixed limiting plate 809. A second pneumatic telescopic rod 902 is fixedly connected to the output end of the third cylinder 901. A compression clamping plate 903 is fixedly connected to the inner side of the second pneumatic telescopic rod 902. A sliding limiting rod 904 is fixedly connected to the compression clamping plate 903, and the sliding limiting rod 904 is slidably connected inside the fixed limiting plate 809. An adjusting rotating rod 906 is rotatably connected inside the compression clamping plate 903. A support mounting plate 907 is fixedly connected to the 6. The internal thread of the adjusting rotating rod 906 is connected to a fixing bolt 908. The extrusion clamping plate 903 on the second pneumatic telescopic rod 902 is driven by the third cylinder 901 to clamp and fix the mechanical parts under the limit of the sliding limit rod 904. There are two sliding limit rods 904, and the two sliding limit rods 904 are symmetrically slidably connected inside the mounting support plate 3. The extrusion clamping plate 903 is limited and guided by the two sliding limit rods 904 when sliding.

[0025] During operation, when fixing the mechanical parts, the second cylinder 804 drives the first pneumatic telescopic rod 805 to push the adjusting bracket 806 to slide inside the mounting support plate 3. The adjusting bracket 806 pulls the fixed adjusting shaft 807 to rotate inside the mounting support plate 3. The fixed adjusting shaft 807 drives the fixed limiting plate 809 on the connecting bracket 808 to clamp the mechanical parts. The first cylinder 801 drives the limiting pressing plate 803 on the connecting rod 802 to press and fix the mechanical parts. When clamping and limiting the mechanical parts, the third cylinder 901 drives the pressing clamping plate 903 on the second pneumatic telescopic rod 902 to clamp and fix the mechanical parts under the limitation of the sliding limiting rod 904. By rotating the support mounting plate 907, the support mounting plate 907 contacts the bottom of the mechanical parts. By twisting the fixing bolt 908, the support mounting plate 907 completes the support of the mechanical parts for the mechanical parts.

[0026] Through the above steps, the second cylinder 804 drives the first pneumatic telescopic rod 805 to push the adjusting bracket 806, which in turn drives the connecting bracket 808 on the fixed adjusting shaft 807 to fix the mechanical parts with the fixed limiting plate 809. This solves the problem that the hoisting and assembly device used in mechanical production cannot adapt to clamping different sizes of parts, which reduces the efficiency of use and brings safety hazards.
