Abstract
Description
Technical Field
[0001] The utility model relates to the field of injection molded parts detection, in particular to a through gauge inspection tool for a car audio basin frame. Background Art
[0002] After injection molding, injection molded parts are prone to deformation during the gradual cooling process, so their size, structure, hole position, etc. need to be tested. However, due to the wide application of injection molded parts, the shapes and sizes of injection molded parts of different types of products vary greatly, and the detection of some specially designed structures is often difficult. For example, many car audio basin frames have a port on one side for electrical connection, and the port is provided with a protrusion for matching with other structures. Since the protrusion is small in size, it is difficult to detect the matching surface.
[0003] In order to solve the above problems, a Chinese utility model patent with authorization announcement number CN215676742U discloses an external hook-type through gauge for injection molded parts. While using the through end column to detect the inner hole of the workpiece port, it also uses whether the hook body can be pressed down smoothly and whether it can be accurately engaged with the protruding part to be inspected to determine whether its size is qualified. The inspection efficiency is greatly improved and the inspection accuracy can be effectively guaranteed.
[0004] However, with the continuous improvement of the structure of car audio basins, the port matching structure of many car audio basins has also changed. Figures 8-9 As shown, under the same specifications and dimensions, according to actual installation needs, some car audio basins have protrusions on the upper and lower sides of the port for matching with other structures, while Figures 10-11 As shown, some other car audio basin racks have recesses on the upper and lower sides of the port for matching with other structures. The through gauge in the CN215676742U patent is only provided with a detection hook on one side, and the detection hook at the front end of the detection hook needs to remove the fixing bolts before it can be pulled out and replaced, which is not very convenient to operate. Utility Model Content
[0005] The utility model aims to provide a through gauge inspection tool for a car audio basin frame, which can adjust the positions of the inspection hooks at the front ends of two inspection rods according to the object to be inspected (protrusion or recess), so as to meet different inspection needs, and the operation is also simple and convenient.
[0006] The purpose of this utility model is achieved through the following technical solutions:
[0007] A through gauge inspection tool for a car audio basin frame comprises a detection seat body, a detection rod and a through end column, wherein the through end column is arranged at the front end of the detection seat body, two detection rods are rotatably arranged on both sides of the detection seat body, and the front ends of the two detection rods are provided with detection hooks, springs are arranged on both sides of the detection seat body, and the rear part of the detection rod is elastically supported by the spring on the corresponding side, the front end of the detection rod is provided with an adjustment slot, the rear side of the detection hook is provided with an engaging slider embedded in the adjustment slot, a locking threaded hole is provided on one side of the front end of the detection rod, and a locking bolt is inserted in the locking threaded hole, and a scale line is provided at the front end of the detection rod.
[0008] The detection seat body is provided with seat body slots on both sides, and the seat body slots are provided with seat body spring holes at the bottom, and the detection rod is provided with a detection rod spring hole on the lower side. One end of the spring supporting the detection rod is provided in the corresponding seat body spring hole, and the other end is provided in the corresponding detection rod spring hole.
[0009] The two sides of the detection seat body are provided with a first spring and a second spring respectively supporting different positions of the corresponding side detection rods.
[0010] A socket is provided at the front end of the detection seat body, an insert block is provided at the rear end of the through-end column, and the insert block is inserted into the socket.
[0011] The insert block is provided with a fixing threaded hole, and a through hole is provided on one side of the front end of the detection seat body. When the insert block is fully inserted into the socket, the fixing bolt passes through the through hole and is inserted into the fixing threaded hole on the insert block.
[0012] A handle is provided at the rear end of the detection seat body.
[0013] The handle is connected to the rear end of the detection seat body through a double-headed screw.
[0014] The advantages and positive effects of the utility model are:
[0015] 1. The utility model can adjust the positions of the detection hooks at the front ends of the two detection rods according to the object to be detected (protrusion or recess), so as to meet different detection needs. When the upper and lower sides of the port to be detected are protrusions, the two detection hooks are moved outward to increase the distance between them. When the upper and lower sides of the port to be detected are recesses, the two detection hooks are moved inward to reduce the distance between them.
[0016] 2. The operation of the utility model is also simple and convenient.

