Description

Technical Field

[0001] This utility model relates to the field of aluminum guide roller processing equipment, and specifically to an aluminum guide roller processing tooling. Background Technology

[0002] Aluminum alloy guide rollers (abbreviated as aluminum guide rollers) are wheel and axle components used in industrial production. They are usually made of aluminum alloy and are widely used in production lines or conveyor systems to assist in conveying and guiding. The production process of aluminum guide rollers involves one or more processing steps such as drilling, grinding, and polishing, thus requiring various fixtures to fix them to the worktable.

[0003] In existing technologies, the fixtures used for polishing aluminum guide rollers are mostly jaw-type fixtures. These require the three gripping arms of the jaws to contact the end face / circumferential surface of the aluminum guide roller, and ultimately, the radial clamping force exerted by the multiple gripping arms on the end of the aluminum guide roller is used to fix it on the worktable. Therefore, using existing fixtures for polishing and grinding aluminum guide rollers easily creates interference zones at the ends, leading to operational difficulties during the polishing and grinding process. This affects the overall uniformity and consistency of the aluminum guide roller's surface quality, and localized problems with the aluminum guide roller can easily affect the controllability, reliability, and stability of the overall transmission effect during use. In actual processing, the end positions of the aluminum guide roller often need to be polished and ground separately, thus limiting processing efficiency. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an aluminum guide roller processing fixture, which helps eliminate the step of separately processing the ends of the aluminum guide roller, thereby improving processing efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an aluminum guide roller processing fixture, including a base, two slides arranged opposite each other on the base, and two clamping blocks that correspond to and match the slides one by one.

[0006] The slide and the base are matched by a track structure extending left and right, allowing the slide to switch between a moving state relative to the base and a fixed state. Two first protruding arms are formed on the slide, arranged opposite each other and extending vertically upwards. A through-hole is formed on each first protruding arm, and a bolt with its axis along the vertical direction is provided, allowing the free end of the bolt to be screwed into the through-hole.

[0007] The clamping block has a pair of opposing arm plates formed on its inner end and a pair of opposing arm plates formed on its outer end. At least one V-shaped groove is formed at the free end of arm plate one. Arm plate two corresponds to the slots on the two first protruding arms, allowing the clamping block to move left and right / translate relative to the slide. Tightening the bolts allows the bolt end face to contact and disengage from the upper end face of arm plate two, thus controllably switching the clamping block between a movable state relative to the slide and a fixed state.

[0008] Optionally, the base is provided with multiple convex rails that are alternately arranged front and back and extend left and right, and the lower part of the slide is provided with a track groove that matches the convex rails, so that the slide can move left and right relative to the base, thereby realizing the adjustment of the left and right distance between the two slides.

[0009] Optionally, the base is provided with a plurality of straight grooves that are alternately arranged front and back and extend to the left and right.

[0010] The slide is provided with multiple locking components, which can be matched with the straight grooves respectively, and the slide can switch between moving relative to the base and remaining fixed.

[0011] Optionally, the locking assembly includes a stud and a nut, with the nut engaging with a threaded portion formed at the end of the stud's shank. The slide has a vertical through-hole that matches the stud, and the stud's shank passes upward through a straight slot and the vertical through-hole, with the threaded portion extending beyond the vertical through-hole before engaging with the nut. The stud's cap is located below the straight slot, and the outer diameter of the cap is larger than the width of the straight slot, allowing a facing surface to be formed between the cap and the lower end of the straight slot.

[0012] Optionally, an elastic washer is fitted onto the stud, and the elastic washer is positioned between the upper end face of the stud cap and the lower end opening of the straight groove, so that the elastic washer can be clamped between the upper end face of the cap and the edge of the lower end opening of the straight groove.

[0013] Optionally, multiple flanges are arranged alternately at the bottom of the slide. The flanges extend vertically downwards, and the lower part of the flanges matches the base via a left-right extending track structure. By setting the flanges, the height of the upper surface of the slide can be significantly raised, thus better accommodating aluminum guide rollers with a wider range of outer diameters.

