Referring to fig. 1, which is a schematic structural diagram of a clamp 10 according to an embodiment, for example, a clamp 10 includes a connecting seat 101 and a clamping body 102, wherein the connecting seat 101 is connected with the clamping body 102. The connection socket 101 is for mounting and fixing to the outside. The holding body 102 is used to hold an object placed in the holding body 102. For example, by providing the holding body 102 on the connecting base 101, the holding body 102 is used to hold a part to be processed or other object to be held. It can be understood that the clamped object is in a static state, and when the clamped object is a part to be machined, the part to be machined in the static state can be effectively machined. When the clamped object is the object to be clamped, the clamped object can be kept still and kept in the original static state.

Referring to fig. 2, which is a schematic structural diagram of the connecting socket 101 according to an embodiment, for example, the connecting socket 101 includes a socket body 201 and a fastening bolt 202. The seat body 201 and the fastening bolt 202 on the existing market are sold separately, and need to be purchased again when the seat body 201 is installed to an external object, however, the fastening bolt 202 has various models, and can be easily purchased and unmatched. For improving the installation efficiency, for example, the fastening bolt 202 is embedded in the base 201, so that the base 201 itself carries the fastening bolt 202, and there is no need to arrange the fastening bolt for the base 201 in a matching manner, which is very convenient when installing the base 201 to an external object, and is beneficial to improving the installation efficiency of the base 201.

For convenience of disposing the clamping body 102, the base body 201 is a rectangular parallelepiped structure, for example. For example, the base 201 has a mounting surface 203 and a connecting surface (not shown) opposite to each other, for example, the base 201 is provided with a mounting groove 204 on the mounting surface 203, for example, the mounting groove 204 is provided in a central region of the mounting surface 203. For example, the center area of the mounting surface is the center of the mounting surface and the area around the mounting surface, for example, the mounting surface is an axisymmetric figure and has two symmetry axes, and the center of the mounting surface is the intersection point of the two symmetry axes; in another example, the mounting surface is a centrosymmetric pattern. The area around the center of the mounting surface includes an area having a shape similar to the pattern of the mounting surface, for example, an area of 10% to 70% of the area of the mounting surface, for example, the center of the center area of the mounting surface coincides with the center of the mounting surface, and/or the area of the center area of the mounting surface is 20% to 60%, for example, 50% of the area of the mounting surface. For example, the mounting surface has a rectangular configuration, the center of the central region of the rectangular configuration of the mounting surface coincides with the center of the rectangular configuration of the mounting surface, and the area of the central region of the rectangular configuration of the mounting surface is 20% to 50%, for example 40%, of the area of the rectangular configuration of the mounting surface. The other central regions and so on. For example, the clamping body 102 is disposed on the mounting groove 204. The mounting groove 204 is a positioning area for disposing the clamping body 102, which may also be referred to as a coordinate, and provides an area for disposing the clamping body 102, so that the clamping body 102 can be conveniently disposed on the base 201 to achieve the clamping function. For example, the base 201 is provided with a mounting groove 204, that is, the mounting groove penetrates through the entire base, including the penetrating mounting surface and the connecting surface, and the portion of the base between the two surfaces, so as to form a through groove for connecting the connecting socket 101.

To facilitate the installation of the fastening bolt 202, for example, the seat body 201 is provided with an installation opening 205 penetrating through the installation surface 203 and the connection surface, i.e., the seat body 201 is provided with an installation opening 205 penetrating through the entire seat body, including the installation surface and the connection surface, and a portion of the seat body between the two surfaces to form a through opening for penetrating the fastening bolt; for example, the mounting opening 205 is adjacent to the mounting slot 204. In order to make the base 201 more stable and firm when connected externally, in the present embodiment, the number of the mounting holes 205 is four, correspondingly, the number of the fastening bolts 202 is four, and each fastening bolt 202 is correspondingly disposed at one mounting hole 205. For example, four mounting openings 205 are evenly distributed adjacent to the mounting slot 204. So, through four fastening bolt 202 for the atress of pedestal 201 is even, and is more stable firm when externally installing pedestal 201.

