[0001] This utility model relates to the field of pressing fixture technology, specifically to an adjustable pressing fixture. Background Technology

[0002] During assembly, products often need to be pressed together. Manual pressing by operators can lead to inaccurate positioning and excessive or insufficient pressing force, significantly reducing efficiency. This wastes costs and increases labor costs, so pressing fixtures are often used. However, the pressing height of existing pressing fixtures is usually difficult to adjust quickly. To change the pressing height to accommodate different sized products, the entire fixture needs to be disassembled and reassembled, impacting work efficiency. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an adjustable pressing fixture to solve the problem mentioned in the background art that the pressing height is usually difficult to adjust quickly to adapt to target presses of different sizes.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is an adjustable pressing fixture, comprising:

[0005] The base plate extends along the first direction, with the top for placing the target compressible.

[0006] A support column extends along a second direction and is located on top of the base plate.

[0007] The driving pressing end is located on one side of the support column along the first direction, and is used to move downward relative to the base plate along the second direction to press the target compressible.

[0008] An adjustment module, disposed along the first direction between the support column and the driving pressing end, includes a fixed frame, a transition connector, and a turntable. The fixed frame includes a threaded rod extending along the second direction, with its bottom rotatably connected to the fixed frame. One end of the transition connector along the first direction is sleeved on and threadedly connected to the threaded rod, and the other end is connected to the driving pressing end. The turntable is disposed above the fixed frame and fixedly connected to the top of the threaded rod. It is used to adjust the distance between the driving pressing end and the base plate by rotating the turntable and the threaded rod, thereby moving the transition connector along the second direction relative to the base plate. The first direction is perpendicular to the second direction.

[0009] This utility model provides a method of adjusting the height of the transition connector by rotating the turntable, thereby adjusting the distance between the driving pressing end and the base plate, and adapting to target presses of different sizes by setting an adjustment module and using a threaded rod and a threaded connection between the threaded rod and the transition connector.

[0010] In some embodiments, the fixing frame further includes a guide rod extending along the second direction and respectively disposed on both sides of the threaded rod along the third direction. One end of the transition connector along the first direction is sleeved on the guide rod, and the first direction, the second direction, and the third direction are perpendicular to each other.

[0011] By adopting the above technical solution, the guide rod helps to enhance the stability of the transition connector during movement. Especially when performing precise pressing operations, it can reduce the deviation caused by improper operation or external force, thereby improving the processing quality of the product.

[0012] In some embodiments, the adjustment module further includes a clamping assembly comprising a U-shaped clamp, a screw, and a handle. The U-shaped clamp extends along the first direction and is disposed between the fixed frame and the turntable. The threaded rod is disposed within a groove in the U-shaped clamp. The screw extends along a third direction and is disposed at the unconnected end of the U-shaped clamp along the first direction, and is threadedly connected to the unconnected end. The handle is disposed on the side of the screw along the third direction away from the U-shaped clamp, for rotating the handle to clamp or release the threaded rod by the U-shaped clamp.

[0013] Using the above technical solution, a threaded connection between the screw and the U-shaped clamping block is employed. The screwing depth of the screw and the clamping tightness of the U-shaped clamping block can be quickly adjusted by rotating the handle. After adjusting the drive pressing end to the required height by rotating the turntable, rotating the handle increases the screwing depth of the screw, thereby clamping and fixing the threaded rod to prevent displacement.

[0014] In some embodiments, the adjustment module further includes a connecting plate extending along the first direction, one end of which is connected to the fixed frame, and the other end is rotatably connected to the top of the support column. Fixed bearings are provided on both the upper and lower sides of the connection between the connecting plate and the support column, and the fixed bearings are sleeved on the support column.

[0015] By employing the above technical solution, and by providing fixed bearings on both the upper and lower sides of the connection between the connecting plate and the support column, the stability of the entire adjustment module can be improved, displacement caused by external forces or vibrations can be reduced, thereby ensuring the accuracy of the pressing process. Furthermore, the relative position of the driving pressing end can be changed by rotating the connecting plate relative to the support column.

[0016] In some embodiments, the drive pressing end includes a fixed bearing housing, a rotating assembly, and a lifting rod. The fixed bearing housing is connected to the transition connector and has a through hole extending along the second direction. The rotating assembly includes a connecting piece and a limiting piece. The connecting piece extends along the second direction and is respectively disposed on both sides of the fixed bearing housing along a third direction. The limiting piece extends along the third direction, with both ends connected to the limiting piece, and is disposed on one side of the connecting piece along the third direction. The lifting rod extends along the second direction and passes through the through hole.

[0017] By adopting the above technical solution, the fixed bearing housing can make the up-and-down movement of the lifting rod more precise, which is beneficial to improving the pressing accuracy.

[0018] In some embodiments, the rotating assembly further includes a handle and a plurality of rotating pins. The handle includes a grip portion and an adapter portion, with the grip portion positioned away from the connecting piece. The adapter portion is L-shaped and symmetrically arranged on both sides of the top of the lifting rod along the third direction. One end of the adapter portion is connected to the lifting rod, the other end is connected to the grip portion, and the corner is connected to the top of the connecting piece. The plurality of rotating pins are respectively located at the connection points between the connecting piece and the fixed bearing seat, the adapter portion, the adapter portion and the lifting rod, and the grip portion, for rotating the grip portion to drive the lifting rod to move up and down relative to the fixed bearing seat along the second direction.