[0014] Optionally, a rubber pad is fixedly provided on the inner end groove surface of the V-shaped groove, and the rubber pad protrudes relative to the groove surface.

[0015] Optionally, two second protruding arms are formed on the slide block, arranged opposite each other, with the second protruding arms positioned outside the first protruding arm. A through-hole is formed on the second protruding arm.

[0016] The free ends of the second arm plate are connected together by end plates, and two columns are arranged alternately in front and behind on the end plates, with the columns extending outward in the left and right direction and passing through the smooth holes.

[0017] A spring is fitted onto a section of the column extending beyond the smooth end of the hole, and a second nut is positioned at the end. The two ends of the spring contact the end face of the second nut and the side face of the second arm plate, respectively.

[0018] Optionally, a vertically upward extending lever is provided on the end plate.

[0019] Optionally, multiple V-shaped slots are provided on the first arm plate, and the number of V-shaped slots provided on each first arm plate is the same.

[0020] The multiple V-shaped slots on the two arm plates of the left clamping block correspond one-to-one with the multiple V-shaped slots on the two arm plates of the right clamping block, and are distributed in the same straight line direction extending left and right.

[0021] Multiple V-shaped slots on two arm plates on the same clamping block are symmetrical about the center of the front-to-back vertical distance between the two arm plates.

[0022] The beneficial effects of this utility model are: this utility model can overcome the interference problem caused by the fixture at the end of the aluminum guide roller during polishing and other processing processes, and helps to eliminate the step of processing the end of the aluminum guide roller separately, thereby improving processing efficiency.

Detailed Implementation

[0030] The structures, proportions, and sizes shown in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. 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. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0031] like Figures 1 to 6 The aluminum guide roller processing fixture shown includes a base 10, two slides 20 arranged opposite each other on the base 10, and two clamping blocks 30 that correspond to and match the two slides 20 one by one.

[0032] The base 10 is a rectangular plate and can be detachably mounted on a worktable (not shown in the figure) using conventional fixing mechanisms such as bolts and clips, thereby establishing a connection between the machining fixture involved in this application and the worktable. It should be emphasized that the fixing connection method between the base 10 and the worktable, as well as the specific structures provided on both, can be flexibly determined by referring to the specific structural style of the existing worktable surface (such as holes, grooves, protruding ridges, edge plates, etc. provided on the worktable). Since it can be implemented with reference to existing technology and has a weak correlation with the core problem to be overcome in this application, it will not be described in detail.

[0033] The slide block 20 and the base 10 are matched by a track structure extending left and right, allowing the slide block 20 to switch between a state of moving left and right relative to the base 10 and a state of remaining fixed. In this way, the two slide blocks 20 can move closer and further apart from each other and maintain a suitable left and right distance to accommodate the need to fix aluminum guide rollers 40 of different lengths.

[0034] like Figures 1 to 4 As shown, specifically, the base 10 is provided with two alternating front-to-back convex rails 11, both extending left and right. The lower part of the slide 20 is provided with a track groove that matches the convex rails 11. The track groove can be located below two edge plates 21 located at the lower part of the slide 20. The length of the two edge plates 21 located at the lower part of the slide 20 is along the left-right direction, and a front-to-back gap is formed between the two edge plates 21. The base 10 is provided with two alternating front-to-back straight grooves 12, both extending left and right. The slide 20 is provided with four locking components 24, such that every two locking components 24 can correspond to and match one straight groove 12 respectively (and the two locking components 24 arranged on one straight groove 12 are arranged left and right alternately), and (with the help of the locking components 24) the slide 20 can switch between a state of left-to-right movement relative to the base 10 and a state of being fixed. The locking assembly 24 may include a stud 241 and a nut 243, and the nut 243 may be matched with a threaded portion 242 formed at the end of the rod of the stud 241.

