Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a milling and drilling fixture for profile steel. Background Technology

[0002] Forklifts, as crucial equipment in logistics systems, are the mainstay of material handling equipment. They are widely used in various locations across the national economy, including railway stations, ports, airports, factories, and warehouses. Currently, most enterprises have moved away from manual material handling, replacing it with mechanized handling primarily using forklifts. Therefore, the demand for forklifts has grown rapidly annually in recent years. The forklift crossbeam is a beam installed transversely along the mast in the forklift's internal and external mast structure and supported on the main load-bearing components; it is perpendicular to the mast and serves to bear and distribute the stress on the main mast beam. Based on the structure and working principle of the forklift lifting system, the forklift crossbeam is the skeleton that bears the lifting operation; its rigidity, strength, and stability directly affect the overall safety performance of the vehicle. Figure 1 The S-shaped forklift beam shown is made of hot-rolled steel. During the processing, the hot-rolled steel of a single length needs to be notched and drilled. Usually, a milling machine is used to notch the steel first, and then a drilling machine is used to drill the steel. The processing efficiency is low, and the position and dimensional accuracy of the notch and the drilled hole are not easy to guarantee. Utility Model Content

[0003] This utility model provides a milling and drilling fixture for profile steel to solve the technical problem that in the existing processing of S-shaped forklift crossbeams, it is necessary to first use a milling machine to mill the notch and then use a drilling machine to drill the hole, which results in low processing efficiency and difficulty in ensuring the positional and dimensional accuracy of the notch and the hole.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A milling and drilling fixture for profile steel includes a fixture base plate, on which at least one set of support plates are provided, each set of support plates being arranged in a straight line; a side baffle is provided on one side of each support plate, and a side pressure cylinder is provided on the other side; an end baffle and an alignment cylinder are respectively provided at both ends of each set of support plates, the end baffle and the alignment cylinder being arranged opposite to each other.

[0006] Optionally, a set of support plates is provided on the base plate of the fixture, and the cross-section of the side baffle is L-shaped.

[0007] The side pressure cylinder is provided with a side pressure cylinder connector at the end facing the side baffle.

[0008] The alignment cylinder is provided with an alignment cylinder pressure head at one end facing the end baffle.

[0009] A guide is provided between two adjacent side-pressure cylinders.

[0010] The fixture base plate is also provided with eye bolts, which are distributed at diagonal positions on the fixture base plate.

[0011] A key block is provided between the side pressure cylinder and the fixture base plate, and a alignment cylinder pad is provided at the bottom of the alignment cylinder.

[0012] The side baffle is fixedly connected to the fixture base plate by an internally threaded cylindrical pin.

[0013] Optionally, the fixture base plate is provided with two sets of support plates, which are arranged in parallel. The side baffle is located between the two sets of support plates, and the cross-section of the side baffle is U-shaped.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] In the above solution, the steel milling and drilling fixture can clamp multiple forklift crossbeam steel sections at one time, thereby realizing the simultaneous processing of notches and holes on multiple forklift crossbeam steel sections, which has high processing efficiency and high dimensional accuracy.

[0043] like Figures 2-5 As shown, this utility model provides a milling and drilling fixture for steel profiles, including a fixture base plate 2. At least one set of support plates 5 are provided on the fixture base plate 2. The support plates 5 are used to support the crossbeam steel of a forklift. Each set of support plates 5 is arranged in a straight line along the axial direction of the crossbeam steel of the forklift. A side baffle 3 is provided on one side of the support plate 5, and a side pressure cylinder 11 is provided on the other side. An end baffle 4 and a centering cylinder 12 are respectively provided at both ends of each set of support plates 5. The end baffle 4 and the centering cylinder 12 are arranged opposite to each other.

[0044] like Figures 2 to 4 As shown, in this embodiment, a set of support plates 5 are provided on the clamp base plate 2, and the side baffle 3 has an L-shaped cross section with a vertical wall on the side near the support plate 5. During clamping, two forklift crossbeams are placed together on the support plate 5 and positioned opposite each other. The vertical wall of the side baffle 3 can position the side of the adjacent forklift crossbeam. The side pressure cylinder 11 is provided with a side pressure cylinder connector 8 at one end facing the side baffle 3. The side pressure cylinder 11 is used to press the other forklift crossbeam.
