DETAILED DESCRIPTION

[0032] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 5 In an embodiment of the present invention, a pull-out force test fixture includes a base 10, and a fixing assembly 20 and a driving assembly 30 respectively mounted on the base 10, wherein the fixing assembly 20 performs a fixing operation on the first arm 51 of the hinge 50 to be tested so that it is fixed to the base 10; and further includes a testing assembly 40, the main body of which is mounted on the driving assembly 30, and the testing end of the testing assembly 40 is transmission-connected to the second arm 52 of the hinge 50 to be tested, thereby operating the driving assembly 30, and driving the second arm 52 of the hinge 50 to be tested to rotate through the transmission connection of the testing assembly 40, so that the testing assembly 40 can measure the rotational torque of the hinge 50 to be tested.

[0034] Specifically, to facilitate and quickly test the hinge, a test fixture is preferably provided. The first arm 51 of the hinge is fixed to the base 10 using the fixing assembly 20, maintaining a secure and immobile state. The second arm 52 is then driven by the driving assembly 30, allowing it to rotate a certain angle relative to the first arm 51, completing the hinge's opening and closing operation.

[0035] Secondly, the test assembly 40 can be installed on the drive assembly 30. By utilizing the driving force of the drive assembly 30, the test assembly 40 can drive the second arm 52 to rotate, so that the test assembly 40 can test the torque used by the hinge during the opening and closing process.

[0036] Secondly, the pull-out force test fixture is used to measure the opening and closing forces of hinge products to ensure they meet customer requirements. Based on the existing digital push-pull force gauge, the fixture is customized according to the specific structure and shape of the hinge product. It can better simulate the actual opening and closing state of the product during use, making the measurement simpler, faster, and more accurate.

[0037] like Figure 1 and Figure 3 As shown, preferably, the fixing assembly 20 is provided with a mounting bracket 21, one end of the mounting bracket 21 is fixed to the base 10, and the other end thereof is provided with a limiting column 22, and the limiting column 22 is used to pass through the mounting hole of the first arm 51 of the hinge 50 to be tested, thereby forming a limiting connection for the first arm 51.

[0038] Specifically, the limiting post 22 can limit the first arm 51 so that it can be placed at a predetermined position on the mounting bracket 21. Specifically, after a worker takes the hinge 50 to be tested, he or she aligns the mounting hole of the first arm 51 with the limiting post 22, places the first arm 51 on the limiting post 22, and abuts the mounting bracket 21, waiting for the abutment block 26 to engage.

[0039] like Figure 1 、 Figure 4 and Figure 5 As shown, preferably, the fixing assembly 20 is further provided with a clamping bracket 23, a clamping cylinder 25 and a clamping block 26. One end of the clamping bracket 23 is mounted on the base 10, and the other end thereof is used to mount the clamping cylinder 25. The clamping block 26 is fixed to the piston end of the clamping cylinder 25, so that it moves toward the placement bracket 21 under the drive of the clamping cylinder 25, and clamps the first arm 51, thereby fixing the first arm 51 at the preset position of the placement bracket 21.

[0040] Specifically, since the second arm 52 of the hinge 50 to be tested needs to rotate relative to the first arm 51, the first arm 51 needs to be fixed. The fixing effect cannot be achieved by only using the placement bracket 21, so a clamping bracket 23 can be provided and driven by the clamping cylinder 25, so that the clamping block 26 can press the first arm 51 against the placement bracket 21 to achieve the corresponding fixing operation. When the hinge 50 to be tested needs to be removed, it is only necessary to reverse the clamping cylinder 25 to move the clamping block 26 in the opposite direction and disengage it from the abutment position of the first arm 51, and then withdraw the first arm 51 from the limiting column 22 to remove the hinge 50 to be tested.

[0041] Secondly, in order to install the clamping cylinder 25 and the auxiliary slider 27, it is preferred to set the clamping bracket 23 as two brackets installed on the base 10 at a certain distance from each other, so that the clamping cylinder 25 can be installed on the two brackets through the cross plate, so that the two sides of the auxiliary slider 27 can be respectively embedded in the auxiliary slide grooves 24 of the two brackets.

