Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of production and processing of radomes, and specifically relates to an external turning fixture for a radome. Background Art
[0002] The external turning fixture of a radome vehicle is a mechanism used to clamp a radome on a lathe to ensure the stability of the radome, facilitate the production and processing of the radome, and improve the processing quality and efficiency of the radome.
[0003] For the existing external turning fixture of a radome vehicle, the positioning blocks for positioning the front and rear ends of radomes of different sizes are usually custom-made, and after production, the slope and size of the positioning blocks need to be finely adjusted according to the inner hole size of the blank parts. The processing cycle is prolonged and the labor cost is increased. After the first batch of production of radomes of the same specification is completed, if the second batch of production is to be started, the custom-made positioning blocks need to be reinstalled. Due to different lathe sizes and different clamping angles, it is very difficult to ensure the accuracy of the first clamping during the clamping process, resulting in a decrease in the accuracy of external turning. After the production of radomes of one specification is completed, the remaining positioning blocks are difficult to reuse and most of them are scrapped, increasing the economic cost.
[0004] To solve this problem, the utility model proposes an external turning fixture for a radome. Summary of the Invention

[0029] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model in conjunction with the accompanying drawings of the specification.
[0030] In the following description, many specific details are set forth to facilitate a thorough understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0031] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments. The present utility model provides the following embodiments.
[0032] As Figure 1 And Figure 2 As shown, it is a schematic structural diagram of the outer circular fixture of the radome in this embodiment. The outer circular fixture of the radome in this embodiment includes a connecting mechanism 100 and a clamping assembly 200. The outer circular fixture of the radome in this embodiment is assembled on the lathe through the connecting mechanism 100. The connecting mechanism 100 in this embodiment includes a lathe connecting plate 101. The lathe connecting plate 101 is fixedly installed on the lathe, thereby realizing the fixation of the entire outer circular fixture of the radome on the lathe. In this embodiment, a connecting shaft 102 is fixedly installed on the lathe connecting plate 101. A chuck fixing plate 103 is fixedly connected to the end of the connecting shaft 102. An opening is provided at the center position of the chuck fixing plate 103. The outer circular fixture of the radome in this embodiment further includes a support rod 104. The support rod 104 passes through the opening and is locked to the lathe connecting plate 101 by bolts.
[0033] In this embodiment, the end of the support rod 104 is a positioning block 105, and a clamping assembly 200 is installed on the chuck fixing plate 103. The clamping assembly 200 surrounds the outside of the support rod 104. When machining the radome is required, the support rod 104 extends into the radome, abuts against the inner wall of the front end of the radome through the positioning block 105, and clamps the rear end of the radome through the clamping assembly 200 to maintain the stability of the radome.
[0034] As Figures 3 to 6As shown, it is a schematic structural diagram of the clamping assembly 200 in this embodiment. The clamping assembly 200 in this embodiment includes a chuck housing 201. The chuck housing 201 is fixed on the chuck fixing plate 103, and clamping heads 202 are annularly distributed on the surface of the chuck housing 201. There are multiple clamping heads 202, preferably 3 in this embodiment. The radome sleeved on the support rod 104 is clamped by the relative sliding of the clamping heads 202 with respect to the chuck housing 201.
[0035] In this embodiment, when the radome is sleeved on the support rod 104 and moves, the positioning block 105 at the end of the support rod 104 is grounded on the inner wall of the top end of the radome, and the clamping head 202 slides relative to the surface of the chuck housing 201 and abuts against the side wall at the rear end of the radome, so that the radome can be clamped to facilitate the lathe to process the radome.
[0036] As Figure 5 and Figure 6 As shown, in this embodiment, a chute 201a is provided on the surface of the chuck housing 201, and the clamping head 202 is slidably installed in the chute 201a. When the radome needs to be clamped, the clamping head 202 slides in the chute 201a relative to the chuck housing 201 until the clamping head 202 clamps the radome outside the support rod 104.
[0037] As Figures 6 to 8 As shown, in this embodiment, a gear disk 203 is rotatably installed in the chuck housing 201, and the surface of the gear disk 203 communicates with the chute 201a. A spiral rack 203a is spirally distributed on the surface of the gear disk 203, and spiral tooth grooves are formed between the spiral racks 203a. In addition, teeth 202a are distributed at the bottom of the clamping head 202. In this embodiment, the teeth 202a are engaged with the spiral tooth grooves. Therefore, when the gear disk 203 rotates, the clamping head 202 can be driven to move along the length direction of the chute 201a on the surface of the chuck housing 201 through the engagement of the teeth 202a with the spiral tooth grooves. Therefore, in this embodiment, when the radome outside the support rod 104 needs to be clamped, the gear disk 203 is driven to rotate, and then the clamping head 202 can be driven to move on the surface of the chuck housing 201 to clamp the radome to ensure the stability of the radome.
[0038] In this embodiment, through the abutment of the positioning block 105 on the inner wall of the end of the radome and the cooperation of the clamping head 202 to clamp the side wall at the rear end of the radome, the radome can be firmly fixed on the lathe, so as to facilitate the lathe to process the radome and ensure the stability of the radome.
[0039] In addition, as Figures 6 to 8As shown in the figure, in this embodiment, a plurality of rotation holes are distributed on the side wall of the chuck housing 201. A chuck bevel gear 204 is rotatably installed in the rotation holes. In this embodiment, conical teeth are distributed at the lower end of the tooth disc 203. The lower end of the tooth disc 203 is meshed with the chuck bevel gear 204 through the conical teeth. Therefore, when the chuck bevel gear 204 rotates, it can drive the tooth disc 203 to rotate, and then drive the clamping head 202 to move, so as to facilitate the clamping head 202 to clamp the radome.
[0040] In this embodiment, in order to ensure the stability of the chuck bevel gear 204 in the rotation hole of the chuck housing 201, a rotating ring is rotatably installed in the rotation hole of the chuck housing 201. The chuck bevel gear 204 is rotatably installed in the rotating ring. And a limit pin hole is provided at the connection between the chuck bevel gear 204 and the rotating ring, and a limit pin is inserted. By inserting the limit pin, the degree of freedom of the chuck bevel gear 204 in the axial direction of the rotation hole is restricted, preventing the problem that the chuck bevel gear 204 is disengaged from the chuck housing 201. In addition, when the chuck bevel gear 204 rotates, the rotating ring can also rotate in the rotation hole. Therefore, the setting of the limit pin avoids the disengagement of the chuck bevel gear 204 from the rotation hole on the one hand, and does not affect the rotation of the chuck bevel gear 204 in the rotation hole on the other hand, ensuring the stability of the chuck bevel gear 204 during the rotational movement. By the rotation of the chuck bevel gear 204, the clamping head 202 can be driven to move so as to clamp and fix the radome, which is convenient to operate and also ensures the stability of the radome, so as to facilitate the lathe to process the radome.
[0041] When the radome turning outer circle fixture in this embodiment clamps the radome, the radome is sleeved on the support rod 104. The positioning block 105 at the end of the support rod 104 abuts against the inner wall of the top end of the radome. And the chuck bevel gear 204 rotates to drive the tooth disc 203 to rotate. During the rotation of the tooth disc 203, through the meshing action of the tooth teeth 202a and the spiral tooth groove, the clamping head 202 can be driven to move towards the radome side until the clamping heads 202 cooperate with each other to clamp the radome, thereby ensuring the stability of the radome. By processing the radome with a lathe, the processing efficiency is ensured and the processing quality is improved at the same time.
[0042] The above content further elaborates on the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as falling within the protection scope determined by the claims submitted for the present invention.
