Referring to fig. 1, 2 and 3, an assembly fixture 10 according to an embodiment of the present utility model is used for fixing a sensor 20, so as to assemble the sensor 20, where the sensor 20 may be a pressure sensor or the like. The assembly jig 10 includes a base 100 and a clamping mechanism 200, the clamping mechanism 200 being disposed on the base 100, the clamping mechanism 200 being configured to clamp the sensor 20.

Referring to fig. 1, 2 and 3, in some embodiments, the base 100 may be generally cylindrical, the base 100 is configured to be fixed on a table, and the base 100 has two surfaces in a thickness direction, which may be denoted as a first surface 110 and a second surface 120, and obviously, the first surface 110 and the second surface 120 are spaced apart and face opposite in the thickness direction of the base 100, and both the first surface 110 and the second surface 120 are circular surfaces. The second surface 120 may be carried on the table in contact with the table, i.e., the table carries the entire base 100 by supporting the second surface 120. The first surface 110 of the base 100 is provided with a sliding groove 130, the sliding groove 130 is formed by a part of the first surface 110 being recessed to a set depth, and the sliding groove 130 is spaced from the second surface 120 by a certain distance, such that the sliding groove 130 does not extend to the second surface 120. The chute 130 may pass through the center of the base 100 such that the base 100 may be symmetrically disposed with respect to the chute 130. Obviously, the chute 130 passes through the center of the first surface 110, so that the first surface 110 is symmetrically disposed with respect to the chute 130.

The bottom wall surface of the chute 130 is arranged at intervals from the first surface 110 along the thickness direction, the bottom wall surface of the chute 130 is provided with a mounting hole 150 along the thickness direction of the base 100, and the mounting hole 150 penetrates through the whole base 100 along the thickness direction, so that an opening exists on the second surface 120 of the mounting hole 150, and the mounting hole 150 is used for fixing the sensor 20. For example, the sensor 20 may be threaded into the mounting hole 150. The mounting hole 150 is opened at a central position of the base 100 such that a center line of the mounting hole 150 is disposed in line with an axis of the base 100.

Referring to fig. 1, 2 and 3, in some embodiments, the base 100 is provided with two adjusting slots 140, and the two adjusting slots 140 may be spaced apart by 180 ° in the circumferential direction of the base 100, such that a line connecting the two adjusting slots 140 passes through the center of the base 100 and is perpendicular to the axis of the base 100. The adjustment groove 140 penetrates the entire base 100 in the thickness direction such that the adjustment groove 140 has openings on both the first surface 110 and the second surface 120, and the adjustment groove 140 extends a certain length in the interval direction of the two adjustment grooves 140. The adjustment groove 140 has an opening on a side circumferential surface of the base 100, and it is apparent that the side circumferential surface of the base 100 is connected between the first surface 110 and the second surface 120, and it is also understood that the adjustment groove 140 is formed by the side circumferential surface of the base 100 with a certain depth spaced apart in the interval direction of the two adjustment grooves 140. The interval direction of the two adjusting grooves 140 may be perpendicular to the extending direction of the sliding groove 130, and when the extending direction of the sliding groove 130 is the front-back direction, the interval direction of the adjusting grooves 140 is the left-right direction; when the sliding groove 130 extends in the left-right direction, the interval direction of the adjusting groove 140 is the front-rear direction.

Referring to fig. 1, 2 and 3, the adjustment groove 140 includes two parts, which are respectively denoted as a first groove 141 and a second groove 142, the first groove 141 and the second groove 142 are communicated with each other, the first groove 141 has an opening on the first surface 110, the second groove 142 has an opening on the second surface 120, a cross section of the first groove 141 may be larger than a second cross section, and in a thickness direction of the base 100, the cross sections of both the first groove 141 and the second groove 142 may be maintained unchanged, and the base 100 may further have a step surface 143 in view of the presence of the adjustment groove 140, the step surface 143 being located at a communication place of both the first groove 141 and the second groove 142. The entire adjustment groove 140 can be regarded as one stepped groove due to the presence of the stepped surface 143, the stepped surface 143 being understood as the groove bottom surface of the first groove 141, and the second groove 142 being formed by recessing the groove bottom surface of the second groove 142 by a set depth. The length of the first groove 141 in the thickness direction of the base 100 may be greater than the length of the second groove 142 in the thickness direction of the base 100.

