[0030] Refer to Figures 1 to 4 Describe a spring washer torsion test tooling according to an embodiment of the present invention.
[0031] As shown Figures 1 to 4 in the figure, the torsion test tooling for spring washers includes a fixing assembly 100, the fixing assembly 100 includes a first fixing member 110 and a second fixing member 120, and the second fixing member 120 is arranged at one end of the first fixing member 110; a clamping assembly 200, the clamping assembly 200 is connected to the fixing assembly 100, the clamping assembly 200 includes a first clamping member 210 and a second clamping member 220, the first clamping member 210 is arranged on the first fixing member 110, the second clamping member 220 is slidably connected to the second fixing member 120, the second clamping member 220 can slide in the direction of approaching and departing from the first clamping member 210, and the second clamping member 220 and the first clamping member 210 are used for clamping the spring washer 10; a scale 221 is arranged on the second clamping member 220 along the sliding direction, and an occlusion part 121 is arranged on the second fixing member 120, and the occlusion part 121 is used for indicating the data of the scale 221 to position the clamping position of the spring washer 10.
[0032] As shown Figure 1 in the figure, the second fixing member 120 is arranged at the upper end of the first fixing member 110, and the second fixing member 120 is located at the right end of the first fixing member 110, the first clamping member 210 is arranged at the left end of the first fixing member 110, the second clamping member 220 is slidably connected to the second fixing member 120, and the second fixing member 120 is located at the upper end of the first fixing member 110. Specifically, the second clamping member 220 is slidably connected to the second fixing member 120, and the second clamping member 220 can move in the left - right direction to approach or depart from the first clamping member 210. A scale 221 is further arranged on the second clamping member 220, and the scale 221 extends in the left - right direction. Correspondingly, an occlusion part 121 for occluding the scale 221 is arranged on the second fixing member 120. When the second clamping member 220 moves relative to the second fixing member 120, the occlusion part 121 will occlude part of the dimension as the second clamping member 220 moves, so as to indicate the length data on the scale 221. Thus, through the given size of the spring washer 10, the contact length with the spring washer 10 is calculated, the position of the second clamping member 220 is adjusted to make the data displayed on the scale 221 correspond to the calculated contact length, and then the spring washer 10 is fixed by the first clamping member 210 and the second clamping member 220, so as to carry out the torsion test of the spring washer 10 while ensuring the accurate clamping position, and meet the torsion test requirements of spring washers 10 with different specifications.
[0033] It should be noted that the spring washer 10 is a circular metal gasket with elastic properties. It is usually made of elastic materials such as steel or stainless steel and has the ability to bend and rebound. The main function of the spring washer 10 is to provide additional elasticity and buffering effect. It is used to form an elastic cushion layer between bolts, nuts or other fasteners and workpieces. It can be used to provide additional fastening force, reduce vibration and impact load, maintain the fastening state of the fasteners and prevent loosening, and solve problems such as gaps, uneven surfaces or uneven force distribution between the fasteners and workpieces. Therefore, it is widely used in the field of mechanical assembly and fastening.
[0034] In some specific embodiments of the present invention, the first fixing member 110 and the second fixing member 120 are connected by a pin. As Figures 1 to 3 shown, a connection groove is opened at the right end of the first fixing member 110, and pin holes are opened on both sides of the connection groove in the front-back direction of the coaxial eyes. A connection protrusion is provided at the right end of the second fixing member 120, and a pin hole is opened in the connection protrusion in the front-back direction. Place the connection protrusion in the connection groove, align the pin hole on the second fixing member 120 with the pin hole on the first fixing member 110, and insert the pin to achieve the connection between the first fixing member 110 and the second fixing member 120.
[0035] In some specific embodiments of the present invention, a first limiting groove 211 is opened on the first clamping member 210, and a second limiting groove 222 is opened on the second clamping member 220. The first limiting groove 211 and the second limiting groove 222 are used to accommodate the spring washer 10.
[0036] As Figure 1 and Figure 2 shown, a first limiting groove 211 is opened on the first clamping member 210, and the first limiting groove 211 is arranged to the right. Of course, the first limiting groove 211 can also be a through groove that penetrates the first clamping member 210 from left to right. Correspondingly, a second limiting groove 222 is provided on the second clamping member 220. Specifically, the upper ends of the first clamping member 210 and the second clamping member 220 are on the same horizontal plane, that is, the first limiting groove 211 and the second limiting groove 222 are on the same horizontal line, and this horizontal line is in the same direction as the extension direction of the second clamping member 220. Thus, the spring washer 10 is placed on the support points restricted by the first limiting groove 211 and the second limiting groove 222 to restrict the clamping position of the spring washer 10.
[0037] In some specific embodiments of the present invention, a first fastener is provided on the first clamping member 210, and a second fastener is provided on the second clamping member 220. The first clamping member 210 fixes the spring washer 10 on the first clamping member 210 through the first fastener, and the second clamping member 220 fixes the spring washer 10 on the second clamping member 220 through the second fastener.
[0038] AsFigure 2 and Figure 4 As shown in Figure 4 , a first through hole 212 is provided at the front end of the first limiting groove 211. The first through hole 212 extends from the front wall surface of the first clamping member 210 backward to the inner wall of the first limiting groove 211, and the first fastener is inserted into the first through hole 212. Similarly, a second through hole 224 is provided at the front end of the second limiting groove 222. The second through hole 224 extends from the front wall surface of the second clamping member 220 backward to the inner wall of the second limiting groove 222, and the second fastener is inserted into the second through hole 224.
