Description

Technical Field

[0001] The invention relates to the technical field of brake pad processing, in particular to a steel back feeder for processing and manufacturing vehicle brake pads. Background Art

[0002] As an important part of the brake pad, the brake pad steel backing provides a stable support surface for fixing high-strength friction materials. These friction materials are usually sintered together with a steel plate, which is the steel backing.

[0003] In the widely used disc brake system, this structure allows the friction material to move freely in the caliper under the push of the brake cylinder body, and generate the necessary friction when braking to help the vehicle slow down or stop. The presence of the steel back not only makes the installation and replacement of the brake pads more convenient, but also ensures the effectiveness and safety of the brake system.

[0004] In the publication number CN205008944U, there is recorded a kind of automobile drum-type special-bend brake pad processing loading rack, which can push the stacked special-bend brake pads into the processing machine for drilling processing regularly through the telescopic cylinder under the control of the numerical control system; however, the above patent content realizes the loading process by fixing the brake pad loading rack during the loading process, and it is difficult to make adaptive adjustments according to the actual situation of the brake pad. It only performs single-group material selection for the steel back in the superimposed state. At the same time, since the external structure of the steel back is irregular compared with the ordinary plate, it is easy to cause the transmission deviation of the steel back, affecting the feeding quality and efficiency of the steel back.

[0005] In view of the technical defects in this aspect, a solution is now proposed. Summary of the invention

[0011] Furthermore, sliding shafts are fixedly installed at the middle sections of the front and rear inner walls of the inverted concave sliding frame, and the front and rear two groups of sliding shafts are respectively slidably connected to the top corners on the side away from the tapered end inside the front and rear limit grooves. Limiting shafts are fixedly installed at the centers of the front and rear end surfaces of the inverted concave sliding frame, and the outsides of the front and rear two groups of limit shafts are jointly sleeved with a concave push frame, and the concave push frame is sleeved at the lower end of the limit frame, and one side of the concave push frame is connected to cylinder 1 through a push rod.

[0012] Furthermore, the front and rear end surfaces of the concave push frame are both provided with vertical grooves, the front and rear groups of the limiting shafts are respectively slidably connected to the inner walls of the vertical grooves, and a damping spring shock absorber is arranged inside the vertical grooves and at the bottom of the limiting shafts.

[0013] Furthermore, the two-way correction structure includes two groups of transverse plates, the two groups of transverse plates respectively penetrate and are slidably connected to the bottom inner wall of the material distribution frame and are located at the front and rear ends of the transverse groove, the two ends of the two groups of transverse plates respectively extend to the two side frames of the top surface of the bottom frame, the top surfaces of the two groups of transverse plates are located on one side of the material distribution frame and are respectively provided with oblique grooves, the front and rear groups of oblique grooves are mirror-symmetrical with respect to the central axis of the bottom frame, the ends of the two groups of oblique grooves are commonly slidably connected with a push rod, and the sliding blocks arranged at the two ends of the bottom surface of the push rod are respectively slidably connected inside the oblique groove, the center of one side of the push rod is connected to cylinder 2 through a push rod, and cylinder 2 is arranged at a side frame of the top surface of the bottom frame.

[0017] 1. The cylinder of the present invention pushes the concave push frame, the inverted concave slide frame and the push block to move. At this time, the push block is flush with the notch on the side of the transverse groove. During the linear movement of the inverted concave slide frame, the sliding shaft at the inner wall thereof first moves linearly along the upper end groove of the limit groove of the round structure to ensure the stable movement of the inverted concave slide frame and the push block. The push block moves along the notch on one side of the transverse groove and pushes the bottom steel back sheet to move until it moves to the conical structure end of the limit groove. The push block is pushed out from the inside of the transverse groove to complete the transfer of a single set of steel back sheets.

[0018] 2. The second cylinder of the present invention pushes the push rod to move to one side, and the two groups of sliders at the end of the push rod move along the corresponding inclined grooves respectively. The sliders move linearly and press against the inner wall of the inclined groove, thereby forcing the front and rear two groups of horizontal plates to approach each other, and the two groups of semicircular push discs one opposite to each other to approach each other. The push columns on the opposite surfaces of the two groups of semicircular push discs two first press against the front and rear curved surfaces of the steel back sheet, causing the semicircular push disc two to rotate and adapt to the pressing direction of the steel back sheet. As the front and rear two groups of semicircular push discs one approach, they gradually adapt to the front and rear curved surfaces of the steel back sheet, thereby realizing adaptive pressing of the bottom steel back sheet, forcing the steel back sheet to be centered and straightened, and facilitating the linear material removal of the push block, so as to prevent the steel back sheet from deviating or deviating from the transmission track.

