Description

Technical Field

[0001] This invention belongs to the field of paper-plastic parts processing, and in particular relates to a clamp for transferring paper-plastic parts. Background Technology

[0002] In the processing of paper-plastic parts, it is necessary to transfer the paper-plastic parts between different processes. Existing clamps are of two types: The first type uses a cylinder to drive two clamping plates to hold the side walls of the paper-plastic part. Some finished or semi-finished paper-plastic parts have low structural strength, and the paper-plastic part will deform to a certain extent during the process of clamping the side walls, which will affect the product quality or add extra processes for straightening, increasing production costs. The second type uses suction cups to clamp the top of the paper-plastic part (the top can be understood as the bottom of the paper-plastic cup). This suction clamp may also cause the paper-plastic part to deform. Although some suction cups can clamp the top and side walls of the paper-plastic part at the same time, it often happens that only the side walls are clamped while the top is not, which makes the deformation of the paper-plastic part more serious. Moreover, this type of clamp cannot adjust its clamping position according to the structural strength of the paper-plastic part, resulting in a limited range of applications. Summary of the Invention

[0010] The diameter of the slider is matched with the inner diameter of the sleeve;

[0011] The bottom of the slider has a ventilation groove, and the inner wall of the ventilation groove has a ventilation hole. When the slider is in the first position, the ventilation hole is connected to the side suction hole. When the slider is in the second position, the ventilation hole is not connected to the side suction hole.

[0012] Furthermore, both ends of the inner side of the connecting pipe are provided with internal threads;

[0013] The lower end of the inner side of the connecting tube is provided with a lower limit ring, and a compression spring is provided between the slider and the lower limit ring;

[0014] The connecting tube is located between the slider and the lower limit ring, where it communicates with the sleeve.

[0015] Furthermore, the lower limiting ring is threadedly connected to the connecting pipe;

[0016] The upper end of the inner side of the connecting pipe is provided with an upper limit ring, which is threadedly connected to the connecting pipe;

[0021] Furthermore, the side suction hole is a through hole, and the side suction hole is opened on the outer wall of the housing and sealed with a sealing bolt.

[0022] Furthermore, an annular limiting boss is fixedly provided on the inner side of the lower end of the upper suction hole, and a sealing gasket is provided between the annular limiting boss and the sleeve.

[0030] (1) The paper-plastic part transfer fixture of the present invention can be changed to be suitable for paper-plastic parts with different structural strengths by adjusting the position of the slider, thus broadening the scope of application of the fixture.

[0031] (2) The paper-plastic part transfer clamp of the present invention, when the paper-plastic part enters the placement groove, the negative pressure device works, the sleeve is in a negative pressure state, after the upper suction hole clamps the top of the paper-plastic part, the negative pressure in the sleeve increases, which plays a preliminary positioning role for the paper-plastic part. The pressure generated by the atmospheric pressure at the end of the slider away from the compression spring is greater than the elastic force of the compression spring, the compression spring is further compressed, the slider moves downward, the vent hole and the connecting pipe are in a connected state, the side suction clamp clamps the side wall of the paper-plastic part, preventing the paper-plastic part from deforming. If the upper suction hole does not clamp the top of the paper-plastic part, the negative pressure in the sleeve will not increase, and the side suction hole will not clamp the side wall of the paper-plastic part, thereby preventing the paper-plastic part from deforming due to the side suction hole clamping the side wall of the paper-plastic part. It is suitable for paper-plastic parts with low structural strength.

[0032] (3) The paper-plastic part transfer fixture of the present invention has a buffer groove connected to the connecting pipe. The buffer groove has the effect of buffering air pressure, so that the air pressure in each connecting pipe is consistent, thereby ensuring the effect of suctioning the side wall of the paper-plastic part.

[0033] (4) The paper-plastic part transfer fixture of the present invention has a side suction hole that is a through hole. The side suction hole is opened on the outer side wall of the housing and sealed with a sealing bolt. The through hole structure is easy to process and reduces the manufacturing cost of the fixture.

[0050] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] A clamp for transferring paper-plastic parts, comprising:

[0052] The housing 1 has a placement groove 103 for placing paper-plastic parts inside. The inner side wall of the placement groove 103 has a side suction hole 101. There are multiple side suction holes 101, which are evenly arranged circumferentially along the axis of the housing 1.

[0053] In this embodiment, there are 18 side suction holes 101, arranged in rows of three, for a total of six rows, which are evenly arranged circumferentially along the axis of the housing 1.

[0054] Sleeve 3 is connected to the upper suction hole 104 at the bottom of the placement groove 103;

[0055] Slider 4 is installed inside sleeve 3. When slider 4 is in the first position, sleeve 3 is connected to side suction hole 101. When slider 4 is in the second position, sleeve 3 is not connected to side suction hole 101.

[0056] A connecting pipe 301 and a connecting pipe 302, which communicate with the inner side of the sleeve 3, are fixed on the side wall of the sleeve 3. The connecting pipe 301 is connected to the negative pressure device, and the connecting pipe 302 is connected to the side suction hole 101.

