Description

Technical Field

[0001] This utility model relates to the field of fixture life inspection technology, and in particular to an opening and closing handle inspection device. Background Technology

[0002] In the fields of electronic component assembly and precision parts processing, pressure-holding fixtures with handles are widely used. The handle and the base plate are rotatably connected by a pivot, and there are rolling steel balls at the contact point between the handle and the cover plate. The opening and closing of the handle and the pressure-holding function are realized by springs.

[0003] Currently, in long-term use, pressure-holding fixtures with handles experience frequent opening and closing of the handles, which can lead to fatigue failure of the springs. The rotation of the shaft can cause wear on the base plate, and the rolling of the steel balls can exacerbate wear on the cover plate. These problems directly affect the pressure-holding accuracy and service life of the fixture.

[0004] Therefore, there is an urgent need for an opening and closing handle inspection device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an opening and closing handle inspection device to inspect the service life of the pressure holding fixture, inspect spring fatigue, base plate wear, and cover plate wear, and ensure the pressure holding accuracy and service life inspection accuracy of the pressure holding fixture.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An opening / closing handle inspection device is used to inspect the service life of a pressure-holding fixture. The pressure-holding fixture includes a fixture body and a first handle and a second handle rotatably disposed on both sides of the fixture body. The opening / closing handle inspection device includes:

[0008] The base and the support are spaced apart and extend parallel to each other along the first direction;

[0009] A support member, through which the base and the support seat are connected;

[0010] A locating pin is provided on the support base and is configured to fix the relative position of the fixture body and the support base;

[0011] The system includes a bidirectional cylinder, a first limiting component, and a second limiting component. The bidirectional cylinder is mounted on the base, and the first and second limiting components are respectively mounted on the two output ends of the bidirectional cylinder. The first limiting component is configured to limit and guide the first handle, and the second limiting component is configured to limit and guide the second handle. The bidirectional cylinder can simultaneously drive the first and second limiting components to reciprocate in opposite or opposite directions along the first direction, thereby causing the first and second handles to reciprocate and rotate relative to the fixture body for opening and closing.

[0012] As an optional solution for the opening and closing handle inspection device, the first limiting component includes a first connecting member, a first constraint member, and a first stop member. The first constraint member and the first stop member are sequentially spaced apart along the positive direction of the first direction on the first connecting member. The first handle can be inserted into the first receiving area clamped by the first constraint member and the first stop member.

[0013] The second limiting component includes a second connector, a second stop, and a second constraint. The second connector is provided with the second stop and the second constraint sequentially spaced apart along the positive direction of the first direction. The second handle can be inserted into the second receiving area clamped by the second stop and the second constraint.

[0014] The two output ends of the bidirectional cylinder are respectively connected to the first connector and the second connector. The bidirectional cylinder can simultaneously drive the first connector and the second connector to move back and forth or towards each other along the first direction, so as to drive the first handle and the second handle to rotate back and forth relative to the main body of the fixture to open and close.

[0015] As an optional solution for the opening and closing handle inspection device, the first receiving area reserves a rotation gap at a corresponding position on the first handle so that the first handle can rotate relative to the fixture body within the first receiving area;

[0016] The second receiving area provides a rotation gap for the corresponding position on the second handle, so that the second handle can rotate relative to the fixture body within the second receiving area.

[0017] As an optional solution for the handle opening and closing inspection device, the first limiting component further includes a first positioning fastener. The first stop has a first oblong hole extending along the first direction. The first positioning fastener can pass through the first oblong hole and connect with the first connector. When the first stop moves relative to the first connector, the first positioning fastener can slide within the first oblong hole. The first positioning fastener is configured to lock the relative position between the first stop and the first connector so that the size of the first receiving area is adjustable.

[0018] The second limiting component also includes a second positioning fastener. The second stop has a second oblong hole extending along the first direction. The second positioning fastener can pass through the second oblong hole and connect with the second connector. When the second stop moves relative to the second connector, the second positioning fastener can slide within the second oblong hole. The second positioning fastener is configured to lock the relative position between the second stop and the second connector so that the size of the second receiving area is adjustable.

[0019] As an optional solution for the handle inspection device, the fixture body is provided with positioning holes that correspond one-to-one with the positioning pins. The positioning pins can extend into the corresponding positioning holes and transition fit to fix the relative position of the fixture body and the support base.