[0019] At the same time, the front and rear sets of horizontal plates are brought close to each other, and the steel back sheet is continuously straightened according to the clamping steps, forcing the steel back sheet transported to the loading platform to move in a straight line, reducing the deviation of the running trajectory and further improving the steel back sheet loading efficiency.

DETAILED DESCRIPTION

[0029] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1 - Figure 7 As shown, a steel back feeder for manufacturing vehicle brake pads comprises a bottom frame 1, a material distribution frame 2 and a material feeding frame 3, wherein the material distribution frame 2 is arranged at one end of the top frame of the bottom frame 1, and the material feeding frame 3 is embedded in the top surface of the bottom frame 1 and is located at one side frame, the side section of the inner frame groove of the material distribution frame 2 is arranged in a convex structure, and rectangular opening grooves are arranged at the bottom of the two side surfaces of the material distribution frame 2;

[0031] A transverse groove is provided at the center of the bottom surface of the material distribution frame 2, and the transverse groove is connected to the inside of the rectangular opening groove. The top surface of the feeding frame 3 is flush with the bottom surface of the material distribution frame 2. A discharge mechanism 4 is provided inside the bottom frame 1 and at the lower end of the material distribution frame 2. Several groups of steel back sheets are stacked and placed inside the material distribution frame 2. The steel back sheets stacked on the bottom layer are flush with the rectangular opening groove. The stacked steel back sheets are intermittently discharged in sequence by the discharge mechanism 4, and are transported to the processing platform by the feeding frame 3.

[0032] The unloading mechanism 4 includes a limit frame 41, which is fixedly mounted on the inner wall of one side of the bottom frame 1 and located at the bottom of the material distribution frame 2, and the front and rear end surfaces of the limit frame 41 are both provided with limit grooves 42 of a round-shaped structure, and the end of each group of limit grooves 42 close to the material distribution frame 2 is arranged in a conical structure, and the end of the top surface of the material distribution frame 2 away from the inner wall of the bottom frame 1 is slidably sleeved with an inverted concave sliding frame 43, and a push block 44 is fixedly mounted at the center of the top surface of the inverted concave sliding frame 43, and the push block 44 is flush with the notch on one side of the transverse groove;

[0033] A sliding shaft 45 is fixedly installed at the middle section of the front and rear inner walls of the inverted concave sliding frame 43. The front and rear two groups of sliding shafts 45 are respectively slidably connected to the top corners of the front and rear two groups of limiting grooves 42 away from the tapered end. A limiting shaft 46 is fixedly installed at the center of the front and rear end surfaces of the inverted concave sliding frame 43. The front and rear two groups of limiting shafts 46 are commonly sleeved with a concave push frame 47 on the outside, and the concave push frame 47 is sleeved at the lower end of the limiting frame 41. One side of the concave push frame 47 is connected to a cylinder 1 48 through a push rod. Vertical grooves 49 are opened on the front and rear end surfaces of the concave push frame 47. The front and rear two groups of limiting shafts 46 are respectively slidably connected to the inner walls of the vertical grooves 49, and a damping spring shock absorber 410 is arranged inside the vertical grooves 49 and at the bottom of the limiting shaft 46;

[0034] When unloading is performed using the unloading mechanism 4, the cylinder 1 48 is started, and the push rod is used to push the concave push frame 47, the inverted concave slide frame 43 and the push block 44 to move. At this time, the push block 44 is flush with the notch on the side of the transverse groove, and during the linear movement of the inverted concave slide frame 43, the slide shaft 45 on its inner wall first moves linearly along the upper end groove of the circular structure limit groove 42 to ensure the stable movement of the inverted concave slide frame 43 and the push block 44, and the push block 44 moves along the notch on one side of the transverse groove and pushes the bottom steel back sheet to move until it moves to the conical structure end of the limit groove 42. At this time, the push block 44 is pushed out from the inside of the transverse groove to complete the transfer of a single group of steel back sheets;

[0035] It is worth noting that, during the reset process of the push block 44, since the push block 44 is flush with the notch of the horizontal groove, when the cylinder 1 48 pulls the concave push frame 47 to move in the reverse direction, the slide shaft 45 slides along the top groove of the conical end of the limiting groove 42 to the bottom end of the conical groove, and the slide shaft 45 pulls the inverted concave slide frame 43 and the push block 44 to settle, and the limiting shaft 46 also slides downward along the inside of the vertical groove 49, and the damping spring shock absorber 410 is compressed to force the inverted concave slide frame 43 to settle stably;

