DETAILED DESCRIPTION

[0027] The following is a further detailed description of an assembly table for clamping and fixing proposed by the utility model in combination with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become more clear according to the following description and claims.

[0028] See also Figures 1 to 4 The present embodiment provides an assembly table for clamping and fixing, the bottom of which is a box body 1 structure, the inside of which is provided with a hydraulic assembly extending along the height direction of the box body 1, the hydraulic assembly comprising a hydraulic cylinder 2 fixedly connected to the bottom surface of the box body 1, and a support rod 3 which can be vertically moved under the action of the hydraulic cylinder 2, wherein the cross section of the support rod 3 is rectangular, and first racks 4 extending and arranged are respectively provided on the vertically opposite side walls of the support rod 3. A first roller 5 and a second roller 6 which are arranged perpendicular to the support rod 3 are respectively provided on both sides of the first rack 4 of the support rod 3 in the box body 1, and gears 7 are respectively sleeved on the outer sides of the first roller 5 and the second roller 6. The gears 7 of the first roller 5 and the second roller 6 are respectively meshed and connected with the first racks 4 on both sides of the support rod 3, that is, during the vertical movement of the support rod 3, the first roller 5 and the second roller 6 are meshed and connected with the first racks 4 on both sides of the support rod 3, that is, during the vertical movement of the support rod 3, the first roller 5 and the second roller 6 are meshed and connected with the gears 7 and the first rack 4, and the first roller 5 and the second roller 6 will generate corresponding rotation, wherein the sizes of the first roller 5 and the second roller 6, the sizes of the gears 7 on the outer sides of the first roller 5 and the second roller 6, and the sizes of the first racks 4 on both sides of the support rod 3 are relatively consistent, so during the vertical movement of the support rod 3, the rotation changes generated by the first roller 5 and the second roller 6 are also consistent.

[0029] A first movable plate 8 and a second movable plate 9 are further provided in the box body 1. The first movable plate 8 and the second movable plate 9 are arranged on the top of the first roller 5 and the second roller 6. The first movable plate 8 and the second movable plate 9 have a certain inclination angle compared to the horizontal plane. A first through hole 13 is opened on the top of the box body 1. One end of the inclined first movable plate 8 and the second movable plate 9 are respectively penetrated by the first through hole 13 and extend out of the outside of the box body 1. Since the first movable plate 8 and the second movable plate 9 are relatively inclined, a certain angle is formed between the two, so the first movable plate 8 and the second movable plate 9 extending out of the box body 1 construct a relative clamping space. At the same time, the first movable plate 8 and the second movable plate 9 are respectively provided with second racks 10 on the side facing the first roller 5 and the second roller 6, and the second racks 10 of the first movable plate 8 and the second movable plate 9 are respectively meshed and connected with the gears 7 of the first roller 5 and the second roller 6 to realize further transmission of mechanical kinetic energy, that is, in the vertical movement process of the support rod 3, the first roller 5 and the second roller 6 are first driven to rotate through the cooperation of the first rack 4 and the gear 7, and then the first movable plate 8 and the second movable plate 9 are driven to move through the cooperation of the gear 7 and the second rack 10. Furthermore, the clamping space formed by the cooperation between the top of the first movable plate 8 and the second movable plate 9 also changes accordingly.

[0030] In the present embodiment, an assembly table for clamping and fixing is provided. Through the mechanical linkage and cooperation relationship between the first rack 4, the gear 7 and the second rack 10, in the process of the hydraulic component vertically adjusting the vertical height of the fixed table 16, the clamping space formed by the top of the first movable plate 8 and the second movable plate 9 is synchronously adjusted, so that the functions of clamping and unlocking the radar infrared guidance head are achieved. During the adjustment process, manual operation is no longer required, which greatly improves the efficiency of the assembly operation and ensures the safety of the operation.

[0031] Preferably, the box body 1 is provided with a first limit block 11 and a second limit block 12 at the top of both sides of the opening of the first through hole 13 inside, and the first movable plate 8 and the second movable plate 9 are provided with a limit slide groove on one side relative to the second rack 10, and the size of the limit slide groove matches the size of the first limit block 11 and the second limit block 12, so that the first limit block 11 and the second limit block 12 can be inserted into the limit slide groove of the first movable plate 8 and the second movable plate 9 respectively, and realize the sliding connection between the limit slide grooves. Further, the limiting method of the first movable plate 8 and the second movable plate 9 includes but is not limited to the above-mentioned method, such as a limit slot can be opened inside the first movable plate 8 and the second movable plate 9 along the extension direction of the plate length, and a limit block is respectively provided on the side adjacent to the support rod 3 and the first movable plate 8 and the second movable plate 9, and the limit block is vertically inserted into the limit slot, and during the rotation of the first roller 5 and the second roller 6, the limit block is slidably connected with the limit slot. For another example, the position of the limit block can be set at the top of both sides of the opening of the first through hole 13 outside the box body 1, and the first movable plate 8 and the second movable plate 9 are provided with a limit slot on the side facing the first roller 5 and the second roller 6, and the limit block is inserted into the limit slot to achieve a sliding connection between the limit block and the limit slot. In summary, through the setting of the limit slots of the first limit block 11 and the second limit block 12 and the first movable plate 8 and the second movable plate 9, the moving distance and posture of the first movable plate 8 and the second movable plate 9 are limited, and the stability of the first movable plate 8 and the second movable plate 9 during the movement is improved, and the function of safely clamping and fixing the radar infrared guidance head is achieved.

