Description

Technical Field

[0001] The utility model relates to the technical field of assembly, in particular to a non-return pushing mechanism for assembly. Background Art

[0002] During the process of parts assembly, especially under conditions of precision assembly, or conditions where the inner parts are heavy and inconvenient to move, such as the assembly of the inner and outer casings and movements of cylindrical compressors, and the assembly of the inner and outer casings and movements of cylindrical motors, the inner parts need to be fed step by step to complete the operation.

[0003] At present, a positioning frame and a push cylinder that are slidably installed on a support beam are often used to complete the installation. Positioning holes are provided on both the support beam and the positioning frame. Each time the push cylinder pushes the inner part, it is necessary to push the positioning frame forward and insert the positioning pins into the aligned positioning holes. After re-fixing the positioning frame, the above operations are repeated to gradually install the inner parts. The manual operation has a large workload and is cumbersome. Therefore, in order to solve the above problems, an assembly non-return pushing mechanism is proposed. Utility Model Content

[0004] The utility model aims to provide a non-return pushing mechanism for assembly, so as to reduce the workload of manual operation, thereby solving the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] Technical solution 1 provides a non-return pushing mechanism for assembly, including a push cylinder, the right end of which is connected to a non-return assembly; the non-return assembly includes a positioning frame, a first linkage rod and a second linkage rod, the right end of the push cylinder is rotatably mounted with one end of the first linkage rod, the other end of the first linkage rod is fixedly mounted with a pressure plate, the inner upper surface of the positioning frame is fixedly mounted with a rotating seat, the rotating seat is rotatably mounted with one end of the second linkage rod, and the other end of the second linkage rod is rotatably assembled with the side wall of the first linkage rod; a guide group is fixedly mounted on the lower side of the positioning frame, the pressure plate is slidably mounted inside the guide group, a gap is left between the inner lower surface of the positioning frame and the guide group and the pressure plate, and a through groove connecting the gap is provided at the bottom of the positioning frame.

[0007] Specifically, the guide group includes a first baffle plate and a second baffle plate fixedly mounted on the lower side of the positioning frame, the first baffle plate is located on the left side of the second baffle plate, and the pressure plate is slidably mounted between the first baffle plate and the second baffle plate.

[0008] Specifically, the height of the first baffle is 25 mm to 30 mm.

[0009] Specifically, a reinforcing plate is fixedly installed on the right side of the positioning frame, and a gap is also left between the inner lower surface of the positioning frame and the reinforcing plate.

[0010] Optionally, the height of the gap is 20 mm to 25 mm.

[0011] Optionally, the height of the gap is 175 mm to 185 mm.

[0012] Specifically, the number of the first linkage rods and the number of the second linkage rods are both two, and the two first linkage rods and the two second linkage rods are symmetrically arranged on both sides of the rotating seat.

[0013] Technical solution 2 provides another assembly non-return push mechanism, including all the technical features of technical solution 1, and further adding the following technical features:

[0014] Specifically, the left end of the push cylinder is also connected and installed with a non-return assembly, and the left end of the push cylinder is rotatably assembled with the upper end of the first linkage rod, and the inclination directions of the first linkage rods in the two non-return assemblies are the same.

[0015] Furthermore, a stop plate is fixedly mounted on the left surface of the positioning frame on the left side.

[0016] The beneficial effects of the utility model are as follows: through a set of check components arranged at the right end of the push cylinder, when the push cylinder pushes the part to the left once, the positioning frame can be repositioned only by manually pushing it once, thus avoiding the action of inserting the positioning pin in the prior art, thereby reducing the workload;

[0017] In addition, through the two sets of check assemblies set at the left and right ends of the push cylinder, when the push cylinder is extended, the right positioning frame does not move and the left positioning frame pushes the parts to the left. When the push cylinder is shortened, the left positioning frame does not move and the right positioning frame slides to the left. There is no need for manual pushing, which can further reduce the workload and make the assembly work more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1 and Figure 2 The utility model provides a non-return pushing mechanism for assembly, including a push cylinder 1. The push cylinder 1 can be a hydraulic cylinder, a pneumatic cylinder or an electric cylinder according to the construction conditions without affecting the implementation of the present application. The right end of the push cylinder 1 is connected and installed with a non-return component. The non-return component has a non-return function. It can translate when force is applied in one direction and can brake when force is applied in the opposite direction, thereby completing the action of gradual feeding and facilitating assembly.

[0027] Specifically, the check assembly includes a positioning frame 3, a first linkage rod 10 and a second linkage rod 2. The positioning frame 3 is a rectangular frame. The right end of the push cylinder 1 is rotatably mounted with one end of the first linkage rod 10, and the other end of the first linkage rod 10 is fixedly mounted with a pressure plate 8. The inner upper surface of the positioning frame 3 is fixedly mounted with a rotating seat 4, and the rotating seat 4 is rotatably mounted with one end of the second linkage rod 2, and the other end of the second linkage rod 2 is rotatably assembled with the side wall of the first linkage rod 10; the first linkage rod 10 and the second linkage rod 2 form a linkage structure based on the principle of a lever. Pulling the upper end of the first linkage rod 10 to the left can lift the pressure plate 8, and pushing the upper end of the first linkage rod 10 to the right can press the pressure plate 8 downward.

