DETAILED DESCRIPTION

[0028] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, the multi-process sawing tool of the horizontal sawing machine of this embodiment comprises: a bottom plate 1, on which a slide plate 2 is connected via a linear guide rail pair, and a vertical plate 4 vertical to the slide plate 2 is provided, on which a positioning and clamping assembly is provided for positioning and clamping the casting 8;

[0031] Specifically, the linear guide pair includes a slider and a guide rail matched therewith.

[0032] A limiting mechanism is arranged on the base plate 1, and includes a limiting part and a moving part. The moving part is located on one side of the slide 2. The moving part can move in a straight line, and the stroke is limited by the limiting part. There are multiple limiting parts, so that the moving part forms multiple travel gears; a pushing mechanism, whose output end is connected to the other side of the slide 2, can push the slide 2 to move in the direction of the limiting mechanism until the slide 2 is resisted by the moving part.

[0033] The structure of the limiting mechanism is: it includes a notch plate 19, an axle rod 28 and a stop rod 27. The notch plate 19 is fixed on the base plate 1. A longitudinal through slot 191 is provided on the notch plate 19. A plurality of limit slots 192 are provided at intervals along the length direction of the longitudinal through slot 191. The axle rod 28 serves as a moving part, is passed through the longitudinal through slot 191 and can move along it. A stop head 26 with an enlarged diameter and extending out of the longitudinal through slot 191 is provided at one end of the axle rod 28. The stop rod 27 serves as a limiting part and is vertically arranged at the other end of the axle rod 28. The axle rod 28 can be rotated in the longitudinal through slot 191 by the stop rod 27. The limit slot 192 can accommodate the stop rod 27 to stop the axle rod 28 from moving along the longitudinal through slot 191.

[0034] The pushing mechanism is a cylinder 11 , which is arranged on a cylinder mounting plate 13 , and the cylinder mounting plate 13 is arranged on one side of the base plate 1 .

[0035] An extension rod 21 as an output end is disposed at one end of the push rod of the cylinder 11 , and both ends of the extension rod 21 are respectively threadedly connected to the push rod and the slide plate 2 .

[0036] Specifically, the threaded connection of the extension rod 21 is respectively provided with an external thread or an internal thread. A replaceable extension rod 21 is installed in front of the push rod of the cylinder 11 to fully meet the travel requirements. The extension rod 21 is easy to maintain and replace, and is suitable for strong.

[0037] The structure of the positioning and clamping assembly includes a hollow hole 41 and three groups of clamping assemblies. The three groups of clamping assemblies are distributed in a triangular shape on the outside of the hollow hole 41. Each group of clamping assemblies includes an oil cylinder 3 and a top block 5. The end of the piston rod of the oil cylinder 3 is connected to a movable pressure plate 31. The movable pressure plate 31 and the top block 5 are used to fix the casting 8 from both sides respectively.

[0038] Among them, the three sets of clamping components adopt the principle of three points connected into a plane, which can more firmly press the casting to prevent the casting from shaking during cutting. The corresponding top block 5 is configured on the lower side of the pressing point of the three sets of clamping components. During the pressing process of the casting, the top block 5 can not only play a supporting role, but also play a reverse force, thereby eliminating local deformation of the casting where it is pressed.

[0039] The hollow hole 41 can accommodate the protruding part of the casting, thereby minimizing consumption, reducing the cost of the blank material of the casting, and reducing the transportation weight of the casting.

[0040] The structure of the positioning and clamping assembly also includes a baffle assembly, which includes a fixed plate 6 and an adjustable movable plate 7 corresponding thereto, which are used to cooperate with each other to fix the local structure of the casting 8.

[0041] The accuracy of the casting position during the cutting process affects the amount of final cutting residue. Too much residue affects the processing efficiency of subsequent processing, and too little residue affects the processing accuracy of subsequent processing. This embodiment can ensure the relative position of the casting during placement by positioning the clamping assembly.

[0042] A support plate 20 is provided on the slide plate 2 for supporting the casting 8 from the bottom.

[0043] A top rod 17 is also provided on the vertical plate 4 for contacting with the local structure of the casting 8 and providing support.

[0044] Rib plates 18 are provided on the side of the vertical plate 4 for connecting with the slide plate 2. The rib plates 18 can effectively control the verticality of the casting placement.

[0045] The workflow of this embodiment is as follows:

[0046] The casting 8 is placed in the tooling and cut into three pieces according to the structural characteristics of the product and the requirements for the reuse of waste materials:

[0047] First cut: The stop rod 27 is placed in advance in the limit groove 192 at the position corresponding to the third process of the notch plate 19, the oil cylinder of the positioning clamping assembly presses the casting, the cylinder 11 applies thrust, and the slide plate 2 moves backward until it touches the stopper 26, producing a collision sound. The relative position of the first cut of the casting surface has been determined, and the first cut can be carried out. The first cut mainly removes the filter screen 81 attached to the feed port;

[0048] Second cut: Place the stopper 27 in the limit groove 192 of the notch plate 19 at the position corresponding to the second process. The oil cylinder of the positioning clamping assembly presses the casting. The cylinder 11 applies thrust, and the slide plate 2 moves backward until it touches the stopper 26, producing a collision sound. The relative position of the second cut of the casting surface has been determined, and the second cut can be processed. The second cut mainly removes the excess casting 82 on the first step of the casting. This is pure aluminum material and can be reused after a little processing;

[0049] The third cut: place the stop rod 27 in the limit groove 192 at the position corresponding to the first process of the notch plate 19, the oil cylinder of the positioning clamping assembly presses the casting, the cylinder 11 applies thrust, and the slide plate 2 moves backward until it touches the stop head 26, producing a collision sound. The relative position of the third cut on the casting surface has been determined, and the third cut can be performed. The third cut mainly removes the excess casting 83 on the second step of the casting. This is pure aluminum material and can be reused after a little processing.

[0050] This embodiment realizes the precise positioning of the casting to be cut, by placing the stopper 27 at different limit slots 192 of the notch plate 19, when the slide plate 2 moves to be blocked by the stopper 26, and a collision sound is produced, the positioning of the process is realized. At the same time, the slide plate moves smoothly back and forth in a straight line, so that the cutting surface is flat and the thickness of the residual margin is uniform around.

[0051] Example 2

[0052] See also Figure 3 and Figure 4 Compared with Example 1, the multi-process sawing tool of the horizontal sawing machine in this embodiment further includes a material blocking mechanism, which includes a material blocking plate 10 and a handle 9 arranged on the material blocking plate 10, and the material blocking plate 10 is arranged above the slide plate 2.

[0053] Specifically, the two sides of the bottom of the baffle plate 10 are supported by the support plate 20 and the support rod 14 provided on the cylinder mounting plate 13. The baffle plate 10 covers the bottom plate and the slide plate, which can prevent aluminum chips from remaining on the linear guide rail during the casting cutting process, affecting the normal use of the guide rail. At the same time, it is easy to install and does not occupy the installation position of the overall tooling, so that the overall structure of the tooling is lighter and easier to maintain.
