Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of brake caliper, in particular to a brake caliper debris cleaning device. BACKGROUND

[0002] The brake caliper is a core component of the hydraulic disc brake. Figure 1 The partial structure of the brake caliper is shown; referring to Figure 1 As shown, the rectangular groove 111 and the dustproof groove 112 are arranged in the cylinder hole 11 of the brake caliper 10. When the rectangular groove 111 and the dustproof groove 112 are machined, iron filings 113 are easily stuck in the grooves, which need to be cleaned.

[0003] The current debris cleaning equipment either adopts simple blowing or simple scraping, which cannot stably and efficiently remove the iron filings 113. The residual iron filings 113 in the rectangular groove 111 / dustproof groove 112 can cause brake fluid leakage in the brake caliper 10, resulting in safety accidents.

[0004] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present application, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0005] Therefore, the present application provides a brake caliper debris cleaning device. The rotating debris removal mechanism is driven by the rotating shaft to rotate stably and efficiently scrape the residual iron filings in the debris cleaning groove of the brake caliper. The rotating debris removal mechanism can be folded and unfolded with the forward and reverse rotation of the rotating shaft, which is simple and effective to realize folding to extend into the cylinder hole of the brake caliper and unfolding to extend into the debris cleaning groove.

[0006] According to one aspect of the present application, a brake caliper debris cleaning device is provided, comprising: a support rod, a positioning core connected to the top of the support rod; a rotating shaft, which is gap-sheathed outside the support rod, and the end face of the rotating shaft is provided with a boss; a rotating debris removal mechanism, which is gap-sheathed outside the support rod and limited between the end face of the rotating shaft and the positioning core, and the rotating debris removal mechanism comprises a debris removal head rotatably penetrating a positioning pin; when the rotating shaft rotates in a first direction, the boss can push the first end of the debris removal head to make the second end of the debris removal head fold towards the axis of the support rod; when the rotating shaft rotates in a second direction, the boss can push the second end of the debris removal head to make the second end of the debris removal head unfold away from the axis of the support rod.

[0007] The debris removing device of the present application can extend into the cylinder hole of the brake caliper through the support rod connected with the positioning core at the top, the cylinder hole is positioned and fixed by the positioning core, and the support rod supports the brake caliper, the rotating shaft and the rotating debris removing mechanism as a whole; the rotating debris removing mechanism is sleeved outside the support rod and is limited between the end surface of the rotating shaft and the positioning core, can realize rotation and avoid axial movement; the boss of the rotating shaft cooperates with the debris removing head of the rotating debris removing mechanism, can push the first end of the debris removing head to make the second end of the debris removing head fold, at this time, the rotating debris removing mechanism can extend into the cylinder hole of the brake caliper, and can push the second end of the debris removing head to make the second end of the debris removing head open, at this time, the second end of the debris removing head can extend into the debris removing groove of the brake caliper; in the open state, the rotating shaft continues to rotate in the second direction, can drive the rotating debris removing mechanism to rotate stably so that the debris removing head efficiently scrapes the residual iron filings in the debris removing groove;

[0008] The debris removing device of the present application can extend into the cylinder hole of the brake caliper through the support rod connected with the positioning core at the top, the cylinder hole is positioned and fixed by the positioning core, and the support rod supports the brake caliper, the rotating shaft and the rotating debris removing mechanism as a whole; the rotating debris removing mechanism is sleeved outside the support rod and is limited between the end surface of the rotating shaft and the positioning core, can realize rotation and avoid axial movement; the boss of the rotating shaft cooperates with the debris removing head of the rotating debris removing mechanism, can push the first end of the debris removing head to make the second end of the debris removing head fold, at this time, the rotating debris removing mechanism can extend into the cylinder hole of the brake caliper, and can push the second end of the debris removing head to make the second end of the debris removing head open, at this time, the second end of the debris removing head can extend into the debris removing groove of the brake caliper; in the open state, the rotating shaft continues to rotate in the second direction, can drive the rotating debris removing mechanism to rotate stably so that the debris removing head efficiently scrapes the residual iron filings in the debris removing groove;

[0009] In some embodiments, the inner wall surface of the debris removing head forms an arc surface matched with the outer wall surface of the support rod; when the rotating shaft rotates in the first direction, the second end of the debris removing head folds to the arc surface and abuts against the outer wall surface of the support rod.

