Description

Technical Field

[0001] This utility model relates to an auxiliary device for abrasive flow deburring, belonging to the field of cylinder block processing technology. Background Technology

[0002] Abrasive flow deburring equipment can be used to remove burrs from the intersections of oil passages and piston bores in shafts, with significant deburring effects. Cylinder blocks have complex structures, and during machining, burrs easily form at the intersections of the oil passages that power the piston and the inner bore of the cylinder. However, the inner bore of the cylinder is larger than the diameter of the oil passages that connect to it, making it difficult for the abrasive flow to effectively remove the burrs at the intersections. Currently, manual deburring is the only method available, which is inefficient. Furthermore, the difficulty in controlling the force during deburring can easily damage the outer diameter of the cylinder or the inner bore, resulting in defective parts. Summary of the Invention

[0003] This invention addresses the problems of existing technologies by providing an auxiliary device for abrasive flow deburring.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] An auxiliary device for abrasive deburring includes an inner hole positioning assembly and an outer circle positioning assembly. The inner hole positioning assembly includes a positioning shaft, and a positioning platform is provided at the end of the positioning shaft. The diameter of the positioning platform is larger than the diameter of the positioning shaft. A slot is provided on the positioning platform to provide a channel for the flow of abrasive material. A connecting shaft is connected to the side of the positioning platform away from the positioning shaft. The outer circle positioning assembly includes a positioning sleeve and a connecting shaft two provided at the end of the positioning sleeve. The positioning sleeve includes a cylindrical body and an end plate provided at the end of the body. The interior of the body and the end plate are respectively provided with interconnected flow channels two. The end of the connecting shaft two is open, and a flow channel one is provided inside the connecting shaft two. The flow channel one is connected to the flow channel two.

[0006] Furthermore, the positioning platform has an outer end face positioning surface on the side near the positioning shaft, which is used to position the outer end face of the cylinder body; the positioning sleeve has an inner end face positioning surface on the end opposite to the connecting shaft, which is used to position the inner end face of the cylinder body.

[0007] Furthermore, the positioning sleeve is provided with a first hole and a second hole. The diameter of the first hole is larger than the diameter of the second hole. The second hole is located close to the end plate. The first hole and the second hole form an annular platform. The port of the second flow channel is located on the annular platform.

[0008] Furthermore, the second flow channel is provided with multiple channels, and the inner wall of the first flow channel is provided with multiple connecting holes corresponding to the second flow channel.

[0009] Furthermore, the inner wall of the first hole is provided with a groove, and multiple grooves are provided corresponding to the second flow channel.

[0010] Furthermore, the slot is provided in multiple ways.

[0011] Furthermore, the diameter of the positioning shaft is smaller than the diameter of the inner hole of the cylinder.

[0012] Furthermore, the inner diameters of both the first and second holes are larger than the outer diameter of the cylinder body, and the outer diameter of the positioning sleeve is smaller than the inner diameter of the oil passage of the cylinder body.

[0013] Furthermore, the first connecting shaft is used to connect to the abrasive flow equipment, and the second connecting shaft is used to connect to the abrasive flow equipment.

[0014] The beneficial effects of this utility model are as follows: This utility model positions the outer end face and inner end face of the cylinder body through the positioning shaft and positioning sleeve. During grinding, by changing the large space inside the cylinder body into a narrow space, the intersection of the oil passage hole and the inner hole is placed in a narrow space. During the process of abrasive passing through, the flow rate of the abrasive increases and becomes uniform, thereby achieving the removal of burrs at the intersection of the oil passage hole and the inner hole, thereby improving processing efficiency and product qualification rate.

The inner hole positioning assembly 1 includes a positioning shaft 101, and a positioning platform 102 is provided at the end of the positioning shaft 101. The diameter of the positioning platform 102 is larger than the diameter of the positioning shaft 101.

The body 2011 and the end plate 2012 are respectively provided with interconnected flow channels 205. The end of the connecting shaft 206 is open. The connecting shaft 206 is provided with a flow channel 2061, which is connected to the flow channel 205.

