Description

Technical Field

[0001] This application relates to the field of jigs, and particularly to a turnover loading sandblasting jig. Background Art

[0002] Sandblasting is an important process in workpiece machining. It cleans, deburrs, or increases the surface roughness of the workpiece by spraying abrasives at high speed. During the sandblasting process, using a jig is crucial to ensure the correct fixation and efficient processing of the workpiece. Before starting sandblasting, the operator needs to first take out the workpiece from the storage state. Usually, the workpieces are placed on multiple stacked loading trays. The loading trays usually have multiple placement positions, and each placement position is used to place one workpiece. However, when the loading trays are stacked, due to the weight, the upper loading tray will exert pressure on the workpieces in the lower loading tray, which easily causes the workpieces to get stuck in the placement positions of the loading tray. This jamming phenomenon is caused by the friction between the workpiece and the loading tray and the too-tight fit between the shape of the workpiece and the placement position. In order to take out the workpiece from the loading tray and place it on the sandblasting panel, the operator needs to manually operate one by one. Frequent manual operations increase the labor intensity of the operator, easily cause fatigue, and it is difficult to ensure that each workpiece is accurately placed, directly affecting the sandblasting quality. Summary of the Utility Model

[0003] This application aims to solve at least one of the technical problems existing in the prior art.

[0041] Referring to Figures 1 to 9 , in some specific embodiments, the turnover loading sandblasting jig includes:

[0042] A sandblasting panel 200, on one side of the sandblasting panel 200, a plurality of sandblasting placement grooves 230 are provided, and the sandblasting placement grooves 230 are used for placing workpieces 250;

[0043] A loading tray 300, detachably installed on one side of the sandblasting panel 200, on one side of the loading tray 300, a placement surface 330 is provided, on the placement surface 330, a plurality of placement positions 320 are provided, and the plurality of placement positions 320 respectively face the plurality of sandblasting placement grooves 230.

On one side of the material ejecting seat 400, a plurality of material ejecting columns 410 are provided, and the plurality of material ejecting columns 410 respectively face the material ejecting grooves 322 of the plurality of placement positions 320, so that the material ejecting columns 410 penetrate through the material ejecting grooves 322, and the workpieces 250 in the placement positions 320 fall into the sandblasting placement grooves 230.

[0045] It can be understood that the workpiece 250 is first stored on the placement position 320 of the loading tray 300. At this time, the placement surface 330 of the loading tray 300 faces upward. In order to prevent some workpieces 250 from falling during the flipping process, the sandblasting panel 200 needs to be flipped first and installed on the placement surface 330 of the loading tray 300. At this time, the sandblasting placement groove 230 of the sandblasting panel 200 faces downward, so that multiple placement positions 320 respectively face multiple sandblasting placement grooves 230.

And through the insertion of the positioning support columns 110 and the positioning seats 210, the position of the sandblasting panel 200 on the sandblasting base 100 is fixed, increasing the stability of the whole sandblasting panel 200 during sandblasting and preventing the position deviation caused by vibration and other reasons during the sandblasting process of the sandblasting panel 200.

[0049] Refer to Figure 8, in some specific embodiments, a first fixing hole 111 is formed inside the positioning support column 110, a second fixing hole 112 is formed inside the sandblasting base 100, the first fixing hole 111 communicates with the second fixing hole 112, a fixing bolt 113 is inserted into the second fixing hole 112, and the fixing bolt 113 is in threaded engagement with the first fixing hole 111.

[0050] It can be understood that when the fixing bolt 113 passes through the second fixing hole 112 and is tightened, it will generate frictional force with the first fixing hole 111, thereby fixing the position of the positioning support column 110 on the sandblasting base 100. The threaded engagement of the fixing bolt 113 can provide sufficient clamping force to prevent the positioning support column 110 from loosening due to vibration during the sandblasting process.

[0051] Refer to Figures 5 to 9 , in some specific embodiments, an installation convex plate 240 is provided on the outer edge of the sandblasting panel 200, a positioning pin 241 is provided on one side of the installation convex plate 240, a positioning plate 350 is provided on the outer edge of the loading tray 300, a positioning socket 351 is formed inside the positioning plate 350, and the positioning pin 241 is inserted into the positioning socket 351.

[0053] Refer to Figures 8 to 9 , in some specific embodiments, a positioning plug 242 is provided at one end of the positioning pin 241, the shape of the positioning plug 242 is a cone, and the positioning plug 242 is inserted into the positioning socket 351.

[0054] It can be understood that the conical shape enables the conical tip of the positioning plug 242 to first contact the positioning socket 351 when the positioning plug 242 is inserted into the positioning socket 351, gradually guiding the entire plug into the positioning socket 351, which helps to reduce friction and damage during the insertion process. And in the case of limited space or poor visibility, the guiding function of the cone enables the operator to more easily insert the positioning pin 241 into the positioning socket 351.

[0055] Refer to Figures 5 to 9, in some specific embodiments, a plurality of limiting seats 310 are provided on the outer edge of the loading tray 300.

[0056] It can be understood that the first limiting convex plates 311 of the plurality of limiting seats 310 surround each other to form a first limiting interval 313. When the sandblasting panel 200 is inserted into the first limiting interval 313, the first limiting interval 313 limits the movement range of the loading tray 300 on the sandblasting panel 200, ensuring that the loading tray 300 does not exceed the predetermined position and improving the accuracy and efficiency of the sandblasting operation.

[0057] Refer to Figures 5 to 9 , in some specific embodiments, a second limiting convex plate 312 is provided on the other side of the limiting seat 310, and the second limiting convex plate 312 extends to the blanking surface 340. The second limiting convex plates 312 of the plurality of limiting seats 310 surround to form a second limiting interval 314, and the blanking seat 400 is inserted into the second limiting interval 314.

[0058] It can be understood that the second limiting convex plate 312 extends to the blanking surface 340, so that the second limiting convex plates 312 of the plurality of limiting seats 310 surround to form a second limiting interval 314. The second limiting interval 314 and the blanking seat 400 form a plug-in fit, increasing the limitation of the position of the loading tray 300 and preventing the loading tray 300 from shifting during the blanking process.

[0059] Refer to Figure 5 , in some specific embodiments, a plurality of limiting seats 321 are provided on one side of the placement position 320. The limiting seats 321 are deformable. An installation groove 251 is formed on one side of the workpiece 250. The shape surrounded by the plurality of limiting seats 321 matches the installation groove 251 of the workpiece 250, and the plurality of limiting seats 321 are clamped with the installation groove 251 of the workpiece 250.

[0060] It can be understood that the shape of the limiting seat 321 matches the installation groove 251 of the workpiece 250, which enables the workpiece 250 to be stably placed on the placement position 320 and ensures the stability of the position of the workpiece 250 during storage.
