For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to specific circumstances. Some embodiments of the present application will be described in detail below with reference to the drawings.

[0073] Please refer to Figure 1 、 Figure 2 and Figure 3 , an embodiment of the present application provides a clamping fixture 100, which is applied to a processing device (not shown in the figure) and is used to position the product 910 and adjust the angle of the product 910 so that the processing device can process, detect, etc. multiple structural features of the product 910 respectively. Among them, the processing device can be a processing machine tool, a drawing force detection device, a position degree detection device, etc., the product 910 can be a middle frame, a rear shell, a display module, etc. of electronic devices such as mobile phones and tablet computers, and the multiple structural features on the product 910 can be bumps, round holes, square holes, threaded holes, etc. For the convenience of understanding and description, in the embodiment of the present application, taking the processing device as a drawing force detection device, the product 910 as the rear shell of a mobile phone, and all the multiple structural features of the product 910 being threaded holes, and the processing device respectively performing drawing force tests on the multiple structural features of the product 910 as an example for description. Obviously, this is not a limitation of the embodiment of the present application.

[0074] In this embodiment, the clamping fixture 100 includes a base 10, a clamping mechanism 20 and a plug-in member 30.

[0075] The base 10 is used to connect with the processing device (not shown in the figure), and the base 10 is provided with a plurality of limiting holes 1121.

[0076] The clamping mechanism 20 includes a bearing component 21 and a pressing member 22. The bearing component 21 is rotatably arranged on the base 10. The bearing component 21 is used to bear and position the product 910. The bearing component 21 is provided with a plurality of insertion holes 2112a arranged at intervals. The plurality of insertion holes 2112a correspond to the plurality of limiting holes 1121 one by one, so as to form multiple groups of corresponding limiting holes 1121 and insertion holes 2112a. Each limiting hole 1121 is located on the moving path of the corresponding insertion hole 2112a. The pressing member 22 is detachably arranged on the bearing component 21. The pressing member 22 is used to press the product 910 tightly against the bearing component 21.

[0077] The plug-in member 30 is used to insert into the corresponding limiting hole 1121 and insertion hole 2112a when the bearing component 21 rotates by a preset angle, so as to limit the rotation of the bearing component 21.

[0078] Specifically, as Figure 3 shown, the product 910 has a first threaded hole 9101, a second threaded hole 9102 and a third threaded hole 9103. The first threaded hole 9101, the second threaded hole 9102 and the third threaded hole 9103 are all opened on the inner wall of the product 910. The inclination angle of the first threaded hole 9101 is 75 degrees, the inclination angle of the second threaded hole 9102 is 58 degrees, and the inclination angle of the third threaded hole 9103 is 70 degrees. When using the processing device to perform the pull-out force test on the first threaded hole 9101, the second threaded hole 9102 and the third threaded hole 9103 respectively, it is necessary to adjust the angle of the product 910 so that the first threaded hole 9101, the second threaded hole 9102 and the third threaded hole 9103 are respectively vertically upward, so as to facilitate the pulling head 920 of the processing device to be inserted into the first threaded hole 9101, the second threaded hole 9102 and the third threaded hole 9103 along the vertical direction respectively.

[0079] In this embodiment, the limiting holes 1121 and the insertion holes 2112a can both be correspondingly set to three. The three limiting holes 1121 and the three insertion holes 2112a respectively correspond to the adjustment angles of the first threaded hole 9101, the second threaded hole 9102, and the third threaded hole 9103. When using the processing device to perform the pulling force test on the first threaded hole 9101, the second threaded hole 9102, and the third threaded hole 9103 respectively, only need to position the product 910 between the bearing assembly 21 and the pressing member 22, and rotate the clamping mechanism 20 to make a corresponding set of limiting holes 1121 and insertion holes 2112a face each other. Then insert the insert 30 into the corresponding set of limiting holes 1121 and insertion holes 2112a and restrict the rotation of the bearing assembly 21. Then the corresponding first threaded hole 9101, second threaded hole 9102, or third threaded hole 9103 is adjusted to be vertically upward, thereby improving the efficiency of adjusting the angle of the product 910. In addition, the clamping fixture 100 of this embodiment can adjust multiple angles of the product 910 with only one set of fixtures, thereby reducing the fixture cost. Further, by setting that multiple insertion holes 2112a and multiple limiting holes 1121 correspond to each other one by one, and each limiting hole 1121 is located on the moving path of the corresponding insertion hole 2112a, it can be ensured that each set of insertion holes 2112a and limiting holes 1121 do not interfere with other sets of insertion holes 2112a and limiting holes 1121. Thus, multiple limiting holes 1121 can be densely arranged on the base 10 with a smaller size, and multiple insertion holes 2112a can be densely arranged on the bearing assembly 21 with a smaller size, which is beneficial to reducing the size of the clamping fixture 100.

