Description

Technical Field

[0001] This utility model relates to the field of fresh air equipment processing technology, and in particular to a movable circular filter assembly fixture. Background Technology

[0002] In the assembly process of circular filters in a fresh air system, the core step is to precisely bond and fix the filter material to the inside of a rigid annular rim. This annular rim provides structural support for the filter and ensures its airtightness. During assembly, the annular rim needs to be stably clamped and fixed first, and then adhesive is evenly applied to its inner upper surface. The cut circular filter material is then placed flat and accurately on the adhesive surface, and pressure is applied to complete the bonding. This process requires extremely high positioning stability of the annular rim. Any deviation or loosening may lead to improper bonding or poor sealing of the filter, affecting the filtration performance and structural reliability of the final product.

[0003] Traditional assembly fixtures have significant limitations when clamping annular edging. Their clamping mechanisms are usually designed with fixed dimensions and can only accommodate annular edging of a specific diameter. When different sizes of circular filter screens need to be assembled on the production line, operators must frequently change the entire fixture or its main clamping components. This not only increases equipment costs and changeover time and reduces production efficiency, but more importantly, the size mismatch causes the clamping mechanism to be unable to tightly fit the inner edge of annular edging of different diameters. Insufficient or uneven clamping force can easily cause workpiece displacement during glue application and filter screen placement, directly affecting assembly accuracy and product yield. Utility Model Content

[0004] The purpose of this utility model is to provide a movable circular filter assembly fixture, which solves the problem that traditional circular filter assembly fixtures cannot be adapted to circular filters of different sizes and specifications.

[0005] To achieve the above objectives, this utility model provides a movable circular filter assembly fixture, including a housing. A support platform is fixedly mounted on the upper end of the housing, and a base is fixedly mounted on the lower end of the housing. A control button is fixedly mounted on the front end of the housing. A heat dissipation hole is provided on the right end of the housing. A switch is fixedly mounted below the heat dissipation hole, and a power interface is fixedly mounted behind the switch. A clamping assembly is provided on the upper end of the housing. The housing provides overall support and component protection. The support platform supports the clamping assembly and the workpiece above. The base ensures that the fixture is placed stably. The control button allows the operator to start and stop the equipment. The heat dissipation hole promotes the dissipation of internal heat. The switch controls the on / off state of the circuit system. The power interface is connected to an external power input.

[0006] The clamping assembly includes an electric push rod, which is fixedly installed inside the housing. A push rod is fixedly installed at the upper end of the electric push rod. The clamping assembly performs the core clamping function. The electric push rod provides linear extension and retraction driving force, and the push rod transmits the linear motion of the electric push rod.

[0007] The support platform has a movably mounted bracket on its upper side. The bracket is cross-shaped. The push rod is connected to the bracket via a fixing member. The bracket can switch and distribute linear movement to four directions. The fixing member reliably connects the push rod and the bracket.

[0008] The bracket has four sliding grooves at its upper end, and each sliding groove has a movably mounted support fan plate at its upper end. The sliding grooves guide the support fan plate to move radially, and the support fan plate carries the annular edging and performs radial movement.

[0009] The upper end of the supporting fan plate is fixedly provided with a clamping block. The clamping block is fan-shaped, and the chord length of the fan shape of the clamping block is smaller than that of the supporting fan plate. A buffer pad is fixedly provided on the outer side of the clamping block. The clamping block directly contacts and clamps the inner edge of the annular edging. The clamping block is fan-shaped to match the shape of the workpiece. The chord length of the fan shape of the clamping block is smaller than that of the supporting fan plate to ensure the clamping position. The buffer pad provides flexible contact to protect the surface of the workpiece.

[0010] The lower end of the supporting fan plate is fixedly provided with a movable rod, which passes through a sliding groove and connects the supporting fan plate with the lower linkage mechanism. The movable rod passes through the sliding groove and is constrained by it to move radially.

[0011] The lower end of the movable rod is fixedly provided with a connecting rod, and the end of the connecting rod away from the movable rod is fixed to the support platform through a rotating shaft. The connecting rod converts the vertical movement of the bracket into the radial movement of the movable rod, and the rotating shaft provides a fulcrum for the connecting rod to be fixed to the support platform.

