Technical Field

[0001] This application relates to the technical field of paint detection equipment, and in particular to a rubber friction paint detection device. Background Art

[0002] After applying paint to a test sample, it is necessary to detect the wear resistance of the paint. Currently, the detection method usually uses an alcohol rubber wear resistance testing machine. By repeatedly rubbing the rubber on the paint surface, the wear resistance of the paint can be detected.

[0003] Chinese Patent with application number CN202322626054.6 discloses a rubber alcohol wear resistance testing machine that is convenient for replacing the rubber. It includes a testing machine. On the left and right sides of the top of the testing machine, support rods are fixedly connected. The top of the support rods is fixedly connected with a connection box. The right side of the connection box is movably connected with a screw rod through a bearing seat. The right side of the screw rod is fixedly connected with a turntable, and the left side of the screw rod penetrates into the interior of the connection box.

[0004] In the above solution, it is necessary to rotate the screw rod to drive the arc-shaped clamping plate to move, and then the rubber can be disassembled and installed. The diameter of the turntable at the head of the screw rod is usually set according to requirements, and there may be a situation where the turntable is too small, resulting in more troublesome rotation of the screw rod and affecting the disassembly and installation of the rubber.

[0005] Therefore, a new technical solution needs to be proposed to solve the above problems. Utility Model Content

[0006] In order to make the replacement of the rubber eraser more convenient, this application provides a rubber friction paint detection device.

[0007] A rubber friction paint detection device provided by this application adopts the following technical solution:

[0008] A rubber friction paint detection device includes a base, a support plate slidably arranged on the base, a driving component for driving the support plate to reciprocate, a support rod vertically sliding on the base, and a connecting component for connecting the rubber. The connecting component is arranged below the support rod. The connecting component includes a connecting sleeve arranged at the lower end of the support rod, a magnetic member arranged in the connecting sleeve, a connecting plate magnetically attracted to the magnetic member, and a connecting needle coaxially arranged on the connecting plate. One end of the connecting sleeve away from the support rod is open. The magnetic member is fixed on the end face of the inner cavity of the connecting sleeve. The side wall of the connecting plate can be attached to the inner wall of the connecting sleeve and slide in the connecting sleeve. The magnetic member can be attracted to the connecting plate. The rubber can abut against the end face of the connecting plate away from the magnetic member. The connecting needle is inserted into the rubber.

[0009] By adopting the above technical solution, when replacing the eraser, directly pinch the eraser to separate the connecting plate from the magnetic part and take it out of the connecting sleeve. Then, pinch the connecting plate to detach the eraser from the connecting pin. After that, connect the new eraser to the connecting pin, insert the connecting plate into the connecting sleeve and attract it with the inner magnetic part to complete the replacement of the eraser. When replacing the eraser, only need to unplug the eraser and then plug it in to achieve the replacement of the eraser, thus making the replacement of the eraser more convenient.

[0010] Optionally: The connecting pin penetrates through the connecting plate, and an anti - detachment block is fixed on the end face of the connecting pin far from its tip, and the anti - detachment block can abut against the connecting plate.

[0011] By adopting the above technical solution, before inserting the connecting pin into the eraser, make the side wall of the connecting plate flush with the side wall of the eraser, and then insert the connecting pin into the eraser, so that the axis of the eraser can coincide with the axis of the connecting plate, making the process of inserting the connecting plate into the connecting sleeve more convenient.

[0012] Optionally: A receiving groove is coaxially opened on the end face of the connecting plate close to the magnetic part, and the anti - detachment block sinks into the receiving groove.

[0013] By adopting the above technical solution, when the connecting plate is adsorbed on the magnetic part, the anti - detachment block can sink into the receiving groove, so that the anti - detachment block will not affect the adsorption between the magnetic part and the connecting plate.

[0014] Optionally: A connecting ring is coaxially fixed at one end of the connecting plate far from the connecting sleeve, the outer wall of the connecting ring abuts against the inner wall of the connecting sleeve, and the eraser abuts against the inner wall of the connecting ring.

[0015] By adopting the above technical solution, when the eraser abuts against the connecting plate and limits the relative position between the connecting plate and the eraser, the position of the eraser is guided by the connecting ring, so that the axis of the eraser is more easily aligned with the axis of the connecting plate.

