Paving machines are composed of large and small parts, and parts such as connecting plates usually have different angles of profiling. The traditional processing method uses a specific processing device or processing mold for processing, which leads to a significant increase in the purchase cost of the device or mold, and increases the production cost. In order to improve this situation, the present invention proposes an adjustment and locking mechanism for the profiling angle of parts on a paving machine, which can be used for profiling at different angles, has a wide applicability, can meet the angle profiling processing of different parts, and greatly reduces the processing cost of parts. [Summary of the invention]

[0004] To achieve the above-mentioned purpose, the present invention proposes an adjustment and locking mechanism for the pressure angle of parts on a road paving machine, comprising a fixed platform, a mold block, a cushion block, a threaded adjustment column and a locking structure. The mold block is placed on the fixed platform, and slide grooves are provided on the front and rear sides of the fixed platform. Several groups of locking structures are installed on the slide grooves. The locking structure is cooperatively connected with the threaded adjustment column. A hand wheel is installed at the outer end of the threaded adjustment column, and the inner end abuts against the side of the mold block through the cushion block.

[0006] Preferably, the locking structure is composed of a connecting bolt, an inner locking nut, an outer locking nut, a gasket, and a high-strength connecting plate. Bolt connecting holes and adjusting column connecting holes are respectively provided at both ends of the high-strength connecting plate. The connecting bolt is installed in the slide groove and can move in the slide groove. The stud end of the connecting bolt passes through the bolt connecting hole and the gasket of the high-strength connecting plate in sequence and is fixedly connected with the inner locking nut and the outer locking nut. The inner end of the threaded adjustment column passes through the adjusting column connecting hole of the high-strength connecting plate and abuts against the outer section of the gasket.

[0007] Preferably, the outer circumference of the threaded adjustment column has an adjusting external thread, the threaded adjustment column is threadedly connected to the adjustment column connecting hole, and the bolt connecting hole is a through hole without thread.

[0008] Preferably, the cross-section of the slide groove is in a horizontal "convex" shape, and the opening of the slide groove faces outward, and the head end of the connecting bolt abuts against the slide groove.

[Specific implementation method]

[0017] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of the present invention. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0018] See also Figure 1 The embodiment of the present invention provides an adjustment and locking mechanism for the pressure angle of parts on a road paver, comprising a fixed platform 1, a mold block 2, a cushion block 3, a threaded adjustment column 4 and a locking structure 5. The mold block 2 is placed on the fixed platform 1. The front and rear sides of the fixed platform 1 are provided with slide grooves 11. Several groups of locking structures 5 are installed on the slide grooves 11. The locking structure 5 is connected with the threaded adjustment column 4. The outer end of the threaded adjustment column 4 is provided with a hand wheel 41, and the inner end is abutted against the side of the mold block 2 through the cushion block 3.

[0019] Furthermore, the mold block 2 is a regular quadrangular prism structure, and a plurality of right-angle grooves 21 with different side lengths are provided on each side of the mold block 2, and the openings of the right-angle grooves 21 are all facing outwards.

[0020] In the embodiment of the present invention, according to the size of the pressing angle of the part to be processed, the right-angle groove 21 that meets the requirements on the mold block 2 can be selected to face upward. The right-angle grooves 21 with different side lengths are integrated on the same mold block 2. It has a wide applicability and can be used for processing without pressing the angle. It can also greatly reduce the purchase cost of the device and the mold and reduce the production cost.

[0021] Furthermore, the locking structure 5 is composed of a connecting bolt 51, an inner locking nut 52, an outer locking nut 53, a gasket 54, and a high-strength connecting plate 55. The two ends of the high-strength connecting plate 55 are respectively provided with a bolt connection hole 56 and an adjustment column connection hole 57. The connecting bolt 51 is installed in the slide groove 11 and can move in the slide groove 11. Figure 2 The stud end of the connecting bolt 51 passes through the bolt connection hole 56 and the gasket 54 of the high-strength connecting plate 55 in sequence and is fixedly connected with the inner locking nut 52 and the outer locking nut 53. The inner end of the threaded adjustment column 4 passes through the adjustment column connection hole 57 of the high-strength connecting plate 55 and abuts against the outer section of the cushion block 3.

[0022] In the embodiment of the present invention, there are four groups of locking structures 5, two groups of locking structures 5 are installed on each slide slot 11, and the locking structures 5 on different slide slots 11 are symmetrically arranged. The symmetrically arranged locking structures 5 improve the clamping strength and avoid the problem of large profiling deviation caused by skewness.

[0023] Furthermore, the outer periphery of the threaded adjustment column 4 has an adjusting external thread, the threaded adjustment column 4 is threadedly connected to the adjustment column connecting hole 57, the bolt connecting hole 56 is a through hole without threads, the cross-section of the slide groove 11 is a horizontal "convex" shape, and the opening of the slide groove 11 faces outward, and the head end of the connecting bolt 51 abuts against the slide groove 11.

[0024] Furthermore, the height of the cushion block 3 is slightly smaller than the height of the mold block 2, and the cushion block 3 is connected to the mold block 2 through a plane, and the outer periphery of the hand wheel 41 has an anti-skid groove. By adding the cushion block 3 between the mold block 2 and the threaded adjustment column 4, the clamping area is increased, the force is evenly distributed, and the clamping effect is improved. The anti-skid groove on the hand wheel 41 improves the anti-skid effect when the hand wheel 41 is turned.

[0025] The present invention discloses an adjusting and locking mechanism for the pressure angle of parts on a road paver. The mechanism has a reasonable structure and is assembled by a fixed platform 1, a mold block 2, a cushion block 3, a threaded adjustment column 4 and a locking structure 5. The mold block 2 can move on the fixed platform 1, and the mold block 2 is provided with a right-angle groove 21 with different side lengths on each side. During actual processing, it is only necessary to flip the right-angle groove 21 on the mold block 2 that meets the pressure angle of the part upward, and then tighten and fix it through the cushion block 3, the threaded adjustment column 4 and the locking structure 5. The position of the mold block 2 on the fixed platform 1 can be adjusted by rotating the threaded adjustment column 4. The mold block 2 has the effects of adjustable position and variable angle of the right-angle groove 21, which can meet the pressure angle processing of different angles, avoids the need to purchase a large number of processing equipment and molds, and reduces production costs.
