Description

Technical Field

[0001] The present invention relates to the technical field of floor covering blanking, and more particularly to a floor covering blanking tooling. Background Art

[0002] The existing floor covering blanking process is completed on the sub-assembly platform in the general assembly workshop. The blanking steps basically involve selecting different floor coverings according to different vehicle models. First, the floor covering is cut, and then the cut floor covering is sent into the vehicle for installation. One of the common specifications is a floor covering with a length and width of 80m×2m, and the weight is 300kg. Such a heavy floor covering cannot be lifted by one person at all. Each time floor covering blanking requires the assistance of 4 people. One person first forks it onto the sub-assembly platform with a forklift, 2 people spread out the rolled floor covering, and 1 person cuts the length of the floor covering as needed. This cutting method has poor accuracy, wastes both working hours and materials. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects of the above-mentioned existing technologies and provide a floor covering blanking tooling.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and the detailed implementation mode and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0030] Embodiment

[0031] As Figure 1 、 2 shown, the present application provides a floor leather cutting tooling, including: a skeleton assembly 1 including a floor leather unwinding rack, a rotating shaft assembly 2 for installing the floor leather 6, a crank assembly 3 for rotating the rotating shaft assembly 2, and a cutting platform 4 for laying the floor leather 6. A measuring scale 5 for measuring the positioning dimensions of the floor leather 6 is provided on the cutting platform 4.

[0032] As Figure 3 shown, the skeleton assembly 1 includes a floor leather unwinding rack with a slope at the top, and a plurality of first placing brackets arranged at intervals are provided at the top of the floor leather unwinding rack. The rotating shaft assembly 2 includes a plurality of... respectively arranged on the first placing brackets and sleeved with the floor leather 6 coil. As Figure 4 shown, the floor leather unwinding rack is a frame structure with a right trapezoidal cross-section shape formed by connecting a plurality of inclined pipes and straight pipes. Vertical support rods 9 are provided on two side elevations of the frame structure, and diagonal rods 13 for increasing strength are provided on the rear elevation of the frame structure. The first placing brackets include two struts 12 symmetrically arranged on both sides of the top of the floor leather unwinding rack and extending obliquely upward.

[0033] A second placing bracket is provided on the front side corresponding to the lower part of each first placing bracket in the floor leather unwinding rack, and a roller shaft 20 for guiding the floor leather 6 to unwind is provided at each second placing bracket. The second placing bracket includes a reinforcing rod 10 connected between two vertical support rods 9 and a fixed rod 11 arranged on the upper side of the reinforcing rod 10, and the roller shaft 20 is arranged between the reinforcing rod 10 and the fixed rod 11. After the floor leather 6 is pulled down from the rolled state, it is conveyed to the cutting platform 4 along the roller shaft 20 obliquely downward. Since the floor leather 6 is pulled relatively tightly, the roller shaft 20 can play a role in supporting and conveying the floor leather 6.

[0034] Figure 5 , 6 As shown, it is a rotating shaft assembly. The rotating shaft assembly 2 includes a rotating rod 7 and rotating ends 8 rotatably arranged on both sides of the rotating rod 7. The rotating rod 7 includes a shaft tube 25 and shaft heads 24 arranged on both sides of the shaft tube 25. The structure of the rotating end 8 is as Figure 6 shown, including a shaft connected to the shaft head 24, on which a bearing 22 and a shaft sleeve 23 are provided, and an outermost bearing sleeve 21 is sleeved. The rotating end 8 is placed on the first placement bracket.

[0035] As Figure 7 shown, the crank handle assembly 3 includes a crank handle connecting rod 16, and crank handle joints 15 and crank handle grips 17 with opposite extending directions are respectively provided at both ends of the crank handle connecting rod 16. A crank handle grip sleeve 18 is sleeved on the outer side of the crank handle grip 17, and a crank handle grip limit sleeve 19 is provided at the outer end of the crank handle grip 17 facing outward. A crank handle interface 14 is provided on the rotating end 8 of the rotating shaft assembly, and the crank handle joint 15 is fixed in the crank handle interface 14.

[0036] One crank handle assembly 3 is provided on one side of the rotating shaft assembly 2 on each first placement bracket. The blanking platform 4 is arranged on the ground in front of the skeleton assembly 1. The employee uses the crank handle assembly 3 to rotate the rotating shaft assembly 2, and the floor leather 6 is led down from the skeleton assembly 1 to the blanking platform 4. Guided by the dimensions of the measuring scale 5 on the blanking platform 4, the floor leather 6 is spread forward. When the requirements of the drawing blanking dimensions are met, the forward movement is stopped, and the floor leather 6 is cut with a knife. According to the principle of the uncoiling line, the feeding, feeding, dimension measurement, and cutting of the floor leather 6 are completed in one go, greatly improving the production efficiency.

[0037] In this embodiment, 3 first placement racks are provided, and three types of floor leather 6 can be stored simultaneously through the rotating shaft assembly 2. When using the floor leather 6 blanking tooling, first install the three types of floor leather 6 on the rotating shaft assembly 2 respectively, and then hoist the rotating shaft assembly 2 to the skeleton assembly 1. In this way, the floor leather 6 can be switched at any time according to the needs of the vehicle type, without the need for frequent handling of the floor leather 6 or waiting. For the blanking of the floor leather 6 of 1 vehicle in the prior art, it takes 4 people 20 minutes to complete. While using this tooling, the blanking of the floor leather 6 of 1 vehicle only takes 1 person 10 minutes to complete. The number of people is reduced by 3, and the efficiency is increased by about 2 times. Moreover, the blanking of the floor leather 6 is quite convenient, further increasing the production capacity of the assembly line.

[0038] For a mature series of vehicle models, a set of tooling is also preferably used for production as much as possible. This can greatly save the tooling replacement time and the tooling storage space. A set of tooling adopts a general design, reducing adverse factors such as deformation, inconvenient transportation, and excessive storage space caused by the too large tooling.