[0020] As an alternative solution for the handle opening and closing inspection device, the height of the support is adjustable so that the distance between the base and the support seat is adjustable.

[0021] As an optional solution for the opening and closing handle inspection device, the support includes an adjusting fastener, a first column and a second column that are nested together. The first column and the second column are each provided with adjusting holes spaced apart along their height direction. The adjusting fastener can pass through the adjusting holes at corresponding positions to fix the relative positions of the first column and the second column.

[0022] As an optional solution for the handle opening and closing inspection device, the handle opening and closing inspection device further includes a counting sensor and a controller. The counting sensor is configured to detect the first number of reciprocating movements of the first limit component and the second limit component. The counting sensor is communicatively connected to the controller, which is configured to receive the first number of times and convert the first number of times into the second number of times the first handle and the second handle are opened and closed.

[0023] As an alternative solution for the handle opening and closing inspection device, the handle opening and closing inspection device also includes a display screen, which is communicatively connected to the controller and configured to display the second data information in real time.

[0024] As an optional solution for the handle opening and closing inspection device, the base is equipped with an anti-slip pad on the bottom.

[0025] Beneficial effects:

[0026] This invention provides an opening and closing handle inspection device. During operation, the base and support are kept parallel and spaced apart by a support member. A positioning pin on the support fixes the relative position of the fixture body and the support, ensuring the stability of the pressure-holding fixture. A first limiting component guides the first handle, and a second limiting component guides the second handle. Activating a bidirectional cylinder on the base causes the two outputs of the cylinder to drive the first and second limiting components to move synchronously in opposite or opposite directions along a first direction, thereby causing the first and second handles to rotate reciprocally relative to the fixture body for opening and closing. This opening and closing handle inspection device simulates actual usage scenarios to inspect the service life of the pressure-holding fixture. It can efficiently inspect spring fatigue, base plate wear, and cover plate wear, ensuring the accuracy of pressure holding precision and service life inspection of the pressure-holding fixture.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] This embodiment discloses an opening and closing handle inspection device, such as... Figures 1-4 As shown, the opening and closing handle inspection device is used to inspect the service life of the pressure holding fixture 100. The pressure holding fixture 100 includes a fixture body 110 and a first handle 101 and a second handle 102 rotatably disposed on both sides of the fixture body 110. The fixture body 110 includes a base plate 111 and a cover plate 112. The first handle 101 and the second handle 102 are rotatably connected to both sides of the base plate 111 via pivots (not shown). Rollable steel balls (not shown) are provided at the contact points between the first handle 101 and the second handle 102 and the cover plate 112. The opening, closing and pressure holding functions of the first handle 101 and the second handle 102 are realized by springs.

[0046] Currently, during long-term use of the pressure holding fixture 100, the first handle 101 and the second handle 102 open and close frequently, the springs are prone to fatigue failure, the rotation of the shaft will cause wear on the base plate 111, and the rolling of the steel balls will also aggravate the wear of the cover plate 112, directly affecting the pressure holding accuracy and service life of the pressure holding fixture 100.

[0047] like Figures 1-4 As shown, the handle inspection device of this embodiment includes a base 1, a support 2, a support member 3, a positioning pin 4, a bidirectional cylinder 5, a first limiting component 6, and a second limiting component 7. The base 1 and the support 2 are spaced apart and extend parallel to each other along a first direction. The base 1 and the support 2 are connected by the support member 3. The positioning pin 4 is disposed on the support 2 and is used to fix the relative position of the fixture body 110 and the support 2. The bidirectional cylinder 5 is disposed on the base 1. The first limiting component 6 and the second limiting component 7 are respectively disposed on the two output ends of the bidirectional cylinder 5. The first limiting component 6 is used to limit and guide the first handle 101, and the second limiting component 7 is used to limit and guide the second handle 102. The bidirectional cylinder 5 can simultaneously drive the first limiting component 6 and the second limiting component 7 to reciprocate in opposite directions or towards each other along the first direction, so as to drive the first handle 101 and the second handle 102 to reciprocate and rotate relative to the fixture body 110 to open and close.