[0019] In some embodiments, the drive pressing end further includes a sleeve and a lower pressing block. The sleeve extends along the second direction and is rotatably connected to the bottom of the lifting rod. The lower pressing block extends along the third direction and is disposed at the bottom of the sleeve, for moving the lower pressing block via the lifting rod to press.

[0020] Using the above technical solution, the lower pressing block is moved by the lifting rod to press the target material. At the same time, the lower pressing block can be rotated by rotating the sleeve to change the extension direction and adapt to more pressing angle requirements.

[0021] In some embodiments, the adjustable pressing fixture further includes a fixing assembly comprising a reinforcing plate, triangular side plates, and a reinforcing semicircular plate. The reinforcing plate extends along the second direction, its bottom end connecting to the base plate, and is disposed on one side of the support column along the first direction.

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0033] refer to Figures 1 to 3 , Figure 1 A perspective view of an adjustable pressing fixture 1 provided in an embodiment of the present invention is shown; Figure 2 The diagram shows a front view of an adjustable pressing fixture 1 provided in an embodiment of the present invention; Figure 3 A partial structural schematic diagram of an adjustable pressing fixture 1 provided in an embodiment of the present invention is shown.

[0034] like Figures 1 to 3 As shown, the technical solution adopted by this utility model is an adjustable pressing fixture 1, including a base plate 2, a support column 20, a driving pressing end, and an adjusting module 3, wherein the base plate 2 is along a first direction ( Figure 1 Extending in the X direction (as shown), the top is used to place the target compressible. The support column 20 extends along the second direction (as shown in the X direction). Figure 1 Extending in the Z direction (as shown), and located on the top of the base plate 2. The driving pressing end is located on one side of the support column 20 along the first direction, and is used to move downward relative to the base plate 2 in the second direction to press the target compressible.

[0035] The adjustment module 3 is positioned between the support column 20 and the drive pressing end along a first direction. It includes a fixed frame 30, a transition connector 31, and a turntable 32. The fixed frame 30 includes a threaded rod 300 extending along a second direction, with its bottom rotatably connected to the fixed frame 30. One end of the transition connector 31 along the first direction is fitted onto and threadedly connected to the threaded rod 300, while the other end is connected to the drive pressing end. The turntable 32 is positioned above the fixed frame 30 and fixedly connected to the top of the threaded rod 300. Rotating the turntable 32 and the threaded rod 300 causes the transition connector 31 to move relative to the base plate 2 along the second direction, thereby adjusting the distance between the drive pressing end and the base plate 2. The first direction is perpendicular to the second direction.

[0036] The adjustable pressing fixture 1 provided in this application can change the height of the transition connector 31 by setting an adjustment module 3 and using a threaded rod 300 to be threadedly connected to the transition connector 31. This allows for adjustment of the distance between the driving pressing end and the base plate 2, thus adapting to target presses of different sizes.

[0037] In some embodiments, reference Figures 1 to 3 The fixed frame 30 also includes guide rods 301, which extend along the second direction and are respectively disposed on the threaded rods 300 along the third direction. Figure 1On both sides (as shown in the Y direction), the transition connector 31 is sleeved on the guide rod 301 at one end along the first direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0038] For example, the guide rod 301 helps to enhance the stability of the transition connector 31 during movement, especially during precise pressing operations, and can reduce deviations caused by improper operation or external forces, thereby improving the processing quality of the product.

[0039] In some embodiments, reference Figures 1 to 3 The adjustment module 3 also includes a clamping assembly, which includes a U-shaped clamp 40, a screw 41, and a handle 42. The U-shaped clamp 40 extends along a first direction and is located between the fixed frame 30 and the turntable 32. The threaded rod 300 is located in the groove of the U-shaped clamp 40. The screw 41 extends along a third direction and is located at the unconnected end of the U-shaped clamp 40 along the first direction, and is threadedly connected to the unconnected end. The handle 42 is located on the side of the screw 41 away from the U-shaped clamp 40 along the third direction, and is used to clamp or release the threaded rod 300 by rotating the handle 42.

[0040] For example, by using a threaded connection between the screw 41 and the U-shaped clamp 40, the screwing degree of the screw 41 and the clamping degree of the U-shaped clamp 40 can be quickly adjusted by rotating the handle 42. After adjusting the drive pressing end to the required height by rotating the turntable 32, rotating the handle 42 increases the screwing degree of the screw 41, thereby clamping and fixing the threaded rod 300 to prevent displacement.

[0041] In some embodiments, reference Figures 1 to 3 The adjustment module 3 also includes a connecting plate 33, which extends along the first direction, with one end connected to the fixed frame 30 and the other end rotatably connected to the top of the support column 20. Fixed bearings 34 are provided on both the upper and lower sides of the connection between the connecting plate 33 and the support column 20, and the fixed bearings 34 are sleeved on the support column 20.

