Description

Technical Field

[0001] The invention relates to the technical field of disc brake disc processing, and in particular to a single-end surface grinder precision grinding device for a disc brake disc. Background Art

[0002] The disc brake, also known as the brake disc or brake disc, is one of the key components in the vehicle's braking system. The disc brake disc works with the brake caliper and brake pads to convert the vehicle's kinetic energy into heat energy through friction, thereby slowing down or stopping the vehicle. The disc brake disc is usually a round metal disc with a center hole in the middle for connecting and installing to the wheel hub. The areas on both sides of the center hole are smooth to generate friction with the brake pads, and various shapes of through holes are opened in this area for heat dissipation and weight reduction, such as round holes and fan-shaped holes.

[0003] During the processing of disc brake discs, it is necessary to perform precision grinding on the disc brake areas on both sides of the center hole of the disc brake disc to ensure that the flatness of the surface meets the use requirements, thereby ensuring the performance and safety of the brake system. At present, during precision grinding, the disc brake disc is first fixed and clamped through the center hole, and then ground through existing external grinding equipment (such as angle grinders and brake disc grinders, etc.). However, at present, a method of grinding multiple disc brake discs at one time is mostly adopted. This method is to place the disc brake discs in sequence first, and then fix and lock them independently. Therefore, when multiple disc brake discs are clamped, it is necessary to repeat the fixing and locking steps multiple times. The operation process is cumbersome, which is not conducive to the batch grinding operation of disc brake discs. In addition, independent locking makes it difficult to ensure the uniformity of the fixation of the disc brake discs to be processed, and the fixing stability also needs to be improved.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, a single-end surface grinder precision grinding device for a disc brake disc comprises: an operating platform 1, a circular platform plate 2 is fixedly provided on the upper end surface of the operating platform 1, the upper end surface of the platform plate 2 slides up and down and is penetrated by three groups of column groups with vertical axes, the column group comprises two mounting rods 3, the upper end surfaces of the two mounting rods 3 in the same group are jointly fixed with a supporting plate 4 for placing the disc brake disc, a lifting hydraulic system is provided on the operating platform 1, a lifting column 5 with a vertical axis is provided in the lifting hydraulic system, a circular plate 6 is fixedly provided on the lower end surface of the lifting column 5, a grinding disc 7 corresponding to the supporting plate 4 is rotatably provided on the circular plate 6 through a rotating sleeve 63; a reinforcing member for improving the connection strength is jointly fixedly provided between the rotating sleeve 63 and the corresponding grinding disc 7.

[0037] like Figure 1 , Figure 2 , Figure 4, Figure 5 and Figure 7 As shown, the platform plate 2 is provided with a clamping mechanism 8, which includes a spreading block 80 and a spreading column 81. The support plate 4 is provided with three spreading blocks 80 and three spreading columns 81 along its radial sliding direction, and the three spreading blocks 80 and three spreading columns 81 are evenly distributed along the circumference of the corresponding support plate 4, and the spreading columns 81 and the spreading blocks 80 are alternately distributed. The clamping mechanism 8 also includes a driving unit 83 for driving the spreading blocks 80 and the spreading columns 81 to spread and clamp the disc brake disc. The platform plate 2 is provided with a locking unit 9 for locking the disc brake disc.

[0038] The support plates 4 are supported by support blocks 80 and support columns 81 to support and clamp the disc brake disc, and are locked by locking units 9, so that two triangular stable clamping frames are formed on each support plate 4. At the same time, the three support plates 4 are distributed in a triangle and locked together in sequence to form a triangular frame.

[0039] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a driving shaft 60 with a vertical axis is rotatably provided on the circular plate 6, and the driving shaft 60 is connected to an external motor (not shown in the figure). The driving shaft 60 is connected to a rotating sleeve 63 through a sprocket chain transmission. A fixing plate 61 is fixedly provided on the lower end surface of the mounting rod 3, and a spring 62 mounted on the mounting rod 3 is fixedly provided between the fixing plate 61 and the platform plate 2.

[0040] During operation, the staff first places the disc brake disc to be ground on the supporting plate 4, with the grinding surface of the disc brake disc facing upwards. Next, the opening block 80 is located in the center hole of the corresponding disc brake disc, and the opening column 81 is located in the corresponding weight-reducing hole on the disc brake disc. Then, the lifting hydraulic system works to make the lifting column 5 drive the circular plate 6 to move downward. During the downward movement, the supporting plate 4 drives the disc brake disc thereon to move downward synchronously. The spring 1 62 is stretched, and the opening block 80 and the opening column 81 in the clamping mechanism 8 gradually open and clamp the disc brake disc. When the supporting plate 4 and the platform plate are aligned, the opening block 80 and the opening column 81 in the clamping mechanism 8 are gradually opened and clamped. 2, the clamping process is completed, the locking unit 9 works to lock the supporting plate 4, as the lifting column 5 gradually moves downward, the grinding disc 7 is in close contact with the upper end surface of the disc brake disc, and the external motor works to drive the driving shaft 60 to rotate synchronously, so the driving shaft 60 drives the three rotating sleeves 63 and the grinding disc 7 to rotate synchronously, and the grinding disc 7 grinds the upper end surface of the disc brake disc. After the grinding operation is completed, the lifting column 5 moves up and resets, the locking unit 9 is unlocked, and the elastic force generated by the deformation of the spring 1 62 makes the supporting plate 4 move up and reset, and then the processed disc brake disc is taken out.