DETAILED DESCRIPTION
[0029] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0030] like Figures 1 to 7 As shown, the utility model comprises a detection seat body 2, a detection rod 1 and a through-end column 5, wherein the through-end column 5 is arranged at the front end of the detection seat body 2, two detection rods 1 are rotatably arranged on both sides of the detection seat body 2, and the front ends of the two detection rods 1 are both provided with an adjustable detection hook 6. Figure 7 As shown, springs are provided on both sides of the detection seat 2, and the rear part of the detection rod 1 is elastically supported by the springs on the corresponding sides. When the utility model is used, the operator first adjusts the positions of the detection hooks 6 of the two detection rods 1 according to the conditions of the object to be detected. After the adjustment, the operator presses the detection rods 1 on both sides to make the two detection hooks 6 at the front end in an open state, and then inserts the through-end terminal column 5 into the port of the car audio basin rack to be detected. If the through-end terminal column 5 can be inserted smoothly, the port inner hole detection is qualified, otherwise it is unqualified. After the through-end terminal column 5 is inserted, the operator releases the detection rods 1 on both sides, and the detection rods 1 on both sides automatically return to their horizontal original positions under the action of the springs. If the detection hook 6 at the front end of the detection rod 1 cannot fall completely, the detection is unqualified. Then the operator pulls the detection seat 2 backward horizontally. If the detection hook 6 can fit with the corresponding protrusion 10 or recess 11 and cannot be pulled out, the detection is qualified. If the detection hook 6 is disengaged and separated from the corresponding protrusion 10 or recess 11, the detection is unqualified. In addition, Figure 1 As shown, when the two detection hooks 6 move outwards and the distance between them increases, the utility model is used to detect Figures 8-9 Is the protrusion 10 on the port of the car audio basin frame shown in the figure qualified? Figures 2-3 As shown, when the two detection hooks 6 move inwards and the distance between them is reduced, the utility model can be used to detect Figures 10-11 The notch 11 on the port of the automobile basin frame shown in the figure is qualified. The front end of the detection rod 1 is provided with a scale line 7 to assist the operator to accurately adjust the opening and closing movement distance of the detection hook 6 according to the situation of the object to be detected.
[0031] like Figures 4-5 As shown, in this embodiment, the front end of the detection rod 1 is provided with an adjustment slot 101, and the rear side of the detection hook 6 is provided with an engaging slider 603 embedded in the adjustment slot 101. A locking threaded hole 102 is provided on one side of the front end of the detection rod 1, and a locking bolt 601 is inserted in the locking threaded hole 102. When the position of the detection hook 6 needs to be adjusted, Figure 5As shown, the operator loosens the locking bolt 601 outwards, and the engaging slider 603 can move freely along the adjusting slot 101. When the position of the detection hook 6 is determined, the operator tightens the locking bolt 601 inwards to make the locking bolt 601 cooperate with the groove wall on the other side of the adjusting slot 101 to clamp and fix the engaging slider 603, that is, fix the position of the detection hook 6, or the engaging slider 603 is also provided with a screw hole for the locking bolt 601 to be inserted to fix the position of the detection hook 6.
[0032] like Figure 1 and Figure 7 As shown, in this embodiment, seat grooves 202 are provided on both sides of the detection seat body 2, and seat spring holes are provided at the bottom of the seat grooves 202, and a detection rod spring hole is provided on the lower side of the detection rod 1, and one end of the spring supporting the detection rod 1 is provided in the corresponding seat spring hole, and the other end is provided in the corresponding detection rod spring hole.
[0033] like Figure 7 As shown, in this embodiment, the first spring 9 and the second spring 8 are provided on both sides of the detection seat body 2 to respectively support different positions of the corresponding side detection rod 1. When the utility model is used, the operator can press different parts of the detection rod 1 according to different detection objects (protrusions 10 or recesses 11) to make the opening angles of the two detection hooks 6 on the front side different. When detecting the recess 11, the operator can press the middle position of the detection rod 1 corresponding to the first spring 9. At this time, the opening angle of the two detection hooks 6 on the front side is relatively small. When detecting the protrusion 10, the detection personnel can press the rear end position of the detection rod 1 corresponding to the second spring 8. At this time, the opening angle of the two detection hooks 6 on the front side is relatively large and can pass over the protrusion 10. Regardless of the detection situation, when the operator releases the detection rods 1 on both sides, the detection rod 1 can be accurately restored to its horizontal original position under the action of the first spring 9 and the second spring 8 and complete the corresponding detection.
