Description

Technical Field

[0001] The present application relates to the technical field of product positioning tooling, and in particular to a clamping fixture. Background Art

[0002] At present, in the process of automated assembly line operation, products are mostly fixed by fixtures to facilitate their positioning and prevent unnecessary displacement of products in subsequent processing or testing and assembly processes. With the progress of society, electronic products such as automobiles, semiconductors, mobile phones, and computers are updated faster and faster, and the industry has higher and higher requirements for the manufacturing accuracy of fixtures. The way to mechanically clamp products using fixtures also needs to be easier to operate.

[0003] In the prior art, there are usually two ways to fix products: one is to position the product through the product's own holes; the other is to position the product through the product's edges. However, positioning the product through holes first requires that the product itself has positioning holes, which is not universal, so the product can only be positioned through the product's edges if there are no positioning holes. However, positioning through the product's edges requires machining a contoured groove on the clamping fixture, placing the product in the contoured groove, and then using tools such as cylinders, springs, or magnets to cooperate with the side walls of the contoured groove to achieve positioning. However, this positioning method not only occupies a large space for the clamping fixture, but also requires simultaneous action in both the X and Y directions, resulting in inconvenient operation and a higher overall cost for the clamping fixture. Utility Model Content

[0004] Based on this, the purpose of this application is to provide a clamping fixture to solve the problems of large space occupation, inconvenient operation and high cost when using existing clamping fixtures to position products.

[0005] According to one aspect of the present application, a clamping fixture is provided, comprising:

[0007] A slider, movably connected to the fixture body, a first limit assembly being fixedly provided on the slider, and an inclined groove being provided on the slider and being inclined relative to the first direction, and a second limit assembly being slidably provided in the inclined groove;

[0008] The slider can move relative to the fixture body along a first direction together with the first limiting assembly under the action of an external force, so as to clamp or release the product together with the first side wall in the first direction; at the same time, in response to the movement of the slider, the second limiting assembly can move along a second direction perpendicular to the first direction under the guidance of the inclined groove, so as to clamp or release the product together with the second side wall in the second direction.

[0014] In one embodiment, the bottom end of the connecting block has a sliding member, the sliding member of the first limiting assembly is fixedly connected to the sliding block, and the sliding member of the second limiting assembly is slidably disposed in the inclined groove provided in the sliding block.

[0015] In one embodiment, the clamping fixture also includes a handle, which includes a gripping portion and a connecting portion that are connected to each other, the connecting portion is connected to the slider and is movably connected to the fixture body; the gripping portion is used to withstand the external force so that the handle can move relative to the fixture body and drive the slider to move relative to the fixture body.

[0016] In one embodiment, the connecting portion has a rotating shaft, which is rotatably connected to the fixture body. The connecting portion also has an eccentric shaft eccentrically arranged with respect to the rotating shaft. The eccentric shaft is connected to the slider via a connecting rod, one end of the connecting rod is rotatably connected to the eccentric shaft, and the other end of the connecting rod is rotatably connected to the slider.

[0017] In one of the embodiments, the handle can be rotated relative to the jig body to a locking position or a releasing position with the central axis of the rotating shaft as the rotation axis, and an avoidance groove is provided on the side of the jig body. When the handle is in the locking position or the releasing position, at least a portion of the gripping portion can be accommodated in the avoidance groove.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0029] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0030] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0031] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0032] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0033] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0034] As described in the background technology, in the process of automated assembly line operation, products are usually fixed by fixtures to facilitate their positioning and prevent unnecessary displacement of products in subsequent processing steps or test and assembly steps. In the prior art, the way to fix products is usually to position the products through the holes of the products themselves, or to position the products through the edges of the products.

[0035] However, positioning products through holes first requires that the products themselves have positioning holes, which is not universal. Therefore, if there are no positioning holes, the products can only be positioned by the sides of the products. However, positioning by the sides of the products requires machining of profiling grooves on the fixture, placing the products in the profiling grooves, and then using tools such as cylinders, springs or magnets to cooperate with the side walls of the profiling grooves to achieve positioning. This positioning method not only occupies a large space for the fixture, but also requires simultaneous action in both the X and Y directions, resulting in inconvenient operation and a higher overall cost for the fixture.