[0042] like Figure 2 As shown, preferably, the fixing assembly 20 is further provided with an auxiliary slider 27, one end of the auxiliary slider 27 is fixed to the piston end of the clamping cylinder 25, and the other end is fixed to the clamping block 26, and auxiliary guide rails 29 are provided on both sides of the auxiliary slider 27, and the clamping bracket 23 is provided with an auxiliary slide groove 24 on one side relative to the auxiliary guide rail 29, and the auxiliary guide rail 29 and the auxiliary slide groove 24 cooperate with each other to form a linear sliding system.

[0043] Specifically, in order to make the movement of the abutting block 26 more accurate, an auxiliary slider 27 may be provided, and the auxiliary guide rail 29 may be engaged with the auxiliary slide 24 to form a linear sliding system, so that the auxiliary slider 27 can accurately move linearly within the auxiliary slide 24, and thus accurately abut against the first arm 51 under the drive of the abutting cylinder 25. Since the limiting post 22 usually extends a certain distance from the mounting hole of the first arm 51 when limiting the connection with the first arm 51, an avoidance hole may be provided at the corresponding position of the abutting block 26. The provision of the auxiliary slider 27 allows the avoidance hole to be accurately fitted over the protruding portion of the limiting post 22, thereby achieving a good fixing effect on the first arm 51.

[0044] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, preferably, the driving assembly 30 is provided with a driving bracket 31, a rotating arm 32 and a driving cylinder 34, one end of the driving bracket 31 is fixed to the base 10, and the other end thereof is rotatably connected to one end of the rotating arm 32, and the other end of the rotating arm 32 is installed with a test assembly 40; the driving cylinder 34 is rotatably connected to the base 10, and its piston end is transmission-connected to the rotating arm 32, thereby driving the rotating arm 32 to rotate, and then the test assembly 40 drives the second arm 52 of the hinge 50 to be tested to rotate synchronously.

[0045] Specifically, to facilitate installation of the test assembly 40 and testing of the hinge 50 to be tested, the drive brackets 31 are preferably arranged as two brackets spaced a certain distance apart and mounted on the base 10. The rotating arm 32 is similarly provided with two arms, each rotatably connected to the two brackets. This allows the test assembly 40 to be mounted on the two arms at positions corresponding to the second arm 52 via corresponding cross plates, allowing the test end of the test assembly 40 to drive the second arm 52, thereby testing the rotational torque of the second arm 52.

[0046] like Figure 3 As shown, preferably, the rotating arm 32 is configured to be L-shaped, and a first rotating shaft 33 is provided at the bend of the L-shape, and the piston end of the driving cylinder 34 is rotatably connected to the first rotating shaft 33, thereby realizing a transmission connection to the rotating arm 32. The base 10 is provided with a second rotating shaft 11, and the driving cylinder 34 is rotatably connected to the base 10 via the second rotating shaft 11.

[0047] Specifically, since the driving cylinder 34 needs to drive the rotating arm 32 to rotate a certain angle, the driving cylinder 34 cannot be completely fixed on the base 10 or the rotating arm 32. A corresponding first rotating shaft 33 and a second rotating shaft 11 can be set so that the cylinder body of the driving cylinder 34 is rotatably connected to the base 10 through the second rotating shaft 11, and its piston rod is rotatably connected to the rotating arm 32 through the first rotating shaft 33.

[0048] like Figures 3 to 5 As shown, preferably, the base 10 is further provided with a support column 12, one end of the support column 12 is fixedly connected to the base 10, and the other end thereof forms a free end and supports the rotating arm 32 after rotating to a certain angle.

[0049] Specifically, in order to prevent the driving cylinder 34 from causing the rotating arm 32 to rotate at an excessively large angle when driving the rotating arm 32 to rotate, thereby damaging the hinge 50 to be tested, a support column 12 can be set below the position after the rotating arm 32 rotates, so as to support and limit the rotating arm 32, thereby preventing the rotating arm 32 from rotating at an excessively large angle and exceeding the preset rotation angle of the hinge 50 to be tested.

[0050] like Figures 3 to 5 As shown, preferably, the main body of the test assembly 40 is mounted on the drive assembly 30, and its testing end is detachably engaged with the second arm 52 of the hinge 50 to be tested. The test end of the test assembly 40 is further provided with a clamping block 41, one end of which is fixedly connected to the test end, and a clamping slot 42 is provided on the side of the clamping block 41 facing the second arm 52, so that the second arm 52 can be inserted into the clamping slot 42, thereby allowing the clamping block 41 to drive the second arm 52 to rotate.

