Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, and more specifically, it relates to a fixture for sandblasting metal sheets. Background Technology

[0002] Sheet metal is a thin, flat sheet of metal formed by industrial methods. Sheet metal is one of the basic forms used in metal processing, and it can be cut and bent into various shapes. Countless everyday items are made of sheet metal, and sheet metal parts often require sandblasting during processing.

[0003] For example, a metal sandblasting fixture disclosed in authorization announcement number CN219854050U can achieve sandblasting of both sides of a metal part in one clamping by flipping the layer plate, which reduces the cumbersome process.

[0004] In the above, the right-angled area inside the fixture forms a sand accumulation zone, which leads to sand waste and low recycling rate due to the mixing of sand and impurities. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a more cost-effective clamp for sandblasting metal plates.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A clamp for sandblasting metal sheets includes a base plate with a space inside. Two mounting plates are disposed within the base plate, and both mounting plates are hinged to the side wall of the base plate. There is a groove between the two mounting plates. A push cylinder is located below the two mounting plates, positioned between them, with its output end contacting the two mounting plates. A negative pressure recovery channel is provided on the bottom surface of the base plate, and a collection chamber is located on the lower end face of the base plate, communicating with the transverse groove. The collection chamber is equipped with a filter plate, and a pushing mechanism is placed on the filter plate. The pushing mechanism includes two sets of lead screw assemblies and a cleaning plate placed between the two lead screw assemblies. The lower end face of the cleaning plate abuts against the upper end face of the filter plate.

[0007] The present invention is further configured such that: the lead screw assembly includes a ball screw, a guide rod, a drive motor and a fixed seat; the two ends of the guide rod are connected to the inner wall of the collection chamber; the fixed seat and the drive motor are placed at the two ends of the guide rod; the ball screw is placed between the fixed seat and the drive motor; the guide rod is placed on one side of the ball screw and is arranged parallel to the ball screw; the outer peripheral walls of the ball screw and the guide rod are fitted with slides; and the cleaning plate is connected to the two slides.

[0008] The present invention is further configured such that: a vibration motor is provided on the side wall of the base plate, and the output end of the vibration motor abuts against the side wall of the mounting plate.

[0009] The present invention is further configured such that the cross-section of the cleaning plate is arc-shaped.

[0010] The present invention is further configured such that the bottom surface of the space has a circular chamfer.

[0011] The present invention is further configured such that: a ventilation opening is provided on one side of the collection chamber, and a fan is connected to the ventilation opening so as to create negative pressure inside the collection chamber.

[0012] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows: When cleaning sand particles from the mounting plates, which are connected by hinges, is required, the vibration motor is activated to concentrate the sand particles. Then, the push cylinder is activated to retract. Due to the hinge connection between the two mounting plates, the mounting plates rotate after the push cylinder retracts, and the sand particles flow out of the tank into the negative pressure recovery channel and into the collection chamber. The sand particles then fall onto the filter plate, and the cleaning plate applies force to make the sand particles fall into the collection chamber, thus completing the recycling of the sand particles.

Therefore, they should not be construed as limitations on this utility model.

[0017] Working principle: When it is necessary to clean the sand particles on the mounting plate 2, the vibration motor 14 is started. The vibration motor 14 vibrates and drives the mounting plate 2 to move, then the sand particles are concentrated. Then the push cylinder 4 is started, causing the push cylinder 4 to retract. Since the two mounting plates 2 are connected by a hinge, the mounting plate 2 rotates after the push cylinder 4 retracts. The sand particles flow out from the tank 3 into the negative pressure recovery channel 5 and then into the collection chamber 6. Then the sand particles fall onto the filter plate 7. Subsequently, the drive motor 11 is started. The start motor rotates and drives the ball screw 10 to rotate. The rotation of the ball screw 10 drives the slide to move. The movement of the slide drives the cleaning plate to move. The movement of the cleaning plate pushes the sand particles on the filter plate 7 until the sand particles fall to the bottom of the collection chamber 6.

[0018] like Figures 1 to 3 As shown, Includes a base plate 1, which has a space inside. The bottom surface of the space has a rounded chamfer to prevent sand from accumulating at the corners and making it difficult to clean.

[0019] The base plate 1 has two mounting plates 2 inside. Both mounting plates 2 are hinged to the side wall of the base plate 1. The side wall of the base plate 1 is equipped with a vibration motor 14. The output end of the vibration motor 14 abuts against the side wall of the mounting plate 2, so that the vibration motor 14 can drive the mounting plate 2 to vibrate and concentrate the sand particles.

[0020] The two mounting plates 2 are hinged together, and there is a groove 3 between the two mounting plates 2, from which sand particles flow out.

[0021] A push cylinder 4 is provided below the two mounting plates 2. The push cylinder 4 is placed between the two mounting plates 2. By pushing the cylinder 4 to retract, the angle of the two mounting plates 2 is changed, causing the sand particles to fall.

[0022] The bracket on the output end of the cylinder 4 abuts against the two mounting plates 2. The bottom surface of the base plate 1 is provided with a negative pressure recovery channel 5. The lower end of the base plate 1 is provided with a collection chamber 6. The collection chamber 6 is connected to the transverse groove. A vent 15 is provided on one side of the collection chamber 6. The vent 15 is connected to a fan so as to create negative pressure in the collection chamber 6, so that sand particles can be sucked into the collection chamber 6.

[0023] The collection chamber 6 is equipped with a filter plate 7, and a pushing mechanism is placed on the filter plate 7. The pushing mechanism includes a screw assembly 8 and a cleaning plate 9 placed between the screw assembly 8. The lower end face of the cleaning plate 9 abuts against the upper end face of the filter plate 7, which facilitates the cleaning of sand particles on the filter plate 7.

[0024] The drive motor 11 rotates to drive the ball screw 10 to rotate, thereby driving the slide connected to the ball screw 10 to move. Since the slide is slidably connected to the guide rod 12, the slide can move along the guide rod 12.

[0025] The cleaning plate 9 has an arc-shaped cross-section, which facilitates contact between the cleaning plate 9 and the filter plate 7.