[0080] It can be understood that the number and positions of the limiting holes 1121 and the insertion holes 2112a are specifically set according to the number, types, and inclination angles of the structural features of the product 910, and the present application does not make specific limitations thereto.

[0081] Please refer to Figure 2 and Figure 4 , in this embodiment, the base 10 includes a support frame 11, a support shaft 12, and a tensioning member 13. Multiple limiting holes 1121 are opened on the support frame 11; the support shaft 12 slidably passes through the support frame 11, the bearing assembly 21 is rotatably sleeved on the support shaft 12, and a contact portion 121 for abutting against the bearing assembly 21 is convexly provided on the circumferential side of one end of the support shaft 12 close to the bearing assembly 21; the tensioning member 13 is arranged at one end of the support shaft 12 far from the contact portion 121 and is connected to the support frame 11. The tensioning member 13 is used to drive the support shaft 12 to move, so that the contact portion 121 presses or releases the bearing assembly 21, thereby facilitating the adjustment of the tightness of the rotation of the bearing assembly 21.

[0082] In this embodiment, the support frame 11 includes a base plate 111 and two support members 112; a long through-hole 1111 is formed in the base plate 111, which facilitates the use of bolts (not shown in the figure) to pass through the long through-hole 1111 to connect with the processing device and facilitates the adjustment of the position of the base plate 111 relative to the processing device; the two support members 112 are arranged on the base plate 111 at intervals, and at least one support member 112 is provided with a plurality of limit holes 1121, and both of the two support members 112 are provided with through-holes 1122. The number of tension members 13 and support shafts 12 is two. The two support shafts 12 are respectively inserted through the two through-holes 1122. The bearing assembly 21 is rotatably sleeved on the two support shafts 12 and is located between the two support members 112. The two tension members 13 are respectively arranged on the two support shafts 12. By providing two tension members 13 and two support shafts 12 to adjust the tightness of the rotation of the bearing assembly 21 from both sides, it is beneficial to improve the accuracy and stability of adjusting the tightness of the rotation of the bearing assembly 21.

[0083] In this embodiment, the support frame 11 further includes two limiting blocks 113. The two limiting blocks 113 are respectively arranged on the sides of the two support members 112 away from each other. Each of the two limiting blocks 113 is provided with a limiting hole 1131. Each limiting hole 1131 is disposed opposite to and communicated with the adjacent through-hole 1122. The two tension members 13, the two support shafts 12, the two limiting holes 1131 and the two through-holes 1122 correspond to each other one by one. Each support shaft 12 passes through the corresponding through-hole 1122 and the corresponding limiting hole 1131 and extends to the side of the corresponding support member 112 away from the other support member 112. An abutting portion 121 protrudes from one end of the support shaft 12 located between the two support members 112. The two tension members 13 can both be knobs. The tension member 13 is threadedly connected to the end of the support shaft 12 away from the abutting portion 121 and abuts against the corresponding limiting block 113. The portion of the support shaft 12 corresponding to the limiting hole 1131 has a limiting portion 122. The cross-sectional shapes of the limiting hole 1131 and the limiting portion 122 can both be square. The cooperation between the limiting hole 1131 and the limiting portion 122 can limit the rotation of the support shaft 12. When the two tension members 13 are screwed, the two tension members 13 slide in the corresponding through-holes 1122 and limiting holes 1131 respectively, thereby driving the abutting portion 121 to press or loosen the bearing assembly 21.

[0084] In some other embodiments, the tension member 13 can also be a power member such as a telescopic cylinder (not shown in the figure). The tension member 13 is installed on the support frame 11 and is connected to the support shaft 12. The tension member 13 drives the support shaft 12 to move to press or loosen the bearing assembly 21. The embodiments of the present application do not make specific limitations on this.