[0048] During operation, the base 1 and support 2 are kept parallel to each other by the support member 3. The relative position of the fixture body 110 and the support 2 is fixed by the positioning pin 4 on the support 2, ensuring the stability of the pressure holding fixture 100. The first limiting component 6 limits and guides the first handle 101, and the second limiting component 7 limits and guides the second handle 102. When the bidirectional cylinder 5 on the base 1 is activated, the two output ends of the bidirectional cylinder 5 drive the first limiting component 6 and the second limiting component 7 to move synchronously back and forth or towards each other in the first direction, thereby causing the first handle 101 and the second handle 102 to rotate back and forth relative to the fixture body 110 to open and close. This opening and closing handle inspection device simulates actual use scenarios to inspect the service life of the pressure holding fixture 100. It can efficiently inspect spring fatigue, wear of the base plate 111, and wear of the cover plate 112, ensuring the pressure holding accuracy and service life inspection accuracy of the pressure holding fixture 100.

[0049] like Figures 1-4As shown, the first limiting component 6 includes a first connector 61, a first constraint member 62, and a first stop member 63. The first constraint member 62 and the first stop member 63 are sequentially spaced along the positive direction of the first direction on the first connector 61. The first handle 101 can be inserted into the first receiving area clamped by the first constraint member 62 and the first stop member 63. The second limiting component 7 includes a second connector 71, a second stop member 73, and a second constraint member 72. The second stop member 73 and the second constraint member 72 are sequentially spaced along the positive direction of the first direction on the second connector 71. The second handle 102 can be inserted into the second receiving area clamped by the second stop member 73 and the second constraint member 72. The two output ends of the bidirectional cylinder 5 are respectively connected to the first connector 61 and the second connector 71. The bidirectional cylinder 5 can simultaneously drive the first connector 61 and the second connector 71 to reciprocate in opposite directions or towards each other along the first direction, so as to drive the first handle 101 and the second handle 102 to reciprocate and rotate relative to the fixture body 110 for opening and closing. By precisely constraining the movement trajectory of the handle and simulating actual usage scenarios, it can efficiently test spring fatigue, base plate 111 wear, and cover plate 112 wear, ensuring the inspection accuracy and efficiency of the pressure holding fixture 100.

[0050] Specifically, such as Figures 5-6 As shown, when the handle inspection device is working, the first handle 101 of the pressure-holding fixture 100 is first inserted into the first receiving area clamped between the first constraint member 62 and the first stop member 63 in the first limiting assembly 6, and the second handle 102 is inserted into the second receiving area clamped between the second stop member 73 and the second constraint member 72 in the second limiting assembly 7. Then, the fixture body 110 is fixed by the positioning pin 4. Figures 7-8 As shown, when the bidirectional cylinder 5 is activated, the two output ends of the bidirectional cylinder 5 drive the first connecting piece 61 and the second connecting piece 71 to move back and forth or towards each other along the first direction, thereby driving the first handle 101 and the second handle 102 to rotate back and forth relative to the fixture body 110 to open and close.

[0051] like Figures 7-8As shown, the first receiving area provides a rotational clearance for the corresponding position on the first handle 101, allowing the first handle 101 to rotate relative to the fixture body 110 within the first receiving area under the action of the first limiting component 6. The second receiving area provides a rotational clearance for the corresponding position on the second handle 102, allowing the second handle 102 to rotate relative to the fixture body 110 within the second receiving area under the action of the second limiting component 7. By providing a rotational clearance for the first handle 101 in the first receiving area, it is ensured that the first handle 101 rotates smoothly relative to the fixture body 110 under the action of the first limiting component 6, achieving precise limiting in conjunction with the first constraint component 62 and the first stop component 63. Similarly, by providing a rotational clearance for the second handle 102 in the second receiving area, the second handle 102 rotates smoothly relative to the fixture body 110 under the action of the second limiting component 7, achieving precise limiting in conjunction with the second constraint component 72 and the second stop component 73. This ensures the stability of the handle opening and closing simulation of the pressure holding fixture 100 and improves the accuracy of service life inspection.

[0052] Specifically, such as Figures 5-6 As shown, during the process of pushing the first handle 101 and the second handle 102 to open, the first handle 101 is placed in the first receiving area of ​​the first limiting component 6. The first limiting component 6 and the second limiting component 7 move in opposite directions, that is, the first limiting component 6 moves in the opposite direction along the first direction, and the second limiting component 7 moves in the forward direction along the first direction. The first stop 63 pushes the first handle 101 to rotate and open, and the second stop 73 pushes the second handle 102 to rotate and open. The first constraint 62 prevents the first handle 101 from coming out, and the second constraint 72 prevents the second handle 102 from coming out.

