Description

Technical Field

[0001] This utility model relates to the field of cover plate fixing technology, and in particular to a cover plate inspection fixture clamping structure using a spring mechanism for clamping. Background Technology

[0002] Cover plate clamping fixture is a tooling used in the production and inspection of automotive cover plate parts to fix the cover plate in order to ensure the stability and reliability of the cover plate during the inspection process, thereby ensuring the accuracy of the inspection results.

[0003] However, existing cover plate clamps all adopt a fixed clamping structure. That is, when the existing clamps clamp the cover plate, they directly apply hard pressure to the cover plate through the clamping structure. In this way, it is difficult to control the clamping force during the clamping process, which can easily cause deformation of the cover plate surface, leading to deviations in subsequent test results and affecting the test effect. Furthermore, this hard-pressing method can easily cause the clamping structure to suddenly "over-press" during the unlocking process of the cover plate, which can also easily damage the cover plate surface. In addition, in order to ensure the clamping effect, existing clamps often require a large number of individual clamps, resulting in a high degree of structural complexity of the equipment and greater difficulty in operation, which affects its use.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a cover plate clamping device using a spring mechanism. This device clamps and fixes the cover plate by multiple clamping components on the clamp, which reduces the overall number of clamping structures. Furthermore, through the structural design of the clamp, the pressure applied by the clamping head to the cover plate during clamping and fixing is formed as a "soft" fixing pressure. Therefore, it can clamp and fix the cover plate while avoiding damage to the cover plate due to excessive pressure, thus ensuring the accuracy of the inspection.

[0006] To achieve the above objectives, this utility model provides a cover plate inspection clamping structure using a spring mechanism, comprising a base plate for clamping and fixing the cover plate to be inspected, and a base plate, wherein a plurality of base brackets for supporting the bottom of the cover plate are installed on the upper part of the base plate, and an annular sleeve is installed around the base brackets on the upper surface of the base plate.

[0007] A second support is installed above the base plate, located outside the base bracket. A clamp is installed on the top of the second support, and multiple clamping components are installed on the clamp. The clamp can be rotated to a first position and a second position. The first position is where the main body of the clamp is above the base bracket, and the clamping components on the clamp can clamp and fix the cover plate. The second position is a preparatory position where the main body of the clamp is flipped upward to the outside of the second support. A locking mechanism is also installed on the top of the second support to lock the clamp in the first position.

[0008] In one embodiment of this utility model, the clamping clamp is provided with a mounting through hole for installing a clamping component. The clamping component includes a rod body, which is inserted into the mounting through hole. A pressure head is installed at the front end of the rod body, and an end plate is installed at the rear end. A baffle is also provided in the middle of the rod body. A spring is provided between the baffle and the clamping clamp, and the spring is sleeved on the rod body. Based on this, when the clamping clamp is in the first position, the pressure head at the front end of the clamping component presses against the upper surface of the cover plate. When the pressure head presses against the upper surface of the cover plate, the rod body is forced to move backward. At this time, the spring can provide a pushing force to the rod body. This makes the pressure applied by the pressure head to the cover plate form a "soft" fixing pressure. Therefore, the cover plate can be clamped and fixed, and damage to the cover plate caused by excessive pressure can be avoided.

[0009] In one embodiment of this utility model, the clamp includes a central rod, side rods, and a crossbar. The central rod is located in the middle of the crossbar, and two side rods are respectively located at both ends of the crossbar. The side rods are parallel to the central rod, and the central rod is perpendicular to the crossbar, forming a "mountain" shaped structure. A clamping component is installed at the front end of both the central rod and the side rods. Based on this, one clamp can provide three clamping points to the cover plate, and these three points correspond to the positions above the base bracket. Therefore, the clamping effect of each clamp in this device is better, reducing the complexity of the clamping structure and simplifying and facilitating the clamping process.

[0010] In one embodiment of this utility model, a T-shaped piece is provided on the top of the second support, and a connecting piece is rotatably installed above the vertical end of the T-shaped piece. A tail rod is also provided in the middle of the crossbar in a direction perpendicular to the crossbar. The tail rod is connected to the front end of the connecting piece. Based on this, the clamp can be flipped directly up and down to achieve flipping between the first position and the second position.

