Description

Technical Field

[0001] This utility model relates to the field of automotive oil pipe processing technology, and in particular to a device for removing burrs from the inner bore of automotive oil pipes. Background Technology

[0002] In the automobile manufacturing process, oil pipes are important components for transporting oil. The smoothness of their inner holes has a direct impact on oil flow and engine performance. Therefore, after the oil pipes are manufactured, a burr removal process is required to ensure the smoothness of their inner holes.

[0003] For example, Chinese utility model patent CN218371047U discloses a "tool for removing burrs from the inner hole of an automotive oil pipe". This device includes an oil pipe, a positioning element, and a support plate. The surface of the oil pipe is in close contact with the inner wall of the positioning element, the bottom of the positioning element is slidably connected to the inside of the support plate, and a mating block is fixedly connected to the front side of the positioning element. This utility model, by setting up an oil pipe, a positioning element, a support plate, a mating block, a locking device, and a deburring device, allows the positioning element to clamp and fix the oil pipe. The locking device, in conjunction with the mating block, solves the problem of existing methods where users manually rotate a deburring brush inside the inner hole of the automotive oil pipe, which is too labor-intensive and cannot automatically rotate the brush to remove burrs.

[0004] However, since the above-mentioned device can only remove burrs from oil pipes of one specification, the removal of burrs will fail if the diameter of the oil pipe is too small or too large, which limits the scope of application and makes the device not very practical. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a burr removal device for the inner bore of automotive oil pipes. It solves the problem that traditional burr removal equipment can only remove burrs from oil pipes of one specification, resulting in a limited range of applications and low practicality.

[0007] Compared with the prior art, this utility model has the following beneficial effects: With the setting of the adjustment component, the relative positions of multiple sets of burr brushes can be adjusted, changing the diameter formed by the cooperation of multiple sets of burr brushes to adapt to oil pipes of different diameters for cleaning their interiors. The multiple sets of burr brushes are adjusted according to the diameter of the oil pipe, and then the spiral shaft is driven to move up and down reciprocally through the sliding groove connecting rod. During the up and down reciprocating motion of the spiral shaft, it is threadedly connected to the drive seat, so that the spiral shaft rotates while moving up and down, causing the burr brushes to rotate while moving up and down inside the oil pipe, cleaning its inner wall. The cleaned burr residue falls into the collection box for centralized treatment.

[0008] Preferably, the adjusting component includes a movable ring, an adjusting nut, multiple sets of mounting arms, and two sets of fixed rings fixedly disposed at one end of the spiral shaft. Multiple sets of first connecting arms are evenly distributed on one set of fixed rings, and multiple sets of second connecting arms are evenly distributed on the other set of fixed rings.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a burr removal device for the inner hole of an automotive oil pipe, which includes a collection box 1, a mounting plate 101 fixedly disposed on one side, and a drive seat 102 disposed at the end of the mounting plate 101 away from the collection box 1; a cleaning device, including a spiral shaft 2 threadedly connected to the drive seat 102 and a cleaning component disposed at one end of the spiral shaft 2, the cleaning component including multiple sets of burr brushes 3 and an adjusting component for adjusting the multiple sets of burr brushes 3, the burr brushes 3 being used to clean the oil pipe body 100; a driving device, including a sliding groove connecting rod 203 rotatably disposed on one side of the mounting plate 101, and an L-shaped arm 201 rotatably connected to the sliding groove connecting rod 203, one end of the L-shaped arm 201 being rotatably connected to one end of the spiral shaft 2, the sliding groove connecting rod 203 being used to drive the spiral shaft 2 to reciprocate up and down; and a clamping assembly disposed in the collection box 1 for clamping the oil pipe body 100.

[0022] The detailed working process of this embodiment is as follows: With the adjustment component set, the relative positions of multiple sets of burr brushes 3 can be adjusted to change the diameter formed by the cooperation of multiple sets of burr brushes 3 to adapt to oil pipes of different diameters for cleaning their interiors. The multiple sets of burr brushes 3 are adjusted according to the diameter of the oil pipe, and then the spiral shaft 2 is driven to move up and down reciprocally through the sliding groove connecting rod 203. During the up and down reciprocating motion of the spiral shaft 2, it is threadedly connected to the drive seat 102, so that the spiral shaft 2 rotates while moving up and down, so that the burr brushes 3 rotate while moving up and down inside the oil pipe to clean its inner wall. The cleaned burr residue falls into the collection box 1 for centralized processing.