[0034] like Figure 1 As shown, in this embodiment, hinge seats 201 are provided on both sides of the detection seat body 2, and the front part of the detection rod 1 is rotatably installed in the hinge seat 201 on the corresponding side through the hinge shaft 4.
[0035] like Figure 7 As shown, in this embodiment, the front end of the detection seat body 2 is provided with a socket 203, the rear end of the through-end terminal column 5 is provided with an insert block, and the insert block is inserted into the socket 203. In addition, the insert block is provided with a fixing threaded hole, and one side of the front end of the detection seat body 2 is provided with a through hole, as shown in FIG. Figure 1As shown, when the insert block is fully inserted, the fixing bolt 501 passes through the through hole and is inserted into the fixing threaded hole on the insert block, thereby fixing the through-end column 5. When the through-end column 5 needs to be replaced, the operator screws the fixing bolt 501 outward to disengage it from the fixing threaded hole on the insert block, and then pulls out the through-end column 5 for replacement. The through-end column 5 is a well-known technology in the art.
[0036] like Figures 1 to 7 As shown, the rear end of the detection seat body 2 is provided with a handle 3 for the operator to hold. In this embodiment, Figure 7 As shown, the handle 3 is connected to the rear end of the detection base body 2 via a double-headed screw 301, so that the handle 3 and the detection base body 2 can be separated and replaced by rotating them in reverse.
[0037] The working principle of the utility model is:
[0038] With the continuous improvement of the structure of car audio basins, the port matching structure of many car audio basins has also changed. Figures 8-9 As shown, some car audio basins have protrusions 10 on both sides of the port for cooperating with other structures. Figures 10-11 As shown, some other car audio basin frames have notches 11 on both sides of the port for matching with other structures. The utility model can meet the detection needs of the above two situations, specifically:
[0039] Step 1: First, adjust the positions of the detection hooks 6 at the front ends of the two detection rods 1 according to the object to be detected (protrusion 10 or recess 11). When detecting the protrusion 10, the two detection hooks 6 are moved outward to increase the distance between them. When detecting the recess 11, the two detection hooks 6 are moved inward to reduce the distance between them.
[0040] Step 2: After the two detection hooks 6 are adjusted, the operator presses the detection rods 1 on both sides to make the two detection hooks 6 at the front end in an open state, and then inserts the through-end end column 5 into the port of the basin rack to be tested. If the through-end end column 5 can be inserted smoothly, the port inner hole inspection is qualified, otherwise it is unqualified.
[0041] In addition, Figure 7As shown, if it is to detect the notch 11, the operator can press the middle position of the detection rod 1 corresponding to the first spring 9. At this time, the opening angle of the two detection hooks 6 on the front side is relatively small. If it is to detect the protrusion 10, the detection personnel can press the rear end position of the detection rod 1 corresponding to the second spring 8. At this time, the opening angle of the two detection hooks 6 on the front side is relatively large and can pass over the protrusion 10. No matter what the detection situation is, when the operator releases the detection rods 1 on both sides, the detection rod 1 can be accurately restored to its horizontal original position under the action of the first spring 9 and the second spring 8 and complete subsequent detection.
[0042] Step 3: After the through-end column 5 is inserted, the operator releases the detection rods 1 on both sides. The detection rods 1 on both sides automatically return to their horizontal original positions under the action of springs. If the detection hook 6 at the front end of the detection rod 1 cannot fall completely, the detection fails.
[0043] Step 4: Finally, the operator pulls the detection seat body 2 backward horizontally. If the detection hook 6 can be engaged with the corresponding protrusion 10 or recess 11 and cannot be pulled out, the test is qualified. If the detection hook 6 and the corresponding protrusion 10 or recess 11 are disengaged and separated, the test is unqualified.
[0044] Compared with the prior art, the present invention does not need to be disassembled and replaced with a new detection hook 6 when in use. It only needs to screw the locking bolt 601 and adjust the position of the detection hook 6 according to the detection needs to meet different detection needs. Figure 2 As shown, the shape and size of the detection hook 6 need to be designed according to the conditions of the object to be detected, wherein a slope 602 is formed on the inner side of the detection hook 6, so that when the detection recess 11 is detected, after the detection rod 1 is released, the slope 602 can ensure that the detection hook 6 is smoothly transferred into the recess 11.