[0011] In one embodiment of this utility model, the locking mechanism includes a saddle, a top buckle, and a handle. The saddle has an inverted "V" shape, and the handle is located on top of the saddle, forming an inverted "Y" shape with the saddle. The saddle is rotatably mounted above the T-shaped piece and covers the connector inside. The top buckle is installed on the inner side of the saddle, and the upper surface of the connector has a notch at the corresponding position of the top buckle. Based on this, when the clamp needs to be locked in the first position, the handle is used to rotate the saddle, causing the top buckle on the inner side of the saddle to engage with the notch above the connector. At this time, due to the reaction force of the spring on the clamp, the clamp has an upward tendency, so the top buckle can keep engaging with the notch, fixing the clamp in the first position. When it is necessary to unlock the clamp, simply press the clamp to disengage the top buckle from the notch, and then flip the handle outward to unlock the clamp. The overall operation is convenient and quick.

[0012] In one embodiment of this utility model, multiple sets of clamps are provided, and the multiple sets of clamps are distributed in a crisscross and staggered manner on both sides of the annular sleeve.

[0013] In one embodiment of the present invention, the upper surface of the base plate is further provided with a plurality of first supports, which are respectively arranged around the annular sleeve. Each first support is provided with a lateral support plate at its top, and the front end of the lateral support plate presses against the edge of the annular sleeve, thereby strengthening and stabilizing the lateral support plate.

[0014] Compared with the prior art, the cover plate clamping clamp structure of the present invention uses a spring mechanism to clamp and fix the cover plate by multiple clamping components on the clamp, which can reduce the overall number of clamping structures. Furthermore, through the structural design of the clamp, the reduced number of clamping components will not affect the fixing stability of the cover plate. In addition, by setting a locking mechanism on the top of the second support, the clamp can be locked in the first position, making the operation convenient and simple.

[0015] This device employs an "elastic clamping" clamping component, which creates a "soft" fixing pressure when clamping and fixing the cover plate. Therefore, it can not only clamp and fix the cover plate, but also avoid damage to the cover plate caused by excessive pressure, ensuring the accuracy of the detection. Furthermore, the design of the locking mechanism makes it convenient and quick to lock and unlock the clamping component. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 The specific embodiments of this utility model will be described in detail, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0022] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0023] like Figure 1 As shown, a cover plate inspection clamping clamp structure using a spring mechanism according to a preferred embodiment of the present utility model includes a cover plate 3a to be inspected for clamping and fixing. It includes a base plate 1, and a plurality of base brackets 6 for supporting the bottom of the cover plate 3a are installed on the top of the base plate 1. An annular sleeve 3 is installed around the base brackets 6 on the upper surface of the base plate 1.

[0024] A second support 4 is installed above the base plate 1 on the outside of the base bracket 6. A clamp 5 is installed on the top of the second support 4. Multiple clamping parts 9 are installed on the clamp 5. The clamp 5 can be rotated to a first position and a second position. The first position is when the main body of the clamp 5 is above the base bracket 6, and the clamping parts 9 on the clamp 5 can clamp and fix the cover plate 3a. The second position is when the main body of the clamp 5 is flipped upward to the outside of the second support 4. A locking mechanism 7 for locking the clamp 5 in the first position is also installed on the top of the second support 4.

[0025] Working principle: First, the clamp 5 is in the second position, at which time the top of the base bracket 6 is exposed. When it is necessary to clamp and fix the cover plate 3a to be tested, first place the cover plate 3a above the base bracket 6 on the inner side of the annular sleeve 3. After completion, by rotating the clamp 5, the clamp 5 is rotated from the second position to the first position. At this time, the clamping part 9 on the clamp 5 can directly clamp the top of the cover plate 3a, which is convenient and quick to operate.

[0026] In summary, the device uses multiple clamping components 9 on the clamp 5 to clamp and fix the cover plate 3a, which reduces the overall number of clamping structures. Furthermore, the structural design of the clamp 5 ensures that the reduced number of clamping components does not affect the stability of the cover plate 3a. Additionally, by setting a locking mechanism 7 on the top of the second support 4, the clamp 5 can be locked in the first position, making operation convenient and simple.

