Description

Technical Field

[0001] The present invention relates to the field of honing machining, and specifically to an honing device for an automotive cylinder block. Background Art

[0002] Both repaired or new cylinder blocks need to be honed for lubrication first. Honing is a finishing process for the machined surface using oilstones (also called honing bars) embedded in the honing head. The contact area between honing and the hole surface is relatively large, and the processing efficiency is relatively high. Under certain conditions, planes can also be processed. After honing, the dimensional accuracy of the hole is IT7 - IT4 level.

[0003] After honing, the dimensional accuracy of the hole is IT7 - IT4 level, and the surface roughness can reach Ra0.32 - 0.04 μm. The size of the honing allowance depends on the hole diameter and the workpiece material. Generally, for cast iron parts, it is 0.02 - 0.15 mm, and for steel parts, it is 0.01 - 0.05 mm. The rotational speed of the honing head is generally 100 - 200 revolutions per minute, and the reciprocating speed is generally 15 - 20 meters per minute. To wash away chips and abrasive grains, improve the surface roughness, and reduce the temperature in the cutting area, a large amount of cutting fluid is often required during operation, such as kerosene or kerosene with a small amount of spindle oil added, and sometimes extreme pressure emulsions are also used.

[0004] During the honing process, a honing machine is mostly used for honing. In this way, workers need to move the heavy automotive cylinder block to the operation area of the honing machine. Due to the differences in automotive cylinder blocks, different oilstones are required. After single - time honing, workers need to replace the oilstone to perform the next honing, which greatly reduces the efficiency. And during the honing process, an external nozzle is required to continuously supply cutting fluid into the cylinder hole to lubricate the contact position between the oilstone and the inner wall of the cylinder block. This will lead to an increase in the usage amount of cutting fluid and relatively poor lubrication effect. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, an honing device for an automotive cylinder block is provided. Different - sized oilstone bars can be installed through the inner oilstone seat and the outer oilstone seat. The cutting fluid is transported into the infusion channel through the liquid - separating mechanism and the liquid - supply mechanism, so that the cutting fluid can accurately spray the contact position between the oilstone bar and the inner wall of the cylinder hole, improving the lubrication effect while reducing the usage amount of cutting fluid.

[0044] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] See Figures 1 to 13 As shown, an automobile cylinder block honing device includes an automobile cylinder block 1; it also includes a C-shaped plate 2, a hydraulic rod 3, a limiting mechanism 4, a housing 5, an outer oilstone seat 6, an inner oilstone seat 61, a liquid supply mechanism 7 and a liquid distribution mechanism 8; a strip-shaped chute 21 is provided at the top of the C-shaped plate 2, and a moving block 22 is slidably arranged in the strip-shaped chute 21; an installation hole 221 is provided at the center of the moving block 22, the hydraulic rod 3 is arranged vertically in the installation hole 221, and an installation frame 31 is provided at the execution part of the hydraulic rod 3, and a driving motor 32 is arranged inside the installation frame 31; the limiting mechanism 4 is arranged on one side of the C-shaped plate 2 and is used to fix the C-shaped plate 2 on the automobile cylinder block 1; the housing 5 is arranged vertically on the output shaft of the driving motor 32, a first hollow rod 51 is slidably arranged inside the housing 5, a second hollow rod 52 is slidably arranged inside the first hollow rod 51, a cylindrical installation sleeve 511 is provided at the bottom of the first hollow rod 51, a trapezoidal depression 5111 is provided on the outer wall of the installation sleeve 511, and a contact block 521 having the same shape as the installation sleeve 511 is provided at the bottom of the second hollow rod 52; the contact block 521 is located inside the installation sleeve 511; a plurality of slots 53 are arranged on the outer circumference of the housing 5, the number of the outer oilstone seats 6 and the inner oilstone seats 61 is the same, the outer oilstone seats 6 and the inner oilstone seats 61 are alternately inserted into the slots 53 of the housing 5 in sequence, and a plurality of avoidance grooves 5113 for avoiding the inner oilstone seats 61 are arranged on the outer wall of the installation sleeve 511 along the circumferential direction; the outer oilstone seats 6 and the inner oilstone seats 61 are respectively slidably matched with the corresponding installation sleeve 511 and contact block 521; oilstone strips 62 for honing are arranged on both the outer oilstone seats 6 and the inner oilstone seats 61; L-shaped liquid infusion channels 63 are arranged inside both the outer oilstone seats 6 and the inner oilstone seats 61, and a plurality of groups of liquid spraying channels 64 for spraying cutting fluid to the oilstone strips 62 are arranged along the length direction inside each liquid infusion channel 63; a liquid containing cavity 5211 communicating with the second hollow rod 52 is arranged inside the contact block 521, the liquid supply mechanism 7 is arranged on the side of the C-shaped plate 2 away from the limiting mechanism 4 and can convey cutting fluid into the liquid containing cavity 5211; the liquid distribution mechanism 8 is arranged on the inner wall of the top of the installation sleeve 511 and can respectively convey the cutting fluid in the liquid containing cavity 5211 to the liquid infusion channels 63 of the corresponding outer oilstone seats 6 and inner oilstone seats 61 as the first hollow rod 51 and the second hollow rod 52 move.

