[0002] The comprehensive index testing of the parallelism and verticality of the outer arc of the brake assembly is directly related to the braking performance of the whole vehicle. Each OEM has rigid requirements for the parallelism and verticality of the outer arc of the product, the shoe clearance and the symmetry of the product, which has become an industry indicator for measuring the key quality of the product. At present, each brake manufacturer makes comprehensive inspection tools for different products for inspection. If the inspection tools are not universal, a lot of labor costs and manufacturing costs will be wasted, and the operation will be inconvenient, the inspection accuracy will fail quickly, and the inspection error will be large.

[0003] The Chinese utility model patent with the publication number CN205642196U discloses a brake inspection fixture. It includes a base plate, on which a center pin and a dial indicator fixing column are vertically arranged, a support sleeve for supporting the brake is sleeved on the center pin, a brake mounting surface is reserved on the upper part of the support sleeve, and an alignment cone sleeve (the diameter of the lower end is smaller than the diameter of the upper end) is provided on the upper part of the brake mounting surface of the support sleeve and sleeved on the center pin; during inspection, the brake is installed on the brake mounting surface, the alignment cone sleeve cooperates with the support sleeve to clamp the brake, a dial indicator that can slide on the dial indicator fixing column is sleeved on the dial indicator fixing column, the dial indicator is fixed on the dial indicator fixing column by bolts, and the detection end of the dial indicator contacts the brake.

[0004] This type of brake gauge can only handle brakes of a single specification. Summary of the invention

[0005] The object of the present invention is to provide a universal inspection tool suitable for comprehensive inspection of various brakes, so as to solve at least one of the above-mentioned technical problems.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A universal test fixture suitable for comprehensive testing of various brakes, including:

[0008] Workbench;

[0009] A plurality of positioning plates installed on the workbench, wherein the plurality of positioning plates are coaxially connected in sequence, and the diameters of the plurality of positioning plates gradually increase in a direction close to the workbench, and the diameters of the same positioning plate are consistent;

[0010] A detection component is installed on the workbench and is used for brake detection.

[0011] The present invention provides a workbench for installing a positioning disk and a detection component, and the positioning disk is used for positioning the brake. The positioning disk cooperates with the positioning hole on the brake assembly, and the positioning disk is placed in the positioning hole to realize the placement and positioning of the brake. A positioning disk of one specification corresponds to a positioning hole of one specification. By providing multiple positioning disks, the present invention can correspond to positioning holes of various specifications, and thus can correspond to brake assemblies of various specifications. The present invention provides multiple coaxially connected positioning disks, and the positioning disks are stacked. On the premise of being able to simultaneously match brake assemblies of various specifications, the space of the workbench can be reasonably utilized without increasing the occupied area of ​​the workbench. Along the direction approaching the workbench, the diameters of the different positioning disks gradually increase, so that brake assemblies of different specifications can be smoothly matched with their corresponding positioning disks without being blocked by positioning disks of other specifications. After the brake assembly is positioned by the positioning disk, subsequent detection is performed by the provided detection component.

[0012] Furthermore, the plurality of positioning plates are integrally formed to form a positioning portion, and the plurality of positioning plates form a whole, which is easy to process and can also enhance the structural strength.

[0013] Furthermore, a positioning spindle is vertically installed on the workbench, and a mounting hole is opened along the axial direction of the end face of the positioning part close to the workbench, and the positioning spindle is inserted into the mounting hole to be coaxially connected with the positioning plate; the present invention uses the mounting hole to install the positioning part on the positioning spindle, and uses the positioning spindle to install the positioning part on the workbench, so as to facilitate the replacement of positioning parts of different specifications to match brake assemblies of more specifications.

[0014] Furthermore, the positioning core shaft is rotatably connected to the workbench via a bearing. By rotatably connecting the positioning core shaft to the workbench, the brake assembly, the positioning part and the positioning core shaft can remain relatively still during detection, thereby reducing wear and loss on the brake assembly and protecting the positioning part and the positioning core shaft. The worn parts are the bearings, which are standard parts and are easy to replace, thereby reducing the cost of use.

[0015] Furthermore, the bearing is a tapered roller bearing, which can eliminate axial and radial movement when the brake assembly rotates, making the detection data more accurate.

[0016] Furthermore, the mounting hole is set through, and the end face of the positioning core shaft is provided with a threaded hole coaxial with the positioning core shaft, and the threaded inner surface of the threaded hole is connected with an upper pressure block, and the upper pressure block is pressed against the positioning part. The upper pressure block is used to press the positioning part onto the positioning core shaft to prevent the positioning part from moving up and down, thereby improving its stability. The upper pressure block can also be rotated to drive the positioning core shaft to rotate, thereby driving the brake assembly to rotate, which is used for comprehensive detection of the brake assembly. Because the positioning core shaft is directly rotated by the upper pressure block, and force is applied from the center axis of the positioning core shaft, the whole device can be subjected to more uniform force, the brake assembly rotates more smoothly, and its detection accuracy is higher. The positioning core shaft rotates smoothly, and the corresponding wear of the whole device is also smaller, making the device more durable.

