Description

Technical Field

[0001] This utility model relates to the field of electronic product manufacturing tools, specifically to a highly stable foam height detection fixture. Background Technology

[0002] Conductive foam in electronic products is mainly used for electromagnetic signal shielding. Therefore, the thickness of the conductive foam is related to product performance. In the production process of electronic products, a quality inspection process is set up to test the products. When measuring the height of conductive foam, in order to ensure measurement accuracy, a fixture is used to clamp the workpiece, and then the measurement is performed using tools such as probes. The existing clamping fixture uses a high-precision stepper drive to drive the clamping jaws to move and clamp the workpiece. Because the clamping jaws are directly mounted on the drive device, the operation of the equipment depends entirely on the high-precision positioning of the drive device, resulting in poor equipment stability. Moreover, because it is a one-piece installation structure, the entire equipment needs to be replaced when it is damaged, which increases the cost of using this type of fixture. Therefore, the fixture structure needs to be improved and optimized. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a highly stable foam height detection fixture. It adopts a movable gripper structure and an elastically driven stepper structure to achieve stable operation of the gripper. Furthermore, in the event of equipment damage, only the damaged parts need to be replaced.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] It includes a base and further includes: a fixed clamping jaw, which is disposed on the base. An array of positioning screw holes is arranged on the upper surface of the base, and the fixed clamping jaw is fixedly disposed on the base by bolts engaging with the positioning screw holes; a movable clamping jaw, which is disposed to the side of the fixed clamping jaw and is disposed on the base; a movable seat, which is disposed on the side of the base opposite to the movable clamping jaw; and a connecting seat, which is integrally formed on the movable seat. A guide groove is provided on the base, and the connecting seat is slidably disposed in the guide groove. The movable clamping jaw is fixedly disposed on the connecting seat by bolts.

[0006] Preferably, the fixed gripper is integrally formed with a pressure-bearing seat, which is fixedly mounted on the base by bolts and positioning screw holes.

[0007] Preferably, a support seat is fixedly mounted on the movable seat by bolts. The support seat is movably embedded in the guide groove, and the upper surface of the support seat is flush with the upper surface of the base. The end of the support seat away from the movable seat extends below the fixed clamping claw.

[0008] Preferably, a bracket is provided below the base, a lead screw pair is fixedly provided on the support frame, and the lead screw pair is located below the movable seat. A transmission seat is screwed onto the lead screw end of the lead screw pair. Limit seats are symmetrically fixed on both sides of the lower side wall of the movable seat, and the transmission seat is located between the limit seats on both sides.

[0009] Preferably, a guide threaded rod is fixedly mounted on the limiting seat, and the transmission seat is movably sleeved on the guide threaded rod.

[0010] Preferably, a spring is sleeved on the guide threaded rod, with one end of the spring away from the fixed jaw abutting against the transmission seat and the other end of the spring abutting against the limiting seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This solution uses a movable seat and a connecting seat to set a movable jaw, and a fixed jaw is set on the base through a positioning screw hole. This allows the fixed jaw and the movable jaw to work together to clamp and fix the workpiece, so as to measure the foam height of the workpiece.

[0013] This solution utilizes the cooperation between the transmission seat and the limit seat, and the connection between the transmission seat and the limit seat is achieved through the guide thread rod and the spring. This enables the movable seat to move through the screw pair, which in turn drives the movable jaw to move, thus achieving the driving of the movable jaw. Attached Figure Description

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figure 1-5 As shown, the specific implementation adopts the following technical solution:

