Description

Technical Field

[0001] The utility model relates to the technical field of detection tools, in particular to a deformation detection tool for a caliper bracket. Background Art

[0002] The caliper is one of the more important components in the entire automobile braking system. It plays a role in protecting the driver and passengers. Therefore, it is necessary to carry out corresponding inspections on each component during the caliper manufacturing process to prevent deformed and unqualified products from entering the market.

[0003] The existing Chinese patent application number: 201920578975.0 discloses a deformation gauge for a caliper bracket, which is used to detect the overall size of the casting of the caliper bracket. The caliper bracket includes a main beam, a small beam, two main beam arms arranged at both ends of the main beam, and two small beam arms arranged at both ends of the small beam. A caliper handle is connected between each main beam arm and each small beam arm. It is characterized in that: the deformation gauge includes a base plate, a first detection area located on the front side of the base plate, and a second detection area located on the rear side of the base plate, the first detection area is used to detect the size of the caliper bracket being concave in the transverse direction, and the second detection area is used to detect the size of the caliper bracket being outward in the longitudinal direction.

[0004] Although the above technology has a certain degree of effect in detecting deformation of the caliper bracket when used, it does not have the effect of conveniently replacing components such as the card block used for detection. Therefore, in actual use, when the inspection fixture is accidentally dropped and damaged or the production batch is changed, the above technology cannot be quickly repaired and adapted to the use of other models of caliper brackets. Therefore, in order to solve the above technical problems, we propose a deformation inspection fixture for the caliper bracket. Utility Model Content

[0014] The utility model provides a deformation inspection tool for a caliper bracket, which has the following beneficial effects:

[0015] 1: In the utility model, the detection area is firstly used according to the type and size of the caliper bracket to be detected. At this time, each card block in the detection area is inserted into the corresponding plug-in slot in turn through the plug-in rod, and then the magnetic suction plate is pushed to abut against the lower surface of the plug-in rod through the linkage column 5. At this time, the plug-in rod is restricted by the plug-in slot in the horizontal direction and the magnetic suction plate in the vertical direction, that is, the installation and fixation of the card block is achieved through the cooperation of the magnetic suction plate and the plug-in rod; thereby, when the card block falls and deforms, the inspection fixture can be replaced in a timely and convenient manner, thereby reducing losses, and the card block can be replaced in a timely and convenient manner according to the type and size of the caliper bracket, thereby adapting to different caliper bracket deformation detection uses.

[0016] 2: The setting of the polygonal lifting column in the utility model enables the personnel to pull the force rod out from the inside of the base when driving the linkage column to rotate, thereby facilitating the rotation of the force rod. When the inspection fixture is in normal use, the force rod can be hidden inside the base by retracting the lifting column toward the inside of the linkage column, thereby facilitating the placement of the base. The setting of the anti-falling ball facilitates the avoidance of separation of the force rod from the lifting column, and can amplify the torque applied to the lifting column by the personnel's hand by moving the force rod, thereby allowing the personnel to rotate the lifting column labor-savingly and conveniently. The setting of the linkage plate facilitates the installation of the magnetic plate, and because there is a gap between the linkage plate and the installation cavity, the air in the plug-in slot can be easily discharged when the personnel insert the plug-in rod, thereby avoiding the unstable contact between the plug-in rod and the magnetic plate.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0025] Reference Figure 1-6 A deformation inspection tool for a caliper bracket comprises a base 1, a plurality of contact pieces 2 and a card block 3 arranged on the upper surface of the contact piece 2 for detecting whether the bracket is deformed. The card block 3 is each component in the first detection area and the second detection area in the prior art (application number: 201920578975.0), that is, a plurality of card blocks 3 of different shapes constitute the first detection area and the second detection area; a mounting cavity is arranged inside the lower side of the base 1 and a mounting plate 4 is fixed at the opening of the mounting cavity, a linkage column 5 is threadedly installed in the middle of the mounting plate 4, and a magnetic plate 6 is rotatably arranged at one end of the linkage column 5 located inside the mounting cavity, a plurality of rectangular plug-in grooves 7 are arranged on the upper surface of the base 1 corresponding to the magnetic plate 6, and a matching plug-in rod 8 is arranged on the lower surface of the contact piece 2 corresponding to the plug-in groove 7, and the lower end of the plug-in rod 8 abuts against the upper surface of the magnetic plate 6, and the lower end of the linkage column 5 is located below the mounting plate 4 and is provided with a force rod 9. Example

[0026] Reference Figure 1-6 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0027] The lower end of the linkage column 5 is provided with a card slot with a polygonal cross section and a lifting column 10 is slidably installed. The lower end of the lifting column 10 extends to the bottom of the linkage column 5 and is connected to the force rod 9. The setting of the polygonal lifting column 10 allows the personnel to pull the force rod 9 out from the inside of the base 1 when driving the linkage column 5 to rotate, so as to facilitate the force rod 9 to rotate in a circle. When the inspection tool is in normal use, the lifting column 10 can be retracted into the linkage column 5 so that the force rod 9 is hidden inside the base 1, which is convenient for the placement of the base 1. The force rod 9 and the lifting column 10 are slidably connected, and anti-falling balls 11 are provided at both ends of the force rod 9. The setting of the anti-falling balls 11 is convenient to prevent the force rod 9 from being separated from the lifting column 10, and the torque applied to the lifting column 10 by the personnel's hand can be amplified by moving the force rod 9, so that the personnel can save effort and conveniently rotate the lifting column 10.