[0042] For example, by providing fixed bearings 34 on both the upper and lower sides of the connection between the connecting plate 33 and the support column 20, this design can improve the stability of the entire adjustment module 3, reduce displacement caused by external forces or vibrations, and thus ensure the accuracy of the pressing process. In addition, the relative position of the driving pressing end can be changed by rotating the connecting plate 33 relative to the support column 20.

[0043] In some embodiments, reference Figures 1 to 3The driving pressing end includes a fixed bearing seat 50, a rotating assembly 6, and a lifting rod 51. The fixed bearing seat 50 is connected to the transition connector 31 and has a through hole extending in a second direction. The rotating assembly 6 includes a connecting piece 60 and a limiting piece 61. The connecting piece 60 extends in the second direction and is respectively disposed on both sides of the fixed bearing seat 50 in a third direction. The limiting piece 61 extends in the third direction, with both ends connected to the limiting piece 61 and disposed on one side of the connecting piece 60 in the third direction. The lifting rod 51 extends in the second direction and passes through the through hole.

[0044] For example, the fixed bearing housing 50 can make the up-and-down movement of the lifting rod 51 more precise, which is beneficial to improving the pressing accuracy.

[0045] In some embodiments, reference Figures 1 to 3 The rotating assembly 6 also includes a handle 63 and multiple rotating pins 62. The handle 63 includes a hand-held portion 630 and an adapter portion 631, with the hand-held portion 630 positioned away from the connecting piece 60. The adapter portion 631 is L-shaped and symmetrically positioned on both sides of the top of the lifting rod 51 along a third direction. One end of the adapter portion 631 is connected to the lifting rod 51, and the other end is connected to the hand-held portion 630. The corner is connected to the top of the connecting piece 60. Multiple rotating pins 62 are respectively located at the connection points between the connecting piece 60 and the fixed bearing seat 50, the adapter portion, the adapter portion and the lifting rod 51, and the hand-held portion 630, for rotating the hand-held portion 630 to drive the lifting rod 51 to move up and down relative to the fixed bearing seat 50 along a second direction.

[0046] For example, Figure 1 and Figure 2 The adjustable pressing fixture 1 is in a downward pressing state. Due to the rotational connection between the adapter 631 and the connecting piece 60, the handle 63 can no longer press down, and the lifting rod 51 moves to the bottom, driving the pressing end to press the target material. As the handle 63 flips upward, the lifting rod 51 moves upward. When the handle 63 moves to the leftmost end, due to the rotational connection between the adapter 631 and the connecting piece 60, the handle 63 can no longer move, and the lifting rod 51 moves to the highest position.

[0047] In some embodiments, reference Figures 1 to 3 The driving pressing end also includes a sleeve 52 and a lower pressing block 53. The sleeve 52 extends along a second direction and is rotatably connected to the bottom of the lifting rod 51. The lower pressing block 53 extends along a third direction and is located at the bottom of the sleeve 52, and is used to move the lower pressing block 53 to press by the lifting rod 51.

[0048] For example, the lower pressure block 53 is moved by the lifting rod 51 to press the target material. At the same time, the lower pressure block 53 can be rotated by the rotating sleeve 52 to change the extension direction to adapt to more pressing angle requirements.

[0049] In some embodiments, reference Figures 1 to 3 The adjustable pressing fixture 1 also includes a fixing assembly, which includes a reinforcing plate 70, a triangular side plate 71, and a reinforcing semicircular plate 72. The reinforcing plate 70 extends along a second direction, its bottom end is connected to the base plate 2, and it is located on one side of the support column 20 along a first direction. The triangular side plate 71 is located on both sides of the support column 20 along a third direction and is connected to the reinforcing plate 70 and the base plate 2. The reinforcing semicircular plate 72 extends along the first direction, one end of which is connected to the top of the reinforcing plate 70, and the other end is fitted onto the support column 20.

[0050] For example, the design of the reinforcing plate 70, the triangular side plate 71 and the reinforcing semi-circular plate 72 provides auxiliary support for the support column 20, making the structure of the entire fixing assembly more stable so as to withstand the pressure and weight of the drive pressing end and the adjustment module 3.

[0051] In some embodiments, reference Figures 1 to 3 The fixing assembly includes multiple ribs 73 and fixing seats 74. The multiple ribs 73 are respectively located on the upper and lower sides of the connecting plate 33 and connected to the fixing frame 30. The fixing seats 74 are sleeved on the bottom of the support column 20 and bolted to the base plate 2 for fixation.

[0052] For example, by providing multiple ribs 73 at the connection between the connecting plate 33 and the fixed frame 30, the stability and rigidity of the connection structure can be enhanced, improving the reliability of the adjustable pressing fixture 1. The fixing seat 74 can strengthen the connection between the support column 20 and the base plate 2, ensuring the stability and safety of the support column 20 during use.

[0053] In some embodiments, reference Figures 1 to 3 The top of the turntable 32 is provided with a handle 320, which extends along the second direction.

[0054] For example, the design of the handle 320 allows the operator to directly and manually rotate the turntable 32 for quick adjustment and positioning, improving the convenience of operation.

[0055] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
