Description

Technical Field

[0001] This utility model is a clamping mechanism for limiting the conveying of a production line, belonging to the field of production lines. Background Technology

[0002] As competition in the automotive industry intensifies, the industry is undergoing gradual changes, with increasing levels of automation. The clamping mechanism is primarily responsible for the stability and accuracy of the vehicle body frame during positioning. The clamping mechanism includes a thin cylinder mounted on a support. During the extension and retraction of the thin cylinder, the distance between the two clamps changes. When the thin cylinder is in the retracted state, the distance between the two clamps is at its shortest. However, the size of the clamping arm connecting the moving end of the thin cylinder and the clamps is fixed. Therefore, when the two clamps work together, they can only clamp workpieces of a single thickness. When clamping workpieces of other thicknesses, it is necessary to change to the corresponding clamps, resulting in a large variety of clamps and making management inconvenient. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a clamping mechanism for conveying and limiting in a production line, so as to solve the problems mentioned in the background art. This utility model realizes the adjustment of the minimum distance between the two clamps according to the thickness of the workpiece being clamped, eliminating the need to equip clamps of different thicknesses, and facilitating management.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a clamping mechanism for limiting the conveying of a production line, comprising a support, a horizontal plate mounted on the lower part of one side of the support, a lifting component mounted on the lower surface of the horizontal plate, a thin cylinder mounted on the side of the support away from the horizontal plate, the movable end of the thin cylinder passing through the support and mounted on a slide block, the slide block being slidably mounted on the upper surface of the horizontal plate, two connecting plates rotatably mounted on the end of the slide block away from the thin cylinder via a rotating shaft, clamping arms rotatably mounted on the ends of the two connecting plates away from the slide block via a rotating shaft, an end plate mounted on the end of the clamping arm away from the connecting plate, a positioning frame between the two clamping arms, a connecting plate mounted on the upper part of the side of the positioning frame facing the support, the end of the connecting plate away from the positioning frame being connected and fixed to the support, lugs rotatably connected to the clamping arms on both the upper and lower sides of the clamping arms via rotating shafts, the lugs being connected and fixed to the positioning frame, and clamping components mounted on both end plates.

[0005] Furthermore, the clamping component includes a clamp, and two clamps are provided between the two end plates. Two transverse holes are opened on the opposite surfaces of the two end plates. Studs are installed on the opposite sides of the two clamps. Two studs on one clamp pass through the two transverse holes on the corresponding end plates. Nuts are provided on both sides of the transverse holes arranged along the length of the studs, and the nuts are threaded onto the studs.

[0006] Furthermore, a threaded head is fixedly connected to one end of the stud, and the threaded head and the stud are integrally formed. The side of the stud away from the threaded head is provided with a threaded blind hole that mates with the threaded head. The threaded head on one stud is threadedly connected to the threaded blind hole on another stud.

[0007] Furthermore, two positioning holes are provided on the back side of both chucks, and one end of the stud is installed in the positioning hole.

[0008] Furthermore, a limiting rod is provided between the two clamping arms. The limiting rod is located on the side of the positioning frame away from the support, and the limiting rod is connected to the positioning frame by screws.

[0009] Furthermore, the lifting component includes a U-shaped frame, with the U-shaped frame installed on the lower surface of the horizontal plate. A detachable connecting seat is installed inside the U-shaped frame, and a lifting cylinder is provided on the lower side of the connecting seat. The movable end of the lifting cylinder is connected to the connecting seat, and a vertical plate is provided on one side of the connecting seat that slides in contact with the connecting seat. The cylinder body end of the lifting cylinder is connected and fixed to the vertical plate. A base plate is installed on the lower end of the vertical plate, and a base connected to the base plate by screws is provided on the lower side of the base plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. Control the extension and retraction of the lifting cylinder, which in turn drives the thin cylinder, support, and other components to rise or fall, thereby adjusting the height of the chuck as needed. Control the extension and retraction of the thin cylinder, and under the drive of the thin cylinder, the slide slides along the horizontal plate. At this time, the angle between the slide, connecting plate, and clamping arms changes. That is, when the thin cylinder retracts, the distance between the two clamping arms increases, which increases the distance between the two chucks. Conversely, the distance between the two chucks decreases and clamps the workpiece.

[0012] 2. Adjust the position of the stud along the transverse hole to increase or decrease the initial distance between the two chucks. Once the distance between the two chucks meets the workpiece thickness requirements, use the nut to limit the relative position of the stud and the end plate. This allows for adjustment of the minimum distance between the two chucks according to the thickness of the workpiece being clamped, eliminating the need for chucks of different thicknesses and simplifying management.