To restrain the fastening bolt 202 to the seat 201, for example, the fastening bolt 202 includes a bolt 206 and a stopper 207. For example, the bolt 206 is inserted through the mounting opening 205. For example, the bolt 206 has a threaded shank 208 and a shank cap 209 disposed at a fixed end of the threaded shank 208. For example, the limit block 207 is movably disposed on the threaded rod 208 away from the rod cap 209, the rod cap 209 is located on the side of the mounting surface 203, and the limit block 207 is located on the side of the connecting surface. For example, the outer diameter of the stop block 207 is greater than the inner diameter of the mounting opening 205 to prevent the stop block 207 from passing through the mounting opening 205. For example, the distance between the limiting block 207 and the rod cap 209 is greater than the distance between the mounting surface 203 and the connecting surface, so that a movable space is formed between the threaded rod body 208 and the base body 201, and because the limiting block 207 is movably arranged on the threaded rod body 208 away from the rod cap 209, the limiting block 207 does not affect the screwing function of the threaded rod body 208, and the fastening bolt 202 is limited on the base body 201.

Referring to fig. 3, which is a schematic structural diagram of the clamping body 102 in an embodiment, for example, the clamping body 102 includes a functional component 301 and a clamping component 302, the clamping component 302 is connected to the functional component 301, and the functional component 301 is configured to drive the clamping component 302 to operate so as to clamp an object placed in a clamping space 303 of the clamping component 302. In an embodiment, the shape structure of the mounting groove 204 is matched with the shape structure of the functional element 301, in combination with fig. 2 and 3. For example, the functional piece 301 is snapped into the mounting groove 204 and the functional piece 301 is restrained in the mounting groove 204 by providing a screw in the mounting groove 204.

Referring to fig. 4, which is a schematic cross-sectional view of the clamping body 102 according to an embodiment, for example, the functional element 301 includes a housing 401 and a functional component 402, and the housing 401 is inserted into the mounting groove 204. For example, the shape and structure of the mounting groove 204 are matched with the shape and structure of the housing 401, for example, the housing 401 is tightly matched with the mounting groove 204; as another example, the housing 401 is in an interference fit with the mounting groove 204. For example, the functional component 402 is disposed in the housing 401. For example, the functional module 402 includes a telescopic mechanism 403, a fixed terminal 404 and a free terminal 405, the telescopic mechanism 403 and the fixed terminal 404 are respectively connected to the housing 401, and the free terminal 405 is disposed on the telescopic end of the telescopic mechanism 403. The retractable mechanism 403 is configured to drive the free terminal 405 to move toward the fixed terminal 404 during operation, that is, the retractable mechanism 403 drives the free terminal 405 to move along the X direction when being stressed and drives the free terminal 405 to move in the opposite direction of the X direction when not being stressed, which can also be understood as that the retractable mechanism 403 drives the free terminal 405 to reciprocate in the X direction when being retracted.

In this embodiment, the telescoping mechanism is an electric push rod, i.e., a linear actuator. It should be noted that the electric push rod can be regarded as an extension of the rotary motor in terms of structure. For example, the electric push rod is a linear actuator consisting of a motor push rod and a control device mechanism. In another example, the telescoping mechanism is a linear stepper motor. It should be noted that linear stepping motor, also called linear stepping motor, is a magnetic rotor core that rotates by interaction with a pulse electromagnetic field generated by a stator, and converts a rotary motion into a linear motion inside the motor. For example, the telescopic mechanism takes electricity by a power line which is externally connected with a power supply; in another example, the telescopic mechanism is powered by a battery, so that power-on work is realized.

In order to enable the clamping member 302 to clamp an external object, for example, the clamping member 302 includes a fixed clamping member 406 and a free clamping member 407, for example, the fixed clamping member 406 is connected to the fixed terminal 404, the free clamping member 407 is connected to the free terminal 405, the telescoping mechanism 403 operates to move the free clamping member 407 toward the fixed clamping member 406, that is, the telescoping mechanism 403 operates to move the free clamping member 407 along the direction X, so that an object placed in the clamping space 303 of the clamping member 302 can be clamped when the free clamping member 407 moves toward the fixed clamping member 406.

In the fixture 10, the clamping body 102 is arranged on the connecting seat 101, and the to-be-processed component is clamped by the clamping body 102, on one hand, the connecting seat 101 comprises the seat body 201 and the fastening bolt 202, so that the fastening bolt 202 is not required to be additionally arranged during assembly, the seat body 201 is provided with the mounting surface 203 and the connecting surface which are opposite, the rod cap 209 is positioned on one side of the mounting surface 203, the limiting block 207 is positioned on one side of the connecting surface, and the outer diameter of the limiting block 207 is larger than the inner diameter of the mounting opening 205, so that the fastening bolt 202 is not dropped off; on the other hand, by driving the free clamping piece 407 to move toward the direction of the fixed clamping piece 406 when the telescopic mechanism 403 works, in the process, because only the free clamping piece 407 moves, when the to-be-processed part is clamped, the to-be-processed part is tightly attached to the fixed clamping piece 406 and is statically placed, so that the gap between the fixed clamping piece 406 and the free clamping piece 407 is slowly reduced, the to-be-processed part between the fixed clamping piece 406 and the free clamping piece 407 is clamped, the clamping stability is high, and the subsequent processing operation of the to-be-processed part is facilitated.

