[0031] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] See Figure 2 The slewing support 100 includes an upper cover plate 101, a lower cover plate 102, and a stiffening plate 103 located between the upper cover plate 101 and the lower cover plate 102. A flange 104 is provided in the middle of the upper cover plate 101 and the lower cover plate 102. The flange 104 is located above the upper cover plate 101 and is connected to the upper cover plate 101 and the lower cover plate 102 through a cylinder 105. The four corners of the upper cover plate 101 and the lower cover plate 102 extend outward to form recesses 106 on the sides of the slewing support 100.

[0035] For the aforementioned slewing support 100, please refer to... Figure 1 and Figure 3 This utility model discloses a machining fixture for a rotary support seat, including a base plate 1, a vertical support mechanism 2, and a horizontal support mechanism 3. The base plate 1 has a machining area 11 for placing a rotary support seat 100. The vertical support mechanism 2 is mounted on the base plate 1 and located in the machining area 11, and the vertical support mechanism 2 can move upward to support the rotary support seat 100. The horizontal support mechanism 3 is mounted on the base plate 1 and located around the periphery of the machining area 11, and the horizontal support mechanism 3 can slide horizontally towards or away from the machining area 11 to clamp or release the rotary support seat 100.

[0036] The machining fixture is centrally controlled by a main control system. The base plate 1 is placed horizontally, with its central area serving as the machining area 11 adapted to the rotary support 100. Multiple vertical support mechanisms 2 are provided. Figure 3 For example, four vertical support mechanisms 3 are provided, located at the four corners of the processing area 11, to support the bottom of the rotary support base 100 through lifting and lowering. Multiple horizontal support mechanisms 3 are provided, meaning... Figure 3 For example, the transverse support mechanism 3 has four recesses 106 that correspond to the four recesses 106 of the rotary support seat 100, so as to clamp or release the side of the rotary support seat by sliding.

[0037] It is worth noting that the four vertical support mechanisms 2 are driven to rise or fall synchronously to achieve synchronous and stable support for the bottom of the slewing support base 100. The four horizontal support mechanisms 3 are driven to clamp or release synchronously to achieve the centering, positioning and clamping of the slewing support base 100.

[0038] Therefore, this utility model supports the bottom of the rotary support seat 100 through the vertical support mechanism 2 and clamps the side of the rotary support seat 100 through the horizontal support mechanism 3. Thus, the rotary support seat 100 can be quickly and accurately positioned, centered and clamped through the cooperation of the vertical support mechanism 2 and the horizontal support mechanism 3, and has the characteristics of simple structure and convenient operation.

[0039] See Figure 4 The vertical support mechanism 2 includes a vertical support base 21 and a vertical support rod 22. The vertical support base 21 is fixed to the base plate 1. The vertical support rod 22 extends vertically through the vertical support base 21 and can extend and retract vertically to support the rotary support base 100. The vertical support base 21 is a frame structure to surround and limit the vertical support rod 22. The vertical support base 21 is fixed to the base plate 1 with screws. The vertical support rod 22 can be driven by a hydraulic cylinder to extend and retract vertically to achieve lifting or lowering, thereby abutting against the four bottom corners of the rotary support base 100 to complete the positioning support of the bottom of the rotary support base 100.

[0040] The top of the vertical support rod 22 is provided with a support platform 23, which is used to abut against the bottom of the slewing support 100. The surface area of ​​the support platform 23 is larger than the top surface area of ​​the vertical support rod 22, thereby providing a larger contact area for more stable support of the slewing support 100.

[0041] See Figure 5 The transverse support mechanism 3 includes a transverse support base 31 and a transverse support rod 32. The transverse support rod 32 is fixed to the transverse support base 31. The transverse support base 31 is slidably mounted on the base plate 1 to move closer to or away from the processing area 11, and drives the transverse support rod 32 to clamp or release the rotary support base 100. The transverse support base 31 has a flat plate structure and is horizontally slidably mounted on the base plate 1 to drive the transverse support rod 32 to move closer to or away from the processing area 11. In the clamped state, the side of the transverse support rod 32 abuts against the side wall of the cylinder 105, and the top surface of the transverse support rod 32 abuts against the bottom surface of the flange 104.