[0053] like Figures 7-8 As shown, during the process of pushing the first handle 101 and the second handle 102 to close, the first limiting component 6 and the second limiting component 7 move towards each other, that is, the first limiting component 6 moves in the forward direction of the first direction, and the second limiting component 7 moves in the reverse direction of the first direction. The first constraint member 62 pushes the first handle 101 to rotate and reset to close, and the second constraint member 72 pushes the second handle 102 to rotate and reset to close. The first stop member 63 restricts the position of the first handle 101 to avoid excessive rotation, and the second stop member 73 restricts the position of the second handle 102 to avoid excessive rotation.

[0054] like Figure 3As shown, the first limiting component 6 also includes a first positioning fastener. The first stop 63 is provided with a first oblong hole 630 extending in a first direction. The first positioning fastener can pass through the first oblong hole 630 and connect with the first connecting member 61. When the first stop 63 moves relative to the first connecting member 61, the first positioning fastener can slide within the first oblong hole 630. The first positioning fastener is used to lock the relative position between the first stop 63 and the first connecting member 61, so that the size of the first receiving area is adjustable. The first stop 63 of the first limiting component 6 cooperates with the first positioning fastener through the first oblong hole 630, and can adjust and lock its position relative to the first connecting member 61, so that the size of the first receiving area is adjustable. This can adapt to the inspection requirements of different specifications of the first handle 101 without replacing the entire first limiting component 6, improving the adaptability of the opening and closing handle inspection device to the pressure holding fixture 100, reducing inspection costs, and improving inspection efficiency.

[0055] like Figure 3 As shown, the second limiting component 7 also includes a second positioning fastener. The second stop 73 is provided with a second oblong hole 730 extending along the first direction. The second positioning fastener can pass through the second oblong hole 730 and connect with the second connecting member 71. When the second stop 73 moves relative to the second connecting member 71, the second positioning fastener can slide within the second oblong hole 730. The second positioning fastener is used to lock the relative position between the second stop 73 and the second connecting member 71, so that the size of the second receiving area is adjustable. The second stop 73 of the second limiting component 7 cooperates with the second positioning fastener through the second oblong hole 730, and can adjust and lock its position relative to the second connecting member 71, so that the size of the second receiving area is adjustable. This can adapt to the inspection requirements of different specifications of the second handle 102 without replacing the entire second limiting component 7, improving the adaptability of the opening and closing handle inspection device to the pressure holding fixture 100, reducing inspection costs, and improving inspection efficiency.

[0056] In this embodiment, the first stop member 63 is provided with two first oblong holes 630, corresponding to two first positioning fasteners; the second stop member 73 is provided with two second oblong holes 730, corresponding to two second positioning fasteners. Here, the number of first oblong holes 630, the number of first positioning fasteners, the number of second oblong holes 730, and the number of second positioning fasteners are not specifically limited.

[0057] In this embodiment, the first positioning fastener is a bolt, which can reliably pass through the first oblong hole 630. After locking, it securely fixes the relative position of the first stop 63 and the first connecting member 61, ensuring that the size of the first receiving area is determined and improving the compatibility and inspection reliability with the first handle 101. The second positioning fastener is a bolt, which can reliably pass through the second oblong hole 730. After locking, it securely fixes the relative position of the second stop 73 and the second connecting member 71, ensuring that the size of the second receiving area is determined and improving the compatibility and inspection reliability with the second handle 102.

[0058] like Figures 1-2 , Figures 4-5 As shown, the fixture body 110 is provided with positioning holes 113 corresponding to the positioning pins 4. The positioning pins 4 can extend into the corresponding positioning holes 113 and transition fit to fix the relative position of the fixture body 110 and the support base 2. This quickly achieves precise alignment between the fixture body 110 and the support base 2, stably fixes their relative positions, prevents the pressure holding fixture 100 from shifting during the inspection process, and ensures precise matching and movement of the first handle 101 and the first limit component 6, and the second handle 102 and the second limit component 7. This provides a stable foundation for inspecting the service life of the pressure holding fixture 100 and improves the accuracy of the inspection.

