Description

Technical Field

[0001] This utility model belongs to the field of clamping equipment technology, specifically relating to a dual-position clamping adapter. Background Technology

[0002] Clamping devices are crucial equipment used in the manufacturing process to fix workpieces or tools, ensuring their stable position during machining, assembly, and inspection. Their core function is to apply external force to counteract cutting forces, vibrations, and other interferences during machining or operation, thereby ensuring process accuracy and operational safety. When designing the structure of a clamping device, its simplicity and adaptability must be considered, especially for rod-shaped workpieces. Current technology often uses ring-shaped clamping blocks for clamping, but the clamping range is generally only 3mm, and the clamping effect is poor for irregularly shaped rods.

[0003] Therefore, it is necessary to design a clamping device that is well-suited for rod-shaped workpieces. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a dual-position clamping adapter with good adaptability and simple operation.

[0005] This utility model provides a dual-position clamping adapter, including a first clamping part and a second clamping part, wherein the first clamping part and the second clamping part are connected by a connecting rod and are respectively disposed at both ends of the connecting rod;

[0006] The first clamping part includes a rotary clamping member, the rotary clamping member forming a first clamping cavity in the middle, the first clamping cavity opening outward for clamping the workpiece;

[0007] The second clamping part includes a first clamping block and a second clamping block disposed opposite to each other. The first clamping block is fixedly connected to the connecting rod, and the second clamping block is movably connected to the first clamping block through an adjusting member. A second clamping cavity is formed between the first clamping block and the second clamping block. The adjusting member is used to adjust the size of the second clamping cavity to clamp the workpiece.

[0008] Preferably, the rotary clamping member includes a plurality of elastic plates and a rotary nut disposed at the upper end. The elastic plates are spaced apart on the upper end, and the rotary nut is sleeved on the elastic plates and movably connected to the outer wall of the rotary clamping member. When the rotary nut moves inward, the rotary nut abuts against the elastic plates and moves the elastic plates toward the axis of the first clamping cavity to clamp the workpiece. When the rotary nut moves outward, the elastic plates move away from the axis of the first clamping cavity to release the workpiece.

[0009] Preferably, the inner wall of the torsion nut is provided with a threaded section, a cavity section, and an abutment section in sequence. The inner surface of the threaded section is provided with an internal thread, and the outer wall of the torsion clamp is provided with a corresponding external thread for movably connecting with the torsion clamp.

[0010] The threaded section and the abutting section protrude toward the axial direction relative to the cavity section, so that the cavity section forms a clearance cavity.

[0011] Preferably, the abutting section is configured as an inclined surface extending from the outer end of the abutting section toward the cavity section.

[0012] Preferably, the elastic sheet includes a connecting portion and a limiting portion. The connecting portion is disposed at the lower part of the elastic sheet and is used to connect with the rotary clamping member. The limiting portion is disposed at the upper part of the elastic sheet and protrudes toward the abutting section. When the limiting portion abuts against the abutting section, the elastic sheet deforms toward the axis of the first clamping cavity.

[0013] Preferably, the side of the limiting portion facing the abutting section is configured as an inclined surface corresponding to the abutting section, and the inclined surface is inclined from the outer end of the elastic sheet toward the abutting section.

[0014] Preferably, the lower end of the rotary clamping member is fixedly connected to the connecting rod, and the lower part of the rotary clamping member has an observation port that extends through the first clamping cavity for observing the depth of the workpiece in the first clamping cavity.

[0015] Preferably, the first clamping block has a first groove recessed in the middle relative to the second clamping block, and the second clamping block has a second groove recessed in the middle relative to the first clamping block. The first groove and the second groove are positioned to form the second clamping cavity for clamping the workpiece.

[0016] Preferably, the first clamping block and the second clamping block further include a plurality of adjusting portions extending outward relative to the second clamping cavity. The adjusting portions are provided with connecting holes, and the connecting holes on the first clamping block and the second clamping block correspond to each other. The adjusting member passes through the connecting holes of the first clamping block and the second clamping block in sequence to connect the first clamping block and the second clamping block. The adjusting member can be adjusted to loosen / tighten to adjust the distance between the first clamping block and the second clamping block.

