Description

Technical Field

[0001] This utility model relates to the field of inspection equipment technology, and in particular to a device for detecting hole positions in sheet metal parts. Background Technology

[0002] Sheet metal parts are products manufactured using sheet metal processing techniques. During the production process, existing sheet metal parts need to have their punching holes inspected to prevent issues such as missed punching holes and to improve product quality.

[0003] The current method for inspecting sheet metal parts generally involves manual inspection of the pin holes using inspection pins. This method, which uses inspection fixtures, requires manual clamping of the sheet metal part by hand, followed by inspection of each hole using inspection pins. This is inefficient and requires inspecting multiple holes sequentially, which can easily lead to missed inspections and affect the overall inspection results. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a hole position detection device for sheet metal parts to solve the problem of low detection efficiency.

[0005] To achieve the above objectives, this utility model provides a device for detecting hole positions in sheet metal parts, including a detection table, a support on the detection table, a drive cylinder mounted on the support, a lifting support mounted on the output end of the drive cylinder, an upper detection mechanism located in the middle of the lower side of the lifting support, and side detection mechanisms mounted at both ends of the detection table. The upper detection mechanism is used to detect the upper hole positions of the workpiece, and the side detection mechanisms are used to detect the side hole positions of the workpiece. Pushing mechanisms are provided on both sides of the lifting support to drive the side detection mechanisms for detection. Positioning blocks are provided on both sides of the detection table to position and place the workpiece.

[0006] A further improvement is that the upper detection mechanism includes an upper base, which is installed on the lower side of the lifting bracket. An upper mounting hole is provided on the upper base, and an upper detection pin is slidably installed in the upper mounting hole.

[0007] A further improvement is that the side detection mechanism includes a side base, which is slidably mounted on the detection platform. A side mounting hole is provided on the side base, and a side detection pin is slidably mounted in the side mounting hole.

[0008] A further improvement is that a return spring is fitted on both the upper detection pin and the side detection pin.

[0009] A further improvement is that the detection end of the upper detection pin and the side detection pin is tapered, and the other end of the upper detection pin and the side detection pin is provided with scale lines.

[0010] A further improvement is that a movable groove is provided on the testing platform, and the lower end of the side base is slidably set in the movable groove. A telescopic spring is connected between the side wall of the movable groove and the lower end of the side base.

[0011] A further improvement is that a sliding groove is provided on the side of the side base, a clamping block is slidably disposed in the sliding groove, and a clamping spring is connected between the clamping block and the sliding groove.

[0012] A further improvement is that the pushing mechanism includes a pushing block, which is fixedly mounted on the end of the lifting bracket, and both the pushing block and the side base are inclined sides.

[0013] The beneficial effects of this utility model are as follows: By setting a driving cylinder to drive the lifting bracket to move, the upper base moves the upper detection pin to detect the holes on the upper surface of the workpiece. The lifting bracket drives the pushing block to move down, and the pushing block moves the side base, so that the side base clamps the workpiece from both sides and drives the side detection pin to detect the holes on the side of the workpiece. By using the upper detection pin and the side detection pin to detect the holes on multiple sides of the workpiece at the same time, the detection efficiency is greatly improved. In addition, the end of the detection pin is tapered, which can achieve different insertion depths according to the holes. Different insertion depths result in different scale lines protruding from the other end. The position of the scale line is used to detect the position and diameter of the hole, which greatly improves the detection effect. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this embodiment provides a device for detecting hole positions in sheet metal parts, including a detection table 1. Positioning blocks 5 are provided on both sides of the detection table 1, and the workpiece is positioned on the detection table 1 by the positioning blocks 5. A bracket 2 is provided on the detection table 1, and a drive cylinder 3 is mounted on the bracket 2. A lifting bracket 4 is mounted on the output end of the drive cylinder 3. The drive cylinder 3 drives the lifting bracket 4 to move up and down. An upper detection mechanism is provided in the middle of the lower side of the lifting bracket 4. The upper detection mechanism is moved down by the lifting bracket 4 to detect the upper hole positions of the workpiece placed on the detection table 1.

[0020] The lifting bracket 4 is equipped with a pushing mechanism on both sides, and the inspection table 1 is equipped with a side inspection mechanism at both ends. The lifting mechanism drives the pushing mechanism to move down, and the pushing mechanism moves down and contacts the side inspection mechanism. The pushing mechanism pushes the side inspection mechanism to move and clamps and fixes the workpiece from both sides and inspects the side holes of the workpiece.