[0028] A guide group is fixedly installed on the lower side of the positioning frame 3, and the pressure plate 8 is slidably installed inside the guide group. The guide group plays a guiding role and can ensure that the pressure plate 8 moves in the vertical direction. The guide group also has the function of strengthening the strength of the positioning frame 3 to prevent the positioning frame 3 from being deformed by force. A gap is left between the inner lower surface of the positioning frame 3 and the guide group and the pressure plate 8, and a through groove 7 connecting the gap is opened at the bottom of the positioning frame 3; the shape of the gap and the through groove 7 forms a T-shaped through cavity, which can pass through the support beam (I-beam or square steel).

[0029] like Figure 3As shown, when the support beam is an I-beam, the height of the gap is 20 mm to 25 mm to adapt to the commonly used I-beam size, and the top of the I-beam passes through the T-shaped cavity.

[0030] like Figure 4 As shown, the height of the gap is 175 mm to 185 mm to adapt to the commonly used square steel size, and the square steel and the bottom support seat pass through the T-shaped cavity.

[0031] Specifically, the guide group includes a first baffle plate 9 and a second baffle plate 6 fixedly mounted on the lower side of the positioning frame 3 , the first baffle plate 9 is located on the left side of the second baffle plate 6 , and the pressure plate 8 is slidably mounted between the first baffle plate 9 and the second baffle plate 6 .

[0032] Furthermore, since the first baffle plate 9 is close to the first linkage rod 10 , in order to avoid motion interference, the height of the first baffle plate 9 is 25 mm to 30 mm, ensuring that the pressure plate 8 is guided without affecting the swing of the first linkage rod 10 .

[0033] A reinforcing plate 5 is fixedly installed on the right side of the positioning frame 3, and a gap is also left between the inner lower surface of the positioning frame 3 and the reinforcing plate 5; the reinforcing plate 5 is also used to strengthen the strength of the positioning frame 3 to further prevent the positioning frame 3 from being deformed by force.

[0034] Specifically, the number of the first linkage rod 10 and the second linkage rod 2 are both two, and the two first linkage rods 10 and the two second linkage rods 2 are symmetrically arranged on both sides of the rotating seat 4; such an arrangement makes the movement of the first linkage rod 10 and the second linkage rod 2 more stable and has a stronger force-bearing capacity.

[0035] The working principle of this embodiment:

[0036] When assembling parts, the check assembly is installed on the support beam, and the left end of the push cylinder 1 is pressed against the parts. When the push cylinder 1 is gradually extended, a force to the right can be applied to the upper end of the first linkage rod 10, and the linkage action of the first linkage rod 10 and the second linkage rod 2 can push the pressure plate 8 downward, so that the lower surface of the pressure plate 8 is close to the support beam. At this time, the positioning frame 3 cannot move, and the purpose of pushing the parts to the left is achieved; when the push cylinder 1 is extended to the longest and the parts are still not installed in place, the push cylinder 1 can be shortened and reset, and the push cylinder 1 is held and pulled to the left. At this time, a force to the left is applied to the upper end of the first linkage rod 10, and the pressure plate 8 can be lifted upward through the linkage action of the first linkage rod 10 and the second linkage rod 2. At this time, the positioning frame 3 can also slide to the left along the support beam. After the positioning frame 3 is close to the parts, the above action is repeated, and the parts can be pushed again until the assembly of the parts is completed, which can reduce the workload of manual operation.

[0037] Embodiment 2

[0038] See also Figure 5The utility model provides another assembly non-return pushing mechanism, including all the technical features of the first embodiment, and further added technical features are as follows:

[0039] The left end of the push cylinder 1 is also connected and installed with a check assembly, and the left end of the push cylinder 1 is rotatably assembled with the upper end of the first linkage rod 10. The inclination directions of the first linkage rods 10 in the two check assemblies are the same, so that the two check assemblies work in the same way; in addition, a stop plate 11 is fixedly installed on the left surface of the left positioning frame 3, and the stop plate 11 is made of rubber material, which can avoid scratches on the contact parts.

[0040] The working principle of this embodiment:

[0041] When assembling parts, two non-return assemblies are installed on the support beam, and the upper support plate 11 of the left positioning frame 3 presses the parts tightly. When the push cylinder 1 gradually extends, the right positioning frame 3 remains stationary, and the left positioning frame 3 pushes the parts to the left; when the push cylinder 1 is extended to the longest and the parts are still not installed in place, the push cylinder 1 is controlled to shorten. At this time, the left positioning frame 3 remains stationary, while the right positioning frame 3 is pulled to the left. After the right positioning frame 3 approaches the parts, the above action is repeated, and the parts can be pushed again until the parts are assembled; compared with the first embodiment, no manual movement is required, making the assembly work more convenient.
