Description

Technical Field

[0001] The present application relates to the field of maintenance devices for heliostat products, and particularly to a positioning tooling and tapping method for heliostat components. Background Art

[0002] Most of the heliostat assembly products are fixed by riveting the reflector and the mirror frame. The reflector needs to be bonded to the mirror support first, and then the mirror support is threadedly connected to the screw rod and then riveted to the mirror frame. During the production and assembly process, it is easy to occur that due to manual operation errors or software program errors, the internal threads of individual mirror supports are not tapped or the tapping is not in place. In addition, there is also a phenomenon that the central symmetric threaded holes of the torque beam and the support seat are not tapped. To ensure the production progress of the product, manual tapping repair is carried out at the production site. The tapping tool consists of a tap and a tap handle. After the operator installs the tap and the tap handle, the tapping is carried out along the axial direction of the hole position. However, due to the lack of a positioning tool, the rate is slow during the manual tapping process, and it is easy to deviate from the axis of the tapping, resulting in thread offset. Especially for the mirror support assembly, the eccentricity of one threaded hole may even cause the entire reflector assembly to be scrapped. Summary of the Invention

[0013] The realization, functional features, and advantages of the object of the present application will be further described in conjunction with the embodiments with reference to the drawings. Detailed Embodiments

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0015] The first embodiment of the present invention provides a positioning tooling for a heliostat component, as Figure 1-2 shown, Figure 2 where a is a perspective view, Figure 2 b is a top view, Figure 2 c is a bottom view, including a first frustum 1, a first through hole 2 and a plurality of second through holes 3 are axially provided along the first frustum 1, and the plurality of second through holes 3 are distributed along the outer circumference of the first through hole 2; a first boss 4 is fixed on the surface of the first frustum 1, a third through hole 5 is provided on the first boss 4, the third through hole 5 is located above the first through hole 2 and communicates with the first through hole 2; a first positioning groove 6 is provided at the position of the second through hole 3 on the surface of the first frustum 1, the first positioning groove 6 communicates with the second through hole 3, the inner diameter of the first positioning groove 6 is larger than the inner diameter of the through hole, and the first positioning groove 6 and the first boss 4 are on the same side of the first frustum 1.

[0016] Furthermore, it further includes a positioning rod 7. The positioning rod 7 includes a positioning head, the positioning head is connected with a connecting rod, the outer diameter of the connecting rod is the same as the inner diameter of the second through hole 3, the outer diameter of the positioning head is the same as the inner diameter of the first positioning groove 6, and the positioning head is in close fit with the first positioning groove 6. Exemplarily, the positioning rod 7 is a screw. There are four first positioning grooves 6, and each first positioning groove 6 communicates with the corresponding second through hole 3.

[0017] Based on the above solution, it is possible to perform center-symmetric tapping on the torque beam and the support seat, etc. The tapping will be introduced below taking the support seat as an example. A center through hole and a hole to be tapped are provided on the support seat. The specific tapping method is as follows: insert the connecting rod (screw rod) into the normal threaded hole on the opposite side of the hole to be tapped, the positioning head (screw head) is located in the first positioning groove 6, and the first boss 4 is located in the center through hole, and make the tap extend into the hole to be tapped on the opposite side along the second through hole 3 for tapping. If the normal threaded hole is not on the opposite side of the hole to be tapped position, the fixing screw 3 can be installed in the remaining normal threaded holes around, and after the tooling is assembled and matched, ensure that there is no gap on the horizontal plane, and then start the tapping operation. Because the positioning rod 7 is in close fit with the first positioning groove 6, it is not easy to cause shaking and influence.

[0018] In this embodiment, through the cooperation of the first frustum 1 and the positioning rod 7, center-symmetric tapping of threaded holes can be achieved for the torque beam, support seat, etc. The support seat, etc. and the first frustum 1 are positioned and connected through the positioning rod 7 to ensure accurate positioning and avoid shaking. The tap extends into the hole to be tapped along the second through-hole 3 for tapping, avoiding tap deviation.

[0019] Furthermore, as Figures 3-5 shown, Figure 5 a is a perspective view, Figure 5 b is a top view, Figure 5 c is a bottom view. The positioning tooling further includes a second frustum 8. A positioning post 9 adapted to the second through-hole 3 is fixed on one surface of the second frustum 8. The positioning post 9 is located in the second through-hole 3, and a second boss 10 is fixed on the other surface. A positioning hole 11 is provided at the center position of the second frustum 8.

[0020] A third boss 15 is fixed on the surface of the first frustum 1. A fourth through-hole 16 is provided in the third boss 15. The fourth through-hole 16 is located below the first through-hole 2 and communicates with the first through-hole 2. The third boss 15 is located in the positioning hole 11. The height of the third boss 15 is less than the depth of the positioning hole 11, and the third boss 15 and the positioning hole 11 form a groove. The cooperation between the third boss 15 and the positioning hole 11, combined with the cooperation between the second through-hole 3 and the positioning post 9, forms a 1+1 fixed interlock. Further, there are four second bosses 10, and the four second bosses 10 are distributed along the circumference of the positioning hole 11, which can further improve the stable positioning and avoid tapping deviation from the axis. The heliostat assembly includes a mirror support 12 and a mirror support boss 13. Four through-holes 14 are provided in the mirror support 12. When tapping the mirror support 12, the mirror support boss 13 is located in the groove formed by the third boss 15 and the positioning hole 11. Under the positioning and clamping of the second bosses 10, the coaxiality of the threaded hole of the mirror support 12 and the first through-hole 2 can be effectively improved, ensuring no eccentricity during tapping.

[0021] The second embodiment of the present invention provides a tapping method for a positioning tooling using a heliostat assembly, which specifically includes: The second frustum 8 is sleeved on the mirror support boss 14 through the positioning hole 11, and the second frustum 8 is rotated so that the four second bosses 10 are located in the corresponding through-holes 14. The tap is extended into the hole to be tapped of the mirror support boss 13 along the third through-hole 5, the first through-hole 2, and the positioning hole 11 for manual tapping operation.

[0022] In this embodiment, the second boss 10 can be inserted into the through-hole 14, and there is a 1 mm margin after the second boss 10 is inserted into the through-hole 14 to avoid the second boss 10 touching the bottom glass and causing breakage. Through the positioning limit, the stability and accuracy of manual tapping are improved, the difficulty of holding the tap is reduced, and thus the manual tapping rate can be increased.