[0010] By matching the inner wall surface of the debris removing head with the outer wall surface of the support rod, the second end of the debris removing head folds to the arc surface and abuts against the outer wall surface of the support rod, so that a stable folding state is achieved to smoothly extend into the cylinder hole of the brake caliper.

[0011] In some embodiments, the end of the second end of the debris removing head forms a synapse matched with the debris removing groove of the brake caliper; when the rotating shaft rotates in the second direction, the second end of the debris removing head opens to the synapse and abuts against the debris removing groove.

[0012] By matching the end of the second end of the debris removing head with the debris removing groove of the brake caliper, the second end of the debris removing head opens to the synapse and abuts against the debris removing groove, so that a stable open state is achieved to further rotate and scrape the residual iron filings in the debris removing groove in the open state.

[0013] In some embodiments, the two ends of the boss in the circumferential direction are flat; when the debris removing head is in the folding state, one end of the boss can be inserted into the gap between the second end of the debris removing head and the support rod; when the debris removing head is in the open state, the other end of the boss can be inserted into the gap between the first end of the debris removing head and the support rod.

[0014] The flat ends of the convex platform can be smoothly inserted into the gap between the second end of the debris-removing head and the supporting rod in the collapsed state of the debris-removing head, thereby gradually applying force to the second end of the debris-removing head to push the debris-removing head to expand, and can be smoothly inserted into the gap between the first end of the debris-removing head and the supporting rod in the expanded state of the debris-removing head, thereby gradually applying force to the first end of the debris-removing head to push the debris-removing head to collapse.

[0015] In some embodiments, the convex platform has two circumferentially distributed inclined surfaces; when the rotating shaft rotates around the first direction, one inclined surface of the convex platform abuts against the inner wall surface of the first end of the debris-removing head; when the rotating shaft rotates around the second direction, the other inclined surface of the convex platform abuts against the inner wall surface of the second end of the debris-removing head.

[0016] The convex platform can form surface contact with the inner wall surface of the corresponding end of the debris-removing head through the two circumferentially distributed inclined surfaces when pushing the debris-removing head to collapse and expand, respectively, so as to stabilize and reliably rotate the debris-removing head.

[0017] In some embodiments, the debris-removing head includes a plurality of circumferentially uniformly and spacedly distributed.

[0018] In this way, the debris-removing head can form multi-point contact with the to-be-cleaned groove in the expanded state, so as to efficiently rotate and scrape the residual iron filings in the to-be-cleaned groove.

[0019] In some embodiments, the rotating debris-removing mechanism further includes a rotating sleeve, which is gapingly sleeved on the outside of the supporting rod and is limited between the end surface of the rotating shaft and the positioning core, and the rotating sleeve includes two parts that are detachably connected by the positioning pin.

[0020] The rotating sleeve includes two parts that are detachably connected by the positioning pin, facilitating installation and replacement of the debris-removing head.

[0021] In some embodiments, the bottom of the supporting rod is connected with a gas blowing head and is internally provided with a gas passage; the rotating debris-removing mechanism is provided with a gas outlet passage that is in communication with the gas passage.

[0022] In this way, the to-be-cleaned groove can be swept when the rotating debris-removing mechanism rotates and scrapes the residual iron filings in the to-be-cleaned groove, ensuring that the iron filings completely separate from the to-be-cleaned groove.

[0023] In some embodiments, the gas outlet passage has at least one gas outlet that is circumferentially distributed on the outer peripheral wall of the rotating debris-removing mechanism; or the gas outlet passage has a ring-shaped gas outlet that is located on the outer peripheral wall of the rotating debris-removing mechanism.

[0024] The position of the gas outlet is towards the to-be-cleaned groove, achieving sweeping of the iron filings in the to-be-cleaned groove.

[0025] In some embodiments, the outer wall of the support rod is provided with at least two mounting grooves, respectively located on the axial sides of the outlet of the gas passage; a sealing ring is mounted in each of the mounting grooves, and the sealing ring is pressed between the mounting groove and the inner circumferential wall of the rotary chip removal mechanism.