[0032] Preferably, a first through hole 13 is provided on the top of the support rod 3 to extend out of the outside of the box body 1, and a horizontally placed fixed platform 16 is provided on the top of the support rod 3 for placing the radar infrared guidance head. Under the action of the hydraulic cylinder 2, the support rod 3 realizes vertical extension and contraction, thereby controlling the vertical position movement of the fixed platform 16. During the insertion and placement stage of the radar infrared guidance head, the volume of the clamping space can be further increased to prevent collision between the radar infrared guidance head and the assembly platform.

[0033] Furthermore, the fixed platform 16 includes a placement plate 17 and a buffer box 18. The contact surface between the top of the placement plate 17 and the radar infrared guidance head is designed in an arc surface, which can better fit the surface of the radar infrared guidance head and prevent the radar infrared guidance head from shaking left and right and falling and being damaged. The buffer box 18 is arranged at the bottom of the placement plate 17, and is sleeved and wrapped around the circumferential side wall of the placement plate 17. An accommodating space is formed between the bottom of the placement plate 17 and the inner bottom surface of the buffer box 18. A plurality of sets of elastic members 19 are arranged in the accommodating space, so that during the vertical movement of the support rod 3, if a radar infrared guidance head is placed on the placement plate 17, the elastic member 19 can play a buffering role to prevent the radar infrared guidance head from being damaged by its own inertia and hard extrusion with the placement plate 17. At the same time, rubber pads 20 are pasted on the circumferential side walls of the placement plate 17, and the size of the placement plate 17 matches the size of the buffer box 18, so that the side walls of the placement plate 17 and the inner side walls of the buffer box 18 are abutted against each other through the rubber pads 20, and relative sliding can be achieved. In the process of the support rod 3 driving the fixed platform 16 to move vertically, the relative displacement of the placement plate 17 and the buffer box 18 is more stable and smooth, further ensuring the safety of the placement of the radar infrared guidance head.

[0034] Preferably, the side wall of the box body 1 is provided with a second through hole 14 and a third through hole 15 at the movable path position at the bottom ends of the first movable plate 8 and the second movable plate 9, respectively. When the first movable plate 8 and the second movable plate 9 are retracted into the inside of the box body 1, the first movable plate 8 and the second movable plate 9 will gradually approach the inner side wall of the box body 1. By providing the second through hole 14 and the third through hole 15, the bottom ends of the first movable plate 8 and the second movable plate 9 can be respectively penetrated by the second through hole 14 and the third through hole 15 to extend to the outside of the box body 1. Under the premise of limiting the box body 1 to a smaller volume, the moving distance of the first movable plate 8 and the second movable plate 9 can be extended, thereby making the clamping space formed at the top of the first movable plate 8 and the second movable plate 9 more adjustable.

[0035] Preferably, the top of the first movable plate 8 and the second movable plate 9 are L-shaped toward the fixed platform 16, so that the first movable plate 8 and the second movable plate 9 are arranged parallel to each other on the outside of the box body 1, and clamping plates 21 facing the fixed platform 16 are fixed on the top of the first movable plate 8 and the second movable plate 9, that is, the clamping plate 21 and the top of the first movable plate 8 and the second movable plate 9 are provided with an inclination angle toward the fixed platform 16, and the clamping plates 21 on both sides and the placement plates 17 cooperate to form a ring structure to form a complete clamping space. During the clamping and fixing process of the radar infrared guidance head, the clamping plates 21 on both sides and the placement plates 17 apply force to the radar infrared guidance head from three angles, so that the clamping and fixing are more stable.

[0036] Furthermore, the clamping plate 21 has an arc surface on one side facing the fixing platform 16 and is provided with an anti-slip pad 22, so that the clamping plate 21 and the radar infrared guidance head fit more tightly and firmly.

[0037] Preferably, the first movable plate 8 and the second movable plate 9 are symmetrically staggered on both sides of the support rod 3, so that the relative movement range of the first movable plate 8 and the second movable plate 9 is larger, which helps to make the assembly platform provided in this embodiment applicable to the clamping and fixing operations of radar infrared guidance heads of different sizes, and prevents the first movable plate 8 and the second movable plate 9 as the main components from interfering with each other during the movement, thereby improving the service life of the assembly platform.

[0038] Preferably, a plurality of movable wheels 23 are fixedly provided on the bottom of the outer side of the box body 1. The movable wheels 23 can be brakeable universal wheels to facilitate the movement of the assembly table.

[0039] In an assembly table for clamping and fixing provided in the present embodiment, the meshing cooperation between the rack and the gear 7 realizes the linkage operation of the lifting and lowering of the fixed platform 16 and the contraction and expansion of the clamping plate 21. When the support rod 3 descends, that is, the fixed platform 16 descends, the clamping plates 21 on both sides are unfolded, and the clamping space formed by the clamping plates 21 and the placement plates 17 becomes larger, which is helpful to place the radar infrared guidance head on the fixed platform 16. When the placement is completed, during the rising of the support rod 3, that is, the rising of the fixed platform 16, the clamping plates 21 on both sides are contracted, and the clamping space formed by the clamping plates 21 and the placement plates 17 gradually becomes smaller. Finally, the clamping plates 21 on both sides and the bottom placement plate 17 are both attached to the surface of the radar infrared guidance head to achieve clamping and fixing. During the assembly process of the entire radar infrared guidance head, no manual operation is required, which greatly improves the assembly efficiency. Moreover, a relatively stable triangular structure is formed between the clamping plates 21 on both sides and the placement plates 17, which is helpful to improve the clamping firmness of the radar infrared guidance head.

[0040] At the same time, in an assembly table for clamping and fixing provided in this embodiment, a certain improvement is made to the fixing table 16, and a placement plate 17 and a buffer box 18 are provided. An elastic member 19 is provided between the placement plate 17 and the buffer box 18, so that the fixing table 16 has a certain buffering effect, thereby avoiding the risk of the assembly table body causing damage to the radar infrared guidance head during the assembly process.

[0041] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
