Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping fixture technology, specifically to a rotating clamping fixture for a surface cleaning device used in aluminum guide roller processing. Background Technology
[0002] Aluminum guide rollers are industrial roller components made of high-quality aluminum alloy materials, and are widely used in roll material processing equipment in industries such as printing, packaging, plastics, and electronic batteries.
[0003] During the turning process, aluminum guide rollers easily accumulate impurities, debris, and other contaminants on their outer surface. Therefore, cleaning is necessary after turning. In conventional operations, the aluminum guide rollers are typically placed in a cleaning tank, and the cleaning fluid is agitated to wash away the impurities and debris. However, this method is problematic because the aluminum guide rollers are often scattered in the cleaning tank, or multiple rollers are gathered together using ropes or a collection frame before being submerged. This can lead to excessive collisions between the rollers, or some rollers may not be thoroughly cleaned, requiring rework and thus reducing cleaning efficiency. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a rotating clamping fixture for a surface cleaning device used in aluminum guide roller processing. This fixture can simultaneously fix multiple aluminum guide rollers to prevent them from colliding with each other, and can conveniently complete the fixing and disassembly operations of the aluminum guide rollers by pulling and rotating the movable cross arm.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a rotating clamping fixture for a surface cleaning device for aluminum guide roller processing, including a U-shaped frame, a movable cross arm, and multiple cylindrical bodies respectively fixed on the cross arm of the U-shaped frame and the movable cross arm.
[0006] A stud is formed at one end of one longitudinal arm of the U-shaped frame, and a spring is fitted onto the stud. A threaded countersunk hole is formed at the other end of the longitudinal arm of the U-shaped frame.
[0007] Multi-stage through holes corresponding to studs and smooth through holes corresponding to countersunk threads are formed on both ends of the movable cross arm. A nut is fitted onto the stud after it passes through the multi-stage through holes. One end of a spring extends into the multi-stage through holes, allowing the movable cross arm to rotate relative to the U-shaped frame around the stud. A bolt is fitted onto the smooth through hole, and the end of the bolt's thread can be screwed into the countersunk thread. A section of the bolt near its root is formed as a smooth cylindrical section, which is matched to the smooth through hole.
[0008] The outer circumference of the cylindrical body is tapered at the free end, with the smaller diameter end being the free end.
[0009] Optionally, multiple multi-tiered convex pillars are formed on the upper end face of the cross arm, with the outer diameter of the base section of each multi-tiered convex pillar being larger than the outer diameter of the free end section. Multiple countersunk holes are formed on the lower end face of the cross arm, which are vertically aligned with the multi-tiered convex pillars. The inner diameter at the countersunk hole port is smaller than the outer diameter of the base section but not smaller than the outer diameter of the free end section, allowing the free end section to be inserted into the countersunk hole.
[0010] Multiple trapezoidal protrusions extending longitudinally are formed on the upper end face of the movable cross arm. Multiple trapezoidal grooves are formed on the lower end face of the movable cross arm, which are vertically aligned with the trapezoidal protrusions and extend longitudinally, allowing each trapezoidal protrusion to be inserted into its corresponding groove.
[0011] Optionally, an elastic sleeve is fitted at the root of the free end segment.
[0012] Optionally, elastic protrusions are fixedly arranged on the upper part of the inclined surface of the trapezoidal protrusion.
[0013] Optionally, the vertical height of the horizontal arm is not less than the vertical height of the longitudinal arm; the vertical height of the horizontal arm is consistent with the vertical height of the movable horizontal arm and is greater than the outer diameter of the aluminum guide roller.
[0014] Optionally, an elastic rubber ring is fixedly embedded in the middle of the outer peripheral surface of the cylindrical body. The outer peripheral surface of the elastic rubber ring is formed as an outwardly protruding arch, and the arch extends axially.
[0015] Optionally, an annular member is fixedly provided on the outer circumferential surface of the bolt near its free end. The outer diameter of the annular member is larger than the outer diameter of the bolt. A countersunk portion is formed at the outer end of the threaded countersunk hole, and the inner diameter of the countersunk portion is larger than the outer diameter of the annular member.
[0016] Optionally, the annular component is a rubber ring and is embedded and fixed on the threaded rod of the bolt component.
[0017] The beneficial effects of this utility model are: it can fix multiple aluminum guide rollers at the same time to prevent them from colliding with each other, and the fixing and disassembly of the aluminum guide rollers can be easily completed by pulling and rotating the movable cross arm.

They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, terms such as "upper," "lower," "front," "rear," and "middle" used in this specification are merely for clarity and not intended to limit the scope of this invention.