[0041] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the clamping mechanism 8 also includes a sliding block 1 82 and a sliding block 2 820. Three sliding blocks 1 82 and three sliding blocks 2 820 are installed on the support plate 4 in a radially sliding manner and penetrate the support plate 4. The sliding block 1 82 is fixedly connected to the support block 80, and the sliding block 2 820 is fixedly connected to the support column 81. A right-angled trapezoidal locking block 821 is fixedly provided on the upper end surface of the support block 80. The inclined surface of the locking block 821 faces upward and tilts downward in the direction away from the axis of the support plate 4. The platform plate 2 is provided with avoidance grooves 822 corresponding to the support plates 4 one by one.

[0042] like Figure 5 , Figure 7 and Figure 8 As shown, the driving unit 83 includes a U-shaped frame 830, and the lower end surface of the platform plate 2 is fixedly provided with a U-shaped frame 830 corresponding to the supporting plate 4 and located directly below the supporting plate 4, the U-shaped frame 830 is located between the corresponding mounting rods 3, and a central column 831 with a vertical axis and penetrating the horizontal section of the U-shaped frame 830 is rotatably provided on the supporting plate 4, a sliding plate 832 is slidably sleeved up and down on the central column 831, and the upper end surface of the sliding plate 832 is hinged to the sliding block 82 through a hinge bar 1.

[0043] like Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a sliding plate 833 is slidably sleeved on the center column 831, and the sliding plate 833 is located between the supporting plate 4 and the sliding plate 1 832. The sliding plate 833 is hinged to the sliding block 820 through a hinge bar 2. A spring 834 sleeved on the corresponding center column 831 is fixedly arranged between the sliding plate 833 and the sliding plate 1 832, and a through groove 835 for avoiding the hinge bar 1 is opened on the sliding block 820.

[0044] During operation, during the downward movement of the lifting column 5, the locking unit 9 is used to enable the supporting plate 4 to drive the disc brake disc thereon to move downward synchronously. During the downward movement of the supporting plate 4, the central column 831 drives the sliding plate 1 832 and the sliding plate 2 833 to move downward continuously. The sliding plate 1 832 stops moving after contacting the horizontal section of the corresponding U-shaped frame 830, and the supporting plate 4 continues to move downward. At this time, there is relative movement between the sliding plate 1 832 and the supporting plate 4. Therefore, the sliding block 1 82 is moved away from the axis of the supporting plate 4 through the hinge strip 1, and the sliding block 1 82 drives the opening block 80 thereon to open and clamp the center hole of the corresponding disc brake disc. At the same time, the locking block 821 moves to the top of the disc brake disc, and the disc brake disc is initially limited in the up and down directions through the cooperation between the locking block 821 and the supporting plate 4. Secondly, after the above-mentioned sliding plate 832 stops moving, the sliding block 82 temporarily stops moving, and then the supporting plate 4 continues to move downward. The elastic force of the set spring 2 834 is used to resist the sliding plate 2 833, so that the sliding plate 2 833 remains stationary. Therefore, the hinge strip 2 drives the sliding block 2 820 thereon to move synchronously, and the sliding block 2 820 drives the support column 81 thereon away from the axis of the supporting plate 4, and finally presses against the inner wall of the weight reduction hole. The supporting plate 4 continues to move downward, so that the spring 2 834 is compressed.

[0045] In summary, when the support plate 4 is in contact with the platform plate 2, the expansion blocks 80 and the expansion columns 81 complete the internal expansion action, the three expansion blocks 80 on the same support plate 4 complete the triangular expansion and fixation of the disc brake disc, and the three expansion columns 81 also complete the triangular expansion and fixation of the disc brake disc, and the two triangular expansion and fixation frames cooperate with each other to improve the stability of the disc brake disc clamping.

[0046] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the locking unit 9 includes a mounting bar 90, a mounting bar 90 is fixedly provided on one side of the supporting plate 4 close to the circumferential surface of the platform plate 2, a mounting bar 900 is fixedly provided on one side of the supporting plate 4 close to the center of the platform plate 2, and the overlapping parts of the three mounting bars 900 are stacked in sequence from bottom to top, and mounting holes 901 are provided on both the mounting bar 90 and the mounting bar 900, and a mounting column 902 that passes through all the mounting holes 901 on the mounting bars 900 is fixedly provided at the center position of the platform plate 2, and a plurality of bolts 903 that pass through the corresponding mounting holes 901 on the mounting bar 90 are fixedly provided on the platform plate 2, and all the bolts 903 are commonly sleeved with a locking ring 904 located above the mounting bar 90, and nuts located above the locking ring 904 are threadedly installed on the bolts 903.

[0047] like Figure 3 and Figure 4As shown, a lifting sleeve 91 is fixedly provided at the lower end of the lifting column 5 through a spring telescopic rod with a vertical axis. The inner diameter of the lower opening of the lifting sleeve 91 is the same as the diameter of the mounting column 902, and the upper end of the mounting column 902 is chamfered.