[0064] Both the upper limit ring 6 and the lower limit ring 7 have strip-shaped grooves on their end faces, which facilitate the rotation of the upper limit ring 6 and the lower limit ring 7.

[0065] The upper end of the housing 1 has a connecting hole 102 that communicates with the side suction hole 101. A pressure ring 2 is threadedly connected to the upper end of the housing 1. An annular boss 201 is fixedly provided at the lower end of the pressure ring 2. The annular boss 201 has an internal thread on its inner side and an external thread on its outer side at the upper end of the housing 1. The pressure ring 2 is threadedly connected to the housing 1 through the annular boss 201. A buffer groove 205 corresponding to the connecting hole 102 is provided at the bottom end of the pressure ring 2. The buffer groove 205 communicates with the connecting pipe 302. The buffer groove 205 has the effect of buffering air pressure, so that the air pressure in each connecting pipe is consistent, thereby ensuring the effect of suctioning the side wall of the paper-plastic part.

[0066] The upper end of the pressure ring 2 is fixed with a connecting pipe 3 204 that communicates with the buffer groove 205. The connecting pipe 3 204 is connected to the connecting pipe 2 302 through a hose 8. The hose 8 facilitates the disassembly of the sleeve 3 for use with other sizes of housing 1.

[0067] The side suction hole 101 is a through hole. The side suction hole 101 is opened on the outer side wall of the housing 1 and sealed with a sealing bolt 9. The through hole structure is easy to process and reduces the manufacturing cost of the fixture.

[0068] An annular limiting boss 105 is fixedly provided on the inner side of the lower end of the upper suction hole 104, and a sealing gasket 12 is provided between the annular limiting boss 105 and the sleeve 3. The sealing gasket 12 improves the sealing performance between the annular limiting boss 105 and the sleeve 3.

[0069] The bottom end of the pressure ring 2 has an annular sealing groove 202 and an annular sealing groove 203. The diameter of the annular sealing groove 202 is larger than the diameter of the buffer groove 205, and the diameter of the annular sealing groove 203 is smaller than the diameter of the buffer groove 205. A sealing ring 10 is provided in the annular sealing groove 202, and a sealing ring 11 is provided in the annular sealing groove 203. The sealing rings 10 and 11 improve the sealing performance between the pressure ring 2 and the housing 1.

[0070] The slider 4 has annular sealing grooves 404 and 403 on its sidewalls at both ends. A vent hole 402 is located between the annular sealing grooves 404 and 403. A sealing ring 13 is installed inside the annular sealing groove 404, and a sealing ring 14 is installed inside the annular sealing groove 403. The sealing rings 13 and 14 improve the sealing between the slider 4 and the inner sidewall of the sleeve 3.

[0071] Work process:

[0072] When this solution is implemented, sleeve 3 is connected to the robotic arm or other gripping components.

[0073] In some embodiments, the slider 4 is fixed in the first position. The operation method is to rotate the upper limit ring 6 to move the slider 4 downward. At this time, the vent hole 402 and the connecting pipe 302 are always in communication. When the paper-plastic part enters the placement groove 103, the negative pressure device works, and the sleeve 3 is in a negative pressure state. The upper suction hole 104 and the side suction hole 101, which are connected to the sleeve 3, respectively suction the top and side wall of the paper-plastic part to prevent deformation. This method is suitable for paper-plastic parts with a certain structural strength.

[0074] In some embodiments, the slider 4 is fixed in the second position. The operation method is to rotate the lower limit ring 7, which increases the elastic force of the compression spring 5. The negative pressure in the sleeve 3 cannot drive the slider 4 to move. At this time, the vent hole 402 and the connecting pipe 302 are always not in communication. When the paper-plastic part enters the placement groove 103, the negative pressure device works, and the sleeve 3 is in a negative pressure state. The upper suction hole 104, which is connected to the sleeve 3, suctions the top of the paper-plastic part. This is suitable for paper-plastic parts with high structural strength.

[0075] In some embodiments, the slider 4 moves according to the magnitude of the negative pressure within the sleeve 3. When the paper-plastic part enters the placement groove 103, the negative pressure device operates, and the sleeve 3 is under negative pressure. After the upper suction hole 104 suctions the top of the paper-plastic part, the negative pressure within the sleeve 3 increases, providing initial positioning for the paper-plastic part. The atmospheric pressure at the end of the slider 4 away from the compression spring 5 is greater than the elastic force of the compression spring 5, causing the compression spring 5 to compress further. The slider 4 moves downward, and the vent hole 402 is connected to the connecting pipe 302, thus side-suctioning the sidewall of the paper-plastic part to prevent deformation. If the upper suction hole 104 does not suction the top of the paper-plastic part, the negative pressure within the sleeve 3 will not increase, and the side suction hole 101 will not suction the sidewall of the paper-plastic part, thereby preventing deformation of the paper-plastic part caused by the side suction hole 101 suctioning the sidewall. This is suitable for paper-plastic parts with low structural strength.

[0076] By adjusting the position of slider 4, the clamp can be adapted to paper-plastic parts with different structural strengths, thus broadening the applicability of the clamp.