[0036] As the inverted concave sliding frame 43 moves linearly to the straight groove at the limit groove 42 away from the tapered end, the top of the sliding shaft 45 loses the pressure of the inner wall of the limit groove 42 and returns to the top under the rebound force of the damping spring shock absorber 410, thereby realizing the upward reset of the push block 44, and the push block 44 is again flush with the side of the horizontal groove, waiting for the next material selection. When the push block 44 returns to the top, its own position sinks and is lower than the horizontal groove, and no movement obstruction is caused.

[0037] Several groups of feeding rollers 301 are arranged at equal distances inside the feeding frame 3, the front end rotation shaft of each group of feeding rollers 301 extends to the outer wall of the feeding frame 3 and is fixedly installed with a transmission gear 302, and the outside of the several groups of transmission gears 302 is commonly sleeved with a transmission chain 303, and a motor 304 is arranged at the rear end rotation shaft of a group of feeding rollers 301 located at the border of the feeding frame 3, and the single group of steel back sheets allocated is gradually pushed out through the rectangular opening groove on the side of the material dividing frame 2, and is linearly introduced into the surface of the feeding frame 3;

[0038] As the motor 304 is started, one set of the material transfer rollers 301 and the transmission gears 302 are driven to rotate, and under the meshing action of the transmission chain 303, multiple sets of transmission gears 302 are forced to rotate simultaneously, thereby realizing the transmission of multiple sets of material transfer rollers 301 and linearly conveying and loading the steel back sheet.

[0039] Example 2: Please refer to Figure 5 - Figure 7 As shown, a bidirectional deviation-correcting structure 5 is provided on the inner wall at the bottom of the material distribution frame 2, and the bidirectional deviation-correcting structure 5 includes two groups of transverse plates 51, which respectively penetrate and are slidably connected to the inner wall at the bottom of the material distribution frame 2 and are located at the front and rear ends of the transverse grooves, and the two ends of the two groups of transverse plates 51 extend to the two side frames of the top surface of the bottom frame 1, and the top surfaces of the two groups of transverse plates 51 are located on one side of the material distribution frame 2 and are respectively provided with oblique grooves 52, and the front and rear groups of oblique grooves 52 are mirror-symmetrical with respect to the central axis of the bottom frame 1;

[0040] The ends of the two groups of inclined grooves 52 are slidably connected to a push rod 53, and the sliders arranged at the two ends of the bottom surface of the push rod 53 are slidably connected to the inside of the inclined groove 52 respectively. The center of one side of the push rod 53 is connected to a second cylinder 54 through a push rod, and the second cylinder 54 is arranged at one side frame of the top surface of the bottom frame 1;

[0041] The steps of processing the steel back sheet of a single transfer by using the bidirectional deviation correction structure 5 include: starting the second cylinder 54 to use the push rod to push the push rod 53 to move to one side, and the two sets of sliders at the end of the push rod 53 move along the corresponding inclined groove 52 respectively, and the sliders move linearly and press against the inner wall of the inclined groove 52, thereby forcing the front and rear sets of the horizontal plates 51 to approach each other and move to the front and rear ends of the bottom steel back sheet located in the material distribution frame 2 respectively;

[0042] Semicircular stop plates 55 are hinged at the middle sections of the opposite surfaces of the two sets of horizontal plates 51 and at one end away from the stop rod 53. The two sets of semicircular stop plates 55 corresponding to the front and rear are mirror-symmetrical with respect to the central axis of the material distribution frame 2. The two sets of semicircular stop plates 55 located at one end of the two sets of horizontal plates 51 are respectively located at the front and rear ends of the top of the feeding frame 3.

[0043] The plane end of the semicircular support plate 1 55 extends to the outside of the horizontal plate 51, and the semicircular support plate 2 56 is hinged on both sides of the plane end of the semicircular support plate 1 55, and the plane end of the semicircular support plate 2 56 extends to the outside of the semicircular support plate 2 56. The two sides of the plane end of the semicircular support plate 2 56 are respectively embedded with support columns 57 for rotation connection, and one side column of the support column 57 extends to the outside of the semicircular support plate 2 56.