[0046] During use, the staff place the U-shaped plate 2 above the engine block 1 of the vehicle. Subsequently, by adjusting the limiting mechanism 4, the U-shaped plate 2 is fixed on the engine block 1 of the vehicle. At this time, the staff adjust the moving block 22 so that the housing 5 can move into the cylinder hole of the engine block 1 of the vehicle. Subsequently, the first hollow rod 51 is adjusted. As the first hollow rod 51 moves, the mounting sleeve 511 provided at the bottom of the first hollow rod 51 can move along the axial direction of the first hollow rod 51. The outer oilstone seat 6 cooperates with the trapezoidal depression 5111, so that a plurality of outer oilstone seats 6 can move synchronously away from the first hollow rod 51, enabling the oilstone strip 62 to contact the inner wall of the cylinder hole, so that the housing 5 can be located at the center of the corresponding cylinder hole, ensuring the accuracy of honing. Subsequently, the hydraulic rod 3 and the drive motor 32 drive the housing 5 to rotate up and down in a reciprocating manner to hone the engine block. During this process, the liquid supply mechanism 7 can deliver cutting fluid into the liquid containing cavity 5211 through the second hollow rod 52. The liquid distribution mechanism 8 can deliver the cutting fluid located in the liquid containing cavity 5211 into the liquid infusion channel 63 of the outer grinding stone seat as the first hollow rod 51 moves. The cutting fluid can be sprayed onto the contact position between the oilstone strip 62 and the inner wall of the engine block through a plurality of liquid spraying channels 64, improving the honing effect while reducing the usage amount of the cutting fluid. And by providing the second hollow rod 52 and the inner oilstone seat 61, oilstone strips 62 of different specifications can be installed. The staff adjust the second hollow rod 52, and the abutting block 521 provided at the bottom of the second hollow rod 52 can contact the inner oilstone seat 61, so that a plurality of inner oilstone seats 61 can move synchronously away from the center of the housing 5 to meet different usage requirements. After honing a single cylinder hole, only by pushing the moving block 22 can the honing of the next cylinder hole be continued, thus improving the practicality of the device.

[0047] See Figure 4 、 Figure 5 and Figure 10As shown, the liquid separation mechanism 8 includes a sealing collar 81, a first infusion hose 82, and a second infusion hose 83. Along the circumferential direction of the bottom inner wall of the liquid accommodation cavity 5211, a plurality of liquid outlet holes 5212 are equidistantly arranged. The sealing collar 81 is horizontally sleeved on the abutting block 521, and the top of the sealing collar 81 is fixedly connected to the mounting sleeve 511 through a fixing rod 811. Along the circumferential direction of the bottom outer wall of the sealing collar 81, a plurality of first connection holes 812 corresponding to the inner oilstone seat 61 are arranged. The first connection holes 812 are communicated with the infusion channel 63 of the inner oilstone seat 61 through the first infusion hose 82. Along the circumferential direction of the top outer wall of the sealing collar 81, a plurality of second connection holes 813 corresponding to the outer oilstone seat 6 are arranged. The second connection holes 813 are communicated with the infusion channel 63 of the outer oilstone seat 6 through the second infusion hose 83. The first connection holes 812 and the second connection holes 813 are arranged in sequence along the circumferential direction of the sealing collar 81. A plurality of avoidance holes 5114 for avoiding the second infusion hose 83 are arranged on the mounting sleeve 511.

