Description

Technical Field

[0001] The utility model relates to the technical field of long stator linear motors, in particular to a tooling clamp for a long stator linear motor. Background Art

[0002] The components of the maglev long stator linear motor mainly consist of an iron core, a dovetail key, and an epoxy resin package. The length of the long stator linear motor is 1030 mm, the width is 185 mm, and the thickness of the package layer is 1 - 2 mm. Since the assembly accuracy of the dovetail key and the iron core of the long stator linear motor and the dimensional accuracy of the package layer thickness will affect the distribution of magnetic lines of force, and thus affect the running stability of the maglev train, it is necessary to measure the assembly accuracy and the package accuracy of the long stator linear motor to ensure that the product accuracy is within 0.1 mm.

[0003] Traditional manual measurement not only has low efficiency, but also is difficult to meet the design requirements in terms of accuracy. When using a coordinate measuring machine for detection, due to the limitation of the probe length, it is impossible to effectively obtain measurement data points, and the product needs to be rotated to facilitate the acquisition of data points. However, the weight of this product is greater than 120 kg. Manual rotation is not only laborious, but also prone to causing safety accidents and quality accidents. Therefore, in order to improve the measurement efficiency, it is necessary to improve the structure of the tooling clamp. Summary of the Utility Model

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 , Figure 3As shown in the figure, in order to be able to clamp both ends of the long stator body, both groups of clamping brackets 11 are in a U-shape and the mouths of the U-shapes are opposite to each other. The inner side walls of the clamping brackets 11 are connected with clamping jaws 12 through a clamping drive structure. The side view cross-section of the clamping jaws 12 is in a U-shape with the mouth facing downwards and the heights of the front and rear side walls are less than the height of the long stator body. The clamping drive structure includes a handwheel 13 and a screw rod 19. The screw rod 19 is threadedly connected to the upper wall of the clamping bracket 11. The handwheel 13 is fixedly connected to one end of the screw rod 19 away from the clamping bracket 11. One end of the screw rod 19 away from the handwheel 13 penetrates through the upper wall of the clamping bracket 11 and extends into the inner side wall of the clamping bracket 11. One end of the screw rod 19 extending into the inner side wall of the clamping bracket 11 is rotatably connected to the upper wall of the clamping jaw 12. The two groups of lifting arms are hoisted to both ends of the long stator body by a lifting device. Manually operate to put the clamping brackets 11 on the ends of the long stator body, and drive the screw rod 19 to rotate by rotating the handwheel 13. When the screw rod 19 rotates, through the threaded connection relationship with the upper wall of the clamping bracket 11, it drives the clamping jaw 12 to approach the long stator body and clamp the long stator body. The clamping jaw 12 being in a U-shape with the mouth facing downwards enables the front and rear sides to avoid the risk of the long stator body slipping;

[0027] As Figure 1 shown in the figure, in order to achieve the purpose of protecting the long stator body, a protection structure for protecting the long stator body when clamping is provided between the clamping jaw 12 and the inner side of the clamping bracket 11. The protection structure includes two groups of protection pads 14. The two groups of protection pads 14 are respectively arranged on the inner side wall of the clamping jaw 12 and the inner lower wall of the clamping bracket 11. When clamping, the two groups of protection pads 14 are padded between the clamping jaw 12 and the long stator body and between the clamping bracket 11 and the long stator body, which can effectively prevent the long stator body from being damaged;

[0028] As Figure 1 、 Figure 2 shown in the figure, in order to facilitate measurement, a rotation drive structure for driving the long stator body to rotate to adjust the detection position is provided on the upper wall of the right hanging arm 8. The rotation drive structure includes a servo motor 16, a synchronous belt 18 and two groups of synchronous pulleys 17. The servo motor 16 is fixedly connected to the upper wall of the right hanging arm 8 through a motor fixing bracket 15. The two groups of synchronous pulleys 17 are respectively fixedly connected to the end of the protruding shaft of the servo motor 16 and the outer wall of the second rotating shaft 10. The synchronous belt 18 is sleeved on the outer walls of the two groups of synchronous pulleys 17. The servo motor 16 can control the rotation angle and speed through an existing control device on the market. With the cooperation of the two groups of synchronous pulleys 17 and a group of synchronous belts 18, the long stator body can be driven to rotate to achieve the purpose of switching the measurement position.

[0029] Working principle: Lift the two groups of boom arms to both ends of the long stator body through the lifting device. Manually operate to put the clamping frame 11 on the end of the long stator body, and drive the screw 19 to rotate by turning the handwheel 13. When the screw 19 rotates, due to the threaded connection relationship with the upper wall of the clamping frame 11, it drives the clamping jaws 12 to approach the long stator body and clamp the long stator body. The clamping jaws 12 are in a C-shaped with the opening facing downwards, so that the front and rear sides can avoid the risk of the long stator body slipping. When clamping, the two groups of protective pads 14 are placed between the clamping jaws 12 and the long stator body and between the clamping frame 11 and the long stator body, which can effectively prevent the long stator body from being damaged. The servo motor 16 can control the rotation angle and speed through the existing control device on the market. Cooperating with the two groups of synchronous pulleys 17 and a group of synchronous belts 18 can drive the long stator body to rotate, achieving the purpose of switching the measurement position.
