Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting jigs, in particular to a segmented positioning sandblasting jig. Background Art

[0002] The segmented positioning sandblasting jig is a specially designed tool for segmented positioning and precise sandblasting of the workpiece surface during the sandblasting process. This jig usually consists of a support platform with multiple positioning columns and sand leakage holes distributed on it. The positioning columns are used to ensure that the workpiece can be accurately fixed on the jig during sandblasting, while the sand leakage holes allow the sand or abrasive to be sprayed evenly onto the workpiece surface. The key feature of the segmented positioning sandblasting jig is that it can divide the workpiece surface into multiple independent areas and allow each area to be sandblasted independently. Through precise positioning and support design, the jig can ensure that the workpiece remains stable during the sandblasting process, reduce movement and shaking, thereby improving the accuracy and efficiency of sandblasting.

[0003] At present, when sandblasting products, in order to fix and position the products, fixed columns are generally used to fix them. Although the fixed columns have good stability, part of the product will be blocked by the fixed columns, resulting in poor sandblasting of the product, thus affecting the increase of the defective rate of sandblasting of the product. Therefore, a segmented positioning sandblasting fixture is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-6 The segmented positioning sandblasting jig in this embodiment includes a front jig 1, and a positioning mechanism is provided on the outer wall of the front jig 1.

[0027] Fifty-four second positioning grooves 10 are formed on the front outer wall of the front fixture 1 .

[0028] The positioning mechanism includes a reverse jig 2 movably mounted on the front outer wall of the front jig 1, a number of fifty-four first positioning grooves 8 are opened on the front side of the reverse jig 2, a number of fifty-four clamping holes 9 are opened on the side of the reverse jig 2 close to the front jig 1, the first positioning grooves 8 are connected with the clamping holes 9, a positioning column 3 is fixedly mounted on the front outer wall of the front jig 1, the number of the positioning columns 3 is twelve, and the twelve positioning columns 3 are symmetrically distributed on the front outer wall of the front jig 1, a first filling seat 4 is fixedly mounted on the front outer wall of the front jig 1, a second filling seat 5 is fixedly mounted on the side of the reverse jig 2 close to the front jig 1, and the number of the second filling seats 5 is four.

[0029] The front outer wall of the front jig 1 is respectively fixedly installed with a first arc-shaped positioning seat 6 and a third arc-shaped positioning seat 11. The first arc-shaped positioning seat 6 is fixedly installed on the side of the reverse jig 2 close to the front jig 1 and there are forty-eight of them. The number of the first arc-shaped positioning seats 6 is forty-five. The outer wall of the first arc-shaped positioning seat 6 is provided with two positioning arc-shaped grooves. The number of the first filling seats 4 is four. The first filling seat 4 is provided with a notch. The second filling seat 5 fits with the first filling seat 4 and is located in the notch.

[0030] The first filling seat 4 is provided with a first arc groove on one side close to the first arc positioning seat 6 and the third arc positioning seat 11. The number of first arc grooves provided on the first arc positioning seat 6 is two. A second arc positioning seat 7 is fixedly installed on the side of the reverse jig 2 close to the front jig 1. The number of second arc positioning seats 7 is twelve. The twelve second arc positioning seats 7 are symmetrically distributed on the dorsal outer wall of the reverse jig 2. The outer walls of the opposite sides of the two symmetrical second arc positioning seats 7 on the left and right are provided with second arc grooves.

[0031] In this embodiment, the side of the positioning post 3 away from the front fixture 1 is attached to the back outer wall of the back fixture 2 .

[0032] In this embodiment, the sum of the arcs of the two first arc-shaped grooves formed in the first arc-shaped positioning seat 6 is one quarter of the arc of a circle.

[0033] In this embodiment, the product is fixed by means of segmented positioning of the outer shape. When sandblasting the back side, two quarter arcs are used for positioning, leaving other arcs for sandblasting together with the back side. After sandblasting the back side, the jig is buckled to avoid secondary clamping. When sandblasting the front side, two quarter arcs that have been sandblasted are used for positioning, leaving other arcs for sandblasting together with the front side. In this way, all areas can be sandblasted normally.

[0034] The working principle of the above embodiment is:

[0035] First, clamp multiple products on the back jig 2, and then sandblast the back side. After the back side of the product is sandblasted, buckle the front jig 1 into the back jig 2, then turn the jig 180 degrees, take out the back jig 2, and then sandblast the front side. After the front side sandblasting is completed, the product has been completely sandblasted and then taken out from the front jig 1. At this time, the sandblasting processing of the product is completed.