[0036] Therefore, in order to solve the above-mentioned series of problems, the present application provides a clamping fixture that can achieve product positioning with a simple structure and convenient operation.

[0037] The following takes the product to be positioned as an electronic product as an example, and takes the clamping fixture used to position the electronic product in the test assembly production line as an example to explain the structure of the clamping fixture in the present application. It can be understood that in other embodiments, the clamping fixture of the present application is not limited to being used only in the test assembly production line to position the electronic product, but can also be used in any production line to position any product, which is not limited here.

[0038] See also Figure 1 and Figure 2 , Figure 1 FIG. 1 is a schematic diagram showing the appearance of a clamping fixture 10 provided in an embodiment of the present application. Figure 2 An exploded schematic diagram of a clamping fixture 10 provided in one embodiment of the present application is shown. The clamping fixture 10 provided in one embodiment of the present application includes a fixture body 100, a slider 200, a first limit assembly 300, a second limit assembly 400 and a handle 500. The fixture body 100 is provided with a receiving groove 101 for receiving the product. The receiving groove 101 is rectangular in the embodiment shown in the figure, and has a first side wall 101a and a second side wall 101b perpendicular to each other; the slider 200 is movably connected to the fixture body 100, the first limiting component 300 is fixedly arranged on the slider 200, and the second limiting component 400 is slidably connected to the slider 200. The first limiting component 300 is used to limit the product in the first direction with the first side wall 101a, and the second limiting component 400 is used to limit the product in the second direction with the second side wall 101b; the handle 500 is connected to the slider 200 for the operator to hold, so that the operator can easily apply an external force to the slider 200 to drive the slider 200 to move along the first direction (the X direction shown in the figure).

[0039] When the slider 200 moves along the first direction, the first limiting assembly 300 can move along the first direction together with the slider 200, so as to clamp or release the product together with the first side wall 101a in the first direction; at the same time, in response to the movement of the slider 200, the second limiting assembly 400 can move along a second direction perpendicular to the first direction (the Y direction as shown in the figure), so as to clamp or release the product together with the second side wall 101b in the second direction, thereby achieving the positioning of the product.

[0040] Specifically, see Figure 3The handle 500 includes a gripping portion 510 and a connecting portion 520 connected to each other, the connecting portion 520 is connected to the slider 200 and is movably connected to the fixture body 100; the gripping portion 510 is used for being held by a user and bearing the external force applied by the user, so that the handle 500 can move relative to the fixture body 100 and drive the slider 200 to move relative to the fixture body 100.

[0041] Combination Figures 1 to 3 As shown, in one embodiment, the handle 500 is rotatably connected to the fixture body 100 and the slider 200, and the connecting portion 520 of the handle 500 is provided with a rotating shaft 530, and the central axis of the rotating shaft 530 is along the vertical direction shown in the figure ( Figure 3 The handle 500 extends in the Z direction as shown in the figure, and the rotating shaft 530 is rotatably connected to the fixture body 100, so that the handle 500 can be rotated around the central axis of the rotating shaft 530 relative to the fixture body 100 to a locking position 102 or a releasing position 103. When the handle 500 is rotated to the locking position 102, the first limiting assembly 300 is located at a maximum stroke close to the first side wall 101a, and the second limiting assembly 400 is located at a maximum stroke close to the second side wall 101b, so that the product can be clamped; when the handle 500 is rotated to the releasing position 103, the first limiting assembly 300 is located at a maximum stroke away from the first side wall 101a, and the second limiting assembly 400 is located at a maximum stroke away from the second side wall 101b, so that the product can be released.

[0042] It is understandable that the handle 500 is not limited to being rotatably connected to the slider 200, nor is it limited to being rotatably connected to the fixture body 100. For example, the handle 500 can also be only movable in the first direction, thereby directly pulling the slider 200 to move in the first direction. Even the handle 500 may not be provided, and the operator directly pulls the slider 200 to move in the first direction, as long as it is convenient to pull the slider 200, and the above is not limited.