[0021] The upper detection mechanism includes an upper base 6, which is installed on the lower side of the lifting bracket 4. An upper mounting hole 7 is provided on the upper base 6, and an upper detection pin 8 is slidably installed in the upper mounting hole 7.

[0022] The side inspection mechanism includes a side base 9, which is slidably mounted on the inspection table 1. A side mounting hole 10 is provided on the side base 9, and a side inspection pin 11 is slidably installed in the side mounting hole 10.

[0023] The pushing mechanism includes a pushing block 18, which is fixedly installed at the end of the lifting bracket 4. Both the pushing block 18 and the side base 9 have inclined sides on opposite sides. The inclined sides of the pushing block 18 are adapted to the inclined sides of the side base 9. As the lifting bracket 4 moves down, the pushing block 18 makes contact with the inclined surface of the side base 9. As the pushing block 18 moves down, it pushes the side base 9 to move towards the center and fit against the workpiece, thus clamping the workpiece.

[0024] As shown in the figure, a movable groove 13 is provided on the testing table 1, and the lower end of the side base 9 is slidably disposed in the movable groove 13. The side base 9 moves in the movable groove 13 by being pushed by the push block 18. A telescopic spring 14 is connected between the side wall of the movable groove 13 and the lower end of the side base 9. After the push block 18 rises and resets, the push block 18 releases the pushing force on the side base 9, and the side base 9 slides back to its original position by the action of the telescopic spring 14.

[0025] Both the upper detection pin 8 and the side detection pin 11 are fitted with return springs 12. The two ends of the return spring 12 on the upper detection pin 8 are connected to the inner wall of the upper detection pin 8 and the upper mounting hole 7, respectively. The two ends of the return spring 12 on the side detection pin 11 are connected to the inner wall of the side detection pin 11 and the side mounting hole 10, respectively. One detection end of the upper detection pin 8 and the side detection pin 11 is tapered, with the diameter of the corresponding hole marked on the tapered end. The other end of the upper detection pin 8 and the side detection pin 11 is provided with scale lines. As the upper base 6 and the side base 9 move, the upper detection pin 8 and the side detection pin 11 are inserted into the holes on the upper and side sides of the workpiece, respectively. The ends of the upper detection pin 8 and the side detection pin 11 are inserted to the corresponding depth according to the diameter of the hole to be detected. Through the pressure of the workpiece, the other ends of the upper detection pin 8 and the side detection pin 11 protrude from the upper mounting hole 7 and the side mounting hole 10. By observing the length of the protrusion, the position of the hole and whether the hole diameter meets the quality standard can be quickly determined, thus achieving rapid detection.

[0026] like Figure 3 As shown, a sliding groove 15 is provided on the side of the side base 9, and a clamping block 16 is slidably disposed in the sliding groove 15. A clamping spring 17 is connected between the clamping block 16 and the sliding groove 15. After the workpiece is positioned by the positioning block 5, the clamping block 16 clamps the workpiece in the middle from both sides to stabilize the workpiece. As the side base 9 slides towards the middle, the clamping block 16 gradually slides and retracts into the sliding groove 15 until the end face of the clamping block 16 is on the same plane as the surface of the side base 9.

[0027] During inspection, the workpiece is placed on the inspection table 1, the positioning block 5 limits the placement of the workpiece, and the clamping blocks 16 on both sides initially clamp and position the workpiece. The drive cylinder 3 drives the lifting bracket 4 to move downward, and the lifting bracket 4 drives the upper base 6 and the push block 18 to move downward. The upper base 6 drives the upper detection pin 8 to inspect the hole on the upper surface of the workpiece. The push block 18 contacts the side base 9 and pushes the side base 9 to move towards the workpiece. The side base 9 clamps and fixes the workpiece from both sides, and at the same time drives the side detection pin 11 to inspect the hole on the side of the workpiece. The upper detection pin 8 and the side detection pin 11 are inserted into the corresponding hole. The insertion depth varies according to the diameter of the hole. The ends of the upper detection pin 8 and the side detection pin 11 are engaged with the side of the hole. The reaction force causes the upper detection pin 8 and the side detection pin 11 to retract into the upper mounting hole 7 and the side mounting hole 10. The other end of the upper detection pin 8 and the side detection pin 11 protrudes. The position and diameter of the hole are observed by observing the scale line to see if they meet the requirements, making the inspection results easy to observe directly.