[0085] In this embodiment, the base 10 further includes two washers 14. The two washers 14 are respectively sleeved on the two tension members 13 and are located between the abutting portion 121 and the bearing assembly 21. The abutting portion 121 presses the bearing assembly 21 tightly by squeezing the corresponding washer 14. The washer 14 can be made of a flexible material such as rubber. The washer 14 can reduce the friction between the abutting portion 121 and the bearing assembly 21, thereby facilitating the reduction of the probability of damaging the abutting portion 121 and the bearing assembly 21.

[0086] Please further refer to Figure 5 In this embodiment, the bearing assembly 21 includes a bearing seat 211, a plurality of first limiting members 212, a second limiting member 213, and an elastic pressing member 214. The bearing seat 211 is rotatably arranged on the base 10. The bearing seat 211 is used for bearing the product 910. A plurality of insertion holes 2112a are formed in the bearing seat 211. The plurality of first limiting members 212 are arranged on the bearing seat 211 at intervals along the first direction. The plurality of first limiting members 212 are used for abutting and limiting the product 910 in the first direction. The second limiting member 213 is arranged on the bearing seat 211 and is located on one side of the plurality of first limiting members 212. The elastic pressing member 214 is arranged on the bearing seat 211, and the elastic pressing member 214 and the second limiting member 213 are arranged at intervals along the second direction. The elastic pressing member 214 is used for pressing the product 910 against the second limiting member 213 in the second direction, wherein the first direction and the second direction intersect. In this way, by arranging the plurality of first limiting members 212 to abut and limit the product 910 in the first direction, and arranging the elastic pressing member 214 to press the product 910 against the second limiting member 213 in the second direction, the bearing assembly 21 can limit the product 910 in two different directions, thereby facilitating the improvement of the accuracy of the bearing assembly 21 in bearing and positioning the product 910.

[0087] In this embodiment, the first direction is Figure 1 and Figure 5 the X-axis direction in Figure 1 and Figure 5 the Y-axis direction in

[0088] In this embodiment, the elastic pressing member 214 includes a connecting block 2141 and a telescopic member 2142. The connecting block 2141 is arranged on the bearing seat 211 and is arranged at intervals with the second limiting member 213 along the second direction. The telescopic member 2142 can be a ball plunger or a ball head plunger. The telescopic member 2142 is inserted into the connecting block 2141 and is arranged opposite to the second limiting member 213.

[0089] In this embodiment, the bearing seat 211 includes a bearing plate 2111 and two rotating blocks 2112, the two rotating blocks 2112 are arranged at one side of the bearing plate 2111, and the two rotating blocks 2112 are respectively sleeved on the two support shafts 12 and located between the two support members 112. The bearing seat 211, multiple first limiting members 212, second limiting members 213 and elastic pressing members 214 are all arranged on the side of the bearing plate 2111 away from the two rotating blocks 2112, and the cover pressing member 22 is detachably arranged on the bearing plate 2111. The carrier plate 2111 is on the side away from the two rotating blocks 2112, and a plurality of limiting holes 1121 are provided on the two support members 112. A plurality of plug-in holes 2112a are correspondingly provided on the two rotating blocks 2112. The number of the plug-in members 30 can be two. When the carrier assembly 21 rotates by a preset angle, the two plug-in members 30 are respectively inserted into the corresponding limiting holes 1121 and the plug-in holes 2112a from both sides, thereby facilitating improving the accuracy of the clamping fixture 100 in adjusting the angle of the product 910.

[0090] In some other embodiments, a plurality of limiting holes 1121 may be provided on only one supporting member 112, and a plurality of corresponding plug-in holes 2112a may be provided on an adjacent rotating block 2112. Correspondingly, the number of plug-in components 30 is one. When the supporting component 21 rotates by a preset angle, a plug-in component 30 is inserted from one side into a corresponding set of limiting holes 1121 and plug-in holes 2112a. The embodiment of the present application does not make any specific limitation on this.

[0091] In this embodiment, a positioning protrusion 2111a is protruded on the supporting component 21, and the positioning protrusion 2111a is specifically protruded on the side of the supporting plate 2111 away from the two rotating blocks 2112. A positioning hole 221 is opened on the cover pressing member 22. When the cover pressing member 22 is pressed on the supporting component 21, the positioning protrusion 2111a is inserted into the positioning hole 221 to position the cover pressing member 22 relative to the supporting component 21, thereby facilitating improving the accuracy of the cover pressing member 22 pressing on the supporting component 21.