In some embodiments, the clamping mechanism 200 includes two sliders 210, the sliders 210 can slidably engage the chute 130 such that the two sliders 210 can move toward and away from each other on the base 100, and the mounting hole 150 is located between the two sliders 210. When the sensor 20 is inserted into the mounting hole 150, the two sliders 210 can move in opposite directions, and when the two sliders 210 are simultaneously abutted against the sensor 20, the sensor 20 is clamped between the two sliders 210, so that the sensor 20 is fixed by the assembly jig 10. When the two sliders 210 move apart, the two sliders 210 move away from the sensor 20 and out of contact with the sensor 20, so that the sliders 210 can release the clamping of the sensor 20, the assembled sensor 20 can be removed from the mounting holes 150 for unloading, and the sensor 20 to be assembled can be inserted into the mounting holes 150 for further fixing. In other embodiments, the sliding grooves 130 may be disposed on the sliding blocks 210, and the number of the sliding blocks 210 may be three or four, and each sliding block 210 slides along the radial direction of the first surface 110, so long as the sliding block 210 is ensured to slide relative to the base 100 and clamp the sensor 20.

Referring to fig. 1, 2 and 3, in some embodiments, the assembly jig 10 further includes a first fastener 310, and the first fastener 310 may be a bolt or a screw. The bottom wall surface of the chute 130 of the base 100 is provided with a circular hole 160 extending along the thickness direction of the base 100, and the circular hole 160 and the second surface 120 may be spaced apart from each other along the thickness direction of the base 100, so that the circular hole 160 does not extend to the second surface 120, and thus the circular hole 160 does not have an opening on the second surface 120. The slider 210 is provided with an elongated hole 213, an extending direction of the elongated hole 213 is the same as an extending direction of the chute 130, and the elongated hole 213 can correspond to the circular hole 160, so that the first fastener 310 can be simultaneously inserted into the circular hole 160 and the elongated hole 213. When the first fastener 310 is inserted into the circular hole 160 and is screwed with the base 100, the slider 210 is fixed relative to the base 100 and cannot slide relatively; when the first fastener 310 is released from the threaded connection with the base 100 and out of the circular hole 160, the interference of the first fastener 310 with the slider 210 can be eliminated, thereby enabling the slider 210 to slide in the slider 210 with respect to the base 100. When the sliding block 210 slides a certain distance relative to the base 100, the sliding is stopped, and the first fastening member 310 can be inserted into the elongated hole 213 and the circular hole 160 again, so as to change the installation position of the first fastening member 310 relative to the elongated hole 213 and also change the fixing position of the sliding block 210 relative to the base 100.

Therefore, after the sliding blocks 210 move towards each other or away from the base 100 by a set distance, the installation position of the sliding blocks 210 relative to the base 100 is changed, and the distance between the two sliding blocks 210 is also changed, so that the distance between the two sliding blocks 210 can be adapted to different types of sensors 20. For example, when the assembly jig 10 is used to assemble a sensor 20 having a larger cross-sectional size, the two sliders 210 may be moved apart such that the space between the two sliders 210 is relatively large to fit the sensor 20 having a larger cross-sectional size; when a larger cross-sectional size sensor 20 is available for the spacing between the two sliders 210, the sliders 210 may be secured by the first fastener 310 and the larger cross-sectional size sensor 20 may be sandwiched between the two sliders 210 for further assembly. For another example, when the assembly fixture 10 is used to assemble a sensor 20 with a smaller cross-sectional size, the two sliders 210 may be moved toward each other such that the spacing between the two sliders 210 is relatively small to accommodate the sensor 20 with a smaller cross-sectional size; when a smaller cross-sectional size sensor 20 is available for the spacing between the two sliders 210, the sliders 210 may be secured by a first fastener 310 and the smaller cross-sectional size sensor 20 may be sandwiched between the two sliders 210 for further assembly. For another example, when the cross section of the sensor 20 is circular (as shown in fig. 4) or regular polygon (as shown in fig. 2), the distance between the two sliders 210 can be adjusted by the above method, so that the sensor 20 with different shapes will be clamped between the two sliders 210 for the next assembly. Therefore, by adjusting the interval between the two sliding blocks 210, the interval can be adapted to the sensors 20 with different sizes and shapes, so that the assembly jig 10 can be suitable for assembling different types of sensors 20, and the universality of the assembly jig 10 is improved.

