[0003] The base body of the existing device for installing the clamp is mostly fixed to the robot arm by a screw. When the screw is slipped, it will make disassembly difficult, affecting the disassembly efficiency. When there is a slight bump on the edge of the screw adjustment part, the wrench will not be able to engage with the screw adjustment part, affecting the replacement efficiency. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the utility model provides a manipulator that is easy to replace the clamping jaws, so as to solve the problem that the base body used to install the clamping jaws in the existing devices is mostly fixed to the manipulator by a screw. When the screw is slipped, it will cause difficulty in disassembly, affecting the disassembly efficiency; when there is a slight bump on the edge of the screw adjustment position, it will cause the wrench to be unable to engage with the screw adjustment position, affecting the replacement efficiency.

[0005] The purpose and effect of the utility model of a manipulator that is convenient for replacing clamping claws are achieved by the following specific technical means:

[0006] A manipulator convenient for replacing clamping jaws comprises a fixing seat which is fixed on a manipulator arm and a seat body is fixed at the bottom of the fixing seat via two fixing screws.

[0007] Furthermore, two cylindrical rod-shaped guide rods are symmetrically welded to the top of the seat body, and both guide rods pass through the fixing seat.

[0008] Furthermore, the upper ends of the two guide rods are polished, and after the polishing, the upper ends of the two guide rods are arc-shaped structures.

[0009] Furthermore, the adjustment portions of the two fixing screws are both hexagonal structures, and an auxiliary groove is provided at the adjustment portion of each fixing screw, and the auxiliary groove is a hexagonal groove structure.

[0010] Furthermore, the seat body is a stepped structure, and the middle parts of the two fixing screws are exposed.

[0011] Furthermore, two connecting blocks are welded on the bottom end surface of the seat body, both of which are rectangular block structures, and two guide rods with cylindrical rod structures are welded between the two connecting blocks, and two clamping claws are slidably connected to the two guide rods.

[0012] Furthermore, an adjustment rod is inserted into the two connecting blocks, and the left end and the right end of the adjustment rod are respectively threadedly connected to the two clamping claws. An electric motor is fixed to the right end face of a right connecting block, and the rotating shaft of the motor is fixed to the adjustment rod.

[0013] Furthermore, the thread directions of the left end and the right end of the adjusting rod are opposite, and when the adjusting rod rotates, the two clamping claws are in a synchronous reverse movement state.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the present application, through the setting of the seat body, since the seat body is a stepped structure, the middle parts of the two fixing screws are exposed. When the fixing screws are stripped, the fixing screws can be directly cut off from the middle parts, which is convenient for troubleshooting and replacement. Moreover, the fixing seat and the seat body will not be damaged when the fixing screws are cut off, and the practicality is high.

[0016] In the present application, by setting the fixing screw and the auxiliary groove, on the one hand, when replacing the seat body and the claw part installed on the seat body, the two fixing screws can be directly removed, and the replacement is convenient; on the other hand, when the outer side of the fixing screw is slightly deformed, the wrench or the sleeve mirror cannot be engaged with the adjustment part of the fixing screw. An Allen wrench can be used to insert it into the auxiliary groove and rotate it. At this time, the fixing screw can be disassembled, which facilitates the replacement of the seat body.

[0017] In the present application, by setting the guide rods, when the seat body and the fixing seat are fixed, the two guide rods are fixed to the seat. At this time, the fixing hole on the seat body for the fixing screw to pass through is aligned with the threaded hole on the fixing seat, which facilitates the installation of the seat body and also facilitates replacement.

[0018] In the present application, through the setting of the adjustment rod, since the thread directions of the left end and the right end of the adjustment rod are opposite, when the adjustment rod is rotated, the two clamping claws are in a synchronous reverse movement state. When clamping is required, the two clamping claws are moved to the left and right sides of the clamped part, and the motor is controlled to rotate. When the motor rotates, it can drive the adjustment rod to rotate. Under the thread drive of the adjustment rod, the two clamping claws can be adjusted synchronously in reverse, and the clamping efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment 1:

[0031] As attached Figure 1 To Attachment Figure 6 As shown:

[0032] The utility model provides a manipulator convenient for replacing clamping claws, comprising a fixing seat 1; the fixing seat 1 is fixed on a mechanical arm, and a seat body 201 is fixed at the bottom of the fixing seat 1 through two fixing screws 202.

