Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, and in particular to a manually switch-controlled positioning fixture. Background Technology

[0002] In industrial production scenarios such as precision manufacturing, electronic processing, and component assembly, precise product positioning is a core element in ensuring processing accuracy and improving production efficiency. Specialized fixtures are needed to stably fix the product, ensuring the accuracy of subsequent processing and testing. Currently, mainstream fixture positioning solutions in the industry generally integrate positioning fixtures into processing and testing equipment, relying on cylinders and other drive systems in conjunction with multi-component transmission structures. However, these positioning fixtures are uniquely specific, dependent on the specific structural settings of the main equipment, limiting their mobility and versatility. Furthermore, cylinders and other drive equipment are costly, lack flexibility, and are complex to assemble and maintain, making them poorly adaptable to flexible production scenarios with multiple varieties and small batches, thus negatively impacting production efficiency. Simultaneously, existing positioning fixtures typically use mechanical rigidity to position and lock the workpiece, often resulting in indentations and other damage to the workpiece surface. In addition, current common clamps clamp and position the outer surfaces of opposite sides of the workpiece. For positioning hollow frame-shaped workpieces (such as battery frames), due to the thinness of the workpiece, the clamping force can cause deformation. Utility Model Content

[0047] Example 1

[0048] See Figures 1-9c This embodiment discloses a manually controlled positioning fixture, including: fixture body 1, pressure element 2, manual control switch 3 and elastic element 4.

[0049] The fixture body 1 is provided with a mounting hole 11, which is located at the upper end of the fixture body 1 and extends in the horizontal direction.

[0050] The pressing element 2 is provided with a driving hole 21, which is located at the upper end of the pressing element 2 and extends in the horizontal direction.

[0051] The hand switch 3 is sequentially inserted into the mounting hole 11 and the drive hole 21 in the horizontal direction; when the hand switch 3 moves in the first horizontal direction, the hand switch 3 presses the upper side of the inner wall of the drive hole 21 to lift the pressing element 2 away from the pressing position in the vertical direction; when the hand switch 3 moves in the opposite direction to the first direction, the pressing element 2 is released; it can be understood that the pressing position refers to the position where the pressing element 2 presses the workpiece 6 in the vertical direction.

[0052] The elastic element 4 is disposed at the upper end of the pressing element, and applies a spring force toward the pressing device to the pressing element 2. When the manual switch 3 releases the pressing element 2, it is used to lower the pressing element 2 to press the workpiece 6.

[0053] This utility model discloses a manually controlled positioning fixture, which integrates a pressure element 2, a manual switch 3, and an elastic element 4 on the fixture body 1. When the manual switch 3 operates in the first direction, it presses the upper side of the inner wall of the drive hole 21. Due to the upward force of the manual switch 3, the pressure element 2 begins to move upward, moving away from the pressure position of the workpiece 6. The elastic element 4 is compressed by the pressure element 2, allowing the next workpiece 6 to be replaced. When the manual switch 3 operates in the opposite direction, it releases the pressure element 2. At this time, the elastic element 4 is released, driving the pressure element 2 to press the workpiece 6 and providing a positioning and clamping force for the workpiece 6.

[0054] The manually controlled positioning fixture has a simple overall structure and occupies little space. The positioning clamping force of the workpiece 6 is provided by the elastic element 4, avoiding problems such as damage to the workpiece caused by rigid clamping. Furthermore, the opening of the positioning fixture is directly controlled by pressing the manual control switch 3, which is convenient, simple, and efficient. The clamping element 4 in the open position is also relatively stable thanks to the support of the manual control switch 3.

[0055] It is understandable that the pressure element 2 can be installed on the fixture body 1 by setting a slot structure, or the pressure element can be installed on the fixture body 1 by setting a connector. Choosing either installation method will not affect the adjustment and replacement of the pressure element 2 to adapt to the workpiece.

[0056] It is understandable that the pressure element 2 can be replaced according to the structural dimensions of the workpiece; and the contact position between the pressure element 2 and the workpiece can be adapted and adjusted according to the structure of the workpiece, such as setting a flat surface or a concave-convex surface.

[0057] It is understandable that the pressure element 2 can be selected to cooperate with the structure on the fixture body 1 to press the workpiece, or it can be selected to cooperate with other devices or components outside the fixture body 1 to press the workpiece.

[0058] It is understandable that the hand switch 3 may include structures such as cylindrical rods or square rods to lift the pressure element 2.