[0043] More specifically, see Figure 3 The handle 500 is rotatably connected to the slider 200 through a connecting rod 600, wherein the connecting portion 520 of the handle 500 is provided with an eccentric shaft 540 eccentrically arranged with the rotating shaft 530, one end of the connecting rod 600 is rotatably connected to the eccentric shaft 540, and the other end of the connecting rod 600 away from the eccentric shaft 540 is rotatably connected to the slider 200. As long as the handle 500 is rotated, the connecting rod 600 and the slider 200 can be linked, so that the connecting rod 600 can pull the slider 200 to move along the first direction, thereby realizing the driving of the slider 200 with a relatively simple mechanical structure.

[0044] For details on the connection structure between the first limiting assembly 300, the second limiting assembly 400 and the slider 200, please continue to refer to Figure 3In one embodiment, a mounting hole 201 and an inclined groove 202 are provided on the slider 200, and the bottom end of the first position-limiting component 300 is fixedly inserted in the mounting hole 201, so that the first position-limiting component 300 is fixedly arranged on the slider 200. The inclined groove 202 is arranged obliquely relative to the first direction, preferably along the diagonal line of the slider 200, and the bottom end of the second position-limiting component 400 is slidably arranged in the inclined groove 202. In this way, when the slider 200 moves along the first direction, the first position-limiting component 300 can move along the first direction with the slider 200, and the second position-limiting component 400 can move along the second direction at the same time under the guidance of the inclined groove 202, so as to realize positioning of the product in the first direction and the second direction at the same time.

[0045] Combination Figure 2 , Figure 3 and Figure 4 As shown, assuming Figure 2 The state shown in is the initial state of the clamping fixture 10. Figure 2 When the handle 500 is rotated in a clockwise direction, the shaft 530 at the connection portion 520 of the handle 500 will rotate synchronously around its own central axis, and the eccentric shaft 540 will also rotate synchronously around the central axis of the shaft 530, thereby driving one end of the connecting rod 600 to rotate around the central axis of the shaft 530, and the other end will rotate relative to the slider 200, and push the slider 200 to move in the first direction away from the handle 500. At this time, the first limiting assembly 300 moves toward the direction close to the first side wall 101a, and the second limiting assembly 400 moves toward the direction close to the second side wall 101b under the guidance of the inclined groove 202, thereby achieving the clamping of the product;

[0046] On the contrary, assuming Figure 4 The state shown in is the initial state of the clamping fixture 10. When the handle 500 is rotated counterclockwise, the rotating shaft 530 located at the connecting portion 520 of the handle 500 will synchronously reverse around its own central axis, and the eccentric shaft 540 will also synchronously reverse around the central axis of the rotating shaft 530, thereby driving one end of the connecting rod 600 to reverse around the central axis of the rotating shaft 530, and the other end will reverse relative to the slider 200, and pull the slider 200 to move along the first direction toward the handle 500. At this time, the first limiting assembly 300 moves in a direction away from the first side wall 101a, and the second limiting assembly 400 moves in a direction away from the second side wall 101b under the guidance of the inclined groove 202, thereby achieving the release of the product.

[0047] In this way, through the above-mentioned arrangement, it is possible to use a simple mechanical structure to drive the slider 200 to move in one direction to drive the first limit assembly 300 and the second limit assembly 400 to move simultaneously in two directions. Therefore, the clamping fixture 10 provided in the present application is easy to operate, and there is no need to use a cylinder. Instead, only the handle 500 needs to be turned to drive the first limit assembly 300 and the second limit assembly 400 to position the product simultaneously in two mutually perpendicular directions, thereby reducing the space occupied by the clamping fixture 10 and greatly saving the production cost of the clamping fixture 10.

