The application provides a clamp which can be used for clamping a workpiece. Referring to fig. 1-2, a clamp according to an embodiment of the present application includes a frame 1, a clamping member 2, an elastic member 3, and a driving member 4. The clamping piece 2 is connected with the frame body 1, and the clamping piece 2 is used for clamping a workpiece 5, and the clamping piece 2 comprises clamping jaws 21, and at least two clamping jaws 21 are used for clamping the same side face of the workpiece 5. The driving piece 4 is connected with the frame body 1, the driving piece 4 is connected with the clamping jaw 21 through the elastic piece 3, the driving piece 4 can drive the elastic piece 3 to enable the elastic piece 3 to drive the clamping jaw 21 to clamp the workpiece 5, the driving piece 4 is further connected with the clamping jaw 21, and the driving piece 4 can drive the clamping jaw 21 to be separated from the workpiece 5.
In this embodiment, referring to fig. 1-2, the driving member 4 may be connected to the elastic member 3, where the elastic member 3 is connected to the clamping jaw 21 of the clamping member 2, when the fixture in this embodiment is used to clamp a workpiece 5, the driving member 4 may drive the elastic member 3 to move, and the elastic member 3 drives the clamping jaw 21 to approach the workpiece 5, so as to clamp the workpiece 5, so that the fixture in this embodiment forms a clamping effect on the workpiece 5, and the workpiece 5 may be kept at a certain fixed position, or the workpiece 5 may be moved smoothly. The driving member 4 may also be directly connected to the clamping jaw 21, and the driving member 4 may directly drive the clamping jaw 21 to disengage from the workpiece 5, thereby eliminating the clamping effect on the workpiece 5 and allowing the workpiece 5 to disengage from the fixture. When needs the anchor clamps centre gripping work piece of this application embodiment, driving piece 4 has the drive force to elastic component 3, simultaneously, work piece 5 forms the reaction force to clamping jaw 21, the reaction force is through clamping jaw 21 effect to elastic component 3, elastic component 3 is between driving piece 4 and clamping jaw 21, the both ends of elastic component 3 bear the drive force of driving piece 4 and the reaction force of clamping jaw 21 respectively, elastic component 3 can elastic deformation, make the connection between driving piece 4 and the clamping jaw 21 be flexonics, elastic component 3 can cushion the effort between driving piece 4 and the clamping jaw 21, reduce the risk that the clamping jaw 21 extrudees damaging work piece 5 surface because of the too big driving force of driving piece 4. Because at least two clamping jaws 21 are used for clamping the same side face of a workpiece 5 in the clamp disclosed by the embodiment of the application, and the clamping jaws 21 are connected with the driving piece 4 through the elastic piece 3, the telescopic distance of the elastic piece 3 can be changed according to the sizes (such as the heights, the widths or the lengths) of different positions of the side face of the workpiece 5, so that when the driving piece 4 drives the clamping jaws 21 to clamp the workpiece 5 through the elastic piece 3, the movement distances of the clamping jaws 21 positioned on the same side face of the workpiece 5 can be different, namely, when the workpiece 5 is clamped, the relative positions of the clamping jaws 21 positioned on the same side face of the workpiece 5 can be different, and the clamp disclosed by the embodiment of the application can be used for clamping the workpiece 5 on the basis of adapting to the shape and the structure of the surface of the workpiece 5.
In this case, for ease of understanding, the structure of the workpiece 5 in fig. 1 is simplified, and features having different dimensions in the first direction X or in the second direction Y are illustrated only on the side of the workpiece 5. The first direction X is opposite to the second direction Y.
In addition, the number of the clamping jaws 21 on the same side or the number of the clamping jaws 21 on the same side for clamping the workpiece 5 in the clamp of the embodiment of the present application may be two, three, four or more. According to the shape and the structure of different workpieces 5, the clamping jaws 21 which can meet the requirement of clamping the workpieces 5 are arranged on the same side of the clamp in the embodiment of the application.