[0013] 3. Screw the threaded head of one stud into the threaded blind hole of another stud to assemble adjacent studs. Repeat this process to assemble multiple studs. This allows you to select the appropriate number of studs based on the distance between the chuck and the end plate, eliminating the need to select longer studs initially and reducing the space occupied by the studs around the outside of the chuck arm.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 and Figure 3 This utility model provides a technical solution: a clamping mechanism for limiting the conveying of a production line, including a support 7, a horizontal plate 5 installed on the lower part of one side of the support 7, a U-shaped frame 4 installed on the lower surface of the horizontal plate 5, a detachable connecting seat 3 installed inside the U-shaped frame 4, a lifting cylinder 17 provided on the lower side of the connecting seat 3, the movable end of the lifting cylinder 17 connected to the connecting seat 3, a vertical plate 2 provided on one side of the connecting seat 3 in sliding contact with the connecting seat 3, the cylinder end of the lifting cylinder 17 connected and fixed to the vertical plate 2, a base plate 18 installed on the lower end of the vertical plate 2, a base 1 connected to the base plate 18 by screws on the lower side of the base plate 18, the base 1, the base plate 18 and the vertical plate 2 together serve to support the lifting cylinder 17.

[0022] See Figure 1-Figure 3A thin cylinder 6 is installed on the side of the support 7 away from the horizontal plate 5. The movable end of the thin cylinder 6 passes through the support 7 and is fitted with a slide 9. The slide 9 is slidably mounted on the upper surface of the horizontal plate 5. Two connecting plates 10 are rotatably mounted on the end of the slide 9 away from the thin cylinder 6 via a rotating shaft. Clamping arms 15 are rotatably mounted on the ends of the two connecting plates 10 away from the slide 9 via rotating shafts. An end plate 13 is installed on the end of the clamping arm 15 away from the connecting plate 10. A positioning frame 11 is provided between the two clamping arms 15. A connecting plate 8 is installed on the upper part of the side of the positioning frame 11 facing the support 7. The end of the connecting plate 8 away from the positioning frame 11 is connected and fixed to the support 7. The upper and lower sides of the clamping arm 15 are provided with lugs 16 that are rotatably connected to the clamping arm 15 via rotating shafts. The lugs 16 are connected and fixed to the positioning frame 11. The lifting cylinder 1 controls the movement of the clamping arm 15. 7. The extension and retraction of the cylinder 17 causes the thin cylinder 6, support 7, and other components to rise or fall, thereby adjusting the height of the chuck 14 as needed and controlling the extension and retraction of the thin cylinder 6. Under the action of the thin cylinder 6, the slide 9 slides along the horizontal plate 5. At this time, the angle between the slide 9, the connecting plate 10, and the clamping arms 15 changes. That is, when the thin cylinder 6 retracts, the distance between the two clamping arms 15 increases, which in turn increases the distance between the two chucks 14. Conversely, the distance between the two chucks 14 decreases and clamps the workpiece. A limiting rod 12 is provided between the two clamping arms 15. The limiting rod 12 is located on the side of the positioning frame 11 away from the support 7. The limiting rod 12 is connected to the positioning frame 11 by screws. After the two chucks 14 are clamped on the workpiece, the two ends of the limiting rod 12 contact the two clamping arms 15 respectively.

[0023] See Figure 1-Figure 3 Two chucks 14 are provided between the two end plates 13. Two transverse holes 23 are opened on the opposite sides of the two end plates 13. Studs 20 are installed on the opposite sides of the two chucks 14. Two positioning holes 19 are opened on the opposite sides of the two chucks 14, so that one end of the stud 20 is installed in the positioning hole 19, which improves the stability of the connection between the stud 20 and the chuck 14. The two studs 20 on one chuck 14 pass through the two transverse holes 23 on the corresponding end plates 13. Nuts 21 are provided on both sides of the transverse holes 23 along the length of the stud 20. The nuts 21 are threaded onto the studs 20. The position of the studs 20 is adjusted along the transverse holes 23, thereby increasing or decreasing the initial distance between the two chucks 14. When the distance between the two chucks 14 meets the thickness requirements of the workpiece, the nuts 21 are used to limit the relative position of the studs 20 and the end plates 13, so as to adjust the minimum distance between the two chucks 14 according to the thickness of the clamped workpiece. There is no need to equip chucks 14 of different thicknesses, which facilitates management.

[0024] See Figure 1-Figure 4One end of the stud 20 is connected and fixed with a threaded head 22. The threaded head 22 and the stud 20 are integrally formed. The side of the stud 20 away from the threaded head 22 has a threaded blind hole 24 that mates with the threaded head 22. The threaded head 22 on one stud 20 is threaded into the threaded blind hole 24 on another stud 20, so that the threaded head 22 on one stud 20 is screwed into the threaded blind hole 24 on another stud 20, thereby realizing the assembly between two adjacent studs 20. In this way, multiple studs 20 are assembled. This allows for the selection of an appropriate number of studs 20 according to the distance between the chuck 14 and the end plate 13, without the need to select a longer stud 20 in the initial case, thus reducing the space occupied by the studs 20 around the outside of the clamp arm 15.