[0023] like Figure 2 and Figure 3As shown, the adjusting component includes a movable ring 206, an adjusting nut 5, multiple sets of mounting arms 302, and two sets of fixed rings 205 fixedly disposed at one end of the spiral shaft 2. Multiple sets of first connecting arms 304 are evenly distributed on one set of fixed rings 205, and multiple sets of second connecting arms 305 are evenly distributed on the other set of fixed rings 205. The first connecting arms 304 and second connecting arms 305 correspond one-to-one. Each first connecting arm 304 and each second connecting arm 305 are respectively hinged to both ends of the corresponding mounting arm 302. A third connecting arm 306 is hinged to one end of each mounting arm 302 near the second connecting arm 305. Each third connecting arm 306 is hinged to the movable ring 206. The adjusting nut 5 includes a cylindrical portion 501 and a screw portion 502. The cylindrical portion 501 is rotatably connected to the movable ring 206, and the screw portion 502 is threadedly connected to the spiral shaft 2.

[0024] like Figure 3 As shown, each mounting arm 302 is provided with a T-slot 303, and multiple sets of burr brushes 3 can be detachably installed in the corresponding T-slot 303.

[0025] The detailed working process of this embodiment is as follows: The burr brushes 3 are detachably installed in the corresponding T-slots 303, which facilitates the replacement of the burr brushes 3. The first connecting arm 304 and the second connecting arm 305 can rotate along the hinge point on the corresponding fixing ring 205 and the mounting arm 302. It is necessary to change the relative distance between each burr brush 3 and the spiral shaft 2. When the burr brush 3 is close to the spiral shaft 2, the diameter formed by the interaction of each burr brush 3 decreases, and vice versa. During adjustment, simply rotate the adjusting nut 5 to drive the movable ring 206 close to the end of the spiral shaft 2 to change the size of the diameter formed by the interaction of each burr brush 3. When the movable ring 206 is close to the extreme position of the spiral shaft 2, the diameter formed by the interaction of each burr brush 3 is the largest. When the movable ring 206 is far away from the extreme position of the spiral shaft 2, the diameter formed by the interaction of each burr brush 3 is the smallest. The adjusting nut 5 also limits the movement while adjusting, so as to prevent the burr brushes 3 from being forced close to the spiral shaft 2 during the cleaning process, thus changing the size of the diameter formed by the interaction of each burr brush 3.

[0026] like Figure 2 As shown, a drive block 204 is fixedly installed at one end of the L-shaped arm 201, and the drive block 204 abuts against the slide rail connecting rod 203.

[0027] The detailed working process of this embodiment is as follows: the drive block 204 is engaged in the groove on the sliding rod 203. When the sliding rod 203 rotates, the drive block 204 slides in the groove, and then the L-shaped arm 201 performs reciprocating linear motion.

[0028] like Figure 2 As shown, a drive source 202 is provided on the collection box 1, and the drive source 202 is connected to the sliding groove connecting rod 203 for transmission.

[0029] The detailed working process of this embodiment is as follows: the drive source 202 is used to drive the slide rail connecting rod 203 to rotate.

[0030] The aforementioned drive source 202 is a motor. In other embodiments, a suitable drive device can be selected according to the actual situation.

[0031] like Figure 4 As shown, the clamping assembly includes two sets of clamping arms 4 located inside the collection box 1, and a bidirectional stud 401 threadedly connected to the two clamping arms 4. The bidirectional stud 401 is located inside the collection box 1 and its two ends are rotatably connected to the collection box 1.

[0032] The detailed working process of this embodiment is as follows: the bidirectional stud 401 is used to control the two clamping arms 4 to move closer or further apart from each other, and the clamping arms 4 are used to clamp the oil pipe.

[0033] like Figure 4 As shown, rubber pads 402 are provided on the opposite surfaces of the two clamping arms 4.

[0034] The detailed working process of this embodiment is as follows: The function of the rubber pad 402 is to increase the friction and at the same time avoid direct hard contact between the oil pipe and the two clamping arms 4, which would damage the oil pipe.

[0035] like Figure 3 As shown, each burr brush 3 has an inclined surface 301 at one end near the adjusting nut 5.

[0036] The detailed working process of this embodiment is as follows: by setting an inclined surface 301 at one end of multiple sets of burr brushes 3, the diameter formed by each burr brush 3 cooperates with each other, and the ends of multiple inclined surfaces 301 cooperate with each other to form a conical surface, which facilitates entry into the oil pipe.

[0037] The implementation principle of this application embodiment is as follows: First, the oil pipe is placed vertically between the two clamping arms 4. The bidirectional stud 401 is rotated to clamp the oil pipe between the two clamping arms 4. At the same time, the burr brushes 3 are adjusted according to the diameter of the oil pipe so that the diameter formed by the cooperation of the burr brushes 3 corresponds to the diameter of the oil pipe. Then, the drive source 202 is energized to drive the sliding groove connecting rod 203 to rotate. The rotation of the sliding groove connecting rod 203 drives the spiral shaft 2 to move up and down reciprocally. During the up and down reciprocating motion of the spiral shaft 2, it is threadedly connected to the drive seat 102, so that the spiral shaft 2 moves up and down reciprocally while rotating. This causes the burr brushes 3 to move up and down reciprocally while rotating inside the oil pipe, cleaning its inner wall.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