[0048] Specifically regarding the structures of the first position-limiting assembly 300 and the second position-limiting assembly 400 , the structures of the first position-limiting assembly 300 and the second position-limiting assembly 400 are completely the same. Figure 3 FIG. 4 shows a schematic diagram of the structure of the first limiting assembly 300 or the second limiting assembly 400. Figure 3 As shown in , the first limiting assembly 300 and the second limiting assembly 400 respectively include a connecting block 310 and a clamping block 320, wherein the connecting block 310 is connected to the slider 200, and the clamping block 320 is connected to the corresponding connecting block 310. The clamping block 320 of the first limiting assembly 300 is used to limit the product in the first direction with the first side wall 101a, and the clamping block 320 of the second limiting assembly 400 is used to limit the product in the second direction with the second side wall 101b. Preferably, the clamping block 320 is connected to the corresponding connecting block 310 through an elastic element 330 (such as a spring), and the purpose of setting the elastic element 330 is that when the clamping block 320 contacts the product to clamp and limit the product, the elastic element 330 can be compressed to provide an elastic force that causes the clamping block 320 to press the product, so that the product can provide a certain buffer when it contacts the clamping block 320, avoiding rigid contact between the clamping block 320 and the product, so as to effectively prevent the product from being damaged due to excessive pressure when being clamped.

[0049] Further, on the basis of the above embodiment, the block 320 is also slidably connected to the corresponding connection block 310, specifically, the connection block 310 is provided with a guide groove 310a, and the block 320 is slidably limited in the guide groove 310a provided in the corresponding connection block 310. For example, the connection block 310 of the first limit assembly 300 is provided with a guide groove 310a extending along the first direction, and the connection block 310 of the second limit assembly 400 is provided with a guide groove 310a extending along the second direction, so that the block 320 of the first limit assembly 300 is slidably limited in the corresponding guide groove 310a and can only slide along the first direction, and the block 320 of the second limit assembly 400 is slidably limited in the corresponding guide groove 310a and can only slide along the second direction, so that the block 320 will not be offset when moving, and can be closely attached to the product when clamping the product, avoiding the situation of loose positioning of the product.

[0050] Please continue reading Figure 3 In one embodiment, the connection block 310 includes a body 311, a cover 312 and a sliding member 313. The guide groove 310a is provided on the body 311 and penetrates the body 311. The cover 312 is detachably provided on one side of the body 311 and closes one end of the guide groove 310a. The block 320 is connected to the cover 312 through an elastic element 330. The sliding member 313 is provided at the bottom of the body 311. The sliding member 313 of the first limiting assembly 300 is inserted into the mounting hole 201 provided in the slider 200. The sliding member 313 of the second limiting assembly 400 is slidably provided in the guide groove 310a of the connection block 310. Preferably, the sliding member 313 of the second limiting assembly 400 can be a pulley, so that the pulley of the second sliding member 313 can reduce friction when moving in the guide groove 310a, so that the movement is smoother and the jamming is avoided.

[0051] Of course, it is understandable that the connecting block 310 can also be an integrally connected structure, which is not limited here, but the connecting block 310 is designed to be a structure composed of multiple parts as shown in the figure, which can be easily maintained. For example, when a component of the connecting block 310 has a problem, only the component can be replaced, thereby reducing waste and saving costs.

[0052] Please continue reading Figure 1 , Figure 2 and Figure 4In one embodiment, the fixture body 100 is a split structure, which includes a carrier plate 110 and a base 120. The carrier plate 110 is detachably arranged on the base 120, the slider 200 is installed in the base 120 and slidably connected to the base 120, and the receiving groove 101 is opened on the carrier plate 110. Specifically, in the embodiment shown in the figure, the carrier plate 110 has a first limit block 111 and a first mounting block 112 arranged relatively spaced apart along a first direction, and a second limit block 113 and a second mounting block 114 arranged relatively spaced apart along a second direction. The first limit block 111, the first mounting block 112, the second limit block 113 and the second mounting block 114 jointly surround the receiving groove 101, and the first limit block 111 forms a first side wall 101a on the side facing the first mounting block 112, and the second limit block 113 forms a second side wall 101b on the side facing the second mounting block 114. The first mounting block 112 and the second mounting block 114 are respectively hollow structures. When the slider 200 moves relative to the fixture body 100, the first limiting assembly 300 can be accommodated in the first mounting block 112 or at least partially exposed to the first mounting block 112, and the second limiting assembly 400 can be accommodated in the second mounting block 114 or at least partially exposed to the second mounting block 114. Specifically, when the product is clamped, the block 320 of the first limiting assembly 300 is at least partially exposed to the first mounting block 112, and the block 320 of the second limiting assembly 400 is at least partially exposed to the second mounting block 114; when the product is released, the block 320 of the first limiting assembly 300 is completely accommodated in the first mounting block 112, and the block 320 of the second limiting assembly 400 is completely accommodated in the second mounting block 114.