When the engine cylinder body is cleaned by the cleaning device, the top and the bottom of the engine cylinder body can be cleaned, and particularly the top of the engine cylinder body, which is provided with the piston port, can be comprehensively cleaned, so that the cleaning quality of the top and the inside of the piston port is improved. The clamp of the embodiment of the application also facilitates finishing the top and bottom of the engine block with other means of course.
The frame body 1 of the embodiment of the present application may be mounted on a robot arm so that the jig is used as an end operation member of the robot arm. Because the clamp of the embodiment of the application can be used for clamping the side surface of the engine cylinder body, the surface quality requirement on the side surface of the engine cylinder body is lower than the top surface quality requirement of the engine cylinder body, the contact area between the clamping jaw 21 used for clamping the side surface of the engine cylinder body and the engine cylinder body can be relatively smaller, namely, the volume of the clamping jaw 21 can be relatively smaller, the quality is smaller, and the work load of the mechanical arm is smaller.

Under this setting, two clamping jaw groups that set up relatively are mutually independent, can control two clamping jaw group respective driving piece 4 respectively to make two clamping jaw group's effort size to work piece 5 all be in suitable range, reduce the risk that work piece 5 was injured by arbitrary clamping jaw group clamp. Of course, the movement of the two clamping jaw sets can also be controlled respectively, so that the two clamping jaw sets can be abutted to the side face of the workpiece 5, thereby reliably clamping the workpiece 5, and reducing the possibility that the other clamping jaw set cannot move to the other side face of the workpiece 5 due to interference when one clamping jaw set is abutted to the side face of the workpiece 5. Therefore, the clamp of the embodiment of the application is high in working reliability.

Or, the number of the elastic pieces 3 is the same as the number of the clamping jaws 21 in the same clamping jaw group, namely, the elastic pieces 3 are connected with the clamping jaws 21 in a one-to-one correspondence manner, under the arrangement, under the condition that one of the elastic pieces 3 fails, the other elastic piece 3 can also have acting force on the connected clamping jaw 21, namely, the clamping reliability of the clamp in the embodiment of the application is higher. The description of the number of elastic members 3 in the following embodiments will mainly be given by taking the example that the number of elastic members 3 corresponds to the number of jaws 21, i.e. one elastic member 3 is connected to each of the two jaws 21 of the first jaw set 2a, and one elastic member 3 is connected to each of the two jaws 21 of the second jaw set 2b.
Furthermore, the number of driving members 4 of the same jaw set may be one, i.e. the driving members 4 may be connected to at least two elastic members 3 at the same time, so as to realize the movement of each jaw 21 of the same jaw set, and in this arrangement, the movement of the same jaw set is convenient to control, and the operation difficulty is low. Alternatively, the number of drives 4 of the same jaw set may be the same as the number of jaws 21, i.e. each jaw 21 may be connected to a separate spring 3 and a separate drive 4.

Taking the first clamping jaw set 2a as an example, when the workpiece 5 needs to be clamped by the clamp, the driving member 4 drives the second connecting member 212 to move along the first direction X through the elastic member 3, and the second connecting member 212 drives the body 211 to approach the workpiece 5 again, so that the body 211 clamps the workpiece 5. The driving member 4 is also directly connected to the second connecting member 212. When the fixture is required to be separated from the workpiece 5, the driving member 4 directly drives the second connecting member 212 to move along the second direction Y, and the second connecting member 212 drives the body 211 away from the workpiece 5 again, so that the body 211 is separated from the workpiece 5. The fixture of the embodiment of the application uses the second connecting piece 212 as a transmission piece between the driving piece 4 and the body 211, so that on one hand, the driving piece 4 can be installed at a position far away from the workpiece 5, the possibility that the driving piece 4 interferes with the workpiece 5 is reduced, or the possibility that the driving piece 4 is influenced by the severe environment where the workpiece 5 is located (for example, the environment where the workpiece 5 exists has liquid, chips and other impurities harmful to the driving piece 4), and the working reliability and the service life of the driving piece 4 are improved. On the other hand, with the second connecting member 212 as a transmission member between the driving member 4 and the body 211, the direction and magnitude of the driving force of the driving member 4 can be changed so that the body 211 clamps or separates from the workpiece 5 in an appropriate moving direction, and so that the magnitude of the force of the body 211 against the workpiece 5 is within a range capable of clamping the workpiece 5 without clamping the workpiece 5. Therefore, the clamp of the embodiment of the application is high in working reliability.
