[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0025] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0026] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.
[0027] like Figure 1 and Figure 2 As shown, the positioning fixture according to the embodiment of the present application includes a fixed base 10, on which are provided a plurality of first limiting grooves 11 and a plurality of second limiting grooves 21. The plurality of first limiting grooves 11 and the plurality of second limiting grooves 21 are arranged in sequence and spaced apart along the length direction of the fixed base 10. The first limiting grooves 11 are used to fix parts, and the second limiting grooves 21 are used to fix gaskets.
[0028] Specifically, a plurality of first limiting grooves 11 and a plurality of second limiting grooves 21 are provided on the fixing seat 10, and the plurality of first limiting grooves 11 and the plurality of second limiting grooves 21 are arranged in sequence along the length direction of the fixing seat 10, that is, the first limiting groove 11, the second limiting groove 21, the first limiting groove 11, the second limiting groove 21, the first limiting groove 11, the second limiting groove 21, the first limiting groove 11, the second limiting groove 21, the first limiting groove 11, and the second limiting groove 21 are arranged in this sequence, and the first limiting groove 11 is used to fix the parts, and the second limiting groove 21 is used to fix the gasket. In this way, when the parts are strung together, the parts can be placed in the first limiting grooves 11 in sequence, and the gaskets can be placed in the second limiting grooves 21 in sequence, and then the stringing rod can be used to string the parts and the gaskets together, and then the stringing rod can be taken out with both hands.
[0029] According to the positioning fixture of the embodiment of the present application, the parts transportation and clamping process is simplified, the operating efficiency is improved, and at the same time the number of containers that need to be temporarily stored in the processing area after the parts are transported to the heat treatment workshop is reduced, thereby reducing production costs.
[0030] like Figure 1 and Figure 2As shown, according to the positioning jig of the embodiment of the present application, a plurality of partitions 20 are provided on the fixing seat 10, a first limiting groove 11 is defined between two adjacent partitions 20, a second limiting groove 21 is provided on the partition 20, and the thickness of the second limiting groove 21 on the partition 20 passes through the partition 20.
[0031] In detail, a plurality of partitions 20 are provided on the fixing seat 10, and a first limiting groove 11 is defined between two adjacent partitions 20, and a second limiting groove 21 is provided on the partition 20. The thickness of the second limiting groove 21 on the partition 20 passes through the partition 20. In this way, when placing parts, all required parts are first placed in the corresponding first limiting groove 11, and then the gasket is placed in the corresponding second limiting groove 21. This can simplify the overall structural setting of the positioning fixture and reduce the difficulty of molding.
[0032] like Figure 2 and Figure 3 As shown, in some embodiments, the second limiting groove 21 is configured as an arc groove, and the central angle of the arc groove is greater than 180°. It can be understood that when the central angle of the arc groove is greater than 180°, more than half of the area of the gasket can be positioned and limited by the second limiting groove 21, thereby increasing the accuracy and stability of the second limiting groove 21 limiting the gasket. For example, the central angle of the arc groove is 200°, 210°, 220°, 230°, and 240°, etc.
[0033] According to the positioning fixture of the embodiment of the present application, a guide portion 30 is further provided on the fixing seat 10 . The guide portion 30 is provided on one side of the second limiting groove 21 and smoothly transitions with the side wall defining the second limiting groove 21 .
[0034] like Figure 1 and Figure 3 As shown, according to the positioning jig of the embodiment of the present application, a guide portion 30 is further provided on the fixing seat 10. The guide portion 30 is provided on one side of the second limiting groove 21 and smoothly transitions with the side wall that defines the second limiting groove 21. Since the gasket is relatively thin, the contact area between the positioning jig and the gasket can be increased by utilizing the guide portion 30, thereby improving the positioning effect of the gasket and avoiding difficulty in fixing and inefficiency caused by the gasket being skewed when the stringing rod is stringing materials.
[0035] In a specific embodiment, the component is a ratchet.
[0036] like Figure 1 As shown, in some embodiments, the partition 20 includes a first section 22 , a second section 23 and a third section 24 , the first section 22 , the second section 23 and the third section 24 are connected in sequence and their heights decrease in sequence, and the second limiting groove 21 is located in the third section 24 .
[0037] In detail, since the size of the gasket is smaller than the size of the part, in order to make the gasket easier to place and reduce the difficulty of placement, the first section 22, the second section 23 and the third section 24 are connected in sequence and the heights are reduced successively, and the second limiting groove 21 is located in the third section 24. In this way, while the part can be positioned and limited, the difficulty of placing the gasket is also reduced.
[0038] like Figure 1 and Figure 2 As shown, in some embodiments, both ends of the fixing seat 10 in the length direction are provided with guide grooves 41 , and the guide grooves 41 are connected to the adjacent first limiting grooves 11 .
[0039] In detail, guide grooves 41 are provided at both ends of the fixing seat 10 in the length direction, and the guide grooves 41 are connected to the adjacent first limiting grooves 11. In this way, the guide grooves 41 can be used to limit and position the stringing rod, thereby reducing the difficulty of aligning the stringing rod with the assembly holes on the parts and the assembly holes on the gaskets.
[0040] like Figure 1 and Figure 2 As shown, in some embodiments, a baffle 40 is provided on the fixing seat 10, and the baffle 40 defines a guide groove 41, and the guide groove 41 penetrates the baffle 40 in the thickness direction of the baffle 40. It can be understood that such a setting can facilitate the limiting and positioning of the string rod, and at the same time simplify the structural setting and processing difficulty of the positioning fixture.
[0041] In some embodiments, the thickness of the baffle 40 is greater than that of the partition 20. In detail, since the length of the stringing rod is large, increasing the thickness of the baffle 40 can increase the contact area between the baffle 40 and the stringing rod, thereby increasing the accuracy and stability of positioning and limiting the stringing rod.
[0042] In some embodiments, the fixing seat 10, the partition plate 20 and the baffle plate 40 are integrally formed, so that the processing cost of the positioning fixture can be reduced and the overall structural strength of the positioning fixture can be improved.
[0043] In some embodiments, the fixing seat 10, the partition plate 20 and the baffle plate 40 are made of polyoxymethylene. Polyoxymethylene is also commonly known as polyoxymethylene, which has hardness, strength and rigidity similar to that of racing car, and has good fatigue resistance, so the service life of the positioning fixture can be extended.