[0059] Specifically, such as Figure 4 As shown, the hand switch 3 includes a cylindrical receiving section 31 and a working section 32 connected thereto. The diameter of the working section 32 is larger than the diameter of the receiving section 31, and the two are transitioned by an inclined surface or a curved surface. The hand switch 3 is also provided with a gripping component 34 for easy hand holding, and a mounting section 33 connected to the working section 32 for mounting and fixing the gripping component 34. The end of the drive hole 21 near the mounting hole 11 is configured as a tapered flared opening with a gradually increasing diameter from the inside out, to facilitate the insertion of the hand switch 3.

[0060] like Figures 9a-9cWhen the hand switch 3 is in the non-working position, the left part of the receiving section 31 is located outside the fixture body 1, the middle part is located inside the drive hole 21, and the right part is located inside the mounting hole 11. The transition slope between the working section 32 and the receiving section 31 is located inside the mounting hole 11. The left part of the working section 32 is located inside the mounting hole 11, and the right part is located outside the fixture body 1.

[0061] When it is necessary to replace the workpiece after processing and inspection are completed, the hand-operated push of the gripping component 34 will cause the hand switch 3 to move horizontally in one direction ( Figure 8c , Figure 9c Moving from the center to the left, the transition slope between the working section 32 and the receiving section 31 first contacts the conical flared opening of the driving hole 21, and gradually pushes the pressure element 2 upward until the transition slope passes through the conical flared opening. Then, the working section 32 of the hand switch 3 supports the upper cylindrical surface of the inner wall of the driving hole 21, and the pressure element 2 rises to its highest point. At this time, the elastic element 4 is compressed, and the pressure element 2 releases the workpiece 6 (see...). Figures 9a-9c ).

[0062] When workpiece 6 needs to be clamped and positioned, pull the gripping part 34, and the hand switch 3 will move horizontally in the opposite direction to the above direction. Figures 8a-8c , Figures 9a-9c As the switch moves from the center to the right, the working section 32 of the hand switch 3 and the transition slope between the working section 32 and the receiving section 31 gradually move out of the drive hole 21. At this time, the elastic element 4 rebounds, driving the pressing element 2 to descend and press against the workpiece 6, and using the elastic force of the elastic element 4 to keep the workpiece 6 in the positioning position.

[0063] In some embodiments, such as Figures 5-6 As shown, the fixture body 1 is also provided with a mounting groove 12. The mounting groove 12 is provided on the side wall of the fixture body 1 and extends vertically downward from the top. The pressing element 2 is provided in the mounting groove 12 and slides with the mounting groove 12 in the vertical direction so that it can move up and down reliably. The mounting hole 11 communicates with the mounting groove 12.

[0064] The left side wall 121 and right side wall 122 of the mounting groove 12 are attached to both sides of the pressing element 2, together forming a guiding structure for guiding the operation of the pressing element 2.

[0065] By setting a groove structure on the fixture body 1 to install the pressure element 2, the space occupied by the component installation is greatly simplified, making the overall structure of the positioning fixture smaller. Furthermore, by using the groove structure itself as a guide structure for the pressure element 2, the mounting groove has both installation and guiding functions, avoiding the introduction of other guiding components and further optimizing the structure of the positioning fixture.

[0066] like Figures 1-2 As shown, the fixture body 1 is also provided with an assembly groove 13 for assembling the workpiece 6; the lower end face 131 of the assembly groove 13 cooperates with the pressing element 2 to press the workpiece 6; the assembly groove 13 and the mounting groove 12 are located on the same side of the fixture body 1 and are connected, and the pressing element 2 is partially located in the mounting groove 12 and partially located in the assembly groove 13.

[0067] The lower end face 131 of the assembly groove 13 and the left side wall 133 and right side wall 134 connected thereto together form a positioning structure for assisting in positioning the workpiece 6.

[0068] At least one side wall of the assembly groove 13 is provided with a clearance groove 132 for fingers to pick up the workpiece 6. Furthermore, the length of the assembly groove 13 along the vertical direction is greater than the length of the workpiece 6 along the vertical direction, so as to facilitate picking up the workpiece 6.

