[0024] The following is for reference. Figures 1 to 5 The sandblasting fixture of this application is described in detail.

[0025] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 According to an embodiment of the present invention, a sandblasting fixture includes a lower fixture body 100 and an upper fixture body 200. The lower fixture body 100 is provided with a processing area 101 for placing a workpiece. The processing area 101 is provided with a first positioning post 110 for positioning the workpiece. A flexible protective layer 111 is sleeved on the surface of the first positioning post 110. A flexible isolation layer 120 is laid in the processing area 101, and the flexible isolation layer 120 is used to support the workpiece. The upper fixture body 200 includes a frame 210 and a limiting wire 220. The frame 210 is detachably connected to the lower fixture body 100. The limiting wire 220 is installed on the frame 210 and is used to prevent the workpiece in the processing area 101 from moving upward.

[0026] For example, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the sandblasting fixture includes a lower fixture body 100 and an upper fixture body 200. The lower fixture body 100 is provided with a processing area 101, and a vertically extending first positioning post 110 is provided in the processing area 101. A flexible protective layer 111 is sleeved on the surface of the first positioning post 110, and a flexible isolation layer 120 is laid on the surface of the processing area 101. The upper fixture body 200 is located on the upper side of the lower fixture body 100. The upper fixture body includes a frame 210 and a limiting wire 220. The two ends of the limiting wire 220 are connected to the frame 210, and the frame 210 is detachably connected to the edge of the lower fixture body 100.

[0027] Furthermore, before sandblasting the workpiece, the operator can place the workpiece in the processing area 101 and make the first positioning post 110 pass through the positioning hole on the workpiece. Then, the operator can connect the frame 210 to the lower body 100 of the fixture so that the limiting wire 220 abuts against the upper surface of the workpiece. After that, the sandblasting equipment can complete the sandblasting of the workpiece normally.

[0028] It is understandable that by laying a flexible isolation layer 120 in the processing area 101, the flexible isolation layer 120 can separate the workpiece from the lower body of the fixture 100 during sandblasting, thereby protecting the workpiece and reducing scratches on the workpiece by the lower body of the fixture 100.

[0029] It is understandable that by providing a flexible protective layer 111 on the first positioning post 110, even if the workpiece vibrates under the impact of the abrasive during the sandblasting process, the flexible protective layer 111 can protect the workpiece and reduce the scratches caused by the first positioning post 110 on the workpiece due to the space between the first positioning post 110 and the workpiece.

[0030] Understandably, the limiting wire 220 is designed to not only properly contact the workpiece downwards, thus reducing the vertical vibration of the workpiece during sandblasting, but also reduce the probability of the workpiece detaching from the first positioning post 110 in the vertical direction. At the same time, the contact area between the limiting wire 220 and the workpiece is small, resulting in less scratching of the workpiece by the limiting wire 220, thereby reducing the scratching of the workpiece by the sandblasting body.

[0031] In some embodiments of this utility model, multiple sets of first positioning post groups are arranged at intervals along the first horizontal direction in the processing area 101. Each set of first positioning post groups includes multiple first positioning posts 110 distributed at intervals along the second horizontal direction. The first horizontal direction and the second horizontal direction are arranged at a certain angle, and the number of first positioning posts 110 in each set of first positioning post groups is different in the same processing area 101.

[0032] For example, such as Figure 2 As shown, the first horizontal direction is the left-right direction, and the second horizontal direction is the front-back direction. There are two sets of first positioning post groups in the processing area 101 along the left-right direction. The first positioning post group on the left side includes three first positioning posts 110 that are distributed at intervals along the front-back direction, and the first positioning post group on the right side includes two first positioning posts 110 that are distributed at intervals along the front-back direction.

[0033] It is understandable that within the same processing area 101, since the number of first positioning posts 110 in each group of first positioning posts is different, when the workpiece is placed in the processing area 101, it can prevent the workpiece from being mistakenly placed in the processing area 101, so that the workpiece can be placed in the processing area 101 in the correct posture.

[0034] In a further embodiment of the present invention, the lower body 100 of the fixture is provided with a plurality of processing areas 101, which are arranged in an array, and each processing area 101 is provided with a plurality of first positioning column groups.

[0035] It is understood that by setting multiple processing areas 101 on the lower body 100 of the fixture, and each processing area 101 can hold a workpiece, multiple workpieces can be placed on the sandblasting fixture of this application at the same time. When the sandblasting fixture of this application is applied to the sandblasting equipment, the operator can load the sandblasting fixture once, so that the sandblasting equipment can complete the sandblasting processing of multiple workpieces, thereby making the working efficiency of the sandblasting equipment higher.