[0033] Two cylindrical rod-shaped guide rods 203 are symmetrically welded on the top of the seat body 201 , and both guide rods 203 pass through the fixing seat 1 .

[0034] Among them, the upper ends of the two guide rods 203 are polished. After polishing, the upper ends of the two guide rods 203 are arc-shaped structures. When the seat body 201 is fixed to the fixed seat 1, the two guide rods 203 are fixed to the seat 1. At this time, the fixing hole on the seat body 201 for fixing the screw 202 is aligned with the threaded hole on the fixed seat 1, which facilitates the installation of the seat body 201.

[0035] Among them, the adjustment parts of the two fixed screws 202 are both hexagonal structures, and each of the fixed screws 202 is provided with an auxiliary groove 204. The auxiliary groove 204 is a hexagonal groove structure. During use, when the outer side of the fixed screw 202 is slightly deformed, the wrench or the sleeve mirror cannot be engaged with the adjustment part of the fixed screw 202. You can use an inner hexagon wrench to insert it into the auxiliary groove 204 and rotate it. At this time, the fixed screw 202 can be disassembled, which facilitates the replacement of the seat body 201.

[0036] Among them, the seat body 201 is a stepped structure, and the middle parts of the two fixed screws 202 are exposed. When the fixed screws 202 are stripped, the fixed screws 202 can be cut directly from the middle part of the fixed screws 202, which is convenient for troubleshooting and replacement, and the fixed seat 1 and the seat body 201 will not be damaged when cutting the fixed screws 202.

[0037] Among them, two connecting blocks 205 are welded on the bottom end surface of the base body 201. Both connecting blocks 205 are rectangular block structures. Two cylindrical rod-shaped guide rods 206 are welded between the two connecting blocks 205. Two clamping claws 207 are slidably connected to the two guide rods 206.

[0038] Among them, an adjustment rod 209 is inserted into the two connecting blocks 205, and the left end and the right end of the adjusting rod 209 are respectively threadedly connected to the two clamping claws 207, and a motor 208 is fixed to the right end face of the right connecting block 205, and the rotating shaft of the motor 208 is fixed to the adjusting rod 209.

[0039] Embodiment 2:

[0040] On the basis of Example 1, the thread directions of the left end and the right end of the adjustment rod 209 are opposite. When the adjustment rod 209 rotates, the two clamping claws 207 are in a synchronous reverse movement state. When clamping is required, the two clamping claws 207 are moved to the left and right sides of the clamped part, and the motor 208 is controlled to rotate. When the motor 208 rotates, it can drive the adjustment rod 209 to rotate. Under the thread drive of the adjustment rod 209, the synchronous reverse adjustment of the two clamping claws 207 can be achieved.

[0041] Working principle: When the seat body 201 is fixed to the fixing seat 1, the two guide rods 203 are fixed to the seat 1. At this time, the fixing hole on the seat body 201 through which the fixing screw 202 passes is aligned with the threaded hole on the fixing seat 1, which facilitates the installation of the seat body 201; when clamping is required, the two clamping claws 207 are moved to the left and right sides of the clamped part, and the motor 208 is controlled to rotate. When the motor 208 rotates, it can drive the adjustment rod 209 to rotate. Under the thread drive of the adjustment rod 209, the two clamping claws 207 can be adjusted in the opposite direction synchronously; During replacement, when the outer side of the fixing screw 202 is slightly deformed, the wrench or the sleeve mirror cannot engage with the adjustment part of the fixing screw 202, and an Allen wrench can be inserted into the auxiliary groove 204 and rotated. At this time, the fixing screw 202 can be disassembled, which facilitates the replacement of the seat body 201; when the fixing screw 202 is stripped, the fixing screw 202 can be directly cut off from the middle part of the fixing screw 202, which facilitates troubleshooting and replacement, and the fixing seat 1 and the seat body 201 will not be damaged when the fixing screw 202 is cut off.