[0048] In the axial direction, the liquid outlet holes 5212 are located between the first connection holes 812 and the second connection holes 813. The sealing collar 81 can block the liquid outlet holes 5212, thereby preventing the cutting fluid from leaking from the liquid outlet holes 5212. When honing is required, the staff adjusts the second hollow rod 52, and the second hollow rod 52 pushes a plurality of inner oilstone seats 61 to move synchronously away from the center of the housing 5, so that the oilstone strips 62 provided on the inner oilstone seats 61 can contact the inner wall of the cylinder hole. At this time, the first hollow rod 51 is in a static state. At this time, as the second hollow rod 52 moves, the abutting block 521 provided on the second hollow rod 52 can move vertically downward. During this process, the liquid outlet holes 5212 can be communicated with the first connection holes 812 on the bottom outer wall of the sealing collar 81. At this time, the cutting fluid can enter the infusion channel 63 inside the inner oilstone seat 61 through the first infusion hose 82. With the cooperation of the driving motor 32 and the hydraulic rod 3, during the honing process, the cutting fluid can be sprayed out through the liquid spraying channel 64 to continuously spray the contact position between the oilstone strip 62 and the inner wall of the cylinder hole, thereby improving the honing effect. When oilstone strips 62 of other specifications are needed, the staff can adjust the first hollow rod 51. At this time, the second hollow rod 52 is in a static state. The second connection holes 813 on the sealing collar 81 can be connected to the liquid outlet holes 5212, and the cutting fluid can be transported to the infusion channel 63 of the outer oilstone seat 6 through the second infusion hose 83, so as to ensure that during the honing process of the oilstone strips 62 on the outer oilstone seat 6, the cutting fluid can be continuously sprayed.

[0049] See Figure 1 、 Figure 2 and Figure 11As shown, the liquid supply mechanism 7 includes a liquid storage tank 71, a delivery hose 72, and an air pump 73; a connecting sleeve 321 is provided on the output shaft of the drive motor 32, the housing 5 is fixedly arranged inside the connecting sleeve 321, and a liquid-electric slip ring 322 is fixedly sleeved outside the connecting sleeve 321. A liquid inlet hole 522 is provided on the outer wall of the top of the second hollow rod 52. The output end of the liquid-electric slip ring 322 is communicated with the liquid inlet hole 522 through a connecting hose 3221; the liquid storage tank 71 is arranged vertically on the side of the C-shaped plate 2 away from the limiting mechanism 4. A feeding port 711 is provided at the top of the liquid storage tank 71, and a discharge port 712 is provided at the center of the bottom of the liquid storage tank 71. One end of the delivery hose 72 is arranged at the discharge port 712, and the other end of the delivery hose 72 is connected to the input end of the liquid-electric slip ring 322; the air pump 73 is arranged on the top of the liquid storage tank 71, and the output end of the air pump 73 extends into the liquid storage tank 71.

[0050] The liquid-electric slip ring 322 is a through-hole type liquid-electric slip ring 322. The outer ring of the liquid-electric slip ring 322 is fixedly connected to the mounting frame 31, and the inner ring of the liquid-electric slip ring 322 is fixedly sleeved on the connecting sleeve 321. The staff conveys the cutting fluid into the liquid storage tank 71 through the feeding port 711. The setting of the air pump 73 can ensure that the cutting fluid can be conveyed to the input end of the liquid-electric slip ring 322 through the delivery hose 72. The liquid-electric slip ring 322 conveys the cutting fluid into the second hollow rod 52 that rotates with the housing 5 through the connecting hose 3221, thereby ensuring the supply of the cutting fluid.

[0051] See Figure 4 、 Figure 6 、 Figure 7 and Figure 9 As shown in, at the top of the side of the inner oilstone seat 61 and the outer oilstone seat 6 close to the housing 5, there are trapezoidal guiding blocks 65 that cooperate with the trapezoidal recess 5111. A plurality of first guiding rods 51111 for guiding the outer oilstone seat 6 are arranged along the circumferential direction on the lower surface of the trapezoidal recess 5111. The first guiding rods 51111 are located between two adjacent avoidance grooves 5113. A plurality of second guiding rods 5213 for guiding the inner oilstone seat 61 are arranged along the circumferential direction on the outer wall of the abutting block 521. The second guiding rods 5213 correspond to the avoidance grooves 5113 one by one. The first guiding rods 51111 and the second guiding rods 5213 have the same shape. Each trapezoidal guiding block 65 is provided with guiding holes 651 that cooperate with the first guiding rods 51111 and the second guiding rods 5213.