[0039] In some specific embodiments of the present invention, the first fastener is a bolt, and the second fastener is a bolt. The first fastener is inserted into the first through hole 212 from the front end backward, and its rear end abuts the spring washer 10 against the inner wall of the first limiting groove 211 opposite to the first through hole 212. Locking the bolt can fix the spring washer 10 on the first clamping member 210. Specifically, threads can be provided on the inner wall of the first through hole 212, and through the cooperation of the threads on the inner wall of the first through hole 212 and the bolt, the locking of one end of the spring washer 10 is achieved. Similarly, the second fastener is inserted into the second through hole 224 from the front end backward, and its rear end abuts the spring washer 10 against the inner wall of the second limiting groove 222 opposite to the second through hole 224. Locking the bolt can fix the spring washer 10 on the second clamping member 220. Specifically, threads can be provided on the inner wall of the second through hole 224, and through the cooperation of the threads on the inner wall of the second through hole 224 and the bolt, the locking of the other end of the spring washer 10 is achieved.
[0040] In some specific embodiments of the present invention, the first fixing member 110 includes a connecting portion 111 and a holding portion 112. One end of the connecting portion 111 is connected to the first clamping member 210, and the other end is connected to the holding portion 112. The second fixing member 120 is provided at one end of the holding portion 112 away from the connecting portion 111.
[0041] As Figure 2 shown, the connecting portion 111 is provided at the left end of the holding portion 112, and a first clamping portion is connected to the left end of the connecting portion 111. Among them, the first clamping portion is arranged in the vertical direction, and the holding portion 112 can facilitate the operator to hold, so as to apply sufficient pressure to twist the spring washer 10.
[0042] In some specific embodiments of the present invention, the second fixing member 120 includes a plurality of positioning posts 122 extending along the sliding direction, and the second clamping member 220 includes a positioning groove 223 extending along the sliding direction. The number of the positioning grooves 223 corresponds to that of the positioning posts 122, and each positioning post 122 is inserted into the corresponding positioning groove 223 to define the sliding direction of the second clamping member 220.
[0043] As Figure 3 and Figure 4As shown in the figure, the second fixing member 120 is provided with four positioning posts 122 in the left-right direction. The four positioning posts 122 are arranged in two layers, with two positioning posts 122 in each layer. Correspondingly, the second clamping member 220 is provided with four positioning grooves 223 in the left-right direction, and the four positioning grooves 223 respectively correspond to one positioning post 122. Insert the second clamping member 220 from the left end of the second fixing member 120 so that the four positioning grooves 223 are respectively sleeved on the corresponding positioning posts 122. Under the restriction of the positioning posts 122, the second clamping member 220 can only move along the extension direction of the positioning posts 122, that is, the second clamping member 220 can only move in the left-right direction to approach or move away from the first clamping member 210.
[0044] Specifically, the second clamping member 220 is integrally inserted into the second fixing member 120. A scale 221 is arranged on the front side wall of the second clamping member 220 in the left-right direction, and the scale on the scale 221 extends in the left-right direction. The front side wall of the second fixing member 120 covers the front end of the second clamping member 220, thus forming an occlusion part 121. When the second clamping member 220 slides in the left-right direction, the occlusion part 121 can partially occlude the scale 221. Therefore, the distance between the first clamping member 210 and the second clamping member 220 is restricted by moving the second clamping member 220, and the clamping position of the spring washer 10 is accurately restricted by the value on the scale 221.
[0045] Of course, the positioning posts 122 can also be provided with one positioning post 122, two positioning posts 122, three positioning posts 122, and five positioning posts 122. When there is one positioning post 122, the positioning post 122 is a regular figure or a special-shaped figure with a non-circular cross-section. Correspondingly, the positioning grooves 223 can also be provided with one, two, three, and five. Among them, the cross-section of the positioning groove 223 corresponds to the cross-section of the positioning post 122.
[0046] In some specific embodiments of the present invention, the second limiting groove 222 is a strip-shaped groove extending along the sliding direction of the second clamping member 220.
[0047] As Figure 4 shown, the second limiting groove 222 is a strip-shaped groove extending in the left-right direction. Specifically, the second limiting groove 222 extends from the left end to the right end of the second clamping member 220. Further, the second through hole 224 is opened at the left end of the scale 221. The second through hole 224 penetrates the front wall surface of the second clamping member 220 and extends into the second limiting groove 222. Among them, the bottom of the second limiting groove 222 is deeper than the second through hole 224 to ensure that when the spring washer 10 is placed in the second limiting groove 222, it can be on the projection of the second through hole 224 along the extension direction, so as to ensure that the second fastener passing through the second through hole 224 can smoothly lock the spring washer 10 on the second clamping member 220.
[0048] Similarly, in the first clamping member 210, the bottom of the first limiting groove 211 is deeper than the first through hole 212, so as to ensure that when the spring washer 10 is placed in the first limiting groove 211, it can be on the projection of the first through hole 212 along the extending direction, thereby ensuring that the first fastener passing through the first through hole 212 can smoothly lock the spring washer 10 on the first clamping member 210.
[0049] In some specific embodiments of the present invention, the connecting portion 111 has a relief groove 1111, as Figure 2 shown, the relief groove 1111 is arc-shaped. Specifically, the relief groove 1111 is recessed downward to form an arc-shaped groove adapted to the spring washer 10.
[0050] In some specific embodiments of the present invention, according to the size of the given spring washer 10, the contact length with the spring washer 10 is calculated, the position of the second clamping member 220 is adjusted to make the data displayed on the scale 221 correspond to the calculated data, and then the spring washer 10 is placed in the first limiting groove 211 and the second limiting groove 222. The first fastener passes through the first through hole 212 to lock the spring washer 10 on the first clamping member 210, and the second fastener passes through the second through hole 224 to lock the spring washer 10 on the second clamping member 220. Thus, the torsion test of the spring washer 10 is carried out while ensuring the accurate clamping position, meeting the torsion test requirements of spring washers 10 of different specifications.
[0051] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
