Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a clamping structure for spraying plastic products. Background Technology

[0002] With the rapid development of technology, automobiles have become an essential product for families. In the field of automobile manufacturing, the bumpers, carburetor components, mudguards, spoilers, dashboards, accelerators, and clutches of automobiles are all made of plastic parts. Due to the advantages of plastics, such as being aesthetically pleasing, lightweight, and easy to process, they have become an important material for automobile body manufacturing. In modern automobile plastic parts manufacturing, it is necessary to spray waterproof and anti-corrosion materials onto the surface of the plastic parts, which requires the use of spraying jigs.

[0003] Utility model CN213078869U discloses a fixture for spraying coating the surface of automotive plastic parts, including a base. Two limiting plates are fixedly connected to the right side of the top surface of the base. One limiting plate has a clamping groove movably connected to its inner side, and the other limiting plate has a rotating shaft movably sleeved inside. One end of the rotating shaft is fixedly connected to a crank handle. This utility model fixes the different rotation directions of the plastic parts by utilizing the interaction between the teeth on the gear and the crank handle. By engaging the crank handle with different teeth, the rotation direction of the gear is adjusted, thereby adjusting the rotation direction of the clamping mechanism. This avoids the problem of a fixed fixed direction of the device, which is inconvenient for rotation. When spraying multiple surfaces of plastic parts, workers need to constantly change the clamping direction, affecting the spraying progress, resulting in low spraying efficiency and wasted time.

[0004] However, the above-mentioned existing technology still has the following shortcomings when in use: 1. The distance between the two clamps cannot be adjusted, making it difficult to adapt and clamp some plastic parts with large differences in length and width, that is, it cannot clamp parts with large width; 2. There is a situation where the plastic parts are deformed when they rotate, that is, one of the clamps is in a passive rotating state, and the passively rotating clamp is prone to causing the plastic parts to twist, which will affect the quality after spraying.

[0005] Therefore, this utility model provides a fixture structure for spraying plastic products. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a clamping structure for spraying plastic products, thereby solving the problems mentioned in the background art. This utility model has the function of adjusting the distance between two slotted clamps, which is suitable for clamping plastic parts with different shapes and sizes; it also has the function of simultaneously driving the two slotted clamps to rotate, which can effectively prevent the plastic parts from twisting and deforming.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixture structure for spraying plastic products, comprising a base and a grooved fixture. Two vertically distributed limiting plates are mounted on the base. A connecting shaft is mounted on the grooved fixture. A rotating sleeve is passed through one side of each limiting plate. The rotating sleeves on the two limiting plates are coaxial. One end of the connecting shaft is fitted into the rotating sleeve and is axially slidingly engaged. Cylinders for controlling the axial movement of the connecting shaft are mounted on the opposing surfaces of both limiting plates. A gantry frame is laterally slidably connected between the two limiting plates. Two side rods on the gantry frame respectively engage with the rotating sleeves on the two limiting plates. A control assembly for controlling the sliding of the gantry frame is mounted on the base.

[0008] Furthermore, a grooved frame is welded to the back of the limiting plate, and the cylinder is fixedly mounted at one end of the grooved frame with its output shaft and one end of the connecting shaft rotatably connected.

[0009] Furthermore, a row of toothed grooves is provided on one side of the side rod, and a gear that meshes with the toothed grooves is fixedly sleeved on the rotating sleeve.

[0010] Furthermore, the control assembly includes a control motor and a transmission screw. A vertical plate is welded to the top of the base. The control motor is fixedly mounted on one side of the vertical plate, and its output shaft is fixedly connected to one end of the transmission screw. The transmission screw and the crossbeam on the portal frame are screwed together through it.

[0011] Furthermore, a guide shaft is welded to the other side of the upright plate, and a guide hole is provided on one side of the crossbeam near both ends and fitted onto the guide shaft.

[0012] Furthermore, limiting sleeves that slide in conjunction with the side rods are welded to the opposite sides of the two limiting plates.

[0013] Furthermore, the bottom of the base is provided with guide wheels.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by setting a rotating sleeve that slides axially with the connecting shaft on the limiting plate, and then setting a cylinder on the outside of the limiting plate to control the axial movement of the connecting shaft, the position of the grooved clamp connected to the connecting shaft is adjustable, which facilitates the clamping of plastic parts with large differences in shape and size, and improves the applicability of this structure.