[0017] Furthermore, a supporting portion is protruded from the outer peripheral wall of the positioning core shaft, and the positioning portion is located on a side surface of the workbench, and one end of the positioning portion close to the workbench is pressed against the supporting portion. The provided supporting portion is used to support the positioning portion, and then supports the brake assembly, so that the positioning portion does not need to support the brake assembly through the friction between the positioning portion and the positioning core shaft, and the friction between the positioning portion and the positioning core shaft can be appropriately reduced. When the positioning core shaft rotates, it is sufficient to drive the positioning portion and the brake assembly to rotate together. The friction between the positioning portion and the positioning core shaft is reduced, so that the positioning portion can be replaced more easily.

[0018] Furthermore, one end of the positioning portion close to the workbench protrudes toward the workbench to form an extension portion, and the extension portion is pressed against the supporting portion. The extension portion is provided to increase the distance between the positioning portion and the workbench, so that a certain space is left between the positioning portion and the workbench for placing the brake assembly.

[0019] Furthermore, a reinforcement block is fixed to one side of the workbench, the positioning mandrel passes through the reinforcement block and is rotatably connected to the reinforcement block. By providing the reinforcement block, the connection strength between the positioning mandrel and the workbench is strengthened, the stability of the positioning mandrel during rotation is improved, and the detection accuracy of the brake assembly is improved. An external thread is provided at one end of the positioning mandrel close to the reinforcement block, and a lower nut is threadedly connected to the external thread. The lower nut is screwed until it is pressed against the reinforcement block, so that the positioning mandrel and the reinforcement block can be fixed to prevent the positioning mandrel from rotating, thereby facilitating detection.

[0020] Specifically, the detection component includes a height dial indicator, which is used to detect comprehensive indicators such as parallelism and verticality of the outer arc of the brake assembly.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention provides a workbench for installing a positioning disk and a detection component, and the positioning disk is used for positioning the brake. The positioning disk cooperates with the positioning hole on the brake assembly, and the positioning disk is placed in the positioning hole to realize the placement and positioning of the brake. A positioning disk of one specification corresponds to a positioning hole of one specification. By providing multiple positioning disks, the present invention can correspond to positioning holes of various specifications, and thus can correspond to brake assemblies of various specifications. The present invention provides multiple coaxially connected positioning disks, and the positioning disks are stacked. On the premise of being able to simultaneously match brake assemblies of various specifications, the space of the workbench can be reasonably utilized without increasing the occupied area of ​​the workbench. Along the direction approaching the workbench, the diameters of the different positioning disks gradually increase, so that brake assemblies of different specifications can be smoothly matched with their corresponding positioning disks without being blocked by positioning disks of other specifications. After the brake assembly is positioned by the positioning disk, subsequent detection is performed by the provided detection component. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0027] like Figure 1 and Figure 2 As shown, this embodiment provides a universal inspection tool suitable for comprehensive inspection of various brakes, including:

[0028] A horizontally arranged workbench 1, wherein the bottom surface of the workbench 1 is provided with a plurality of supporting legs, and the number of the supporting legs is preferably four;

[0029] A plurality of positioning plates 201 of different specifications are installed on the workbench 1 in the horizontal direction, and the plurality of positioning plates 201 are coaxially connected in sequence and stacked; from top to bottom, the diameters of the plurality of positioning plates 201 gradually increase, and the diameters of the same positioning plate 201 are consistent;

[0030] The detection component 3 is installed on the workbench 1 and is used for brake detection.

[0031] The present invention uses a workbench 1 to install a positioning disc 201 and a detection component 3. The positioning disc 201 is used to position the brake. The positioning disc 201 cooperates with the positioning port on the brake assembly 10. The positioning disc 201 is placed in the positioning port to achieve the placement and positioning of the brake. A positioning disc 201 of one specification corresponds to a positioning port of one specification. By setting a plurality of positioning discs 201, the present invention can correspond to positioning ports of various specifications, and thus can correspond to brake assemblies 10 of various specifications. The present invention uses a plurality of positioning discs 201 coaxially connected in sequence to form a plurality of positioning discs 201. The positioning disks 201 are stacked and arranged, and under the premise of being able to match brake assemblies 10 of various specifications at the same time, the space of the workbench 1 can be reasonably utilized without increasing the occupied area of ​​the workbench 1; along the direction approaching the workbench 1, the diameters of the different positioning disks 201 gradually increase, so that brake assemblies 10 of different specifications can be smoothly matched with their corresponding positioning disks 201 without being blocked by positioning disks 201 of other specifications; after the brake assembly 10 is positioned by the positioning disk 201, subsequent detection is performed through the set detection component 3.

[0032] Furthermore, the plurality of positioning plates 201 are integrally formed to form a positioning portion 2. The plurality of positioning plates 201 form a whole, which is easy to process and can also enhance the structural strength.