[0092] In some other embodiments, the positioning protrusion 2111a may also be protruded on the cover pressing member 22, and correspondingly, the positioning hole 221 is opened on the supporting component 21. The positioning protrusion 2111a inserted into the positioning hole 221 can also position the cover pressing member 22 relative to the supporting component 21. The embodiments of the present application do not make specific limitations on this.

[0093] In this embodiment, the number of the positioning protrusions 2111a and the number of the positioning holes 221 are both multiple, and the multiple positioning protrusions 2111a correspond to the multiple positioning holes 221 one by one, and the sizes of the multiple positioning protrusions 2111a are different, and each positioning protrusion 2111a is plugged and matched with the corresponding positioning hole 221. In this way, it can effectively prevent the operator from installing the cover pressing member 22 upside down due to operating errors.

[0094] In this embodiment, a portion of the positioning holes 221 may be waist-shaped holes, thereby effectively reducing the probability of the cover pressing member 22 being stuck due to frequent clamping.

[0095] In this embodiment, the cover pressing piece 22 is a hollow structure, which is beneficial to reduce the weight of the cover pressing piece 22 and facilitates the tension head 920 of the processing device to pass through the cover pressing piece 22 and connect with the first threaded hole 9101, the second threaded hole 9102 or the third threaded hole 9103.

The locking member 23 is specifically rotatably arranged on the supporting plate 2111. The locking member 23 can be a cam handle. When the cover pressing member 22 presses the product 910 against the supporting component 21, the locking member 23 locks the cover pressing member 22, thereby facilitating improving the stability of the cover pressing member 22 pressing the product 910.

[0097] In some other embodiments, the locking member 23 may also be a locking screw (not shown), a cylinder connected to a pressure block (not shown), etc., which is not specifically limited in the embodiments of the present application.

[0098] Please refer again Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, both support members 112 have a first limiting surface 1123, and the first limiting surface 1123 is used to abut and limit the bearing assembly 21 when the bearing assembly 21 rotates to a first preset angle. Specifically, the first preset angle is the angle at which the bearing assembly 21 drives the product 910 to rotate when the first threaded hole 9101 is vertically upward. When the bearing assembly 21 rotates to the first preset angle, the first limiting surface 1123 abuts and sticks to the bearing plate 2111 of the bearing assembly 21, thereby facilitating the accurate insertion of the plug-in component 30 into the corresponding set of limiting holes 1121 and plug-in holes 2112a, and facilitating the support frame 11 to support the bearing assembly 21 when the processing device performs a pull-out force test on the corresponding structural features of the product 910.

[0099] In this embodiment, the clamping fixture 100 further includes a sliding member 40 and a driving member 50. The sliding member 40 is slidably disposed on the substrate 111, and the sliding member 40 has a second limiting surface 41; the driving member 50 is disposed on the support frame 11 and connected to the sliding member 40, and the driving member 50 is used to drive the sliding member 40 to move so that the second limiting surface 41 abuts against and limits the bearing assembly 21 when the bearing assembly 21 rotates by a second preset angle. Specifically, the second preset angle is the angle by which the bearing assembly 21 drives the product 910 to rotate when the second threaded hole 9102 is vertically upward. The sliding direction of the sliding member 40 intersects with the rotating direction of the bearing assembly 21. The second limiting surface 41 is located on the side of the sliding member 40 facing the bearing assembly 21. When the bearing assembly 21 rotates by the second preset angle, the driving member 50 drives the sliding member 40 to move towards the bearing assembly 21 so that the second limiting surface 41 abuts and adheres tightly to the bearing plate 2111 of the bearing assembly 21, thereby facilitating the sliding member 40 to support the bearing assembly 21 when the processing device performs a pulling force test on the corresponding structural features of the product 910.

[0100] In this embodiment, the driving member 50 includes an assembly block 51 and an adjusting member 52. The assembly block 51 is disposed on the substrate 111 and is located on the sliding path of the sliding member 40. The adjusting member 52 can be an adjusting bolt. The adjusting member 52 passes through the assembly block 51 and is threadedly connected to the sliding member 40. By screwing the adjusting member 52, the adjusting member 52 can drive the sliding member 40 to slide on the substrate 111. In this way, the structure of the driving member 50 is simple and the cost is low.

[0101] In some other embodiments, the driving member 50 can also be a telescopic cylinder, an electric push rod, a linear module, etc., and the embodiments of the present application do not make specific limitations thereto.

