Description

Technical Field

[0001] The utility model relates to the technical field of processing of thrust rod brackets, and particularly relates to a machining tool for a thrust rod bracket casting. Background Art

[0002] As an important component for assembling a thrust rod, the thrust rod bracket has a special-shaped structure and is usually formed by casting. Refer to Figure 4 , the existing thrust rod bracket 4 mainly includes a U-shaped main body 41 and two end heads 42. A window 43 is arranged between the two end heads 42 of the U-shaped main body 41. The thrust rod bracket casting obtained by casting needs to be machined, including milling the two side surfaces of the two end heads 42 and surface treatment of the hole walls of the holes on each end head 42, etc.

[0003] In the actual machining process, since the thrust rod bracket has a special-shaped structure and the specifications of different products are different, the wall thicknesses of the vertical parts at both ends of the U-shaped main body 41 are not the same. The use of a fixed-position outer positioning mechanism (i.e., on the outer side of the thrust rod bracket casting) often interferes with the thrust rod bracket casting, and obviously cannot meet the actual positioning requirements. Therefore, for the machining of thrust rod bracket castings with different specifications, how to perform adaptive positioning has become an urgent problem to be solved. Summary of the Invention

[0004] The purpose of the utility model is to overcome the defects and deficiencies existing in the prior art, and provide a machining tool for a thrust rod bracket casting, which can quickly and reliably position thrust rod bracket castings with different specifications adaptively, so as to avoid mutual interference, ensure the machining accuracy, and improve the work efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A machining tool for a thrust rod bracket casting includes a thrust rod bracket casting and a chassis. The thrust rod bracket casting includes a U-shaped main body integrally formed by casting and two end heads. A window is arranged between the two end heads of the U-shaped main body. The characteristic is that: the top surface of the chassis is an inclined plane inclined to one side, and a base is fixedly connected thereto. A positioning component is installed on the base for pressing the U-shaped main body buckled on the base from the upper side and expanding and tightening the U-shaped main body from the inside.

[0007] Furthermore, a column is fixedly connected to the base.

[0008] Further, the positioning member includes a pressing block, two side tightening blocks, a pressure block and a first spring. The pressing block has a trapezoidal structure that is wider at the top and narrower at the bottom, and is slidably sleeved on the column and located between the two side tightening blocks. The two side tightening blocks are provided with inverted V-shaped inclined surfaces on the opposite sides. The pressure block is fixedly sleeved on the column and located above the pressing block. The first spring is sleeved outside the column, and the two ends of the first spring respectively abut against the lower surface of the pressure block and the upper surface of the pressing block.

[0009] Further, one side of the pressure block is provided with a U-shaped slot penetrating through its upper and lower surfaces, and the bottom surfaces at both ends of the pressure block are provided with notches adapted to the edges of the window.

[0010] Further, two guide columns are respectively and fixedly connected to both sides of the column on the base.

[0011] Further, the pressing block is slidably sleeved on the two guide columns, and second springs are sleeved on both guide columns. The two ends of the second spring respectively abut against the lower surface of the pressing block and the upper surface of the base.

[0012] Further, there are at least two bases and positioning members.

[0013] Further, assembly seats are respectively fixedly connected to both sides of the chassis for fixedly installing on the workbench of the machining center.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] See Figures 1-4 , a machining tooling for a thrust rod bracket casting, including a thrust rod bracket casting 4 and a chassis 1. The thrust rod bracket casting 4 includes a U-shaped main body 41 integrally cast and formed and two end heads 42. A window 43 is provided between the two end heads of the U-shaped main body 41. The top surface of the chassis 1 is an inclined surface inclined to one side, and a base 2 is fixedly connected thereto. A positioning member 3 is installed on the base 2 for pressing the U-shaped main body 41 buckled on the base 2 from above and tightening the U-shaped main body 41 from the inside.

[0023] In the present utility model, a column 5 is fixedly connected to the base 2.