[0042] The transverse support rod 32 has a "C"-shaped structure and includes a first horizontal rod 321, a second horizontal rod 322, and a vertical rod 323. The vertical rod 323 is fixed to the transverse support base 31. The first horizontal rod 321 and the second horizontal rod 322 are arranged vertically and spaced apart, facing the processing area 11. The first horizontal rod 321 is used to clamp the rotary support base 100, and the second horizontal rod 322 is used to provide auxiliary support near the bottom of the rotary support base 100. The vertical rod 323 extends vertically and is fixed to the transverse support base 31. The first horizontal rod 321 is fixed to the top of the vertical rod 323. In the clamped state, the side of the first horizontal rod 321 abuts against the side wall of the cylinder 105, and the top surface of the first horizontal rod 321 abuts against the bottom surface of the flange 104. The second horizontal bar 322 is fixed to the lower part of the vertical bar 323. In the clamped state, the second horizontal bar 322 is located at the bottom of the transverse support 100 and slightly lower than the lower cover plate 102, so as to protect the side of the rotary support 100 through the "C"-shaped structure.

[0043] A slide rail 12 is provided on the base plate 1 corresponding to the transverse support seat 31, and a matching slider 33 is provided at the bottom of the transverse support seat 31 corresponding to the slide rail 12. The slider 33 can slide along the slide rail 12 to move closer to or away from the processing area 11. In this way, the cooperation between the slider 33 and the slide rail 12 can improve the smoothness of the sliding of the transverse support seat 31 relative to the base plate 1.

[0044] The slider 33 has protrusions 331 on opposite sides facing the slide rail 12, and the slide rail 12 has corresponding grooves 121. The protrusions 331 are slidably disposed in the corresponding grooves 121. The cooperation between the protrusions 331 and the grooves 121 can improve the tightness of the connection between the slider 33 and the slide rail 12, prevent the slider 33 from falling off the slide rail 12, and thus ensure the smooth sliding of the transverse support 31.

[0045] The transverse support mechanism 3 also includes an auxiliary support member 34, which includes a vertically arranged telescopic rod 341 and a transversely arranged auxiliary rod 342. The telescopic rod 341 is fixed to the transverse support base 31 and can extend and retract vertically. The auxiliary rod 342 is fixed to the telescopic rod 341 and faces the processing area 11 to assist in clamping the rotary support base 100. The telescopic rod 341 is vertically arranged and can be driven to extend and retract vertically by a hydraulic cylinder or the like to raise or lower, thereby causing the auxiliary rod 342 to raise or lower. In the clamped state, the bottom surface of the auxiliary rod 342 abuts against the top surface of the upper cover plate 101, thereby further improving the clamping and positioning effect of the rotary support base 100.

[0046] See Figure 6The transverse support mechanism 3 is driven by a drive mechanism 4 to move closer to or further away from the processing area 11. The drive mechanism 4 includes a hydraulic motor 41, a gear set 42, and a rotating rod 43. The output shaft of the hydraulic motor 41 is connected to the rotating rod 43 via the gear set 42 to drive the rotating rod 43 to rotate. The rotating rod 43 is rotatably mounted on the bottom of the transverse support 31 and the two are threadedly connected. The gear 42 converts the horizontal rotation output by the hydraulic motor 41 into vertical rotation, so that when the rotating rod 43 rotates, the rotation is converted into horizontal movement through the threaded structure, thereby realizing the sliding of the transverse support 31 on the base plate 1.

[0047] The base plate 1 is provided with a receiving groove 13 corresponding to the rotating rod 43, and the rotating rod 43 is rotatably disposed in the receiving groove 13. And / or, the base plate 1 is provided with a limiting plate 14 corresponding to the rotating rod 43, and the rotating rod 43 rotatably passes through the limiting plate 14. The setting of the receiving groove 13 and / or the limiting plate 14 can limit the rotating rod 43 and prevent it from shifting its position, thereby ensuring the clamping effect of the transverse support mechanism 3.

[0048] Based on the above structure, the working process of this machining fixture is as follows: According to the characteristics of the rotary support 100 and the settings of the overall control system, the vertical support mechanism 2 is raised to the designated position, and then the rotary support 100 is hoisted into the machining area 11 and supported by the vertical support mechanism 2. Next, the horizontal support mechanism 3 is driven to slide to abut against the side wall of the cylinder 105, and then the horizontal support mechanism 3 is moved back slightly to loosen the cylinder 105, and then abuts against the side wall of the cylinder 105 again to ensure the abutment effect. Next, the vertical support mechanism 2 is lowered so that the rotary support 100 is lowered until the top surface of the first crossbar 321 abuts against the bottom surface of the flange 104. At the same time, the auxiliary rod 342 is lowered so that its bottom surface abuts against the top surface of the upper cover plate 101. In this way, the positioning, centering and clamping of the rotary support 100 are completed.

[0049] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