[0017] Compared to existing technologies, the dual-position clamping adapter of this solution has at least the following advantages:

Detailed Implementation

[0027] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0028] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0029] This utility model embodiment provides a dual-position clamping adapter 1, including a first clamping part 10 and a second clamping part 20. The first clamping part 10 and the second clamping part 20 are connected by a connecting rod 30 and are respectively disposed at both ends of the connecting rod 30. It can be understood that the connecting rod 30 used to connect the first clamping part 10 and the second clamping part 20 can be designed into different shapes as needed, such as a straight rod or a curved rod forming an angle. The two ends of the first clamping part 10 and the second clamping part 20 can be fixedly connected.

[0030] The first clamping part 10 includes a rotary clamping member 101, and a first clamping cavity 102 is formed in the middle of the rotary clamping member 101. The first clamping cavity 102 is open to the outside and is used to clamp the workpiece. It can be understood that the "outer side" mentioned here refers to the side away from the connecting rod 30. The workpiece is inserted from the open port of the first clamping cavity 102, and the tightness of the workpiece clamping can be adjusted by adjusting the tightness of the rotary clamping member 101.

[0031] The second clamping part 20 includes a first clamping block 201 and a second clamping block 202 arranged opposite to each other. The first clamping block 201 is fixedly connected to the connecting rod 30, and the second clamping block 202 is movably connected to the first clamping block 201 through an adjusting member 203. A second clamping cavity 203 is formed between the first clamping block 201 and the second clamping block 202. The adjusting member 203 is used to adjust the size of the second clamping cavity 203 to clamp the workpiece. It can be understood that the first clamping block 201 and the second clamping block 202 are arranged opposite to each other, and the second clamping cavity 203 is opened between the first clamping block 201 and the second clamping block 202. The adjusting member 203 can be a bolt and nut, or a four-corner hand screw, a slotted hand screw, etc., to facilitate the user to quickly adjust the tightness of the second clamping cavity 203.

[0032] In this embodiment, the rotary clamping member 101 includes a plurality of elastic plates 103 disposed at the upper end and a rotary nut 104. The elastic plates 103 are spaced apart on the upper end, and the rotary nut 104 is sleeved on the elastic plates 103 and movably connected to the outer wall of the rotary clamping member 101. When the rotary nut 104 moves inward, it abuts against the elastic plates 103 and moves the elastic plates 103 toward the axis of the first clamping cavity 102 to clamp the workpiece. When the rotary nut 104 moves outward, the elastic plates 103 move away from the axis of the first clamping cavity 102 to release the workpiece. It can be understood that the elastic plates 103 are vertically connected to the end of the rotary clamping member 101 and are spaced apart along the periphery of the first clamping cavity 102. When multiple elastic plates 103 clamp the workpiece together, the workpiece is subjected to uniform force at the clamping point, avoiding excessive clamping force that could deform the workpiece. The axial direction of the first clamping cavity 102 mentioned here refers to the cylindrical cavity formed by the first clamping cavity 102, and the axis is the axis of the cylinder. The inward movement of the torsion nut 104 refers to its movement towards the connecting rod 30, and the outward movement refers to its movement away from the connecting rod 30. When the torsion nut 104 moves inward, the inner wall of the torsion nut 104 generates a clamping force on the multiple elastic plates 103 in the axial direction of the first clamping cavity 102, causing the multiple elastic plates 103 to press together in the axial direction of the first clamping cavity 102, thus clamping the workpiece. Adjusting the elastic plates 103 by torsion nut 104 is a simple adjustment method, allowing operators to quickly clamp the workpiece.

[0033] In this embodiment, the inner wall of the torsion nut 104 is sequentially provided with a threaded section 105, a cavity section 106, and an abutment section 107. The inner surface of the threaded section 105 is provided with an internal thread, and the outer wall of the torsion clamp 101 is provided with a corresponding external thread for movably connecting with the torsion clamp 101.

[0034] The threaded section 105 and the abutting section 107 protrude towards the axis relative to the cavity section 106, so that the cavity section 106 forms a clearance cavity 108. It can be understood that when the torsion nut 104 is in a loose state, the upper end of the elastic piece 103 can be accommodated in the clearance cavity 108, and the threaded section 105 protrudes relative to the cavity section 106, which can ensure that the torsion nut 104 can be locked on the torsion holder and will not easily fall off.