[0026] like Figures 1 to 6 The rotating clamping fixture for a surface cleaning device in aluminum guide roller processing (also known as a clamping fixture for a surface cleaning device in aluminum guide roller processing) shown includes a U-shaped frame 10, a movable cross arm 20, and a plurality of cylindrical bodies 30 respectively fixedly mounted on the cross arm 11 of the U-shaped frame 10 and the movable cross arm 20. That is, the U-shaped frame 10 and the movable cross arm 20 can be joined to form a rectangular or square frame, and the plurality of cylindrical bodies 30 mounted on the cross arm 11 and the plurality of cylindrical bodies 30 mounted on the movable cross arm 20 are positioned left-right opposite each other. The shaft holes 31 of the cylindrical bodies 30 on the cross arm 11 and the shaft holes 31 of the cylindrical bodies 30 on the movable cross arm 20 can each coincide (including approximately coincident cases) in the left-right direction. In use, the two ends of the aluminum guide roller 100 can be respectively inserted into the cylindrical body 30 on the cross arm 11 and the cylindrical body 30 on the movable cross arm 20, and thus fixed on the rotating clamping fixture.
[0027] The cylindrical body 30 and the cross arm 11, as well as the cylindrical body 30 and the movable cross arm 20, can all be integrally formed structures, or they can all be fixed connection structures (including detachable fixed connection forms).
[0028] A stud 121 is formed at the end of one longitudinal arm 12 of the U-shaped frame 10, and a spring 122 is fitted onto the stud 121. The axial direction of the stud 121 is along the extending direction of the longitudinal arm 121. A threaded countersunk hole 124 is formed at the end of the other longitudinal arm 12 of the U-shaped frame 10. The axial direction of the threaded countersunk hole 124 is along the extending direction of the longitudinal arm 121.
[0029] Multi-stage through holes 21 corresponding to the studs 121 and smooth through holes 22 corresponding to the countersunk holes 124 are formed on both ends of the movable cross arm 20.
[0030] The stud 121 passes through the multi-stage through hole 21 and is fitted with a nut 123. One end of the spring 122 extends into the multi-stage through hole 21, and the other end contacts the end face of the longitudinal arm 12. Tightening the nut 123 (acting simultaneously with the spring 122) pushes one end of the movable cross arm 20 towards and away from the end of the longitudinal arm 12. In this way, the movable cross arm 20 can rotate relative to the U-shaped frame 10 around the stud 121, while keeping the open end of the U-shaped frame 10 in an open and closed state, so as to adaptably install and remove / uninstall the aluminum guide roller 100 on the fixture.
[0031] A bolt member 221 is disposed on the smooth through hole 22, and the screw end of the bolt member 221 can be screwed into the threaded countersunk hole 124. A section of the screw near the root of the bolt member 221 is formed into a smooth column section, and the smooth column section can be matched with the smooth through hole 22; the outer diameter of the smooth column section can be consistent with the inner diameter of the smooth through hole 22.
[0032] The outer peripheral surface of the cylindrical body 30 is tapered at the free end, with the smaller diameter end being the free end.
[0033] In this way, the stud 121, the spring 122, and the nut 123 can fix one end of the movable cross arm 20 to the end of one longitudinal arm 12 of the U-shaped frame 10, and enable the two to rotate relative to each other, and maintain a (left-right) distance between the ends of the movable cross arm 20 and the longitudinal arm 12; at the same time, the bolt 221 can detachably fix the other end of the movable cross arm 20 to another longitudinal arm 12 of the U-shaped frame 10; finally, it can achieve the purpose of switching the open end state of the U-shaped frame 10 in a coordinated manner, which facilitates the fixing, installation, and disassembly of the aluminum guide roller 100; the movable cross arm 20 can also slide relative to the U-shaped frame 10 in the left-right direction under the constraint (guidance) of the stud 121 and the bolt 221, so as to quickly complete the fixing of both ends of the aluminum guide roller 100. Figure 1 The diagram shows the state when the right end of the aluminum guide roller 100 is inserted into the cylindrical body 30 on the horizontal arm 11. Then, by fixing the other end of the movable horizontal arm 20 to the vertical arm 12 using the bolt 221, the movable horizontal arm 20 can be pushed to the right, causing the cylindrical body 30 on the movable horizontal arm 20 to engage with the other end of the aluminum guide roller 100. The shaft hole 31 on the cylindrical body 30 can communicate with the shaft cavity of the aluminum guide roller 100.