[0026] The sealing ring forms a seal on the axial sides of the outlet of the gas passage, ensuring that the gas output from the outlet of the gas passage enters the gas outlet passage of the rotary chip removal mechanism, and avoiding gas leakage.

[0027] In some embodiments, when the rotary shaft rotates in the second direction, the rotary chip removal mechanism has two stages executed in sequence; in the first stage, the boss pushes the chip removal head to rotate around the positioning pin to open the second end of the chip removal head; in the second stage, the boss pushes the rotary chip removal mechanism to rotate around the support rod.

[0028] Due to the damping effect of the sealing ring, in the first stage, the rotary sleeve does not rotate with the rotary shaft, and the chip removal head can rotate around the positioning pin to open the contact with the to-be-cleaned chip groove; in the second stage, the second end of the chip removal head abuts against the to-be-cleaned chip groove, and at this time, as the rotary shaft rotates, the rotary sleeve overcomes the damping effect of the sealing ring, and the rotary chip removal mechanism as a whole rotates around the support rod to rotate the chip removal.

[0029] In some embodiments, the chip removal device further comprises a rotary driving mechanism supported on the device bottom plate; a synchronous transmission mechanism connected to the rotary driving mechanism and the rotary shaft, the synchronous transmission mechanism comprising two synchronous wheels respectively connected to the output shaft of the rotary driving mechanism and the rotary shaft, and a synchronous belt connecting the two synchronous wheels.

[0030] The power of the rotary driving mechanism is transmitted to the rotary shaft through the two synchronous wheels respectively connected to the output shaft of the rotary driving mechanism and the rotary shaft, and the synchronous belt connecting the two synchronous wheels, to drive the rotary shaft to rotate.

[0031] In some embodiments, the rotary shaft is supported on the device bottom plate through a bearing assembly, the bearing assembly comprising: a bearing seat fixed to the device bottom plate; a ball bearing installed in the bearing seat, the outer ring of the ball bearing being in interference fit with the bearing seat and the inner ring being in interference fit with the rotary shaft; and a bearing cover fixed to the bearing seat and covering the ball bearing and the part of the rotary shaft in contact with the inner ring.

[0032] The rotary shaft is supported by the bearing assembly, ensuring that the rotary shaft can stably rotate; the outer ring of the ball bearing is in interference fit with the bearing seat and the inner ring is in interference fit with the rotary shaft, so that the ball bearing supports the rotary shaft to rotate; the bearing cover limits the ball bearing and the rotary shaft, avoiding the rotary shaft and the ball bearing from being separated from the bearing seat.

[0033] In some embodiments, the debris removing device further comprises a pair of positioning bases fixed to the device bottom plate and located at both sides of the support rod.

[0034] The two ears of the support brake caliper are positioned by the pair of positioning bases located at both sides of the support rod, so that the brake caliper is kept stable for debris removal.

[0035] The present application has at least the following advantages compared with the prior art:

[0036] The debris removing device of the present application can extend into the cylinder hole of the brake caliper through the support rod connected with the positioning core at the top, the cylinder hole is positioned and fixed by the positioning core, and the support rod supports the brake caliper, the rotating shaft and the rotating debris removing mechanism as a whole; the rotating debris removing mechanism is sleeved outside the support rod and is limited between the end face of the rotating shaft and the positioning core, so that it can rotate and avoid axial movement; the boss of the rotating shaft cooperates with the debris removing head of the rotating debris removing mechanism, so that the first end of the debris removing head is pushed to make the second end of the debris removing head fold, at this time the rotating debris removing mechanism can extend into the cylinder hole of the brake caliper, and the second end of the debris removing head can be pushed to make the second end of the debris removing head open, at this time the second end of the debris removing head can extend into the debris removing groove of the brake caliper; in the open state, the rotating shaft continues to rotate in the second direction, which can drive the rotating debris removing mechanism to rotate stably so that the debris removing head can efficiently remove the residual debris in the debris removing groove;

[0037] The debris removing device of the present application drives the rotating debris removing mechanism to fold and open by the forward and reverse rotation of the rotating shaft, so that the debris removing head extends into the cylinder hole and the debris removing groove of the brake caliper, and further rotates to remove the residual debris in the debris removing groove, which has simple overall structure, convenient operation and maintenance, and meets the production requirements of high efficiency and low cost.

