Description

Technical Field

[0001] The utility model relates to the technical field of cylinder block water jacket core grinding, in particular to a burr removing device for a cylinder block water jacket core. Background Technique

[0002] Removing burrs from the cylinder block water jacket core is an important link in the processing of the engine cylinder block. The existence of burrs will not only affect the appearance quality of the cylinder block, but may also have an adverse impact on the performance and service life of the engine. During the casting or machining process of the cylinder block water jacket core, due to the flow of metal materials, cooling shrinkage, and the cutting action of tools, burrs often occur at the edges or intersections. These burrs vary in size and shape, some are in the form of fine particles, and some form larger protrusions.

[0003] When removing burrs on the inner wall of the cylinder block water jacket core, at present, it is mostly done manually by using tools to teach and remove the burrs on the inner wall of the cylinder block water jacket core. The efficiency of manually removing burrs is low, the labor intensity is high, and it may cause incomplete burr removal or damage to the cylinder block surface due to human factors. And the existing special burr removing equipment can only remove burrs on the inner wall of a single cylinder block water jacket core, and it is difficult to grind the inner walls of multiple cylinder block water jacket cores at the same time. Content of the Utility Model

[0004] The purpose of the utility model is to provide a burr removing device for a cylinder block water jacket core to solve the problems put forward in the above background technique.

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

[0006] A burr removing device for a cylinder block water jacket core, including a burr removing mechanism, and a clamping mechanism is fixedly arranged at the bottom of the burr removing mechanism;

[0007] The burr removing mechanism includes a support seat, a positioning frame is fixedly connected to the top of the support seat, a servo motor is fixedly connected to the top end of the positioning frame, a reciprocating lead screw is fixedly connected to the output end of the servo motor, a driving plate is screwed and sleeved on the outside of the reciprocating lead screw, a lifting plate is fixedly connected to the end of the driving plate, a plurality of rotating shafts are rotatably connected to the lifting plate at equal intervals, a plurality of grinding rollers are fixedly sleeved on the outside of the plurality of rotating shafts, and a plurality of steel brush hairs are fixedly connected to the outer wall of the grinding roller at equal intervals in a ring shape.

[0008] Furthermore, double-groove pulleys are fixedly sleeved at the top ends of the plurality of rotating shafts, a belt is sleeved between adjacent two double-groove pulleys, and the output end of a driving motor is fixedly connected to the top end of one of the rotating shafts.

[0009] Furthermore, two sliding plates are symmetrically and fixedly connected to the side walls of the lifting plate along the length direction, and limiting columns fixedly connected to the top of the support base are slidably sleeved in both of the two sliding plates.

[0010] Furthermore, a polishing disc is slidably sleeved on the outer part of the grinding roller. Four telescopic columns are fixedly connected to the polishing disc at equal intervals in the circumferential direction. The end of the telescopic column is fixedly connected to the end of the grinding roller, and a compression spring fixedly connected to the polishing disc is sleeved on the outer part of the telescopic column.

[0011] Furthermore, the clamping mechanism includes a lifting plate. Fixed arms are fixedly connected to the central positions of the opposite side walls of the lifting plate. One end of a second cylinder is fixedly connected to the inner wall of the fixed arm, the other end of the second cylinder is fixedly connected to a moving plate, and a plurality of arc-shaped clamping plates are fixedly connected to the side wall of the moving plate at equal intervals.

[0012] Furthermore, a rubber pad is fixedly arranged on the inner wall of the arc-shaped clamping plate.

[0013] Furthermore, two first cylinders are symmetrically and fixedly connected to the bottom of the lifting plate with respect to its vertical central plane.

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

[0015] 1. The clamping mechanism can keep multiple cylinder water jacket cores clamped and positioned. Then, the output end of the servo motor drives the reciprocating lead screw to rotate. The reciprocating lead screw can drive the driving plate and the lifting plate to reciprocate up and down in the vertical direction. Since the sliding plates connected to the side walls of the lifting plate are sleeved and slid with the limiting columns, the lifting plate can be limited. At the same time, the driving motor can drive one rotating shaft to rotate. Then, under the synchronous linkage of a plurality of double-groove pulleys and belts, a plurality of rotating shafts can be driven to rotate simultaneously, so that a plurality of grinding rollers can be driven to rotate synchronously. In this way, the lifting plate can drive the plurality of rotating grinding rollers to be inserted into the corresponding cylinder water jacket cores and reciprocate up and down for grinding and polishing. The steel brush hairs arranged on the outer wall of the grinding roller can improve the grinding effect on the inner wall of the cylinder during the reciprocating up and down process of the grinding roller, ensuring that the burrs on the inner wall of the cylinder can be completely removed. Therefore, this device can synchronously remove burrs and grind multiple cylinder water jacket cores, thereby improving the production efficiency of the cylinder water jacket cores.