[0034] To enable the multiple aluminum guide roller surface cleaning devices for rotating clamping fixtures (hereinafter referred to as fixtures) to be stacked vertically in multiple layers and kept fixed, a plurality of multi-stage convex pillars 111 are formed on the upper end face of the horizontal arm 11, and the outer diameter of the base segment 1111 (the segment near the root) of the multi-stage convex pillar 111 is larger than the outer diameter of the free end segment 1112. A plurality of countersunk holes 112 are formed on the lower end face of the horizontal arm 11, which are vertically aligned with the multi-stage convex pillars 111. The inner diameter of the countersunk hole 112 port is smaller than the outer diameter of the base segment 1111 and larger than the outer diameter of the free end segment 1112. At the same time, the inner diameter of the countersunk hole 112 body is consistent with the outer diameter of the free end segment 1112, so that the free end segment 1112 (on one fixture) can be inserted into the countersunk hole 112 (on another fixture), thereby establishing a stable insertion connection between the two fixtures. Meanwhile, multiple trapezoidal protrusions 23 extending longitudinally are formed on the upper end face of the movable cross arm 20. Multiple trapezoidal grooves 24 are formed on the lower end face of the movable cross arm 20, which are vertically aligned with and longitudinally penetrate the trapezoidal protrusions 23, allowing the trapezoidal protrusions 23 (on one tooling) to be inserted into the trapezoidal grooves 24 (on another tooling). The cross arms 11 of the multiple toolings are connected via a structure of column holes (multi-stage convex columns 111 and countersunk holes 112), while the movable cross arm 20 on the other side is matched by the structural connection of the trapezoidal protrusions 23 and the trapezoidal grooves 24. This reduces processing and assembly difficulty, quickly completing the connection between columns and holes and between strips and grooves. While ensuring the stability of the stacked tooling, it also facilitates operation and processing.
[0035] In order to enable the base segment 1111 to play a good supporting role and to form good contact with the lower end face of the cross arm 11, an elastic sleeve 113 is fitted at the root of the free end segment 1112, and the elastic sleeve 113 has a certain axial extension length.
[0036] Elastic protrusions are fixedly arranged on the upper part of the inclined surface of the trapezoidal protrusion 23. In this way, after the trapezoidal protrusion 23 is inserted into the trapezoidal groove 24, the deformation of the elastic protrusions can make the (outer) inclined surface of the trapezoidal protrusion 23 fully contact the (inner) inclined surface of the trapezoidal groove 24, forming a stable insertion support.
[0037] like Figures 1 to 5 As shown, the length of the trapezoidal protrusion 23 and the length of the trapezoidal groove 24 are both along the left-right direction (longitudinal direction), and the cross-section of the trapezoidal protrusion 23 (in the front-back direction, see the side view) is... Figure 6 (The same applies below) It is trapezoidal, and the cross-section of the trapezoidal groove 24 is also trapezoidal.
[0038] The vertical height of the horizontal arm 11 is greater than the vertical height of the vertical arm 12; at the same time, the vertical height of the horizontal arm 11 is the same as the vertical height of the movable horizontal arm 20, and is greater than the outer diameter of the aluminum guide roller 100. In this way, after the aluminum guide roller 100 is fixed on the fixture, it can be supported inside the fixture without contacting the inner wall of the cleaning tank.
[0039] An elastic rubber ring 32 is fixedly embedded in the middle of the outer peripheral surface of the cylindrical body 30. The outer peripheral surface of the elastic rubber ring 32 is formed as an outwardly protruding arch, and the arch extends axially. When the aluminum guide roller 100 is inserted into the cylindrical body 30, the inner wall of the port of the aluminum guide roller 100 can compress the elastic rubber ring 32 to deform, so that the elastic rubber ring 32 can stably support the aluminum guide roller 100.
[0040] An annular member 2211 is fixedly provided on the outer peripheral surface of the bolt 221 near its free end. The outer diameter of the annular member 2211 is larger than the outer diameter of the bolt 221. Correspondingly, a countersunk portion 1241 is formed at the outer port of the threaded countersunk hole 124, and the inner diameter of the countersunk portion 1241 is larger than the outer diameter of the annular member 2211. When the bolt end of the bolt 221 is fully screwed into the threaded countersunk hole 124, the annular member 2211 can be correspondingly inserted into the countersunk portion 1241. The annular member 2211 prevents the bolt 221 from falling off the movable cross arm 20. The annular member 2211 is a rubber ring and is embedded and fixed on the bolt 221.
[0041] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit it. Many aspects of this utility model can be improved without departing from the overall concept. Those skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
