In actual use, it is time-consuming and labor-intensive, affecting processing efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-point support type casting processing positioning device to solve the problems raised in the above background technology in view of the defects of the prior art.

[0005] A multi-point support type casting processing positioning device comprises a base plate and an adjustment part and a support platform which are supported on the base plate in sequence by pillars, the adjustment part is slidably arranged on the pillar, the support platform is fixed to the top end of the pillar, a cylinder is installed on the base plate, and its output end is connected to the bottom groove at the bottom of the adjustment part, the adjustment part is arranged in a truncated cone shape as a whole, a surrounding positioning part is hinged on the support platform, the bottom of the positioning part can slide in the side groove opened on the peripheral side of the adjustment part through rollers, and a support platform is also rotatably installed in the middle of the support platform.

[0006] By adopting the above technical solution, the casting can be quickly positioned, and the positioning of castings of various sizes can be adapted.

[0007] A material collecting plate is installed around the circumference of the support platform, and a material discharging plate is placed on one side of the material collecting plate.

[0008] By adopting the above technical solution, the debris generated by processing can be collected and cleaned conveniently.

[0009] The minimum cross section of the bottom groove at the bottom of the adjusting portion is larger than the cross section of the cylinder body of the cylinder.

[0010] By adopting the above technical solution, when the cylinder pulls down the adjusting part, there is enough space for the adjusting part to descend.

[0011] The support platform is provided with a plurality of groups of notches, and the middle portion of the positioning portion is hinged at the notches.

[0012] By adopting the above technical solution, the positioning part can be adjusted to position the casting.

[0013] The support platform is surrounded by a plurality of through holes.

[0014] By adopting the above technical solution, the through hole can increase the friction of the staff's hand contact, making it more convenient to rotate the support platform.

[0015] The beneficial effects of the multi-point support type casting processing positioning device of the utility model are:

[0016] 1. Place the casting on the support platform, and then drive the cylinder to push the bottom groove upward along the pillar. Because the adjustment part is a truncated cone structure, when the adjustment part moves upward, the position of the roller will be changed, so that the lower ends of the three sets of positioning parts move in the centrifugal direction, and the upper ends of the positioning parts move toward the center of the support platform until the positioning parts fit the edge of the casting and limit the positioning of the edge of the casting. The casting can be quickly positioned and can be adapted to the positioning of castings of multiple sizes;

[0017] 2. The setting of the collecting plate and the discharging plate. During the casting process, the debris generated can fall to the collecting plate for collection, and then the debris can be cleaned out from the discharging plate to reduce the pollution of the working environment by the debris.

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0022] Reference Figure 1-2 A multi-point support type casting processing positioning device, comprising a bottom plate 1 and an adjusting part 3 and a supporting platform 4 which are sequentially supported on the bottom plate 1 by pillars 2, wherein the adjusting part 3 is slidably arranged on the pillars 2, and the supporting platform 4 is fixed to the top end of the pillars 2, and a cylinder 5 is installed on the bottom plate 1, and its output end is connected to the bottom groove 302 at the bottom of the adjusting part 3, and the adjusting part 3 is arranged in a truncated cone structure as a whole, and a surrounding positioning part 6 is hinged on the supporting platform 4, and the bottom of the positioning part 6 can slide in the side groove 301 opened on the peripheral side of the adjusting part 3 through a roller 7, and a support platform 10 is also rotatably installed in the middle of the supporting platform 4;

[0023] Place the casting on the support 10, and then drive the cylinder 5 to push the bottom groove 302 to move upward along the pillar 2. Since the adjusting part 3 is a truncated cone structure as a whole, the position of the roller 7 will be changed when the adjusting part 3 moves upward, so that the lower ends of the three groups of positioning parts 6 move in the centrifugal direction, and the upper ends of the positioning parts 6 move toward the center of the support 10 until the positioning parts 6 fit to the edge of the casting and limit the positioning of the edge of the casting; during the casting processing process, the debris generated can fall to the collecting plate 8 for collection, and the debris can be cleaned up from the discharge plate 9 later.

[0024] A collecting plate 8 is installed around the side of the support platform 10, and a discharge plate 9 is placed on one side of the collecting plate 8; a plurality of through holes are arranged around the support platform 10; when the casting is processed, debris will be generated, and the collecting plate 8 can collect the debris to reduce the debris from polluting the working environment.

[0025] The minimum cross-section of the bottom groove 302 at the bottom of the adjusting part 3 is larger than the cross-section of the cylinder body of the cylinder 5; after the cylinder 5 pulls the adjusting part 3 to move downward along the support 2, the aperture of the bottom groove 302 is larger, and the cylinder body of the cylinder 5 will not affect the normal falling of the adjusting part 3, so that the adjusting part 3 can move up and down normally.

[0026] The support platform 4 is provided with a plurality of notches, and the middle of the positioning portion 6 is hinged at the notches; the width of the notches of the support platform 4 matches the width of the positioning portion 6, and the overall width of the roller 7 matches the width of the side groove 301, so that the devices cooperate with each other more stably.

[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