[0052] The first guide rod 51111 and the second guide rod 5213 are both arranged at an acute angle with respect to the axis of the housing 5. When in use, the operator adjusts the first hollow rod 51, and the first hollow rod 51 moves vertically downward. During this process, the upper surface of the trapezoidal depression 5111 can contact the upper surface of the trapezoidal guide block 65, so that the multiple trapezoidal guide blocks 65 arranged on the outer oilstone seat 6 can move synchronously away from the axis of the housing 5, thereby bringing the oilstone strip 62 into contact with the inner wall of the cylinder hole. When oilstone strips 62 of different specifications are needed, the operator adjusts the first hollow rod 51. The inclined first guide rod 51111 can cooperate with the guide hole 651 on the trapezoidal guide block 65, so that the outer oilstone seat 6 can be retracted into the slot 53. At this time, when adjusting the second hollow rod 52, with the cooperation of the abutting block 521 and the trapezoidal guide block 65, the oilstone strip 62 located on the inner oilstone seat 61 can be brought into contact with the inner wall of the cylinder body, thus completing the replacement of oilstone strips 62 of different specifications.

[0053] See Figure 4 、 Figure 7 and Figure 8 As shown, a first limiting ring 512 is fixedly arranged on the first hollow rod 51. The first limiting ring 512 is located inside the housing 5.

Two bolt holes 524 are mirror-symmetrically arranged on the outer wall of the second hollow rod 52. The second limiting ring 523 is fixedly connected to the second hollow rod 52 through bolts 525. Two strip-shaped connection grooves 514 for avoiding the bolts 525 are arranged on the outer wall of the first hollow rod 51. The second limiting ring 523 is located between the first limiting ring 512 and the positioning ring 54. A second return spring 515 is also sleeved on the first hollow rod 51. The second return spring 515 is located between the second limiting ring 523 and the positioning ring 54 and is inside the first return spring 513.

[0054] By providing the first return spring 513 and the second return spring 515, in the non-use state, the first return spring 513 and the second return spring 515 can reset the first hollow rod 51 and the second rod. A spacer sleeve is also arranged between the first return spring 513 and the second return spring 515, so as to avoid volume collision between the first return spring 513 and the second return spring 515 during use, so that the inner oilstone seat 61 and the outer oilstone seat 6 can be retracted into the slot 53 and prevent damage to the oilstone strip 62. By arranging a linear actuator in the connecting sleeve 321 of the drive motor 32, the linear actuator pushes the corresponding first hollow rod 51 and second hollow rod 52 to move, so as to adjust the positions of the inner oilstone seat 61 and the outer oilstone seat 6, thereby meeting different use requirements.

[0055] See Figure 4 、 Figure 5 and Figure 10 As shown, a sealing mechanism 9 is further provided on the second hollow rod 52, which can rotate with the housing 5 to open and block the inside of the second hollow rod 52; the sealing mechanism 9 includes a sealing plate 91 and a vertical plate 92; an arc-shaped notch 526 for inserting the sealing plate 91 is provided on the outer wall of the second hollow rod 52, and the arc-shaped notch 526 communicates with the inside of the second hollow rod 52; the sealing plate 91 is horizontally arranged and slidably arranged in the arc-shaped notch 526, and the vertical plate 92 is vertically arranged on the top of the abutting block 521; two sliding holes 921 are symmetrically arranged on the vertical plate 92, and two sliding rods 911 cooperating with the sliding holes 921 are arranged on the side of the sealing plate 91 close to the vertical plate 92, and the sliding rods 911 pass through the arc-shaped notch 526 and are slidably arranged in the corresponding sliding holes 921; a compression spring 912 is sleeved on each sliding rod 911, and the compression spring 912 is located between the vertical plate 92 and the sealing plate 91; a traction rope 913 is further arranged at the center of the side of the sealing plate 91 close to the vertical plate 92, and the traction rope 913 passes through the vertical plate 92 and is provided with a counterweight ball 914.