[0051] Specifically, in order to facilitate the driving of the second arm 52, it is preferred to set a card block 41 at the test end and set a card slot 42 on the side facing the second arm 52. During the test, the worker can insert the free end of the second arm 52 into the card slot 42 so that it can drive the second arm 52. The test component 40 can adopt a digital push-pull force gauge produced by Adberg Company among the existing products. The driving cylinder 34 can adopt a stainless steel mini cylinder produced by STNC Company, model number is TGA32X250. The tightening cylinder 25 can adopt a conventional cylinder produced by STNC Company, model number is TGN40X50.

[0052] This utility model primarily employs a digital push-pull force gauge secured to a fixture, powered by air generated by an air compressor. Two sets of two-position, five-way lever valves are used to control the abutting cylinder 25 and the rotating cylinder, respectively. This allows the cylinders to operate normally, driving the rotating arm 32 to rotate back and forth through a certain angle, thereby opening and closing the hinge 50 under test. Simultaneously, because the test end of the test assembly 40 is transmission-connected to the second arm 52 of the hinge 50 under test and drives the second arm 52 to rotate, the rotational torque of the hinge 50 under test can be measured. This means that the opening and closing torques of the hinge 50 under test can be measured, thereby strictly controlling the torque of the product, meeting production requirements, and improving product quality.

[0053] During use, two sets of two-position, five-way hand valves (not shown) can be installed on either side of the test fixture to control the abutting cylinder 25 and the driving cylinder 34, respectively. The two-position, five-way hand valves can be STNC's existing model TG2521B-08. Connect the air supply line from an external air compressor to the main air connection on the equipment to drive the cylinders.

[0054] In the initial state, the abutting cylinder 25 is in a retracted state, driving the abutting block 26 away from the mounting bracket 21, leaving a certain gap at the front end of the mounting bracket 21 to facilitate the placement of the hinge 50 to be tested. The driving cylinder 34 is also in a retracted state, driving the rotating arm 32 to rotate at a certain angle.

[0055] Then, the second arm 52 of the hinge 50 to be tested, which is in the open state, is moved upward a certain distance so that it passes through the slot 42 of the block 41 at the test end of the test assembly 40. Then, the first arm 51 of the hinge 50 to be tested is placed on the mounting bracket 21, and the mounting hole of the first arm 51 is sleeved on the limit column 22, so that the placement position of the first arm 51 meets the preset position requirement. Then, the two-position five-way hand valve is used to open the tightening cylinder 25, which is operated to drive the tightening block 26 to move in the direction of the mounting bracket 21 and finally abut against the first arm 51, thereby accurately fixing the first arm 51 in the preset position of the mounting bracket 21.

[0056] After the fixation is completed, the driving cylinder 34 can be opened through another two-position five-way hand valve to operate the driving cylinder 34, driving the rotating arm 32 to rotate, thereby causing the test assembly 40 on the rotating arm 32 to rotate synchronously, so that the block 41 at the test end can drive the second arm 52 to rotate synchronously. At this time, the test assembly 40 can test the torque for closing the hinge 50 to be tested and record this value.

[0057] When the hinge 50 to be tested rotates to a preset angle, the limiting anti-collision blocks between the first arm 51 and the second arm 52 thereof will abut against each other, so that the driving cylinder 34 reaches the maximum stroke and stops driving.

[0058] Afterwards, the worker records the test value of the test component 40, performs a zeroing operation, and then reversely opens the drive cylinder 34 to shrink the drive cylinder 34, driving the rotating arm 32 to rotate in the opposite direction, so that the test end of the test component 40 drives the second arm 52 to rotate in the opposite direction by a corresponding angle, so that the test component 40 can test the torque for opening and stretching the hinge 50 to be tested, and record this value.

[0059] Finally, the clamping cylinder 25 is opened in reverse, so that it drives the clamping block 26 to retreat a certain distance and retract from the first arm 51 where the bracket 21 is placed, thereby loosening the first arm 51, allowing the worker to take the hinge 50 to be tested, withdraw the limit column 22, and thus take out the hinge 50 to be tested to complete the test.

[0060] This pull-out force test fixture is customizable based on the specific structure and shape of the hinge, making it easier to secure the fixture to the product and providing more accurate measurements. Its simple structure, easy operation, and high practicality significantly improve work efficiency.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
