Description

Technical Field

[0001] This application belongs to the technical field of composite material forming, and particularly relates to a general support tooling for composite material forming molds. Background Art

[0002] When forming composite material parts, molds are generally required. During the forming operation, most parts need to be manually laid. Therefore, during the forming process, it is necessary to ensure that the mold has the most suitable operating height for the operator. Since the manufacturing cost of the mold is relatively high, during the forming process, the mold is generally placed on a general support tooling that can adjust the height for operation. In the prior art, the commonly used general support tooling is generally made by using two mutually sleeved square tubes for the support part. The relative position between the two square tubes is adjusted by setting a plurality of limit holes between the two square tubes and connecting different limit holes, so as to achieve the effect of adjusting the general support tooling. However, in this way, it is only convenient to adjust the height when the support tooling is not in use. When the general support tooling is used to support the mold, it is not convenient to adjust the height, because generally the mold is heavy. In the prior art, during the height adjustment of the support tooling, the original connection points need to be disassembled first, and then the limit holes on the two square tubes are adjusted to the required positions and then connected. When disassembling the original connection points, there is no connecting piece for mutual support between the two square tubes. At this time, it is very difficult for the operator to adjust the relative position between the two square tubes under the pressure of the mold weight. Summary of the Utility Model

[0003] This application aims to solve the technical problem that the general support tooling for composite material forming molds in the prior art is not convenient to adjust the support height during use; and provides a general support tooling for composite material forming molds, which can effectively improve the convenience of adjusting the support height of the mold general support tooling during use.

[0004] To achieve the above object, this application adopts the following technical solutions:

[0005] A general support tooling for composite material forming molds includes an upper support frame, a lower support frame, and several connecting rods;

[0006] The upper support frame includes a planar support member and several upper support square tubes. The several upper support square tubes are all fixed on the planar support member. The upper support square tubes are hollow and open at both ends. The upper support square tubes are provided with first limit holes horizontally penetrating through the upper support square tubes;

[0007] The lower support frame includes several lower support square tubes. Several of the lower support square tubes are slidably sleeved with several of the upper support square tubes in a one-to-one correspondence. Several second limiting holes horizontally penetrating through the lower support square tubes are provided on the lower support square tubes. The first limiting hole and one of the second limiting holes are connected by screws or bolts.

[0008] Several of the connecting rods are arranged in the upper support square tubes in a one-to-one correspondence. The connecting rods and the upper support square tubes are connected by a rotating support mechanism. The rotating support mechanism is located above the first limiting hole. The top ends of the connecting rods are located outside the upper support square tubes. The bottom ends of the connecting rods are inserted into the lower support square tubes and are threadedly connected to the lower support square tubes.

[0009] Further, the rotating support mechanism includes an upper ring and a lower ring. The upper ring is fixed to the inner wall of the upper support square tube. The lower ring is fixed to the connecting rod. The lower ring is located below the upper ring. The upper ring and the lower ring are rotatably connected together.

[0010] Further, one or more limiting members are provided on the bottom surface of the upper ring along the circumferential direction of the upper ring. Limiting ring grooves adapted to the limiting members are provided at positions corresponding to the limiting members on the lower ring. The limiting members are rotatably abutted in the limiting ring grooves.

[0011] Further, when there is one limiting member, it is of an annular structure. When there are multiple limiting members, the multiple limiting members are uniformly arranged along the circumferential direction of the upper ring.

[0012] Further, several rotating support balls are provided between the upper ring and the lower ring. A first card slot is provided on the bottom surface of the upper ring. The first card slot is annular along the running direction of the bottom surface of the upper ring. The cross-section of the first card slot is of a circular arc structure. Several second card slots are provided on the top surface of the lower ring. The several second card slots are all of circular arc structures. The several rotating support balls are arranged in the second card slots in a one-to-one correspondence and are rotatably clamped between the first card slot and the second card slot.

[0013] Further, a rotating nut is fixedly provided at a position on the connecting rod outside the upper support square tube.

[0014] Further, an upper cover is detachably connected to the top end of the upper support square tube. The top end of the connecting rod is covered within the upper cover.

[0015] Further, a horizontal reinforcing member is fixedly connected between adjacent two of the lower support square tubes.

[0016] Further, universal wheels are provided at the bottom ends of the lower support square tubes.

[0017] The beneficial effects of this application are as follows:

[0018] In this application, the rotating support mechanism is adopted to connect the upper support square pipe and the connecting rod, enabling relative rotation between the connecting rod and the upper support square pipe. At the same time, the bottom end of the connecting rod is connected to the lower support square pipe by means of screw threading. During use, when it is necessary to adjust the relative position between the upper support square pipe and the lower support square pipe, due to the presence of the connecting rod, even if the connecting screw / bolt between the first limiting hole and the second limiting hole is removed, the relative position between the upper support square pipe and the lower support square pipe will not change. At the same time, during the process of adjusting the height, there is no need for the operator to manually lift the upper support frame. Instead, the upper or lower movement of the upper support square pipe is adjusted by rotating the connecting rod forward or backward. Compared with the previous method of manually lifting or lowering the upper support frame to adjust the relative position between the upper support square pipe and the lower support square pipe, the operation is more convenient, faster, and labor-saving.