[0035] In this embodiment, the abutment section 107 is configured as an inclined surface from the outer end of the abutment section 107 toward the cavity section 106. It can be understood that the inclined surface of the abutment section 107 is inclined toward the axis of the first clamping cavity 102. When the toggle nut 104 moves inward, the elastic piece 103 is gradually squeezed by the abutment section 107, thereby increasing the clamping force and adjusting the diameter of the first clamping end to adapt to the size of the workpiece, resulting in better adaptability.

[0036] In this embodiment, the elastic sheet 103 includes a connecting portion 109 and a limiting portion 110. The connecting portion 109 is disposed at the lower part of the elastic sheet 103 for connection with the rotary clamping member 101. The limiting portion 110 is disposed at the upper part of the elastic sheet 103 and protrudes towards the abutment section 107. When the limiting portion 110 abuts against the abutment section 107, the elastic sheet 103 deforms towards the axis of the first clamping cavity 102. It can be understood that the limiting portion 110 protrudes towards the abutment section 107, and when the protruding limiting portion 110 contacts the abutment section 107, it allows the elastic sheet 103 to have a larger range of elastic deformation, thereby increasing the adaptability of clamping and providing greater clamping force.

[0037] In a further embodiment, the side of the limiting part 110 facing the abutting section 107 is provided as an inclined surface corresponding to the abutting section 107. The inclined surface is inclined from the outer end of the elastic sheet 103 toward the abutting section 107. It can be understood that the inclined surface of the limiting part 110 and the inclined surface of the abutting section 107 are in opposite inclination directions, so that when the limiting part 110 and the abutting section 107 are in contact, the squeezing force is more uniform and the movement is smoother, making the rotary clamping member 101 more labor-saving.

[0038] In this embodiment, the lower end of the rotary clamping member 101 is fixedly connected to the connecting rod 30. The lower part of the rotary clamping member 101 has an observation port 111 that extends to the first clamping cavity 102 for observing the depth of the workpiece in the first clamping cavity 102. It can be understood that the rod-shaped workpiece is inserted into the first clamping cavity 102, and the rotary clamping member 101 applies a clamping force to hold and fix the workpiece. For workpieces with uneven shapes or rod diameters, it is necessary to ensure that the insertion depth of the workpiece is sufficient to ensure that the workpiece is not easily loosened after clamping and fixing. For workpieces that cannot reach the insertion depth, the first clamping part 10 is not used to ensure safety during the processing.

[0039] In this embodiment, the first clamping block 201 has a first groove 204 recessed in the middle relative to the second clamping block 202, and the second clamping block 202 has a second groove 205 recessed in the middle relative to the first clamping block 201. The first groove 204 and the second groove 205 are positioned correspondingly to form a second clamping cavity 203 for clamping the workpiece. For example, the first groove 204 and the second groove 205 can be configured as V-shaped grooves or as arc-shaped grooves. The depth of the grooves can be adjusted according to the overall size of the dual-position clamping adapter 1; that is, a larger adapter will have a deeper groove, and a smaller adapter will have a shallower groove, to accommodate workpieces of different sizes.

[0040] In this embodiment, the first clamping block 201 and the second clamping block 202 also include a plurality of adjusting portions 206 extending outward relative to the second clamping cavity 203. Each adjusting portion 206 has a connecting hole 207, which corresponds to the connecting holes 207 on the first clamping block 201 and the second clamping block 202. An adjusting member 203 passes sequentially through the connecting holes 207 of the first clamping block 201 and the second clamping block 202 to connect them. The adjusting member 203 can be adjusted to loosen / tighten to adjust the distance between the first clamping block 201 and the second clamping block 202. The adjusting member 203 can be a screw and nut, or a hand-tightening screw, etc. Adjusting the tightness of the adjusting member 203 adjusts the distance between the first clamping block 201 and the second clamping block 202, which in turn determines the size of the second clamping cavity 203 to fix the workpiece. This design allows for rapid adjustment of the adjusting member 203 to complete the clamping operation. For example, adjustment parts 206 are provided in all four directions of the first clamping block 201 and the second clamping block 202, and the multiple adjustment parts 206 are symmetrical from left to right or front to back. In this way, when the workpiece is clamped, the clamping force is applied to the workpiece evenly, which can ensure that the workpiece is not damaged.