[0036] In some embodiments of this utility model, reference is made to Figure 3 The upper end of the first positioning post 110 is provided with a tapered first guide slope 112, which is used to guide the first positioning post 110 to pass through the positioning hole on the workpiece.

[0037] It is understandable that by setting a tapered first guide slope 112 at the upper end of the first positioning post 110, when the worker drives the workpiece downward to approach the lower body 100 of the fixture, even if the workpiece is offset in the horizontal direction, after the edge of the positioning hole abuts against the first guide slope 112, the workpiece can be offset in the horizontal direction under the guiding action of the first guide slope 112, so that the first positioning post 110 and the positioning hole are coaxial, and thus the first positioning post 110 can be smoothly inserted into the positioning hole.

[0038] In some embodiments of this utility model, the frame 210 is detachably connected to the lower body 100 of the fixture via a positioning structure.

[0039] It is understandable that by setting up a positioning structure, the positioning structure can not only realize the installation of the frame 210 on the lower body 100 of the fixture, but also position the frame 210 when it is installed on the lower body 100 of the fixture, so as to improve the installation accuracy of the frame 210 on the lower body 100 of the fixture.

[0040] In a further embodiment of this utility model, reference is made to... Figure 2 and Figure 5 The positioning structure includes a second positioning post 130 disposed on the lower body 100 of the fixture, and a connecting hole 230 adapted to the second positioning post 130 is provided on the frame 210.

[0041] It is understandable that when the upper body 200 of the fixture is installed on the lower body 100 of the fixture, the operator can insert the second positioning post 130 into the connecting hole 230, thereby enabling the upper body 200 of the fixture to be quickly positioned and installed on the lower body 100 of the fixture.

[0042] In some embodiments of this utility model, reference is made to Figure 4 The upper end of the second positioning post 130 is provided with a second guide slope 131, which is used to guide the second positioning post 130 into the connecting hole 230.

[0043] It is understandable that, through the second guide slope 131 set at the upper end of the second positioning post 130, when the worker drives the upper body 200 of the fixture downward to approach the lower body 100 of the fixture, even if the upper body 200 of the fixture is offset in the horizontal direction, after the edge of the connecting hole 230 abuts against the second guide slope 131, under the guiding action of the second guide slope 131, the upper body 200 of the fixture can be offset in the horizontal direction, so that the second positioning post 130 and the connecting hole 230 are coaxial, and thus the second positioning post 130 can be smoothly inserted into the connecting hole 230.

[0044] In some embodiments of this utility model, the lower body 100 of the fixture is provided with a plurality of second positioning posts 130 spaced circumferentially along its edge, and the frame 210 is provided with a plurality of connecting holes 230 corresponding to the second positioning posts 130.

[0045] For example, such as Figure 2 As shown, a second positioning post 130 is provided on each of the left and right edges of the lower body 100 of the fixture, and two connecting holes 230 are provided on the frame 210 corresponding to the second positioning posts 130. Therefore, when connecting the lower body 100 and the upper body 200 of the fixture, the two second positioning posts 130 are respectively inserted into the two connecting holes 230.

[0046] It is understandable that by setting multiple second positioning posts 130 on the lower body 100 of the fixture and setting multiple connecting holes 230 on the frame 210 corresponding to the second positioning posts 130, the installation accuracy of the upper body 200 on the lower body 100 of the fixture is higher.

[0047] In some embodiments of this utility model, the limiting wire 220 extends along the first horizontal direction, and multiple limiting wires 220 are spaced apart along the second horizontal direction, with the second horizontal direction and the first horizontal direction spaced apart at a certain angle.

[0048] For example, such as Figure 5 As shown, the first horizontal direction is the left-right direction, the second horizontal direction is the front-back direction, the limiting wire 220 extends along the left-right direction, the left and right ends of the limiting wire 220 are respectively connected to the frame 210, and multiple limiting wires 220 are spaced apart along the front-back direction.

[0049] It is understandable that by setting multiple limiting wires 220, the upper body 200 of the fixture can vertically limit multiple workpieces on the lower body 100 of the fixture, and the operator can adjust the interval between two adjacent limiting wires 220 to achieve the vertical limitation of the same workpiece on the lower body 100 of the fixture by multiple limiting wires 220 working together.

[0050] The sandblasting equipment provided according to the second aspect of the present invention includes the sandblasting fixture provided in the first aspect of the present invention.

[0051] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