[0055] Figure 2 The structure of the debris removing device in the embodiment of the present application is shown, Figure 3 The cross-sectional structure of the debris removing device is shown, Figure 4 The structure of the brake caliper positioned in the debris removing device is shown, Figure 5 The structure of the rotating shaft is shown, Figure 6 The structure of the rotating shaft and the rotating debris removing mechanism being sleeved on the support rod is shown, Figure 7 The structure of the debris removing head is shown, Figure 8 The cooperation structure of the rotating debris removing mechanism, the rotating shaft and the support rod in the folded state is shown, Figure 9 The cooperation structure of the rotating debris removing mechanism, the rotating shaft and the support rod in the unfolded state is shown; in combination Figures 1 to 9 As shown in the combination, the debris removing device of the brake caliper provided by the embodiment of the present application comprises:

[0056] The support rod 20, the top of the support rod 20 is connected with the positioning core 22;

[0057] The rotating shaft 30, the gap is sleeved outside the support rod 20, and the end face of the rotating shaft 30 is provided with the boss 33;

[0058] The rotating debris removing mechanism 40, the gap is sleeved outside the support rod 20 and is limited between the end face of the rotating shaft 30 and the positioning core 22, and the rotating debris removing mechanism 40 comprises the debris removing head 44 rotatably penetrating the positioning pin 42;

[0059] When the rotating shaft 30 rotates around the first direction R1, the boss 33 can push the first end 44a of the debris removing head 44, so that the second end 44b of the debris removing head 44 is folded towards the axis of the support rod 20;

[0060] When the rotating shaft 30 rotates around the second direction R2, the boss 33 can push the second end 44b of the debris removing head 44, so that the second end 44b of the debris removing head 44 is unfolded away from the axis of the support rod 20.

[0061] Among them, the first end 44a and the second end 44b of the debris removing head 44 are relative to the positioning pin 42, and the first end 44a and the second end 44b of the debris removing head 44 are located on the two circumferential sides of the positioning pin 42 respectively.

[0062] The support rod 20 with the positioning core 22 connected at the top can extend into the cylinder hole of the brake caliper 10, the positioning core 22 is used for positioning and fixing the cylinder hole, and the support rod 20 supports the brake caliper 10 and the rotating shaft 30 and the rotating scrap removing mechanism 40 as a whole. The rotating scrap removing mechanism 40 is sleeved outside the support rod 20 and is limited between the end face of the rotating shaft 30 and the positioning core 22, can rotate and avoid axial movement. The boss 33 of the rotating shaft 30 cooperates with the scrap removing head 44 of the rotating scrap removing mechanism 40, can push the first end 44a of the scrap removing head 44 to make the second end 44b of the scrap removing head 44 close, at this time, the rotating scrap removing mechanism 40 can extend into the cylinder hole of the brake caliper 10, and the second end 44b of the scrap removing head 44 can be pushed to make the second end 44b of the scrap removing head 44 open, at this time, the second end 44b of the scrap removing head 44 can extend into the to-be-cleaned scrap groove (that is, the rectangular groove and the dustproof groove of the brake caliper 10) of the brake caliper 10; in the open state, the rotating shaft 30 continues to rotate in the second direction R2, and can drive the rotating scrap removing mechanism 40 to stably rotate, so that the scrap removing head 44 efficiently scrapes the residual iron scraps in the to-be-cleaned scrap groove.

[0063] The above-mentioned scrap removing device drives the rotating scrap removing mechanism 40 to close and open through the forward and reverse rotation of the rotating shaft 30, so that the scrap removing head 44 extends into the cylinder hole and the to-be-cleaned scrap groove of the brake caliper 10, and further rotates to scrape the residual iron scraps in the to-be-cleaned scrap groove, and the overall structure is simple, the operation and maintenance are convenient, and the production requirements of high efficiency and low cost are met.

[0064] In some embodiments, in combination with Figures 4 to 8 As shown, the inner wall surface of the scrap removing head 44 forms an arc surface 441 matched with the outer wall surface 201 of the support rod 20; when the rotating shaft 30 rotates in the first direction R1, the second end 44b of the scrap removing head 44 closes to the arc surface 441 and abuts against the outer wall surface 201 of the support rod 20.