After the universality of the assembly jig 10 is improved, the same assembly jig 10 can be suitable for the assembly of different types of sensors 20, and the different types of sensors 20 do not need to be assembled through the different assembly jigs 10, so that the number of the assembly jigs 10 is reduced, the design and manufacturing cost of the assembly jigs 10 are reduced, and the assembly cost of the sensors 20 is finally reduced.

In some embodiments, the slider 210 has a first abutment surface 211 and a second abutment surface 212, the first abutment surface 211 and the second abutment surface 212 can abut the sensor 20 at the same time, the first abutment surface 211 and the second abutment surface 212 intersect at a set angle, for example, the angle at which the first abutment surface 211 and the second abutment surface 212 intersect may be an obtuse angle, such that the first abutment surface 211 and the second abutment surface 212 are connected to form a V-shape. Through setting up first butt face 211 and the second butt face 212 that the contained angle set up, first butt face 211 and second butt face 212 can both play fine centre gripping effect to regular polygon and circular shape sensor 20 to guarantee that assembly jig 10 has fine commonality, when the crossing angle of first butt face 211 and second butt face 212 is the obtuse angle, the assembly of multiple different grade type sensor 20 can be satisfied to slider 210 slip less distance.

In some embodiments, the assembly fixture 10 further includes a second fastener 320, where the second fastener 320 may be a bolt or a screw, and a circular fixing hole may be formed on the table, and when the second fastener 320 is simultaneously inserted into the adjusting slot 140 and the fixing hole, the base 100 and the entire assembly fixture 10 may be fixed on the table. In view of the fact that the adjustment slots 140 extend a certain length in the direction of the interval between the two adjustment slots 140, after the connection between the second fastening member 320 and the table is released, the base 100 can be moved a certain distance in the direction of the interval between the two adjustment slots 140, so that the mounting position of the base 100 relative to the base 100 in the direction of the interval between the adjustment slots 140 can be changed, and after the second fastening member 320 is connected with the table again, the mating position of the second fastening member 320 and the adjustment slot 140 can be changed. In view of the arrangement of the step surface 143, the nut of the second fastener 320 may be abutted against the step surface 143, thereby realizing the fixed connection of the second fastener 320 and the workbench.

If the extending direction of the slide groove 130 is seen as the left-right direction, and the interval direction of the two regulating grooves 140 is seen as the front-rear direction. By changing the positions of the two sliders 210 in the left-right direction, the assembly jig 10 can be adapted to the assembly of the sensors 20 of different sizes and shapes. By changing the position of the base 100 in the front-rear direction, the position of the assembly jig 10 in the front-rear direction can be adjusted, and the assembly jig 10 can be adapted to the assembly of the sensor 20 in different positions. Therefore, the assembly fixture 10 can make the assembly fixture 10 suitable for the assembly of the sensors 20 with different shapes, different sizes and different positions by adjusting the base 100 in the front-back direction and the sliding block 210 in the left-right direction, so as to finally improve the universality of the assembly fixture 10, reduce the number of the assembly fixtures 10, reduce the design and manufacturing cost of the assembly fixture 10 and finally reduce the assembly cost of the sensors 20.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