[0053] Regarding the structure of the base 120, please continue to refer to Figure 2 and Figure 4 The base 120 is provided with a mounting groove 120a, and the slider 200 is slidably disposed in the mounting groove 120a and can slide in the mounting groove 120a. The base 120 includes a base body 121 and a fixing block 122 detachably connected to the base body 121, and the rotating shaft 530 of the handle 500 is rotatably connected to the fixing block 122. By setting the fixing block 122 detachably connected to the base body 121, the handle 500 can be first installed on the fixing block 122, one end of the connecting rod 600 can be installed on the eccentric shaft 540 on the handle 500, and the slider 200 can be installed on the other end of the connecting rod 600, and then the above-assembled components can be assembled as a whole on the base body 121, so that the handle 500, the connecting rod 600 and the slider 200 can be easily disassembled and assembled, thereby improving the disassembly and assembly efficiency.

[0054] Furthermore, an avoidance groove 104 is also opened on the side of the base 120. When the handle 500 is rotated to the locking position 102 or the release position 103 relative to the fixture body 100, the gripping portion 510 of the handle 500 can be at least partially accommodated in the avoidance groove 104, so as to further save the overall volume and occupied space of the clamping fixture 10.

[0055] In addition, in order to lock the handle 500 when it is rotated to the locking position 102 or the release position 103, and to prevent the operator from accidentally touching the handle 500 and causing the handle 500 to rotate and cause an accident, as an improved implementation mode, the groove wall of the avoidance groove 104 is respectively provided with a first limiting hole (not shown in the figure) and a second limiting hole (not shown in the figure) at the positions of the locking position 102 and the release position 103, and a first limiting pin (not shown in the figure) is movably arranged in the first limiting hole, and the first limiting pin can move in the first limiting hole to be partially exposed in the first limiting hole or retracted into the first limiting hole; similarly, a second limiting pin (not shown in the figure) is movably arranged in the second limiting hole, and the second limiting pin can move in the second limiting hole to be partially exposed in the second limiting hole or retracted into the second limiting hole.

[0056] In this way, when the handle 500 is located in the avoidance groove 104 and in the locking position 102, the gripping portion 510 of the handle 500 can be limited in the locking position 102 and cannot be rotated by making the first limit pin portion exposed in the first limit hole; when the handle 500 is located in the avoidance groove 104 and in the release position 103, the gripping portion 510 of the handle 500 can be limited in the release position 103 and cannot be rotated by making the second limit pin portion exposed in the second limit hole, thereby limiting the handle 500 in the locking position 102 or the release position 103 respectively, thereby avoiding the operator's misoperation of the handle 500.

[0057] It should be noted that the fixture body 100 is not limited to the structure described in the above embodiment. For example, in other embodiments, the receiving groove 101 may be directly opened on the upper surface of the carrier plate 110, rather than forming the receiving groove 101 by setting the first limit block 111, the first mounting block 112, the second limit block 113 and the second mounting block 114. The fixture body 100 may also be an integrally formed structure, which is not limited to the above. However, the structure of the embodiment shown in the figure can make it easy for operators to disassemble and assemble the various components of the clamping fixture 10, and can facilitate replacement and maintenance, which is obviously a better embodiment.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