[0065] In this way, when the rotating shaft 30 rotates in the first direction R1, the second end 44b of the scrap removing head 44 can be driven to close to the arc surface 441 and abut against the outer wall surface 201 of the support rod 20, so that a stable closing state is achieved. In the closing state, the outer contour size of the scrap removing head 44 is smaller than the size of the cylinder hole 11 of the brake caliper 10, so that the rotating scrap removing mechanism 40 can smoothly extend into the cylinder hole 11 of the brake caliper 10.

[0066] In some embodiments, in combination with Figures 4 to 7 and Figure 9 As shown, the end of the second end 44b of the scrap removing head 44 forms a synapse matched with the to-be-cleaned scrap groove of the brake caliper 10 (wherein the first synapse 442 is matched with the rectangular groove 111 of the brake caliper 10, and the second synapse 443 is matched with the dustproof groove 112 of the brake caliper 10); when the rotating shaft 30 rotates in the second direction R2, the second end 44b of the scrap removing head 44 opens to the synapse and abuts against the to-be-cleaned scrap groove.

[0067] By matching the tip of the second end 44b of the debris removing head 44 with the debris clearing groove of the brake caliper 10, the second end 44b of the debris removing head 44 is expanded to abut the debris clearing groove, achieving a stable expansion state, so as to further rotate and scrape the residual debris in the debris clearing groove in the expanded state.

[0068] In some embodiments, as shown in Figure 5 , Figure 8 and Figure 9 , the two ends of the boss 33 are flat in the circumferential direction; when the debris removing head 44 is in the collapsed state, one end 33a of the boss 33 can be inserted into the gap between the second end 44b of the debris removing head 44 and the support rod 20; when the debris removing head 44 is in the expanded state, the other end 33b of the boss 33 can be inserted into the gap between the first end 44a of the debris removing head 44 and the support rod 20.

[0069] The two ends of the boss 33 are flat in the circumferential direction, which can smoothly insert into the gap between the second end 44b of the debris removing head 44 and the support rod 20 in the collapsed state of the debris removing head 44, thereby gradually applying force to the second end 44b of the debris removing head 44 to push the debris removing head 44 to expand, and smoothly insert into the gap between the first end 44a of the debris removing head 44 and the support rod 20 in the expanded state of the debris removing head 44, thereby gradually applying force to the first end 44a of the debris removing head 44 to push the debris removing head 44 to collapse.

[0070] In some embodiments, as shown in Figure 5 , Figure 8 and Figure 9 , the boss 33 has two inclined surfaces distributed in the circumferential direction; when the rotating shaft 30 rotates in the first direction R1, one inclined surface 331 of the boss 33 abuts the inner wall surface of the first end 44a of the debris removing head 44; when the rotating shaft 30 rotates in the second direction R2, the other inclined surface 332 of the boss 33 abuts the inner wall surface of the second end 44b of the debris removing head 44.

[0071] The boss 33 can form a surface contact with the inner wall surface of the corresponding end of the debris removing head 44 through the two inclined surfaces distributed in the circumferential direction when pushing the debris removing head 44 to collapse and expand, respectively, so that the rotation of the debris removing head 44 is stable and reliable.

[0072] In some embodiments, as shown in Figures 3 to 6 , Figure 8 and Figure 9 , the debris removing head 44 includes a plurality of circumferentially uniformly spaced bosses.

[0073] In this way, the debris removing head 44 can form multiple-point contact with the debris clearing groove in the expanded state, so as to efficiently rotate and scrape the residual debris in the debris clearing groove.

[0074] Figure 10 The structure of the rotating sleeve in the embodiment of the application is shown; in combination Figures 2 to 10 As shown in the figure, in some embodiments, the rotating scrap removing mechanism 40 further comprises a rotating sleeve 41, which is gap-set outside the support rod 20 and is limited between the end face of the rotating shaft 30 and the positioning core 22, and the rotating sleeve 41 comprises two parts which are detachably connected by a positioning pin 42.

[0075] The rotating sleeve 41 comprises two parts which are detachably connected by the positioning pin 42, facilitating the installation and replacement of the scrap removing head 44. Among them, the scrap removing head 44 is provided with a positioning hole 444 which is matched with the positioning pin 42, and the positioning hole 444 is gap-fitted with the positioning pin 42, so as to rotate the scrap removing head 44 around the positioning pin 42.