The frame body 1 may be a plate structure, the body 211 is located at one side of the frame body, the second connecting member 212, the elastic member 3 and the driving member 4 are located at the other side of the frame body 1, the second connecting member 212 is used to transmit the acting force of the driving member 4, and change the direction of the acting force, so that the body 211 moves along a preset direction, and the movement mode of the body 211 will be described in detail later herein.
In addition, the second connector 212 may be a rod-shaped structure, a hook-shaped structure, or a disc-shaped structure. The body 211 may have a generally rod-like structure or a claw-like structure. The subsequent embodiments herein mainly describe the second connection member 212 by taking a rod-like structure as an example, and describe the body 211 by taking a claw-like structure. The movement of the second connector 212 and the body 211 will be described in detail later herein.
Referring to fig. 5, the second connecting member 212 may include a blocking portion 212a, wherein one end of the blocking portion 212a abuts against the elastic member 3, and the other end of the blocking portion 212a abuts against the driving member 4.
In this embodiment, as shown in fig. 5, the driving member 4 is abutted to one end of the blocking portion 212a of the second connecting member 212 (one end of the blocking portion 212a close to the elastic member 3) through the elastic member 3. Taking the first clamping jaw set 2a as an example, when the workpiece 5 needs to be clamped by the clamp, the driving member 4 drives the elastic member 3 to move along the first direction X, and the elastic member 3 drives the blocking portion 212a to move along the first direction X, so that the second connecting member 212 drives the body 211 to approach the workpiece 5, so that the body 211 clamps the workpiece 5. The driving member 4 is further abutted against the other end (the end of the blocking portion 212a away from the elastic member 3) of the blocking portion 212a of the second connecting member 212, and when the clamp is required to be separated from the workpiece 5, the driving member 4 directly drives the blocking portion 212a to move along the second direction Y, so that the second connecting member 212 drives the body 211 to be far away from the workpiece 5, and the body 211 is separated from the workpiece 5. Under this setting, through the mode of butt, both can form the promotion effect along first direction X to the one end of fender portion 212a through elastic component 3 to driving piece 4, form flexonics between driving piece 4 and second connecting piece 212, thereby can cushion the effort between work piece 5 and the driving piece 4, driving piece 4 can also form the promotion effect along second direction Y to the other end of fender portion 212a, because there is not the intervention of elastic component 3, the connection between driving piece 4 and fender portion 212a is rigid connection, can drive the motion of second connecting piece 212 fast, and then second connecting piece 212 drives body 211 fast and breaks away from work piece 5.
Referring to fig. 5, the second connecting piece 212 may further include a first protruding portion 212b, where the first protruding portion 212b protrudes with respect to the blocking portion 212a, and at least a portion of the elastic piece 3 is sleeved on the first protruding portion 212b. The first protruding portion 212b can form a limiting effect on the elastic piece 3, so that the elastic piece 3 can be always abutted to the blocking portion 212a when the workpiece 5 is clamped, and reliability of flexible connection between the elastic piece 3 and the second connecting piece 212 is improved.
Referring to fig. 4 to fig. 6, the driving member 4 may include a first connecting portion 421 and a second connecting portion 422, wherein the first connecting portion 421 abuts against an end of the elastic member 3 facing away from the blocking portion 212a, and the second connecting portion 422 abuts against an end of the blocking portion 212a facing away from the elastic member 3.