[0056] When the housing 5 is in the non-rotating state, the compression spring 912 sleeved on the sliding rod 911 can push the sealing plate 91 into the inside of the second hollow rod 52, so as to cut off the inside of the second hollow rod 52, avoiding the leakage of the cutting fluid from the liquid spraying channel 64 when honing is not carried out, resulting in the waste of the cutting fluid. When the housing 5 rotates, the second hollow rod 52 rotates with the rotation of the housing 5. At this time, the counterweight ball 914 rotates along the axis of the second hollow rod 52 with the rotation of the housing 5. With the rotation of the counterweight ball 914, a centrifugal force is generated. The counterweight ball 914 pulls the sealing plate 91 through the traction rope 913 so that it can overcome the elastic force of the compression spring 912 and move in a direction away from the second hollow rod 52, so that the inside of the second hollow rod 52 is in a communicating state, and the cutting fluid can enter the liquid containing cavity 5211 through the inside of the second hollow rod 52, so as to spray the contact position between the oil stone strip 62 and the inner wall of the cylinder block.

[0057] See Figure 1 and Figure 11 As shown, the limiting mechanism 4 includes a resisting plate 41 and a threaded rod 42; the resisting plate 41 is vertically arranged, a sliding block 411 is arranged on the top of the resisting plate 41, and the sliding block 411 is slidably arranged in the strip-shaped sliding groove 21; a threaded hole 23 is arranged on the side of the U-shaped plate 2 away from the liquid storage tank 71, the threaded rod 42 is threadedly connected with the threaded hole 23, a bearing hole 412 is arranged on the side of the resisting plate 41 close to the threaded rod 42, and a bearing 413 is arranged in the bearing hole 412; one end of the threaded rod 42 extending into the U-shaped plate 2 is fixedly arranged inside the bearing 413.

[0058] One end of the threaded rod 42 away from the contact plate 41 is provided with a rotating handle 421. The staff places the U-shaped plate 2 above the engine block 1 of the vehicle and ensures that the length direction of the strip-shaped chute 21 is the same as the arrangement direction of the cylinder holes of the engine block 1 of the vehicle. Subsequently, the staff adjusts the rotating handle 421. The threaded rod 42 is threadedly connected to the threaded hole 23 on the U-shaped plate 2, thereby pushing the contact plate 41 to move towards the engine block 1. When the contact plate 41 contacts the engine block 1, the entire U-shaped plate 2 is fixed above the engine block 1. Subsequently, the cylinder holes can be honed in sequence, reducing the steps of moving the engine block 1 of the vehicle and improving the honing efficiency. Moreover, rubber pads 25 are provided on the inner wall of the side of the U-shaped plate 2 away from the threaded rod 42 and on the side of the contact plate 41 away from the threaded rod 42. By providing the rubber pads 25, the engine block 1 of the vehicle can be protected to avoid damage to the surface of the engine block 1 of the vehicle.

[0059] See Figure 1 and Figure 11 As shown, two parallel connecting bars 24 are further provided inside the U-shaped plate 2. The length directions of the two connecting bars 24 are the same as the length direction of the strip-shaped chute 21 and are respectively located on both sides of the strip-shaped chute 21. Two rectangular notches for avoiding the connecting bars 24 are provided on the contact plate 41.

[0060] By providing the connecting bars 24, the two connecting bars 24 are located on both sides of the strip-shaped chute 21. The two connecting bars 24 can not only reinforce the U-shaped plate 2 but also enable the U-shaped plate 2 to be placed above the engine block 1 of the vehicle. The two connecting bars 24 are located on both sides of the arrangement direction of the cylinder holes, thereby being able to improve the installation speed of the U-shaped plate 2.

[0061] See Figure 4 、 Figure 12 and Figure 13 As shown, each group of liquid spraying channels 64 includes two V-shaped communication holes 641 symmetrically arranged with respect to the corresponding liquid infusion channels 63. Each V-shaped communication hole 641 is communicated with the liquid infusion channel 63, and the inner diameter of each V-shaped communication hole 641 gradually decreases along the flowing direction of the cutting fluid.

[0062] The inner diameter of the V-shaped communication hole 641 gradually decreases along the flowing direction of the cutting fluid inside it. When the cutting fluid flows into the V-shaped communication hole 641, the gradually decreasing aperture can accelerate the cutting fluid, enabling it to impact the contact position between the oilstone strip 62 and the inner wall of the cylinder hole faster. And through multiple groups of symmetrically arranged V-shaped communication holes 641, the cutting fluid can collide at the contact position between the oilstone strip 62 and the inner wall of the cylinder hole, thereby removing the honed particles and improving the honing effect.

[0063] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