[0022] This specific embodiment includes a base 1, a fixed gripper 2, and a movable gripper 4. The base 1 has two parallel guide grooves 7 arranged front and rear. An array of positioning screw holes 3 are arranged on the base 1. The fixed gripper 2 spans across the guide grooves 7 and is fixedly mounted on the base 1 by bolts engaging with the positioning screw holes 3. A pressure-bearing seat 8 is integrally formed on the fixed gripper 2 and is fixedly mounted on the base 1 by bolts engaging with the positioning screw holes 3. A movable seat 5 is mounted below the base 1. A connecting seat 6 is fixedly mounted on the upper surface of the movable seat 5 and is movably embedded in the guide grooves 7. The movable gripper 4 spans across the guide grooves 7 and is connected to the connecting seat 6. The seats 6 are fixed together by bolts, and the movable gripper 4 is located to the right of the fixed gripper 2. A bracket 10 is mounted under the base 1, and a lead screw pair 11 is fixedly mounted on the bracket 10. A transmission seat 12 is threadedly fitted onto the lead screw end of the lead screw pair 11. Limit seats 13 are symmetrically fixed at both ends of the lower side wall of the movable seat 5. The transmission seat 12 is located between the limit seats 13 on the left and right sides. A guide threaded rod 14 is threadedly inserted and fixed onto the limit seat 13. The transmission seat 12 is movably mounted on the guide threaded rod 14. A spring 15 is mounted on the guide threaded rod 14. The left end of the spring 15 abuts against the left limit seat 13, and the right end of the spring 15 abuts against the transmission seat 12.

[0023] When using this device, the workpiece is clamped by the cooperation of the movable jaw 4 and the fixed jaw 2. The workpiece is placed on the base 1, and the movable jaw 4 is closed to clamp the workpiece in cooperation with the fixed jaw 2. Then, the height of the foam in the workpiece is measured. According to the size of a single batch of workpieces, the installation position of the fixed jaw 2 is selected, so that the span between the fixed jaw 2 and the movable jaw 4 is adjusted to match the workpiece model. The fixed jaw 2 is installed by the cooperation of bolts with the corresponding set of positioning screw holes 3. The movable seat 5 is placed against the lower surface of the base 1, and the connecting seat 6 is inserted into the guide groove 7. The movable jaw 4 is fixed to the connecting seat 6 by bolts, thus installing the movable jaw 4. The movable jaw 4 is moved by moving the movable seat 5, and the bracket 10 is erected. Below the base 1, the guide threaded rod 14 is inserted into the limiting seat 13, and the transmission seat 12 and spring 15 are simultaneously sleeved on the guide threaded rod 14 to connect the transmission seat 12 and the movable seat 5. The transmission seat 12 is moved by the lead screw pair 11, and the transmission seat 12 abuts against the limiting seat 13 through the spring 15, thereby moving the movable seat 5, which in turn moves the movable jaw 4. When the movable jaw 4 moves and clamps against the workpiece, as the lead screw pair 11 continues to move the transmission seat 12 in the clamping direction, the transmission seat 12 presses against the spring 15, and the elastic force of the spring 15 after contraction presses against the limiting seat 13, thereby abutting against the movable seat 5, so that the movable jaw 4 is pressed against the workpiece, realizing the clamping of the workpiece in conjunction with the fixed jaw 2.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. This device sets up multiple arrays of positioning screw holes 3 on the base 1, so that the fixed clamping jaw 2 can be installed in different positions on the base 1 when it is installed, thereby changing and adjusting the span between the fixed clamping jaw 2 and the moving clamping jaw 4 to meet the requirements of clamping workpieces of different sizes.

[0026] 2. This device uses a movable seat 5 and a connecting seat 6 to install a movable gripper 4, and a support seat 9 is installed on the movable seat 5 to block the guide groove 7. Thus, the movement of the movable seat 5 drives the movable gripper 4 to move, and cooperates with the fixed gripper 2 to clamp the workpiece, so as to facilitate the subsequent measurement of the foam height of the workpiece.

[0027] 3. This device connects the transmission seat 12 and the movable seat 5 through the cooperation of the guide thread rod 14 and the limiting seat 13, and is equipped with a spring 15. Thus, the transmission seat 12 is driven to move through the screw pair 11, thereby driving the movable seat 5 to move, which in turn drives the movable jaw 4. The workpiece is clamped through the cooperation of the movable jaw 4 and the fixed jaw 2.

[0028] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