[0016] 2. In this utility model, by setting a gantry frame on the base, the two side plates on the gantry frame are respectively engaged with the rotating sleeves connected to the two slotted clamps. Thus, when the gantry frame moves, the rotating sleeves can simultaneously drive the two slotted clamps to rotate. This arrangement eliminates the problem of twisting when the plastic parts are tightened and rotated, and improves the quality after surface spraying. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a clamp structure for spraying plastic products, including a base 1 and a groove clamp 2. Both the base 1 and the groove clamp 2 adopt the structure mentioned in the patent documents in the background art. The base 1 is provided with two vertically distributed limiting plates 11, and the groove clamp 2 is provided with a connecting shaft 21.

[0023] In this technical solution, a rotating sleeve 3 is provided through one side of the limiting plate 11. The rotating sleeves 3 on the two limiting plates 11 are coaxial. One end of the connecting shaft 21 is sleeved in the rotating sleeve 3 and is axially slidingly fitted. One rotating sleeve 3 corresponds to one slotted clamp 2. When the rotating sleeve 3 rotates, it can drive the corresponding slotted clamp 2 to rotate. The opposing surfaces of the two limiting plates 11 are provided with cylinders 4 for controlling the axial movement of the connecting shaft 21. When the cylinders 4 are activated, they can drive the slotted clamp 2 to move its position through the connecting shaft 21, thereby adjusting the distance between the two slotted clamps 2, which is suitable for clamping plastic parts of different specifications. In a specific implementation, preferably, a slotted frame 111 is welded to the back of the limiting plate 11. The cylinder 4 is fixedly installed at one end of the slotted frame 111 and its output shaft is rotatably connected to one end of the connecting shaft 21.

[0024] Furthermore, a gantry frame 5 is laterally slidably connected between the two limiting plates 11. The gantry frame 5 can be in a horizontal state. Two side rods 51 on the gantry frame 5 respectively engage with rotating sleeves 3 on the two limiting plates 11. In a specific implementation, preferably, a row of toothed grooves 511 is opened on one side of the side rod 51, and a gear 31 that meshes with the toothed grooves 511 is fixedly sleeved on the rotating sleeve 3. When the side rod 51 moves, it drives the gear 31 to rotate, which in turn drives the rotating sleeve 3 to rotate. The two limiting plates 11 have limiting sleeves 112 welded to the opposite sides, which slide and engage with the side rod 51. The function of the limiting sleeves 112 is to improve the smoothness of the sliding of the side rod 51. When the gantry frame 5 moves laterally, the two side rods 51 on it can simultaneously drive the two rotating sleeves 3 to rotate, which in turn drives the two slotted clamps 2 to rotate. This arrangement prevents the plastic parts from twisting and deforming, improving the quality of subsequent surface spraying. The base 1 is provided with a control assembly 6 for controlling the sliding of the gantry frame 5.

[0025] Specifically, the control assembly 6 includes a control motor 61 and a transmission screw 62. A vertical plate 12 is welded to the top of the base 1. The control motor 61 is fixedly mounted on one side of the vertical plate 12, and its output shaft is fixedly connected to one end of the transmission screw 62. The transmission screw 62 and the crossbeam 52 on the portal frame 5 are connected by a through screw. When the transmission screw 62 rotates, the crossbeam 52 will move by the screwing action, which in turn can drive the portal frame 5 to translate.

[0026] Furthermore, a guide shaft 121 is welded to the other side of the upright plate 12, and a guide hole 521 is opened on one side of the crossbeam 52 near both ends and fitted onto the guide shaft 121. The purpose of this arrangement is to improve the stability of the translation of the portal frame 5.

[0027] In this embodiment, the bottom of the base 1 is provided with guide wheels 7. There are four guide wheels 7, which are distributed at the corners of the base. This arrangement facilitates the transfer of this structure.

[0028] Working principle: When a long plastic part needs to be clamped, the cylinder 4 is started to drive the connecting shaft 21 to move outward. At this time, the distance between the clamping slots on the two slotted clamps 2 increases, and the two ends of the plastic part are inserted into the clamping slots. Then, the slotted clamps 2 are controlled to clamp the plastic part. When the plastic part needs to be flipped, the control motor 61 is started, the transmission screw 62 rotates, and the crossbeam 52 moves horizontally. At this time, the side rod 51 will drive the gear 31 to rotate through meshing. The rotating sleeve 3 rotates and drives the connecting shaft 21 to rotate. Finally, the two slotted clamps 2 rotate synchronously to realize the overall rotation control of the plastic part.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