[0028] A linkage plate 12 is installed on the lower surface of the magnetic plate 6, and the upper end of the linkage column 5 is rotatably installed in the middle of the linkage plate 12. Guide components are provided at both ends of the linkage plate 12. The outer ring surface of the linkage plate 12 is spaced apart from the inner wall of the installation cavity. The arrangement of the linkage plate 12 facilitates the installation of the magnetic plate 4. Since there is a gap between the linkage plate 12 and the installation cavity, the air in the plug-in slot 7 can be easily discharged when the personnel insert the plug-in rod 8, so as to avoid the unstable contact between the plug-in rod 8 and the magnetic plate 4. The guide component includes a guide column 13 and a guide protrusion 14. The guide protrusion 14 is arranged at both ends of the linkage plate 12. Receiving grooves are provided at both ends of the cavity, and the guide column 13 is installed in the receiving groove and is slidably connected with the guide protrusion 14. The setting of the guide protrusion 14 and the guide rod 13 makes the linkage plate 12 stable when it is lifted and lowered, so that it is convenient for the linkage column 5 to drive the linkage plate 12 to lift and lower; holding frames 15 are provided at both ends of the base 1, and the lower surface of the base 1 is provided with anti-slip pads 16. The setting of the holding frame 15 is convenient for personnel to hold and move the inspection tool; installation openings are provided at both ends of the lower surface of the base 1, and magnetic strips 17 are installed in the installation openings. The setting of the magnetic strip 17 makes it convenient to use the inspection tool on a metal desktop with magnetic attraction, and the inspection tool can be more stable and not easy to move at will.

[0029] Principle and advantages of use: During use, the utility model is provided with a plurality of card blocks 3 of different shapes, and the specific shape of the card blocks 3 can be set in a targeted manner according to the shape and size of the caliper bracket to be detected, so that a plurality of detection areas that can be used for deformation detection of different caliper brackets are formed by a plurality of card blocks 3. Subsequently, when using, personnel first use the targeted detection area according to the type and size of the caliper bracket to be detected. At this time, each card block 3 in the detection area is inserted into the corresponding plug-in slot 7 in sequence through the plug-in rod 8 until the contact piece 2 abuts against the upper surface of the base 1. Further, personnel slightly flip the base 1 and rotate the force rod 9. When the force rod 9 rotates, it drives the linkage column 5 to rotate. When the linkage column 5 rotates, it pushes the magnetic plate 4 to move upward under the action of the mounting plate 4 and the thread until the magnetic plate 4 abuts against the lower surface of the plug-in rod 8. At this time, the plug-in rod 8 is horizontally restricted by the plug-in slot 7, and its vertical direction is restricted by the magnetic plate 4, that is, the installation and fixation of the card block 3 is achieved through the cooperation of the magnetic plate 4 and the plug-in rod 8.

[0030] In summary, with the mutual cooperation of various components, when this solution is used, if a magnetic suction plate 4 with strong suction force is selected, the magnetic suction plate 4 is controlled to contact or fall off with the plug-in rod 8 through the force rod 9. If a magnetic suction plate 4 with medium suction force is selected, the person can directly hold the card block 3 by hand to pull out the plug-in rod 8 from the plug-in slot 7. That is, through the setting of the magnetic suction plate 4, the plug-in slot 7 and the contact rod 8, the person can easily install and disassemble the card block 3, so that when the card block 3 falls and deforms, the inspection fixture can be replaced in a timely and convenient manner to reduce the loss. The card block 3 can also be replaced in a timely and convenient manner according to the type and size of the caliper bracket, so as to adapt to different caliper bracket deformation detection uses.

[0031] It should be further explained that the setting of the polygonal lifting column 10 allows the personnel to pull the force rod 9 out from the inside of the base 1 when driving the linkage column 5 to rotate, thereby facilitating the rotation of the force rod 9 in a circle. When the inspection tool is in normal use, the lifting column 10 can be retracted into the linkage column 5 so that the force rod 9 is hidden inside the base 1, thereby facilitating the placement of the base 1. The setting of the anti-falling ball 11 is convenient for preventing the force rod 9 from being separated from the lifting column 10, and can amplify the personnel by moving the force rod 9. The torque applied to the lifting column 10 by the hand allows the personnel to rotate the lifting column 10 effortlessly and conveniently; the setting of the linkage plate 12 facilitates the installation of the magnetic plate 4, and because there is a gap between the linkage plate 12 and the installation cavity, the air in the plug-in slot 7 can be easily discharged when the personnel insert the plug-in rod 8, so as to avoid the unstable contact between the plug-in rod 8 and the magnetic plate 4; the setting of the magnetic strip 17 makes it easier to use the inspection tool on a metal desktop with magnetic attraction, so that the inspection tool can be more stable and not easy to move at will.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