[0069] By setting an installation groove for accommodating the pressure element 2, an assembly groove 13 for accommodating the workpiece 6, and a clearance groove 132 for manually assembling the workpiece 6 on the fixture body, the guiding function for the pressure element 2 and the auxiliary positioning function for the workpiece 6 are realized. The overall structure is more integrated and realizes multi-dimensional practical functions, simplifies other components, effectively reduces assembly errors, and ensures operating accuracy.

[0070] In some embodiments, a pressure block 22 is provided at the lower end of the pressure element 2. The pressure block 22 is located on the side of the pressure element 2 facing the assembly groove 13. The workpiece 6 is in the shape of a ring surrounding the pressure block 22. The pressure block 22 and the pressure element 2 cooperate with the lower end face 131 of the assembly groove 13 to press the workpiece 6. Specifically, they cooperate to press the workpiece 6 on the side wall at the bottom to fix the workpiece 6.

[0071] Understandably, since workpiece 6 has a thin-walled, annular structure, it is prone to deformation under pressure. By placing the pressure block 22 inside workpiece 6 and cooperating with the lower end face 131 of workpiece 6 to press the side wall of workpiece 6, deformation of workpiece 6 due to compression can be effectively prevented. In some embodiments, workpiece 6 is the middle frame of a battery casing, which is made of stainless steel or other metal materials.

[0072] Optionally, when the pressure block 22 moves, its upper end will never contact the workpiece 6, so as to prevent the workpiece 6 from being deformed due to the pressure on the upper end of the workpiece 6 affecting the dimensional accuracy of the workpiece 6, and to facilitate the removal of the workpiece 6.

[0073] It is understood that the structure of the pressure block 22 can be adapted and adjusted while ensuring the positioning accuracy of the workpiece; the pressure block 22 can be integrally formed with the pressure element 2, or it can be separately connected to the pressure element 2 through a connector. In some embodiments, such as Figures 1-2 As shown, the pressing block 22 is provided with two outwardly protruding pressing protrusions 220, one of which has a triangular cross section and the other has a trapezoidal cross section. The two pressing protrusions 220 are spaced apart to leave space for processing the bottom edge of the workpiece 6 and to increase the pressing area of ​​the workpiece 6.

[0074] like Figures 1-4 As shown, an upper cover plate 5 is fixedly connected to the fixture body 1, a slot 23 is provided at the upper end of the pressing element 2, one end of the elastic element 4 abuts against the lower end face of the upper cover plate 5, and the other end is inserted into the slot 23 and abuts against the bottom of the slot 23.

[0075] like Figures 1-7 It is also provided with a support and fixing component 7 for supporting and fixing the fixture body 1. The support and fixing component 7 is provided with a guide groove 74 arranged in the horizontal direction. The guide groove 74 has an opening in the horizontal direction for the fixture body 1 to be inserted. The bottom of the fixture body 1 slides in the guide groove 74 to achieve a detachable connection with the support and fixing component 7.

[0076] The support and fixing assembly 7 includes a fixed base 71, a first limiting block 721 and a fixing block 73 disposed on the upper surface of the fixed base 7. The fixing block 73 and the first limiting block 721 are located on opposite sides of the thickness direction of the fixture body 1. The first limiting block 721, the fixing block 7 and the upper surface of the fixed base 71 together form the guide groove 74.

[0077] The support and fixing component 7 includes a second limiting block 722. The first limiting block 721 and the second limiting block 722 are fixed to the fixing base 71 at right angles. The two right-angled sides formed by the first limiting block 721 and the second limiting block 722 constitute the two limiting sides for positioning the fixture body 1.

[0078] The lower end of the fixture body 1 is provided with a positioning step 14, and the fixing block 73 is provided with a limiting step 731. The limiting step 731 and the fixing base 71 are located on the upper and lower sides of the positioning step 14.

[0079] The guide groove 74 is adapted to the contour of the bottom of the fixture body 1. The bottom of the fixture body 1 can be inserted into the guide groove 74 in the horizontal direction and is restrained by another limiting block 72. The degree of freedom of the fixture body 1 in the height direction is limited by the limiting step 14. In this way, the fixture body 1 can be disassembled and assembled by moving the fixture body 1 horizontally, and different specifications of fixture bodies 1 can be easily replaced, thereby improving production efficiency.

[0080] All the above-mentioned optional technical solutions can be combined in any way to form optional embodiments of this utility model. That is, any number of embodiments can be combined to meet the needs of different application scenarios. All of these are within the protection scope of this application and will not be described in detail here.

[0081] It should be noted that the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