[0027] Specifically, such as Figure 3 - Figure 4 As shown, in order to achieve the clamping and fixing of the cover plate 3a, in this embodiment, the clamping clamp 5 is provided with a mounting through hole 53 for installing the clamping component 9. The clamping component 9 includes a rod 93, which is inserted into the mounting through hole 53. A pressure head 94 is installed at the front end of the rod 93, and an end plate 90 is installed at the rear end. A baffle 92 is also provided in the middle of the rod 93. A spring 91 is provided between the baffle 92 and the clamping clamp 5. The spring 91 is sleeved on the rod 93. Based on this, when When the clamp 5 is in the first position, the pressure head 94 at the front end of the clamping component 9 presses against the upper surface of the cover plate 3a. When the pressure head 94 presses against the upper surface of the cover plate 3a, the rod 93 is forced to move backward. At this time, the spring 91 can provide a thrust to the rod 93. This makes the pressure applied by the pressure head 94 to the cover plate 3a a "soft" fixing pressure. Therefore, the cover plate 3a can be clamped and fixed, and the excessive pressure can be avoided to prevent damage to the cover plate 3a.

[0028] Specifically, such as Figure 1 - Figure 4As shown, in order to achieve multi-point fixation, in this embodiment, the clamp 5 includes a central rod 51, side rods 52, and a cross rod 54. The central rod 51 is located in the middle of the cross rod 54, and there are two side rods 52, which are respectively located at both ends of the cross rod 54. The side rods 52 are parallel to the central rod 51, and the central rod 51 is perpendicular to the cross rod 54, so that the central rod 51, side rods 52, and cross rod 54 form a "mountain" shaped structure. The front ends of the central rod 51 and the side rods 52 are each equipped with a clamping component 9. Based on this, one clamp 5 can provide three clamping points to the cover plate 3a, and these three points are respectively located above the bottom bracket 6. Therefore, the clamping effect of each clamp 5 in this device is better, the complexity of the clamping structure is reduced, and the clamping structure is simplified and made more convenient.

[0029] Specifically, such as Figure 3 - Figure 4 As shown, in order to enable the clamp 5 to flip between the first position and the second position, in this embodiment, a T-shaped piece 40 is provided on the top of the second support 4, and a connector 8 is rotatably installed above the vertical end of the T-shaped piece 40. A tail rod 50 is also provided in the middle of the crossbar 54 in a direction perpendicular to the crossbar 54. The tail rod 50 is connected to the front end of the connector 8. Based on this, the clamp 5 can directly flip up and down to achieve flipping between the first position and the second position.

[0030] Specifically, such as Figure 3 - Figure 4 As shown, in order to lock the clamp 5 in the first position, in this embodiment, the locking mechanism 7 includes a clamp 70, a top latch 71, and a handle 72. The clamp 70 has an inverted "V" shape, and the handle 72 is located on top of the clamp 70, forming an inverted "Y" shape with the clamp 70. The clamp 70 is rotatably mounted above the T-shaped member 40 and covers the connector 8 inside. The top latch 71 is installed on the inner side of the clamp 70, and the upper surface of the connector 8 has a notch at the corresponding position of the top latch 71. Based on this, when... When the clamp 5 needs to be locked in the first position, rotate the cam 70 by the handle 72 so that the top buckle 71 on the inner side of the cam 70 engages in the recess above the connector 8. At this time, due to the reaction force of the spring 91 on the clamp 5, the whole clamp has an upward tendency, so the top buckle 71 can keep engaging the recess and fix the clamp 5 in the first position. When it is necessary to unlock the clamp 5, simply press the clamp 5 so that the top buckle 71 can disengage from the recess, and then flip the handle 72 outward to unlock the clamp 5. The whole operation is convenient and quick.

[0031] Specifically, such as Figure 1 - Figure 2 As shown, in order to improve the fixing effect on the cover plate 3a, in this embodiment, multiple sets of clamps 5 are provided, and the multiple sets of clamps 5 are distributed in a crisscross and staggered manner on both sides of the annular sleeve 3.

[0032] Specifically, such as Figure 1 - Figure 2 As shown, in order to make the annular sleeve 3 more secure and stable, in this embodiment, the upper surface of the base plate 1 is also provided with a plurality of first supports 2, which are respectively arranged around the annular sleeve 3. Each first support 2 is provided with a lateral support plate 20 at its top. The front end of the lateral support plate 20 presses against the edge of the annular sleeve 3, thereby strengthening and stabilizing the lateral support plate 20.

[0033] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
