Description

Technical Field

[0001] The utility model belongs to the field of industrial processing, in particular to a device for quickly positioning the center of a casting rod. Background Art

[0002] When finishing the cast rod, it is necessary to locate the center of the cast rod so as to align the cast rod car body. The traditional method of locating the center is to use the center hole of the cast rod section template to locate the center. Many templates need to be made and it takes a long time to align the center. Utility Model Content

[0003] The technical problem to be solved by the utility model is that in the prior art, when casting rods for car skins, the center of the circle needs to be positioned, which is time-consuming and labor-intensive due to the large number of casting rod diameter specifications and the large number of positioning templates.

[0004] In order to solve the above technical problems, a technical solution provided by the utility model is:

[0005] A device for quickly locating the center of a cast rod comprises a base and a center indicator plate, wherein the base is an L-shaped base, and the center indicator plate is an angle indicator plate, one end of the angle indicator plate is fixedly overlapped with one end of the L-shaped base, and the other end of the angle indicator plate is located on the angular bisector of the 90° angle on the L-shaped base.

[0006] Furthermore, the L-shaped base includes a horizontal plate and a vertical plate, the angle between the horizontal plate and the vertical plate is 90 degrees, and the horizontal plate and the vertical plate are an integrated structure.

[0007] Furthermore, the angle indicating plate comprises a base plate and an indicating plate, the angle between the base plate and the indicating plate is 45°, and the length of the indicating plate is greater than the length of the base plate.

[0008] Furthermore, the bottom plate is riveted to the cross plate by rivets, which will not cause deformation of the bottom plate and the cross plate.

[0009] Furthermore, the outer wall of the indicator plate is located on the bisector of the 90° angle of the L-shaped base. When drawing lines, it is not easy to draw obliquely and the lines can be drawn smoothly by drawing on the upper end of the outer wall of the indicator plate.

[0010] Furthermore, the indicator plate is provided with a scale, which is convenient for measuring the diameter of the cast rod during the process of determining the center of the circle, and is convenient for counting the size of the measured cast rod.

[0011] The beneficial effects of the utility model are:

[0012] 1. This device is used to locate the center of the cast rod. As long as the radius of the cast rod is not greater than the length of the indicator plate, the center of the cast rod can be quickly located according to the indication of the indicator plate. This not only greatly reduces the number of positioning template workpieces, but also greatly improves the efficiency of locating the center of the cast rod during the car body, saving labor and material costs.

[0013] 2. In this device, after the center of the cast rod is located, it is necessary to count the cast rods. A scale is set on the indicator board so that when the center of the circle is located, the radius size of the cast rod at the center of the circle can be checked at the same time. The size of the cast rod can be known without checking the cast rod record, which is convenient for counting the located cast rods and improving the efficiency of locating the center of the cast rod.

[0025] like Figure 1-4 As shown, a device for quickly locating the center of a cast rod includes a base and a center indicator plate. The base is an L-shaped base, and the L-shaped base includes a horizontal plate 1 and a vertical plate 2. The angle between the horizontal plate 1 and the vertical plate 2 is 90°, and the horizontal plate 1 and the vertical plate 2 are an integrated structure.

[0026] The dimensions of the horizontal board 1 and the vertical board 2 can be made accordingly as needed. For example, the width of the horizontal board 1 and the vertical board 2 is 40 mm, the length of the horizontal board inner wall 4 and the length of the vertical board inner wall 6 are both 180 mm, and the length of the horizontal board outer wall 5 and the length of the vertical board outer wall 7 are both 220 mm.

[0027] The inner wall 4 of the horizontal plate intersects with the inner wall 6 of the vertical plate, and the outer wall 5 of the horizontal plate intersects with the outer wall 7 of the vertical plate, both at an angle of 90°.

[0028] The center indicator plate is an angle indicator plate, which includes a base plate 8 and an indicator plate 9. The angle between the base plate 8 and the indicator plate 9 is 45°. The length of the indicator plate 9 is greater than that of the base plate 8. The base plate 8 and the indicator plate 9 are an integrated structure.

[0029] The sizes of the base plate 8 and the indicator plate 9 can be made accordingly as needed. For example, the widths of the base plate 8 and the indicator plate 9 are both 40 mm, the length of the base plate inner wall 10 is 123.43 mm, the length of the base plate outer wall 11 is 220 mm, the length of the indicator plate inner wall 12 is 203.43 mm, and the length of the indicator plate outer wall 13 is 300 mm.

[0030] The bottom plate inner wall 10 intersects with the indicator plate inner wall 12 at an angle of 45°, and the bottom plate outer wall 11 intersects with the indicator plate outer wall 13 at an angle of 45°.

[0031] The bottom plate 8 overlaps with the transverse plate 1: the bottom plate outer wall 11 overlaps with the transverse plate outer wall 5, the bottom plate inner wall 10 overlaps with the transverse plate inner wall 4, and corresponding rivet holes are provided on the bottom plate 8 and the transverse plate 1, and the bottom plate 8 is riveted to the transverse plate 1 through the rivet holes using rivets 14.

[0032] The outer wall 13 of the indicator plate is located on the bisector of the 90° angle on the L-shaped base.

[0033] During operation, the device is placed at the end of the cast rod 3, and the inner wall 4 of the horizontal plate and the inner wall 6 of the vertical plate coincide with the tangent line of the cast rod 3. At this time, the first auxiliary line is drawn with a marking pen at the position of the outer wall 13 of the indicator plate, and then the base is rotated so that the inner wall 4 of the horizontal plate and the inner wall 6 of the vertical plate on it coincide with the other two tangent lines of the cast rod 3. At this time, the second auxiliary line is drawn with a marking pen at the position of the outer wall 13 of the indicator plate, and the intersection of the first auxiliary line and the second auxiliary line is the center point of the circle. Positioning the center of the circle in this way not only greatly reduces the number of positioning template workpieces, but also greatly improves the efficiency of positioning the center of the circle when the cast rod 3 is on the wagon, saving labor and material costs. Embodiment 2

[0034] like Figure 1-5 As shown, the difference between this embodiment and the first embodiment is that a scale 15 is provided on the indicator plate 9, so that when locating the center of the circle, the radius size of the cast rod 3 at the located center of the circle can be checked at the same time, and the size of the cast rod 3 can be known without checking the cast rod 3 record, which is convenient for counting the located cast rods 3 and improving the efficiency of locating the center of the circle of the cast rod 3.

[0035] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