In this embodiment, as shown in fig. 4 to 6, the first connecting portion 421 of the driving member 4 abuts against an end of the elastic member 3 facing away from the blocking portion 212a, and the second connecting portion 422 of the driving member 4 abuts against an end of the blocking portion 212a facing away from the elastic member 3. Taking the first clamping jaw set 2a as an example, when the workpiece 5 needs to be clamped by the clamp, the first connecting portion 421 forms a pushing effect along the first direction X on one end of the blocking connection portion 212a through the elastic member 3, so that the second connecting member 212 moves along the first direction X and drives the body 211 to clamp the workpiece 5, and the second connecting portion 422 is separated from the blocking connection portion 212a along the first direction X. When the clamp is required to be separated from the workpiece 5, because the first connecting portion 421 is abutted with one end of the elastic piece 3, which is away from the blocking portion 212a, and when the first connecting portion 421 moves along the second direction Y, the first connecting portion 421 cannot form a pulling force along the second direction Y on the elastic piece 3, or the first connecting portion 421 is separated from the elastic piece 3, so that the first connecting portion 421 cannot pull the second connecting piece 212 along the second direction Y through the elastic piece 3, and the second connecting portion 422 is abutted with one end of the blocking portion 212a, which is away from the elastic piece 3, and when the second connecting portion 422 moves along the second direction Y, a rigid connection effect exists between the second connecting portion 422 and the blocking portion 212a, and the second connecting portion 422 can form a pulling force along the second direction Y on the second connecting piece 212 and can quickly bring the second connecting piece 212 into a second direction Y movement, so that the clamping jaw 21 is quickly separated from the workpiece 5.
Wherein, the first connecting piece 42 further includes a second protruding portion 421a disposed on the first connecting portion 421, at least a portion of the elastic piece 3 is sleeved on the second protruding portion 421a, and the second protruding portion 421a can form a limiting effect on the elastic piece 3, when the workpiece 5 is clamped, the elastic piece 3 can be always abutted to the first connecting portion 421, so as to improve reliability of flexible connection between the elastic piece 3 and the first connecting portion 421.
Referring to fig. 6, the main body 211 is rotatably connected to the frame 1, the second connecting member 212 is rotatably connected to the main body 211, and the second connecting member 212 can drive the main body 211 to rotate under the driving of the driving member 4.
In this embodiment, please refer to fig. 6, the clamp in this embodiment changes the acting force direction of the driving member 4 by using the rotational connection, so that the body 211 rotates around the third direction Z relative to the frame body 1 to clamp or separate from the workpiece 5, under this setting, the structure of the driving member 4, the elastic member 3 and the clamping jaw 21 can be set more compactly, the volume of the clamp in this embodiment is smaller, the flexibility is higher, the convenience is higher during transferring, and the user experience is higher. The third direction Z is perpendicular to the first direction X.
Referring to fig. 3 to 6, taking the first jaw set 2a as an example, the driving member 4 pushes the elastic member 3 to move along the first direction X, and the elastic member 3 pushes the second connecting member 212 to move along the first direction X. Since the second connecting member 212 is flexibly connected to the elastic member 3, the second connecting member 212 is rotatably connected to the body 211, and the body 211 is rotatably connected to the frame 1, so that the second connecting member 212 can drive the body 211 to rotate around the third direction Z in the view angle shown in fig. 4, and the body 211 can approach the workpiece 5 until the body 211 clamps the workpiece 5. In the view shown in fig. 6, the portion of the body 211 that can abut against the workpiece 5 has a tendency to move in the second direction Y due to the transmission of the second link 212, so that the workpiece 5 can be clamped. Accordingly, the driving member 4 can directly push the second connecting member 212 to move along the second direction Y, and in the view angle shown in fig. 4, the second connecting member 212 can drive the body 211 to reversely rotate around the third direction Z, so that the body 211 can be separated from the workpiece 5. In the view shown in fig. 6, the portion of the body 211 that can abut against the workpiece 5 has a tendency to move in the first direction X due to the transmission of the second coupling member 212, so that the workpiece 5 can be detached.
Of course, the body 211 may also be slidably connected with the frame body 1, the second connecting member 212 is rotatably connected with the body 211, and the second connecting member 212 can drive the body 211 to slide under the driving of the driving member 4, so as to clamp or separate the body 211 from the workpiece 5.