[0024] In the present utility model, the positioning member 3 includes a pressing block 31, two side tightening blocks 32, a pressure block 33, and a first spring 34. The pressing block 31 is a trapezoidal structure with a wider upper part and a narrower lower part, slidably sleeved on the column 5 and located between the two side tightening blocks 32. The two side tightening blocks 32 are provided with an inverted V-shaped inclined surface on the opposite side. The pressure block 33 is fixedly sleeved on the column 5 and located above the pressing block 31. The first spring 34 is sleeved outside the column 5, and the two ends of the first spring 34 respectively abut against the lower surface of the pressure block 33 and the upper surface of the pressing block 31.

[0025] Thus, after the thrust rod bracket casting 4, that is, the U-shaped main body 41, is buckled on the base 2, the pressure block 33 is fixedly sleeved on the column 5, so that the pressure block 33 presses the U-shaped main body 41 from above. Under the action of gravity, the pressure block 33 squeezes the first spring 34, and then presses down the pressing block 31, causing it to move downward along the column 5 and pushing the two side tightening blocks 32 to move synchronously to both sides until they abut against the inner walls of the vertical parts at both ends of the U-shaped main body 41, tightening the U-shaped main body 41 from the inside.

[0026] In the present utility model, a U-shaped slot 6 penetrating the upper and lower surfaces is provided on one side of the pressing block 33, facilitating the installation and disassembly of the pressing block 33; on the bottom surfaces at both ends of the pressing block 33, notches 7 adapted to the edges of the window 43 are provided, enabling the pressing block 33 to better press the U-shaped main body 41.

[0027] In the present utility model, two guide posts 8 are respectively and fixedly connected to both sides of the column 5 on the base 2.

[0028] In the present utility model, the extrusion block 31 is slidably sleeved on the two guide posts 8, and second springs 9 are sleeved on both guide posts 8. The two ends of the second spring 9 respectively abut against the lower surface of the extrusion block 31 and the upper surface of the base 2.

[0029] Thus, during the downward movement of the extrusion block 31 along the column 5, the extrusion block 31 synchronously moves downward along the two guide posts 8, playing a guiding role. During this process, the second spring 9 is gradually compressed.

[0030] In the present utility model, there are at least two bases 2 and positioning components 3, enabling at least two thrust rod bracket castings 4 to be processed at one time, effectively improving the working efficiency.

[0031] In the present utility model, assembly seats 10 are respectively fixedly connected to both sides of the chassis 1, realizing the fixed installation of the entire tooling on the workbench of the machining center.

[0032] The following further explains the present utility model with reference to the accompanying drawings:

[0033] During positioning, first, the thrust rod bracket casting 4, i.e., the U-shaped main body 41, is placed upside down on the base 2, and then the pressing block 33 is fixedly sleeved on the column 5, enabling the pressing block 33 to press the U-shaped main body 41 from above. Under the action of gravity, the pressing block 33 squeezes the first spring 34, further pressing down the extrusion block 31, causing it to move downward along the column 5 and the two guide posts 8, pushing the two tensioning blocks 32 on both sides to move synchronously towards both sides until they abut against the inner walls of the vertical parts at both ends of the U-shaped main body 41, tightening the U-shaped main body 41 from the inside.

[0034] After positioning, start the tools for milling and hole machining of the machining center, move horizontally (i.e., parallel to the direction of the machining workbench), perform milling on the two side surfaces of the two ends 42, and perform surface treatment on the hole walls of the through holes on the two ends 42.

[0035] It should be noted that since the two tensioning blocks 32 move synchronously towards both sides, tightening the U-shaped main body 41 from the inside, the relative position between the center of the U-shaped main body 41 and the center of the base 2 remains unchanged. Furthermore, the positions of the two ends 42 to be processed relative to the base 2 remain unchanged without deviation, ensuring the machining accuracy.

[0036] In addition, since there are at least two base parts 2 and positioning parts 3, at least two thrust rod bracket castings 4 can be positioned at one time. Furthermore, at least two thrust rod bracket castings 4 can be machined at one time, thereby effectively improving the working efficiency.

[0037] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0038] Therefore, the above description is only the preferred embodiment of the present application and is not used to limit the scope of implementation of the present application; that is, all equivalent transformations made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