[0025] The positioning platform 102 has an outer end face positioning surface 1021 on the side near the positioning shaft 101, which is used to position the outer end face 304 of the cylinder body 3; the positioning sleeve 201 has an inner end face positioning surface 202 on the end opposite to the connecting shaft 206, which is used to position the inner end face 305 of the cylinder body 3.

[0026] The positioning sleeve 201 has a hole 1 203 and a hole 2 204. The diameter of hole 1 203 is larger than the diameter of hole 2 204. Hole 2 204 is located near the end plate 2012. Hole 1 203 and hole 2 204 form an annular platform. The port of flow channel 2 205 is located on the annular platform.

[0027] Multiple flow channels 205 are provided, and multiple connecting holes are provided on the inner wall of flow channel 2061 corresponding to flow channel 205.

[0028] The inner wall of hole 203 is provided with slot 2031, and multiple slots 2031 are provided corresponding to flow channel 205.

[0029] There are multiple slots 104.

[0030] The diameter of the positioning shaft 101 is smaller than the diameter of the inner hole 301 of the cylinder body 3.

[0031] The inner diameters of hole 203 and hole 204 are both larger than the outer diameter of cylinder 3, and the outer diameter of positioning sleeve 201 is smaller than the inner diameter of oil passage 302 of cylinder 3.

[0032] Connecting shaft 103 is used to connect to the abrasive flow equipment, and connecting shaft 206 is used to connect to the abrasive flow equipment.

[0033] See Figure 6 The operation process of this utility model is as follows:

[0034] 1. The connecting shaft 103 of the inner hole positioning component 1 is connected to the abrasive flow equipment. The positioning shaft 101 of the inner hole positioning component 1 is inserted into the inner hole 301 of the cylinder 3. The positioning surface 1021 of the outer end face of the inner hole positioning component 1 is pressed against the outer end face 304 of the cylinder 3 to achieve positioning of the outer end face 304 of the cylinder 3. The positioning shaft 101 of the inner hole positioning component 1 and the inner hole 301 of the cylinder 3 are clearance-fitted to reduce the space inside the inner hole 301 of the cylinder 3.

[0035] 2. The connecting shaft 206 of the outer circle positioning component 2 is connected to the abrasive flow equipment. The positioning sleeve 201 of the outer circle positioning component 2 is fitted into the outer circle of the cylinder body 3. Specifically, the positioning surface 202 of the inner end face of the outer circle positioning component 2 extends into the bottom between the outer circle of the cylinder body 3 and the oil passage 302, and presses against the inner end face 305 of the cylinder body 3 to achieve positioning of the inner end face 305 of the cylinder body 3. At this time, the hole 203 of the outer circle positioning component 2 is located outside the oil passage hole 303. The inner sidewall of the hole 203 and the inner sidewall of the hole 204 respectively have clearance fit with the outer circle of the cylinder body 3 to reduce the space between the outer circle of the cylinder body 3 and the oil passage 302.

[0036] 3. Clamp the cylinder body 3 together with the inner hole positioning component 1 and the outer circle positioning component 2, and start the abrasive flow equipment;

[0037] 4. The abrasive is released by the abrasive flow device. The abrasive flows in from the end opening of the connecting shaft 206 of the outer circle positioning component 2. The abrasive flows through the flow channel 2061 and the flow channel 205 and flows out from the port at the end of the flow channel 205. Since the structure of this utility model reduces the space inside the cylinder 3, the flow rate of the abrasive is accelerated. The abrasive passes through the oil passage 303 between the oil passage 302 and the inner hole 301 of the cylinder 3, which is where the burrs need to be removed, and flows to the inner hole 301 of the cylinder 3. Then it flows from the inner hole 301 of the cylinder 3 to the multiple slots 104 provided on the positioning platform 102 of the inner hole positioning component 1, and then returns to the abrasive flow device, thereby completing the removal of burrs at the intersection of the oil passage 303 and the inner hole 301 of the burr removal cylinder 3.