[0035] The slide block 20 has a vertical through hole that matches the stud 241. The stud 241's shaft passes upward through the straight groove 12 and the vertical through hole, and the threaded portion 242 extends (upward) out of the vertical through hole and matches the nut 243. The outer diameter of the stud 241's cap is larger than the width of the straight groove 12. Thus, tightening the nut 243 pulls the stud 241 upward, causing its upper cap to press against the lower edge of the straight groove 12, achieving the purpose of keeping the slide block 20 fixed relative to the base 10 (state adjustment). Tightening the nut 243 in the opposite direction causes the stud 241 to fall downward under gravity, disengaging its upper cap from the lower edge of the straight groove 12, achieving the purpose of moving the slide block 20 left and right relative to the base 10 (state adjustment). To improve the contact between the stud 241 and the lower edge of the groove 11, and to optimize the stability and reliability of the locking assembly 24 in maintaining a fixed connection between the slide 20 and the base 10, an elastic washer 244 is fitted onto the stud 241. When the nut 243 is tightened and the stud 241 is pulled upwards, causing the upper surface of its cap to press against the lower edge of the groove 12, the elastic washer 244 is compressed and undergoes elastic deformation. The elastic washer 244 can be made of rubber or polyester material.

[0036] Two first protruding arms 22 are formed on the slide block 20, arranged opposite each other, with the first protruding arms 22 extending vertically upward and having a large extension width in the front-back direction. A through-hole 221 is formed on the wall of the first protruding arm 22, and a bolt 222 with its axis along the vertical direction is provided. The through-hole 221 has a flat, hole-like structure and a large front-back width. The bolt 222 is located at the top of the first protruding arm 22, and the free end of the bolt 222 can be screwed into the through-hole 221. For ease of assembly (clamping block 30), the first protruding arm 22 can include a protruding arm body and a cover provided on the protruding arm body, and the cover and the protruding arm body can be fixedly connected together by bolts or screws. The slot 221 is provided on the top surface of the protruding arm body, and the threaded through hole corresponding to the screw of the bolt 222 is provided on the cover. Tightening the bolt 222 can make its free end move vertically, and the length of its extension into the slot 221 can be controlled.

[0037] On the clamping block 30, a pair of front-to-back opposing arm plates 31 are formed on the inner end side (i.e., the opposite end sides between the clamping blocks 30), and a pair of front-to-back opposing arm plates 32 are formed on the outer end side. The width of the first arm plate 31 and the width of the second arm plate 32 are both in the front-to-back direction, and the thickness is a parameter in the vertical direction.

[0038] At least one V-shaped groove 311 is formed at the free end of the arm plate 31. A rubber pad 312 can be fixedly provided on the inner end groove surface of the V-shaped groove 311, and the rubber pad 312 protrudes relative to the groove surface, see [reference]. Figure 1 It should be noted that the number of V-shaped slots 311 provided on each of the arm plates 31 is the same; the V-shaped slots 311 provided on two arm plates 31 arranged opposite each other can correspond one-to-one, see [reference]. Figure 1 The V-shaped slots 311 provided on the two opposing arm plates 31 are symmetrical about the midpoint of the vertical distance between the two arm plates 31 in the front-rear direction. See [reference needed]. Figure 2 As shown, the three sets of V-shaped slots 311 indicated by the dotted lines enable two symmetrical V-shaped slots 311 (each set on one of the two arm plates 31) to correspond and match with the front and rear side walls of the port of the aluminum guide roller 40 (that is, the port wall of the aluminum guide roller 40 can be inserted into the two V-shaped slots 311 and can be fixed under the action of left and right pushing pressure).

[0039] By providing a rubber pad 312 at the inner end of the V-groove 311, damage to the end wall of the aluminum guide roller 40 can be prevented during clamping. Furthermore, the contact area between the arm plate 31 and the end of the aluminum guide roller 40 can be increased, improving the stability and reliability of the pressing process and preventing slippage or shaking. The rubber pad 312 can be made of rubber or polyethylene.