[0016] Optionally: An abutting ring is coaxially fixed at a position on the outer wall of the connecting ring far from the connecting sleeve, the abutting ring abuts against one end of the connecting sleeve far from the support rod, and the diameter of the abutting ring is larger than the outer diameter of the connecting sleeve.

[0017] By adopting the above technical solution, when it is necessary to take out the connecting plate from the connecting sleeve, directly apply force to the abutting ring to move the connecting plate, preventing the situation that the eraser is directly detached from the connecting pin due to directly applying force to the eraser.

[0018] Optionally: An installation seat is arranged on the base, the support rod slides through the installation seat, and a positioning block is coaxially fixed on the support rod, and both the upper and lower ends of the positioning block can abut against the upper end of the installation seat.

[0019] By adopting the above technical solution, the support rod that is not needed can be pulled out from the mounting base and rotated by 180 degrees, so that the original upper end of the support rod is inserted downward into the mounting base, preventing the support rod from contacting the test piece.

[0020] Optionally: A plurality of elastic pieces are rotatably connected to the support plate, and the lower ends of the elastic pieces can abut against the upper end surface of the test piece.

[0021] By adopting the above technical solution, the upper end of the test piece is abutted by the elastic pieces, thereby limiting the position of the test piece by relying on the frictional force.

[0022] Optionally: The driving assembly includes a turntable rotatably connected to the base, a driving member for driving the turntable to rotate, and a driving rod rotatably connected to the turntable. The rotation axes of the driving rod and the turntable deviate from the rotation axis of the turntable itself, and the end of the driving rod away from the turntable is hinged to the support plate.

[0023] By adopting the above technical solution, the driving member drives the turntable to rotate, and the driving rod transmits the force to the support plate to drive the support plate to reciprocate.

[0024] In summary, the present application includes the following beneficial technical effects:

[0025] The rubber is connected to the connecting plate through the connecting pin, and then the connecting plate is adsorbed to the magnetic member to connect the connecting plate to the support rod. When replacing the rubber, only need to pull the rubber off the connecting pin to replace the new rubber, and after the replacement is completed, the connecting plate and the magnetic member are attracted to complete.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following further describes the present application in detail with reference to the accompanying drawings.

[0030] A rubber friction paint detection device disclosed in the present application, as Figure 1As shown in the figure, it includes a base 1, a pallet 11 slidably arranged on the base 1, a driving assembly 2 for driving the pallet 11 to reciprocate, a support rod 12 vertically slidable on the base 1, and a connecting assembly 3 for connecting the rubber. The pallet 11 horizontally slides on the upper end surface of the base 1. The driving assembly 2 includes a turntable 21 rotatably connected to the base 1, a driving member 22 for driving the turntable 21 to rotate, and a driving rod 23 rotatably connected to the turntable 21. One end of the driving rod 23 is rotatably connected to the end surface of the turntable 21. The rotation axis of the driving rod 23 and the turntable 21 deviates from the rotation axis of the turntable 21 itself. The other end of the driving rod 23 is hinged to the pallet 11. The driving member 22 is a motor in this embodiment. The motor is installed on the base 1, and the output shaft of the motor is connected to the turntable 21, so as to drive the turntable 21 to rotate, and further drive the pallet 11 to reciprocate. A plurality of elastic pieces 111 are rotatably connected to the pallet 11. The elastic pieces 111 are divided into two columns and arranged along the length direction of the pallet 11. The two columns of elastic pieces 111 are respectively close to the two side walls of the pallet 11 parallel to its moving direction. The lower end of the elastic piece 111 can abut against the upper end of the test piece, so as to limit the position of the test piece on the pallet 11.

[0031] An adjusting assembly 4 for driving the whole support rod 12 to move vertically is arranged on the base 1. The adjusting assembly 4 includes an adjusting seat 41 vertically slidable on the base 1, a lead screw 42 rotatably connected to the base 1, and a hand wheel 43 for driving the lead screw 42 to rotate. The lead screw 42 vertically penetrates through the adjusting seat 41 and is in threaded cooperation with the adjusting seat 41. Two guide rods 44 are vertically installed on the base 1. Both guide rods 44 penetrate through the adjusting seat 41 and the adjusting seat 41 slides along the guide rods 44. The guide rods 44 are arranged on both sides of the lead screw 42. The hand wheel 43 is installed on the upper end of the lead screw 42, so as to drive the lead screw 42 to rotate through the hand wheel 43, and the lead screw 42 drives the adjusting seat 41 to move vertically.