[0059] In this embodiment, there are two positioning pins 4, which are spaced apart on both sides of the support base 2. Correspondingly, the cover plate 112 has two positioning holes 113. The two positioning pins 4 correspond one-to-one with the two positioning holes 113, forming a stable position for the fixture body 110 from both sides. This prevents the pressure holding fixture 100 from shifting or shaking during inspection, providing a stable basis for inspecting the service life of the pressure holding fixture 100 and improving inspection accuracy. In other embodiments, the number of positioning pins 4 can also be three, four, five, etc., and the number of positioning holes 113 can also be three, four, five, etc., which is not specifically limited here.

[0060] In this embodiment, the height of the support member 3 is adjustable, so that the distance between the base 1 and the support seat 2 is adjustable. This improves the compatibility of the opening and closing handle inspection device with different models of pressure holding fixtures 100, reduces replacement costs, and ensures that the first handle 101 is precisely aligned with the first limiting component 6 and the second handle 102 is precisely aligned with the second limiting component 7 during inspection, thus ensuring inspection stability.

[0061] In this embodiment, the support member 3 includes an adjusting fastener, a first column and a second column that are nested together. Both the first and second columns have adjusting holes spaced apart along their height. The adjusting fastener passes through the corresponding adjusting holes to fix the relative position of the first and second columns. The height can be easily adjusted to change the distance between the base 1 and the support 2, adapting to pressure-holding fixtures 100 of different heights. Diverse inspection needs can be met without replacing the support member 3, improving the adaptability of the opening / closing handle inspection device to pressure-holding fixtures 100 of different specifications, ensuring accurate alignment during inspection, and reducing inspection costs.

[0062] In this embodiment, the support member 3 extends along a direction perpendicular to the first direction, which can stably connect the base 1 and the support seat 2, ensuring that the base 1 and the support seat 2 remain parallel and spaced apart, avoiding the displacement of the pressure holding fixture 100 due to the tilt of the support member 3, ensuring the stability of the pressure holding fixture 100 inspection process, and improving the reliability of the inspection.

[0063] In this embodiment, there are four support members 3. The base 1 is a rectangular piece, and the four support members 3 are respectively set at the four corners of the base 1. They provide even support to the support seat 2 from the four ends of the base 1, ensuring that the base 1 and the support seat 2 always maintain a parallel and stable interval. This prevents the pressure holding fixture 100° from shifting due to support imbalance during inspection, thus improving inspection reliability. In other embodiments, the number of support members 3 can also be six, eight, etc., and no specific limitation is made here.

[0064] In this embodiment, the handle opening / closing inspection device further includes a counting sensor and a controller. The counting sensor is used to detect the first number of reciprocating movements of the first limiting component 6 and the second limiting component 7. The counting sensor is communicatively connected to the controller, which receives the first number of movements and converts it into the second number of opening / closing movements of the first handle 101 and the second handle 102. The counting sensor generates the first number of movements when the first limiting component 6 and the second limiting component 7 move synchronously in opposite directions once, and also generates the first number of movements when the first limiting component 6 and the second limiting component 7 move synchronously towards each other once. The first number of movements is transmitted to the controller, which combines and converts these two sets of movements into the second number of opening / closing movements of the first handle 101 and the second handle 102 once. This achieves accurate counting of the number of handle opening / closing movements, avoids errors in manual statistics, provides accurate data for determining the service life of the pressure-holding fixture 100, and further improves the reliability of the test results.

[0065] In this embodiment, the handle opening and closing inspection device also includes a display screen, which is communicatively connected to the controller. The display screen is used to display the second count information in real time. The display screen of the handle opening and closing inspection device is communicatively connected to the controller and can display the second count information converted from the first count information in real time. Operators can intuitively grasp the total number of opening and closing times of the first handle 101 and the second handle 102 without additional querying, facilitating timely and accurate judgment of whether the pressure-holding fixture 100 has reached its service life threshold, improving the convenience of the inspection operation and the timeliness of data acquisition.

[0066] In this embodiment, the bottom of the base 1 is provided with an anti-slip pad. The anti-slip pad can increase the friction between the opening and closing handle inspection device and the placement surface, preventing the opening and closing handle inspection device from shifting or sliding during the inspection process, ensuring the stability of the pressure holding fixture 100 during inspection, providing a solid foundation for the precise opening and closing movement of the first handle 101 and the second handle 102, and further ensuring the accuracy of the inspection results.