[0040] The arm plate 32 corresponds one-to-one with the slots 221 on the two first protruding arms 22 (on the same slide block 20), so that the clamping block 30 can move left and right / translate relative to the slide block 20. Tightening the bolt 222 can controllably switch the clamping block 30 between a state that can move relative to the slide block 20 and a state that remains fixed. The left and right distance between the two opposing V-shaped slots 311 can be adjusted so that the V-shaped slots 311 can fully match the port of the aluminum guide roller 40, thereby fixing and clamping the end of the aluminum guide roller 40.

[0041] In the above scheme, two arm plates 31 on the left side are used to fix the left end of the aluminum guide roller 40, and two arm plates 31 on the right side are used to fix the right end of the aluminum guide roller 40, thereby fixing the left and right ends of the aluminum guide roller 40 respectively, preventing it from rotating or moving left and right. The arm plate 31 is a plate structure, and its thickness is significantly smaller than the outer diameter of the aluminum guide roller 40. When clamping the end of the aluminum guide roller 40, it will not form significant obstruction, allowing the end of the aluminum guide roller 40 to be in a better open state. This facilitates polishing and grinding processing (processing feed direction along the axial direction) while the clamp is fixed, without the need for separate local processing. At least by loosening the fit between the arm plate 31 on one end and the aluminum guide roller 40, and twisting the aluminum guide roller 40 to rotate, the upward and forward facing wall / outer peripheral surface area of ​​the aluminum guide roller 40 can be adjusted, making it easy to process the entire peripheral surface. Therefore, this utility model can overcome the interference problem caused by the fixture at the end of the aluminum guide roller 40 during polishing and other processing processes, and helps to eliminate the step of processing the end of the aluminum guide roller 40 separately, thereby improving processing efficiency.

[0042] like Figures 1 to 2 , Figures 5 to 6 As shown, two second protruding arms 23 are formed on the slide block 20, arranged opposite each other, with the second protruding arms 23 positioned outside the first protruding arm 22. A smooth, through-hole 231 is formed on the second protruding arm 23. The smooth, through-hole 231 can be a cylindrical hole or a prism hole.

[0043] The free ends of the second arm plate 32 are connected together via an end plate 33. Two studs 34 are arranged alternately on the end plate 33, extending outwards in the left-right direction and passing through the smooth hole 231. The outer diameter of the main body of the stud 34 is the same as the inner diameter of the smooth hole 231, guiding the clamping block 30 to move relative to the slide block 20 in the left-right direction. This, combined with the guiding movement of the second arm plate 32 and the slot 221, improves the stability and straightness of the left-right movement of the clamping block 30. A section of the outer circumferential surface of the stud 34 corresponds to and matches the smooth hole 231, establishing a surface contact matching relationship between them.

[0044] A spring 35 is fitted onto a section of the column 34 extending to the outer end of the smooth hole 231, and a nut 341 is disposed at the end of the column 34. The two ends of the spring 35 contact the end face of the nut 341 and the outer side of the arm plate 32, respectively. The free end of the column 34 has an external thread section, and the nut 341 is disposed on this thread section, allowing the left-right position of the nut 341 on the column 34 to be adjusted. This allows the initial compression state of the spring 35 to be set, enabling the spring 35 to apply an outward elastic thrust to the clamping block 30. After the bolt 222 releases pressure on the arm plate 32, the clamping block 30 automatically moves outward (to the left or right), automatically increasing the left-right distance between the two clamping blocks 30 and improving operational convenience.

[0045] For ease of assembly (clamping block 30 or column rod 34), the second protruding arm 23 can include a protruding arm body and a cover disposed on the protruding arm body, and the cover and the protruding arm body are fixedly connected together by bolts or screws. One half of the smooth hole 231 is disposed on the top surface of the protruding arm body, and the other half is disposed on the cover. After the aforementioned cover is fixed to the aforementioned protruding arm body, it can be snapped together to form the smooth hole 231.

[0046] To increase ease of operation, a vertically extending lever 331 is provided on the end plate 33 at a central position in the front-to-back direction.

[0047] 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.
