Description

Technical Field

[0001] The utility model relates to the technical field of wire pushing devices, in particular to an improved diamond wire pushing device. Background Art

[0002] Diamond wire is the abbreviation of diamond cutting wire, also known as diamond cutting wire or diamond wire. Diamond wire is commonly used in cutting equipment, and is widely used in traditional bridge cutting machines. When the cutting machine uses diamond wire, it is necessary to use a wire-jacking device to tighten the diamond wire on each transmission wheel, so that the transmission wheel can drive the diamond wire to cut the stone when it rotates.

[0003] like Figure 1 As shown, the wire-pushing device in the prior art includes a main frame 1', two triangle plates 3' which are rotatably arranged on the main frame 1' through a rotating shaft 2' at the left end and are arranged opposite to each other, a wire-pushing wheel 4' arranged at the right end of each triangle plate 3', and a driving cylinder 5' whose fixed end is arranged on the main frame 1' and whose output end is hingedly connected to the lower end of the triangle plate 3' and is used to drive the triangle plate 3' to rotate upward around the rotating shaft 2' so that the wire-pushing wheel 4' presses the diamond wire tightly. When the diamond wire needs to be pressed tightly, the lower end of the triangle plate is pushed simultaneously by the two driving cylinders to rotate upward around the rotating shaft, so that the diamond wire is pushed upward by the wire-pushing wheel to press the diamond wire tightly on each rotating wheel.

[0004] Although the wire-pushing device in the prior art can tighten the diamond wire, when tightening a long diamond wire, it is necessary to drive the triangle plate to rotate upward around the rotating axis with a large amplitude, and the driving amplitude of the driving cylinder on the triangle plate is limited, which may easily lead to the failure of the wire-pushing wheel to completely tighten the diamond wire, thereby causing the diamond wire to be unable to be tensioned on each rotating wheel, affecting the cutting of the stone by the diamond wire. Utility Model Content

[0005] The utility model aims to provide an improved diamond wire top wire device in view of the defects and shortcomings of the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an improved diamond wire top wire device, comprising a main frame, and also comprising two support plates symmetrically arranged on the left and right sides of the main frame, two mounting seats respectively arranged at the front and rear ends of the two support plates and symmetrically arranged, a mounting frame arranged between the two mounting seats, located above the support plates and having an opening, a fixed end arranged on the mounting frame, an output end close to the end of the main frame and equidistantly arranged, and used to drive the output end to move closer to or away from the end of the main frame, a connecting support plate arranged on the output end of each of the telescopic cylinders, and a top wire wheel rotatably arranged on the connecting support plate for tightening or loosening the diamond wire when the output end of the telescopic cylinder moves closer to or away from the end of the main frame.

[0007] A further improvement is that an auxiliary support member is provided between each telescopic cylinder and the mounting frame and connected to the connecting support plate, which is used to improve the stability of the connecting support plate and prevent the connecting support plate from shaking when the telescopic cylinder drives the output end to approach the end of the main frame so that the top wire wheel tightens the diamond wire.

[0008] A further improvement is that the auxiliary support member includes two fixed blocks arranged between the upper and lower ends of each telescopic cylinder and the mounting frame, sliding openings respectively penetrating the two fixed blocks, and two matching support rods respectively slidably arranged on the fixed blocks in the sliding openings and connected to the connecting support plate at one end.

[0009] A further improvement is that one end of the matching support rod is detachably arranged on the connecting support plate through a support rod bolt, and the two fixing blocks are detachably arranged on the telescopic cylinder through cylinder bolts.

[0010] A further improvement is that the upper and lower ends of the two fixing blocks are connected to the installation frame by fixing bolts.

[0011] A further improvement is that the front and rear ends of the mounting frame are rotatably connected to the two mounting seats via a rotating shaft, and the two mounting seats are provided with rotating bearings for cooperating with the rotating shaft. A driving mechanism is provided between one of the support plates and the rotating shaft, which is used to drive the rotating shaft to drive the mounting frame to rotate between the two mounting seats to adjust the inclination angle of the telescopic cylinder when starting, and to fix the rotating shaft on the mounting seat when closing to prevent the rotating shaft from rotating.

[0012] A further improvement is that the driving mechanism includes a turbine reducer whose fixed end is arranged on one of the support plates and connected to the rotating shaft, the turbine end of the turbine reducer is connected to the rotating shaft, and a driving handle is arranged on the turbine reducer, and the driving handle is connected to the worm end of the turbine reducer.

[0013] A further improvement is that a connecting hole is provided at the center end of the top line wheel, a connecting spindle is provided in the connecting hole, a line wheel bearing is provided in the connecting hole between the connecting spindle and the top line wheel, and the front and rear ends of the connecting spindle are detachably provided on the connecting support plate by line wheel bolts.

[0014] A further improvement is that a wear-resistant rubber ring is arranged on the outer peripheral side of the top line wheel, and the wear-resistant rubber ring is a polyurethane rubber ring.

[0015] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: when it is necessary to tighten the diamond wire of a longer length, the output end is driven by the telescopic cylinder to drive the connecting support plate closer to the end of the main frame, so that the wire-pushing wheel can completely tighten the diamond wire, thereby making the diamond wire tensioned on each rotating wheel, which will not affect the cutting of the stone by the diamond wire.

[0016] Further effect: when the output end of the telescopic cylinder drives the connecting support plate toward the end of the main frame, the matching support rod slides in the sliding opening along with the output end of the telescopic cylinder. When the top line wheel tightens the diamond wire, the connection between the two matching support rods and the connecting support plate can improve the stability of the connecting support plate and further prevent shaking during top line.

[0017] Further effect: the rotating shaft is driven to rotate by the driving mechanism, thereby changing the inclination angle of the telescopic cylinder on the mounting frame, and the tensioning force and the tensioning angle can be further adjusted according to customer needs.