[0032] Three horizontally arranged mounting seats 45 are arranged on the side wall of the adjusting seat 41 close to the pallet 11. The support rod 12 penetrates through the mounting seats 45 and can move vertically along the mounting seats 45. A positioning block 121 is coaxially fixed to the upper end of the support rod 12. There is a gap between the upper end of the positioning block 121 and the upper end of the support rod 12. The distance between the positioning block 121 and the upper end of the support rod 12 is less than the distance between the positioning block 121 and the lower end of the support rod 12, so that the support rod 12 can be pulled out upward and inserted into the mounting seat 45 in an inverted manner, and the positioning block 121 abuts against the mounting seat 45.

[0033] As Figure 2As shown, the connecting component 3 is respectively arranged below the support rod 12. The connecting component 3 includes a connecting sleeve 31 coaxially installed at the lower end of the support rod 12, a magnetic member 32 fixed in the connecting sleeve 31, a connecting plate 33 magnetically attracted to the lower end of the magnetic member 32, and a connecting pin 34 connected to the connecting plate 33. The connecting sleeve 31 is provided with a lower opening. In this embodiment, the magnetic member 32 is selected as a magnet, and the magnet is installed at a position in the inner cavity of the connecting sleeve 31 far from the opening. The connecting plate 33 is disc-shaped, and the connecting plate 33 can be adsorbed to the lower end of the magnetic member 32, and the side wall of the connecting plate 33 can abut against the inner wall of the connecting sleeve 31.

[0034] The connecting pin 34 penetrates through the connecting plate 33, and the connecting pin 34 can slide along the connecting plate 33 and disconnect from the connecting plate 33. A retaining block 35 is coaxially fixed at a position of the connecting pin 34 away from its tip. The thickness of the retaining block 35 is less than the thickness of the connecting plate 33, and the retaining block 35 is made of copper, so that it will not be directly attracted by the magnetic member 32. A receiving groove 331 is provided on the end face of the connecting plate 33 close to the magnetic member 32. The retaining block 35 can be embedded in the receiving groove 331, and the thickness of the retaining block 35 is less than the depth of the receiving groove 331. When connecting it to the rubber, first abut the rubber against the connecting plate 33, then insert the connecting pin 34, and then place the whole in the connecting sleeve 31 so that the connecting plate 33 is adsorbed to the magnetic member 32.

[0035] Since the relative position between the connecting plate 33 and the rubber needs to be limited when abutting the rubber against the connecting plate 33, a connecting ring 36 is coaxially fixed on the end face of the connecting plate 33 away from the magnetic member 32. The outer diameter of the connecting ring 36 is equal to the diameter of the connecting plate 33. The rubber can be directly placed in the connecting ring 36, so that the position of the rubber relative to the connecting plate 33 can be directly limited by the connecting ring 36, and the axis of the rubber can be directly coincident with the axis of the connecting plate 33, making the installation of the rubber more convenient.

[0036] Since the rubber will be worn after use and the connecting plate 33 needs to be removed from the connecting sleeve 31, a butting ring 37 is coaxially fixed at a position on the outer wall of the connecting ring 36 away from the support rod 12. The distance between the upper end of the butting ring 37 and the upper end face of the connecting plate 33 is greater than the distance between the lower end of the connecting sleeve 31 and the lower end of the magnetic member 32. The diameter of the butting ring 37 is greater than the outer diameter of the connecting sleeve 31. Thus, when the connecting plate 33 needs to be removed from the connecting sleeve 31, a downward force can be directly applied to the butting ring 37 to remove the connecting plate 33 from the connecting sleeve 31.

[0037] The implementation principle of this embodiment is as follows: After the rubber eraser wears out, lift the support rod 12 upward by a certain distance. Then, pinch the abutting ring 37 to pull out the connecting plate 33 from the connecting sleeve 31. Return the support rod 12 to its original position. Pinch the connecting ring 36 to pull the rubber eraser off the connecting pin 34. After that, insert the rubber eraser into the connecting ring 36, and then push the connecting pin 34 into the connecting ring 36 so that the connecting pin 34 inserts into the rubber eraser. Then, lift the support rod 12 upward again. When inserting the connecting plate 33 into the connecting sleeve 31, the connecting plate 33 is adsorbed on the magnetic member 32.

[0038] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