[0016] 2. During the process of the lifting plate driving the grinding roller to reciprocate up and down, the polishing disc at the top of the grinding roller will contact the end of the cylinder water jacket core. The compression spring provided can make the polishing disc quickly reset, and the grinding roller will drive the polishing disc to polish the end of the cylinder.

[0017] 3. The two cylinders II can push the two moving plates closer to each other, so that the moving plates drive multiple arc-shaped clamping plates to extrude and position the outer wall of the cylinder block water jacket core. Then, the cylinder I can push the lifting plate up to a suitable height for subsequent burr removal processing. The rubber pads provided on the inner walls of the arc-shaped clamping plates can prevent the surface of the cylinder block from being damaged when they contact the outer wall of the cylinder block.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a burr removal device for a cylinder block water jacket core includes a burr removal mechanism 100, and a clamping mechanism 200 is fixedly arranged at the bottom of the burr removal mechanism 100;

[0025] The burr removal mechanism 100 includes a support base 101. A positioning frame 102 is fixedly connected to the top of the support base 101. A servo motor 103 is fixedly connected to the top end of the positioning frame 102. A reciprocating lead screw 104 is fixedly connected to the output end of the servo motor 103. A driving plate 105 is screwed and sleeved on the outside of the reciprocating lead screw 104. A lifting plate 106 is fixedly connected to the end of the driving plate 105. A plurality of rotating shafts 109 are rotatably connected to the lifting plate 106 at equal intervals. Grinding rollers 111 are fixedly sleeved on the outside of the plurality of rotating shafts 109.

A belt 116 is sleeved between two adjacent double-groove pulleys 110. The output end of a driving motor 117 is fixedly connected to the top end of one rotating shaft 109; Two sliding plates 107 are symmetrically and fixedly connected to the side wall of the lifting plate 106 along the length direction. A limiting column 108 fixedly connected to the top of the support base 101 is slidably sleeved in each of the two sliding plates 107.

[0026] Specifically, first, the clamping mechanism 200 can clamp and position a plurality of cylinder water jacket cores. Then, the output end of the servo motor 103 drives the reciprocating lead screw 104 to rotate. The reciprocating lead screw 104 can drive the driving plate 105 and the lifting plate 106 to reciprocate up and down in the vertical direction. Since the sliding plate 107 connected to the side wall of the lifting plate 106 is sleeved and slid with the limiting column 108, the lifting plate 106 can be limited. At the same time, the driving motor 117 can drive one rotating shaft 109 to rotate.

In this way, a plurality of grinding rollers 111 can be driven to rotate synchronously. In this way, the lifting plate 106 can drive the plurality of rotating grinding rollers 111 to be inserted into the corresponding cylinder water jacket cores and reciprocate up and down for grinding and polishing. The steel brush hairs 112 arranged on the outer wall of the grinding roller 111 can improve the grinding effect on the inner wall of the cylinder during the reciprocating up and down process of the grinding roller 111, ensuring that the burrs on the inner wall of the cylinder can be completely removed. Thus, this device can remove burrs and grind a plurality of cylinder water jacket cores synchronously, thereby improving the production efficiency of the cylinder water jacket cores.

The end of the telescopic column 114 is fixedly connected to the end of the grinding roller 111. A compression spring 115 fixedly connected to the polishing disc 113 is sleeved on the outside of the telescopic column 114.

[0029] In this embodiment, during the process of driving the grinding roll 111 to reciprocate up and down by the lifting plate 106, the polishing disc 113 at the top end of the grinding roll 111 will contact the end of the cylinder water jacket core. The extrusion spring 115 can make the polishing disc 113 reset quickly, and the grinding roll 111 will drive the polishing disc 113 to polish the end of the cylinder.

Then, the first cylinder 202 can push the lifting plate 201 to rise to a suitable height for subsequent burr removal processing. The rubber pad 207 arranged on the inner wall of the arc-shaped clamping plate 206 contacts the outer wall of the cylinder to prevent the surface of the cylinder from being damaged.