[0048] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the locking unit 9 also includes an L-shaped frame 92, and the upper end surface of the circular plate 6 is fixedly provided with an L-shaped frame 92 corresponding to the supporting plate 4 one by one, and a rotating column 920 that passes through the rotating sleeve 63 is fixedly provided on the L-shaped frame 92, and the lower end surface of the rotating column 920 is provided with a docking groove 921 that is plugged into the upper end of the corresponding center column 831.

[0049] During operation, as the circular plate 6 moves downward, the lifting sleeve 91 on the circular plate 6 moves downward and contacts the uppermost mounting bar 2 900, and the spring telescopic rod is compressed. As the circular plate 6 continues to move downward, the lifting sleeve 91 presses down all mounting bars 2 900, so that all supporting plates 4 move downward synchronously, and the inner support clamping of the disc brake disc is performed during the downward movement of the supporting plate 4. Finally, the three mounting bars 2 900 are arranged in sequence from top to bottom in a clockwise order, the mounting column 902 passes through the mounting holes 901 on all mounting bars 2 900, and the bolts 903 pass through Corresponding to the mounting hole 901 on the mounting strip 1 90, the locking ring 904 is manually mounted on the mounting hole 901, and the nut is tightened onto the corresponding bolt 903 to complete the clamping process and the final locking process of the three disc brake discs. The three mounting strips 2 900 are stacked on top of each other so that the three support plates 4 are mutually correlated and locked, which improves the stability of the support plate 4 after its own position is locked and the stability of the disc brake disc after clamping and locking, thereby improving the stability of subsequent grinding, and also improving the convenience of the operation process.

[0050] During the downward movement of the lifting sleeve 91, the mounting column 902 is inserted into the lifting sleeve 91, and at the same time, the upper end of the center column 831 is inserted into the corresponding docking groove 921 of the rotating column 920. Therefore, the lifting sleeve 91, the mounting column 902, the circular plate 6, the mounting bar 900, the supporting plate 4, the center column 831 and the rotating column 920 together form a rectangular frame. The three rectangular frames are used to improve the overall structural strength, which in turn helps to improve the stability of subsequent grinding and ensure that after the grinding wheel 7 moves down to press the disc brake, the axis of the grinding wheel 7 is in the same line with the axis of the disc brake.

[0051] like Figure 8 , Fig. 9 and Fig.11As shown, the sliding plate 1 832 and the sliding plate 2 833 are both provided with waist-shaped grooves 93, and two locking strips 930 distributed up and down are fixedly sleeved on the central column 831. The inner wall of the waist-shaped groove 93 is provided with a locking groove 931 connected thereto, and the locking groove 931 is circular.

[0052] like Figure 2 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the locking unit 9 also includes a spiral spring 94, and a spiral spring 94 is fixedly arranged between the center column 831 and the lower end of the support plate 4. Two symmetrical spiral grooves 940 are provided on the inner wall of the docking groove 921, and a mating piece 941 that cooperates with the spiral groove 940 is fixedly arranged on the upper end of the center column 831.

[0053] It should be noted that the locking strip 930 in the initial state is opposite to the waist groove 93 in the upper and lower parts, that is, the sliding plate 1 832 and the sliding plate 2 833 can move up and down along the central column 831. When the clamping of the disc brake is completed, the locking strip 930 moves into the corresponding locking groove 931 and still remains opposite to the corresponding waist groove 93 in the upper and lower parts. When the lower end surface of the supporting plate 4 contacts the platform plate 2, the clamping of the disc brake is completed and the lower end surface of the lifting sleeve 91 is pressed against the uppermost mounting strip 2 900. The sliding plates 1 832 and the sliding plates 2 833 both stop moving, and at this time the locking strip 930 is opposite to the corresponding waist groove 93. Then the circular plate 6 continues to move downward, and finally the grinding disc 7 is aligned with the disc brake. The disc is tightly attached, and the center column 831 is gradually inserted into the docking groove 921 on the corresponding rotating column 920. Through the cooperation between the spiral groove 940 and the corresponding matching piece 941, the matching piece 941 drives the corresponding center column 831 to rotate synchronously, and the spiral spring 94 is deformed. At the same time, the center column 831 drives the locking bar 930 to rotate synchronously. The locking bar 930 is staggered with the corresponding waist groove 93, and the sliding plate 1 832 and the sliding plate 2 833 are locked, and then the sliding block 1 82 and the sliding block 2 820 are locked through the two locking bars 930 on the same center column 831; in summary, after the disc brake disc is clamped internally, the clamping and locking are implemented again to improve the stability of subsequent grinding.

[0054] When the grinding operation is completed, the circular plate 6 drives the rotating column 920 to move upward. The cooperation between the spiral groove 940 and the matching piece 941 and the elastic force generated by the deformation of the spiral spring 94 make the center column 831 rotate and reset. The locking bar 930 is opposite to the corresponding waist groove 93, and the locking of the sliding block 1 82 and the sliding block 2 820 is released.