[0102] In this embodiment, the clamping fixture 100 further includes a guiding member 60. The guiding member 60 is disposed on the substrate 111. A sliding channel 61 is formed on the side of the guiding member 60 facing the substrate 111. The sliding member 40 is located in the sliding channel 61. The guiding member 60 has a third limiting surface 62, and the third limiting surface 62 is used to abut against and limit the bearing assembly 21 when the bearing assembly 21 rotates by a third preset angle. Specifically, the third preset angle is the angle by which the bearing assembly 21 drives the product 910 to rotate when the third threaded hole 9103 is vertically upward. When the driving member 50 drives the sliding member 40 to slide, the sliding channel 61 guides the sliding direction of the sliding member 40, thereby facilitating improving the accuracy of the driving member 50 to drive the sliding member 40 to slide. When the bearing assembly 21 rotates by the third preset angle, the third limiting surface 62 abuts and adheres tightly to the bearing plate 2111 of the bearing assembly 21, thereby facilitating the plug-in member 30 to accurately insert into a corresponding group of limiting holes 1121 and plug-in holes 2112a, and facilitating the guiding member 60 to support the bearing assembly 21 when the processing device performs a pulling force test on the corresponding structural features of the product 910.

[0103] In this embodiment, the sliding member 40 is provided with a receiving groove 42 extending along the sliding direction of the sliding member 40. The clamping fixture 100 further includes a resisting member 70 and an elastic member 80. The resisting member 70 passes through the guiding member 60 and extends into one end of the receiving groove 42 close to the driving member 50. The elastic member 80 can be a spring. The elastic member 80 is disposed in the receiving groove 42, and both ends of the elastic member 80 are respectively connected to the resisting member 70 and the groove wall of the receiving groove 42 away from the driving member 50. Specifically, the guiding member 60 is provided with a penetrating hole 63 facing one end of the receiving groove 42 close to the driving member 50. The resisting member 70 passes through the penetrating hole 63 and extends into one end of the receiving groove 42 close to the driving member 50. When the clamping fixture 100 is in a non-use state, the elastic member 80 drives the sliding member 40 to move away from the driving member 50, so as to be able to tension the sliding member 40 and avoid the sliding member 40 from shaking when the clamping fixture 100 is moved; when the driving member 50 drives the sliding member 40 to move towards the bearing assembly 21 so that the second limiting surface 41 abuts against the bearing assembly 21, since there may be a connection gap between the driving member 50 and the sliding member 40 in a threaded connection, the sliding member 40 may not move in place, resulting in the second limiting surface 41 not being able to tightly adhere to the bearing assembly 21. By providing the elastic member 80 to tension the sliding member 40, the sliding member 40 is more tightly connected to the driving member 50, thereby effectively reducing the probability that the second limiting surface 41 cannot tightly adhere to the bearing assembly 21 due to the sliding member 40 not moving in place.

[0104] In summary, the clamping fixture 100 of the embodiment of the present application is provided with the bearing assembly 21 rotatably disposed on the base 10, and a plurality of limiting holes 1121 are opened on the base 10. A plurality of insertion holes 2112a are opened on the bearing assembly 21, and the plurality of insertion holes 2112a respectively correspond to the plurality of limiting holes 1121 one by one. When it is necessary to adjust the angle of the product 910, only need to position the product 910 between the bearing assembly 21 and the pressing member 22, and rotate the clamping mechanism 20 to align a corresponding set of limiting holes 1121 and insertion holes 2112a, and then insert the inserting member 30 into the corresponding set of limiting holes 1121 and insertion holes 2112a to limit the rotation of the bearing assembly 21. The operation is simple and the efficiency of adjusting the angle of the product 910 is improved; in addition, the clamping fixture 100 of the embodiment of the present application can adjust the angles of multiple products 910 with only one set of fixtures, thereby reducing the fixture cost; further, by setting each limiting hole 1121 to be located on the moving path of the corresponding insertion hole 2112a, the set of insertion holes 2112a and limiting holes 1121 do not interfere with other sets of insertion holes 2112a and limiting holes 1121, so that a plurality of limiting holes 1121 can be densely opened on the base 10 with a smaller size, and a plurality of insertion holes 2112a can be densely opened on the bearing assembly 21 with a smaller size, which is beneficial to reducing the size of the clamping fixture 100.