Since the telescopic end of the telescopic mechanism 403 is only connected to the free clip member 407, the free clip member 407 inevitably deviates under the influence of friction force during the process of driving the free clip member 407 to move along the X direction when the telescopic mechanism 403 is in operation, and in order to reduce the deviation of the free clip member 407 to the maximum, as shown in fig. 4, the clamping body 102 further includes a positioning bar 410. For example, the free clip 407 has a first positioning frame 421 and a first elastic member 422. For example, the first elastic member 422 is accommodated in the first positioning frame 421, one end of the first elastic member 422 is fixed to the bottom of the first positioning frame 421, and the other end of the first elastic member 422 is connected to one end of the positioning strip 410. For example, the fixing clip 406 has a second positioning frame 431 and a second elastic member 432. One end of the second elastic member 432 is fixed to the bottom of the second positioning frame 431, and the other end of the second elastic member 432 is connected to the other end of the positioning bar 410. For example, the first elastic member 422 and the second elastic member 432 are springs. For example, the cross-sectional area of the positioning bar 410 is smaller than the cross-sectional areas of the first positioning frame 421 and the second positioning frame 431. For example, the length of the positioning bar 410 is equal to the sum of the depths of the first positioning frame 421 and the second positioning frame 431. In this way, in the process of driving the free clip 407 to move along the X direction when the telescoping mechanism 403 operates, the free clip 407 will travel along a predetermined track under the guiding action of the positioning bar 410, the first positioning frame 421 and the second positioning frame 431, and meanwhile, under the elastic action of the first elastic member 422 and the second elastic member 432, when the telescoping mechanism 403 stops operating, the free clip 407 will return to the original position along the opposite direction of the X direction, thereby reducing the deviation of the free clip 407 to the maximum.

For example, the free clamping member 407 and the fixed clamping member 406 have teeth 440 on opposite sides thereof for improving the clamping effect. For example, teeth 440 have a right triangle configuration. Further, in order to make the clamp of the present embodiment suitable for clamping a cylinder or a cylinder-like body with a predetermined outer diameter, for example, the free clamping member 407 has a first clamping gap 451, and the fixed clamping member 406 has a second clamping gap 452, for example, the first clamping gap 451 has a semicircular cross section, for example, the second clamping gap 452 has a semicircular cross section, for example, the first clamping gap 451 and the second clamping gap 452 form a circular second clamping space. Thus, the first clamping gap 451 and the second clamping gap 452 form a circular second clamping space, so that the clamp can be suitable for clamping a cylinder or a similar cylinder with a preset outer diameter, and the practicability of the clamp is effectively improved.

Referring to fig. 5, which is a schematic structural diagram of an embodiment of a combined clamping device, referring to fig. 1 and 5, for example, a combined clamping device 20 includes a base plate 510 and at least two clamps 10. For example, the bottom plate 510 is provided with a strip-shaped sliding groove 520 and at least two limiting clamping grooves 530 spaced from the strip-shaped sliding groove 520, and the limiting clamping grooves 530 are provided with screw holes having internal threads. For example, each fixture 10 is correspondingly disposed in a limiting slot 530, the fixture 10 includes a connecting seat 101, the connecting seat 101 includes a seat body 201, the seat body 201 has a mounting surface 203 and a connecting surface (not shown) that are opposite to each other, the connecting surface abuts against the bottom of the limiting slot 530, and the bolt is in threaded engagement with the screw hole.

For example, the bottom plate 510 has a rectangular parallelepiped structure. For example, the strip-shaped sliding groove 520 extends along the length direction of the bottom plate 510. For example, the axis of the strip chute 520 is aligned with the axis of the bottom plate 510. For example, the width of the position-limiting locking groove 530 is greater than the width of the strip-shaped sliding groove 520. For example, the screw hole is opened in the central region of the limit slot 530. For example, the center of the central region of the limiting clamping groove coincides with the center of the limiting clamping groove, and/or the area of the central region of the limiting clamping groove is 10% -60%, for example 50%, of the area of the limiting clamping groove. For example, the limiting clamping groove has a rectangular structure, the center of the central region of the rectangular structure of the limiting clamping groove coincides with the center of the rectangular structure of the limiting clamping groove, and the area of the central region of the rectangular structure of the limiting clamping groove is 20% -50%, for example 40%, of the area of the rectangular structure of the limiting clamping groove.