[0044] The two groups of semicircular abutment plates 55 facing each other approach each other, and the abutment columns 57 on the opposite sides of the two groups of semicircular abutment plates 56 first press against the front and rear curved surfaces of the steel back sheet, so that the semicircular abutment plates 56 rotate to adapt to the pressing direction of the steel back sheet. As the two groups of semicircular abutment plates 55 approach each other, they gradually adapt to the front and rear curved surfaces of the steel back sheet, thereby achieving adaptive pressing of the bottom steel back sheet, forcing the steel back sheet to be centered and straightened, and facilitating the linear material removal of the push block 44, so as to prevent the steel back sheet from deviating or leaving the transmission track.

[0045] Before material selection, the steel back sheet is centered and straightened, and then the cylinder 2 54 is used to pull the push rod 53 to move, forcing the two groups of sliders at the end of the push rod 53 to move in opposite directions along the corresponding inclined groove 52 respectively. The sliders move in a straight line and press against the inner wall of the inclined groove 52, forcing the front and rear groups of cross plates 51 to move away from each other and away from the bottom steel back sheet respectively, so as to reduce the obstruction to the steel back sheet when selecting materials. This structure can adapt to the pressing and clamping according to the front and rear curves of the steel back sheet to assist in centering the steel back sheet, reduce damage to the steel back sheet, and prevent the steel back sheet from being offset during the material selection process and detaching from the surface of the feed frame 3.

[0046] It is worth mentioning that since the end of the transverse plate 51 extending to the front and rear of the feed frame 3 is also provided with a semicircular abutment plate 55 component, the steel back sheet introduced into the surface of the feed frame 3 by shifting the material also uses the front and rear two groups of transverse plates 51 to approach each other, and the steel back sheet is continuously straightened according to the above-mentioned adaptive clamping steps, thereby forcing the steel back sheet transported to the loading platform to move in a straight line, reducing the deviation of the running trajectory and further improving the loading efficiency of the steel back sheet.

[0047] When the present invention is used, firstly, a plurality of groups of steel back sheets are stacked and placed inside the material distribution frame 2, and the steel back sheets stacked at the bottom layer are flush with the rectangular opening grooves, and the stacked steel back sheets are intermittently discharged in sequence by the unloading mechanism 4, and transported to the processing platform by the feeding frame 3;

[0048] The start cylinder 2 54 uses the push rod to push the push rod to move to one side, and the two groups of sliders at the end of the lever 53 move along the corresponding inclined groove 52 respectively, and the sliders move linearly and press the inner wall of the inclined groove 52, thereby forcing the front and rear groups of the horizontal plates 51 to approach each other, and move toward the front and rear ends of the bottom steel back sheet located in the material distribution frame 2 respectively, and the front and rear opposing groups of the semicircular disc 1 55 approach each other, and the opposing columns 57 of the two groups of the semicircular disc 2 56 first press against the front and rear curved surfaces of the steel back sheet, so that the semicircular disc 2 56 rotates to adapt to the pressing direction of the steel back sheet, and as the front and rear groups of the semicircular disc 1 55 approach, they gradually adapt to the front and rear curved surfaces of the steel back sheet, thereby realizing adaptive pressing on the bottom steel back sheet, forcing the steel back sheet to be centered and straightened;

[0049] Then, the unloading mechanism 4 is used to unload the material. The cylinder 1 48 pushes the concave push frame 47, the inverted concave slide frame 43 and the push block 44 to move. At this time, the push block 44 is flush with the notch on the side of the transverse groove. During the linear movement of the inverted concave slide frame 43, the slide shaft 45 on its inner wall first moves linearly along the upper end groove of the round-shaped structure limit groove 42 to ensure the stable movement of the inverted concave slide frame 43 and the push block 44. The push block 44 moves along the notch on one side of the transverse groove and pushes the bottom steel back sheet to move until it moves to the conical structure end of the limit groove 42 and the push block 44 is pushed out from the inside of the transverse groove, thereby completing the transfer of a single group of steel back sheets.

[0050] Finally, the single group of steel back sheets allocated is gradually pushed out through the rectangular opening groove on the side of the material dividing frame 2, and is linearly introduced into the surface of the feed frame 3. As the motor 304 is started, one group of feed rollers 301 and the transmission gear 302 are driven to rotate, and under the meshing action of the transmission chain 303, multiple groups of transmission gears 302 are forced to rotate at the same time, thereby realizing the transmission of multiple groups of feed rollers 301 and the linear conveying and feeding of the steel back sheets.

[0051] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
