Detailed implementation manners

[0023] To further illustrate each embodiment, the present utility model provides drawings. These drawings are a part of the disclosure of the present utility model, mainly used to illustrate the embodiments, and can cooperate with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] The present utility model will be further described below in conjunction with the drawings and specific implementation manners.

[0025] Referring to Figure 1 and 2 In this embodiment, a turntable type fixture device is provided. The turntable type fixture device can be installed on a workbench. The turntable type fixture device includes a horizontally arranged turntable 1, a driving member 2 for driving the turntable 1 to rotate, a clamping assembly 3, and a fixed seat 4. In this embodiment, a first station 5, a second station 6, a third station 7, and a fourth station 8 are sequentially arranged on the workbench along the clockwise rotation direction of the turntable 1. Among them, the first station 5 and the fourth station 8 are respectively a loading station and an unloading station, and it is required that the clamping assembly 3 is in a state of loosening the workpiece to meet the loading and unloading operations of the workpiece by external equipment. The second station 6 and the third station 7 are both processing stations, and it is required that the clamping assembly 3 is in a state of clamping the workpiece to meet the processing operations of the workpiece by external equipment. Four groups of clamping assemblies 3 are evenly spaced along the circumferential direction of the turntable 1 corresponding to the four stations. The fixed seat 4 is fixedly installed on the workbench, is relatively independently arranged with the turntable 1, and is respectively arranged on the first station 5 and the fourth station 8 to cooperate with the clamping assembly 3 to realize the loosening action of the workpiece.

[0026] Referring to Figure 3 and 4, the clamping assembly 3 includes a base 31, a fixing part 32, a movable part 33, a reset part and an elastic part. The base 31 is fixedly installed on the turntable 1; the fixing part 32 is a block structure and is fixedly installed on the base 31; the movable part 33 is a block structure and is slidably installed on the base 31. The elastic part is installed on the base 31 and is drivingly connected to the movable part 33. The elastic part can release energy to drive the movable part 33 to move towards the fixing part 32, so that the workpiece is clamped between the movable part 33 and the fixing part 32. The reset part is connected to the movable part 33; as the turntable 1 rotates, the reset part can abut against the fixed seat 4, so that the movable part 33 moves away from the fixing part 32 to compress the elastic part, and as the turntable 1 rotates, the reset part can disengage from the fixed seat 4, so that the elastic part releases energy to drive the movable part 33 to move towards the fixing part 32. Thus, at the station where the workpiece needs to be loosened, by the abutment of the reset part and the fixed seat 4, the clamping assembly 3 does not limit the workpiece, and the workpiece can be put in or taken out; at the station where the workpiece needs to be clamped, since the reset part disengages from the fixed seat 4, under the action of the released energy of the elastic part, the workpiece can be clamped between the movable part 33 and the fixing part 32. By utilizing the elastic potential energy of the elastic part and the cooperation of the reset part and the fixed seat 4, the movable part 33 can move towards or away from the fixing part 32, thereby realizing the clamping or loosening action of the workpiece, without the need for an additional mechanism such as a cylinder as a driving source to clamp or loosen the workpiece, making the structure of the whole fixture device simpler and reducing the equipment cost.

[0027] Specifically, referring to Figure 4 and 5, the fixed seat 4 is arranged outside the circumferential side of the turntable 1. The reset part includes a cylindrical reset rod 34. One end of the reset rod 34 is fixedly connected to the movable part 33. The reset rod 34 movably penetrates through the fixed part 32 and extends towards the outside of the turntable 1. The end of the reset rod 34 away from the movable part 33 can abut against the fixed seat 4 as the turntable 1 rotates. During the process that the reset rod 34 rotates with the turntable 1 and abuts against the fixed seat 4, the length of the reset rod 34 extending outside the turntable 1 gradually becomes shorter and then longer; during the process that the length of the reset rod 34 extending outside the turntable 1 gradually becomes shorter, the movable part 33 can be driven to move away from the fixed part 32. During the process that the length of the reset rod 34 extending outside the turntable 1 gradually becomes longer, that is, the movable part 33 moves towards the fixed part 32 under the energy release of the elastic part; thus, clamping or loosening of the workpiece is realized. In this embodiment, the end of the reset rod 34 away from the movable part 33 is set as a hemispherical head structure, which can reduce the friction force generated between the reset rod 34 and the fixed seat 4 and ensure that the reset rod 34 can smoothly push the movable part 33 to move. In other embodiments, the fixed seat 4 can also be arranged above the turntable 1 through other external connecting components. The reset rod 34 is vertically installed on the movable part 33. The fixed seat 4 can be provided with an arc part. The outer wall of the reset rod 34 can abut against the arc part on the fixed seat 4. The reset rod 34 moves along the arc track on the fixed seat 4 as the turntable 1 rotates, and cooperates with the elastic part, so that the movable part 33 can approach or move away from the fixed part 32, realizing clamping or loosening of the workpiece. That is, as long as the fixed seat 4 is arranged, during the process that the reset rod 34 rotates with the turntable 1 and abuts against the fixed seat 4, and then cooperates with the elastic part to enable the movable part 33 to approach or move away from the fixed part 32.

[0028] The elastic part includes a spring 35. An installation seat 311 is fixedly installed on the base 31 through bolts. The installation seat 311 is located on the side of the movable part 33 away from the fixed part 32. Two springs 35 are arranged at intervals along the length direction of the installation seat 311. One end of the spring 35 abuts against the installation seat 311, and the other end abuts against the movable part 33. The number of the springs 35 and the elastic coefficient of the springs 35 can be adaptively adjusted and replaced according to the magnitude of the clamping force required by the workpiece. The energy release of the spring 35 drives the movable part 33 to move towards the fixed part 32, thereby realizing the clamping action of the workpiece. A guide rail 312 is fixedly installed on the base 31. The guide rail 312 is arranged along the radial direction of the turntable 1. The bottom of the movable part 33 is detachably and fixedly installed with a slider 331. The slider 331 is slidably installed on the guide rail 312. Through the arrangement of the guide rail 312, the movement track of the movable part 33 can be determined, and the movement of the movable part 33 towards or away from the fixed part 32 can be made smoother.

[0029] Further, an annular baffle 11 is arranged along the circumferential direction of the turntable 1. The reset rod 34 movably penetrates through the baffle 11. In this way, the hole position on the baffle 11 can provide a guiding effect for the movement of the reset rod 34, and the baffle 11 can play a certain supporting role for the reset rod 34, so that the reset rod 34 can smoothly move along its axial direction during the process of abutting against the fixed seat 4, reducing the phenomenon of jamming.

[0030] Further, a first clamping block 321 is detachably installed on the fixing part 32, and a second clamping block 332 is detachably installed on the moving part 33. The workpiece is placed between the first clamping block 321 and the second clamping block 332. Through the detachable installation and fixation of the first clamping block 321 and the second clamping block 332, it is convenient to replace the first clamping block 321 and the second clamping block 332 to adapt to clamping different workpieces. The driving member 2 includes a motor and a commutation mechanism. The output end of the motor is connected to the commutation mechanism, and the output end of the commutation mechanism is connected to the turntable 1 to drive the turntable 1 to rotate.