[0076] Figure 11 The structure of the support rod in the embodiment of the application is shown; in combination Figure 3 , Figure 6 , Figure 10 and Figure 11 As shown in the figure, in some embodiments, the bottom of the support rod 20 is connected with a blowing head 202, and the inside is provided with a gas passage 204; the rotating scrap removing mechanism 40 is provided with an air outlet passage 404 which is communicated with the gas passage 204.

[0077] The blowing head 202 can be fastened at the bottom of the support rod 20 through its own thread. The gas is transmitted through the air inlet of the blowing head 202, the gas passage 204 and the air outlet passage 404, which can blow during the rotation of the rotating scrap removing mechanism 40 to scrape off the residual iron filings in the to-be-cleaned scrap groove, ensuring that the iron filings completely separate from the to-be-cleaned scrap groove.

[0078] In some embodiments, the air outlet passage 404 has at least one air outlet 404' which is circumferentially distributed on the outer peripheral wall of the rotating scrap removing mechanism 40; or, the air outlet passage 404 has an annular air outlet which is located on the outer peripheral wall of the rotating scrap removing mechanism 40.

[0079] The position of the air outlet is towards the to-be-cleaned scrap groove, i.e. towards the rectangular groove and the dustproof groove of the brake caliper, which can realize 360° blowing and realize the blowing of the iron filings in the to-be-cleaned scrap groove.

[0080] In some embodiments, the outer wall surface of the support rod 20 is provided with at least two circles of mounting grooves 206 which are respectively located on the axial two sides of the outlet 204' of the gas passage 204; a sealing ring 208 is mounted in the mounting groove 206, and the sealing ring 208 is press-bonded between the mounting groove 206 and the inner peripheral wall of the rotating scrap removing mechanism 40, i.e. press-bonded between the mounting groove 206 and the inner peripheral wall of the rotating sleeve 41.

[0081] The sealing ring 208 forms a seal on both axial sides of the outlet 204' of the gas passage 204, ensuring that the gas output from the outlet 204' of the gas passage 204 enters the gas outlet passage 404 of the rotating sleeve 41, avoiding gas leakage.

[0082] Further, as shown in Figure 3 , Figure 6 and Figure 9 , in some embodiments, when the rotating shaft 30 rotates in the second direction R2, the rotating chip removal mechanism 40 has two stages executed in sequence; in the first stage, the boss 33 pushes the chip removal head 44 to rotate around the positioning pin 42 to the second end 44b of the chip removal head 44 to be opened; in the second stage, the boss 33 pushes the rotating chip removal mechanism 40 to rotate around the support rod 20.

[0083] Due to the damping effect of the sealing ring 208, in the first stage, the rotating sleeve 41 does not rotate with the rotating shaft 30, and then the chip removal head 44 can rotate around the positioning pin 42 to open the contact to be cleaned. The chip groove, in the second stage, the second end 44b of the chip removal head 44 abuts against the chip groove to be cleaned, at this time, as the rotating shaft 30 rotates, the rotating sleeve 41 overcomes the damping effect of the sealing ring 208, and the rotating chip removal mechanism 40 rotates as a whole around the support rod 20 to rotate the chip removal.

[0084] Further, as shown in Figures 2 to 4 , in some embodiments, the chip removal device further comprises: a rotating drive mechanism 60 supported on the device bottom plate 50; a synchronous transmission mechanism connected between the rotating drive mechanism 60 and the rotating shaft 30, the synchronous transmission mechanism comprising two synchronous wheels 72 connected with the output shaft of the rotating drive mechanism 60 and the rotating shaft 30 respectively, and a synchronous belt 74 connected between the two synchronous wheels 72.

[0085] The rotating drive mechanism 60 is, for example, an electric motor, but is not limited thereto. The synchronous wheels 72 can be fixed on the output shaft of the rotating drive mechanism 60 and the rotating shaft 30 by means of a top screw. Through the synchronous transmission mechanism, the power of the rotating drive mechanism 60 is transmitted to the rotating shaft 30 to drive the rotating shaft 30 to rotate around the support rod 20.