[0033] Furthermore, a positioning spindle 4 is vertically installed on the workbench 1, and a mounting hole 202 is provided along the axial direction of the end face of the positioning part 2 close to the workbench 1, and the positioning spindle 4 is inserted into the mounting hole 202 to be coaxially connected with the positioning plate 201; the mounting hole 202 provided by the present invention is used to install the positioning part 2 on the positioning spindle 4, and the positioning spindle 4 is used to install the positioning part 2 on the workbench 1, so as to facilitate the replacement of positioning parts 2 of different specifications to match brake assemblies 10 of more specifications; preferably, the positioning part 2 and the positioning spindle 4 can be connected by a flat key, and keyways are provided on the inner wall of the mounting hole 202 and the outer periphery of the positioning spindle 4, and the insertion of the flat key can realize the axial torque transmission between the positioning spindle 4 and the positioning part 2, so that when the positioning spindle 4 rotates, it can drive the positioning part 2 to rotate together, or when the positioning part 2 rotates, it drives the positioning spindle 4 to rotate together; preferably, the positioning spindle 4 and the positioning part 2 can also be tightly connected by an interference fit.

[0034] Furthermore, the positioning spindle 4 is rotatably connected to the workbench 1 via the bearing 6. By rotatably connecting the positioning spindle 4 to the workbench 1, the brake assembly 10, the positioning portion 2 and the positioning spindle 4 can remain relatively still during detection, thereby reducing wear and tear on the brake assembly 10 and protecting the positioning portion 2 and the positioning spindle 4. The worn part is the bearing 6, which is a standard part and is easy to replace, thereby reducing the cost of use.

[0035] Furthermore, the bearing 6 is a tapered roller bearing 6, which can eliminate axial and radial movement when the brake assembly 10 rotates, making the detection data more accurate.

[0036] Furthermore, the mounting hole 202 is set through, and the end face of the positioning spindle 4 is provided with a threaded hole 5 coaxial with it. The threaded hole 5 is internally threadedly connected with an upper pressure block, and the upper pressure block is pressed against the positioning part 2. The upper pressure block is used to press the positioning part 2 onto the positioning spindle 4 to prevent the positioning part 2 from moving up and down, thereby improving its stability. The upper pressure block can also be rotated to drive the positioning spindle 4 to rotate, thereby driving the brake assembly 10 to rotate, which is used for comprehensive detection of the brake assembly 10, because the positioning spindle 4 is directly rotated by the upper pressure block, and force is applied from the center axis of the positioning spindle 4. Therefore, the force on the entire device can be more evenly distributed, the brake assembly 10 rotates more smoothly, and its detection accuracy is higher. The positioning spindle 4 rotates smoothly, and the corresponding wear of the entire device is also smaller, making the device more durable; preferably, the threaded hole 5 is opened on the end face of the top end of the positioning spindle 4.

[0037] Furthermore, a support portion 7 is protruded from the outer peripheral wall of the positioning core shaft 4, and the positioning portion 2 is located on a side surface of the workbench 1. One end of the positioning portion 2 close to the workbench 1 is pressed against the support portion 7. The support portion 7 is provided to support the positioning portion 2, and then support the brake assembly 10, so that the positioning portion 2 does not need to support the brake assembly 10 through the friction between the positioning portion 2 and the positioning core shaft 4. The friction between the positioning portion 2 and the positioning core shaft 4 can be appropriately reduced. When the positioning core shaft 4 rotates, it is sufficient to drive the positioning portion 2 and the brake assembly 10 to rotate together. The friction between the positioning portion 2 and the positioning core shaft 4 is reduced, so that the positioning portion 2 can be replaced more easily.

[0038] Furthermore, one end of the positioning portion 2 close to the workbench 1 protrudes toward the workbench 1 to form an extension portion 8, and the extension portion 8 is pressed against the support portion 7. The extension portion 8 is used to increase the distance between the positioning portion 2 and the workbench 1, so that a certain space is left between the positioning portion 2 and the workbench 1 for placing the brake assembly 10.

[0039] Furthermore, a reinforcement block 9 is fixed to one side of the workbench 1, and the positioning spindle 4 passes through the reinforcement block 9 and is rotatably connected to the reinforcement block 9. By setting the reinforcement block 9, the connection strength between the positioning spindle 4 and the workbench 1 is strengthened, the stability of the positioning spindle 4 during rotation is improved, and the detection accuracy of the brake assembly 10 is improved. Preferably, the positioning spindle 4 and the reinforcement block 9 are also rotatably connected through a tapered roller bearing 6. The top end of the positioning spindle 4 is located on the top surface of the workbench 1, and the bottom end is located on the bottom surface of the workbench 1. The reinforcement block 9 is installed on the bottom surface of the workbench 1, which is conducive to the stable rotation of the positioning spindle 4; the end of the positioning spindle 4 close to the reinforcement block 9 is provided with an external thread, and a lower nut is threadedly connected to the external thread. The lower nut is screwed until it is pressed against the reinforcement block 9, so that the positioning spindle 4 can be fixed to the reinforcement block 9 to prevent the positioning spindle 4 from rotating, which is convenient for detection.

[0040] Specifically, the detection component 3 includes a height dial gauge 301, which is used to detect comprehensive indicators such as the parallelism and verticality of the outer arc of the brake assembly 10.

[0041] It should be noted that although the present invention is disclosed as above by specific embodiments, the above embodiments are not intended to limit the present invention. Ordinary technicians in this field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