[0012] It achieves efficient and precise clamping and positioning. The electric push rod drives the push rod to move, which in turn drives the cross bracket to rise and fall through the fixing parts. The bracket's rise and fall are linked to the movement of the connecting rod, which pulls the movable rod to slide within the sliding groove. The movable rod drives the support fan blades to move radially and synchronously. The fan-shaped clamping blocks fixed on the support fan blades, together with the buffer pads, ensure that the four clamping blocks can simultaneously and accurately contract centrifugally or expand centrifugally, firmly clamping the inner edge of the annular edging at the bottom of the circular filter screen. This ensures accurate positioning without deviation, laying the foundation for subsequent precise glue application and filter screen bonding. The operator only needs to start the electric push rod with the control button to complete the synchronous contraction of the clamping blocks with one click. The entire process of placing the workpiece and simultaneously expanding to clamp it eliminates the need for manual adjustment of each fixture, greatly simplifying the operation, reducing labor intensity, and improving assembly efficiency. The power interface and switch facilitate power connection and management. The buffer pads on the outside of the clamping blocks provide flexible contact when clamping the annular edge, effectively preventing surface indentations or scratches caused by rigid clamping and protecting the workpiece's integrity. The housing protects the internal mechanisms, and the ventilation holes promote airflow and heat dissipation, ensuring stable operation of components such as the electric push rod over extended periods and extending the fixture's lifespan. The design of moving parts such as the shaft and connecting rod ensures reliable operation. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Please see Figures 1-4 A movable circular filter assembly fixture includes a housing 1, a support platform 2 fixedly mounted on the upper end of the housing 1, a base 3 fixedly mounted on the lower end of the housing 1, a control button 4 fixedly mounted on the front end of the housing 1, a heat dissipation hole 5 opened on the right end of the housing 1, a switch 6 fixedly mounted on the lower side of the heat dissipation hole 5, a power interface 7 fixedly mounted on the rear side of the switch 6, a clamping assembly mounted on the upper end of the housing 1, the housing 1 providing a mounting base and protection for all components, the support platform 2 supporting the clamping assembly and the workpiece, the base 3 ensuring the entire fixture is placed stably and preventing movement, the control button 4 receiving operator commands to control the movement of an electric push rod 8, the heat dissipation hole 5 promoting air circulation to dissipate the heat generated by the internal components, the switch 6 controlling the opening and closing of the entire fixture's power circuit, and the power interface 7 connecting to an external power source to provide working power to the electric push rod 8.

[0021] The clamping assembly includes an electric push rod 8, which is fixedly installed inside the housing 1. A push rod 9 is fixedly installed at the upper end of the electric push rod 8. A bracket 10 is movably installed on the upper side of the support platform 2. The bracket 10 is cross-shaped. The upper part of the push rod 9 is connected to the bracket 10 through a fixing member 11. Four sliding grooves 12 are opened at the upper end of the bracket 10. Supporting fan blades 13 are movably installed at the upper end of each sliding groove 12. The clamping assembly performs the core clamping function. The electric push rod 8 serves as a power source to generate linear extension and retraction motion. The push rod 9 is fixedly connected to the output end of the electric push rod 8 to transmit its linear extension and retraction motion. The bracket 10 is connected to the push rod 9 through the fixing member 11 to receive its vertical motion and distribute the motion to four directions. The fixing member 11 firmly connects the push rod 9 and the bracket 10 to ensure reliable power transmission. The sliding grooves 12 are opened at the upper end of the bracket 10 to provide a precise guide path for the radial movement of the supporting fan blades 13. The supporting fan blades 13 are movably installed at the upper end of the sliding grooves 12 to bear the annular edging and perform radial movement to complete clamping or release.

[0022] A clamping block 14 is fixedly installed at the upper end of the supporting fan blade 13. The clamping block 14 is fan-shaped, and the chord length of the fan shape of the clamping block 14 is less than that of the supporting fan blade 13. A buffer pad 15 is fixedly installed on the outer side of the clamping block 14. A movable rod 16 is fixedly installed at the lower end of the supporting fan blade 13. The movable rod 16 passes through the sliding groove 12. A connecting rod 17 is fixedly installed at the lower end of the movable rod 16. The end of the connecting rod 17 away from the movable rod 16 is fixed to the support platform 2 through a rotating shaft 18. The clamping block 14 is fixed to the upper end of the supporting fan blade 13, directly contacting and clamping the inner edge of the annular edging. The clamping block 14 has a fan-shaped structure that matches the arc shape of the annular edging. The chord length of the fan shape of the clamping block 14 is less than that of the supporting fan blade 13. The clamping force, less than that of the supporting fan 13, is applied to a specific position of the annular edge. The buffer pad 15 is fixed to the outside of the clamping block 14 and generates elastic deformation during clamping to provide flexible contact and protect the surface of the annular edge from damage. The movable rod 16 is fixed to the lower end of the supporting fan 13 and connects to the linkage mechanism below. The movable rod 16 passes through the sliding groove 12 and performs stable radial linear motion under the restriction of the sliding groove 12. One end of the connecting rod 17 is fixed to the lower end of the movable rod 16 to convert the vertical motion of the bracket 10 into the radial motion of the movable rod 16. The end of the connecting rod 17 away from the movable rod 16 is fixed to the support platform 2 through the rotating shaft 18 to form a stable rotation fulcrum.

[0023] Working principle: The operator first activates the electric push rod 8 by controlling button 4, extending it and pushing rod 9 upward. Push rod 9 drives the cross bracket 10 to move vertically upward through fixing part 11. When the bracket 10 moves upward, it pulls the lower end of the movable rod 16 towards the center of the cross bracket 10, i.e., the inner side, through the connecting rod 17. Since the movable rod 16 passes through and is constrained by the sliding groove 12, the movable rod 16 drives the supporting fan 13 to retract synchronously towards the center along the sliding groove 12, so that the four clamping blocks 14 gather to the center position. At this time, the operator places the annular edging of the bottom of the circular filter screen to be assembled horizontally on the four retracted supporting fan 13. After placing it securely, the operator operates the control button 4 again to retract the electric push rod 8 in the opposite direction, pulling the push rod 9 downward. Push rod 9 drives the cross bracket 10 to move vertically upward through the fixing part 11. 11 drives the cross bracket 10 to move vertically downwards. When the bracket 10 moves downwards, it pushes the lower end of the movable rod 16 to move outwards away from the center through the connecting rod 17. The movable rod 16 drives the support fan 13 to expand outwards synchronously along the sliding groove 12, so that the four clamping blocks 14 move outwards radially synchronously and stably until the buffer pad 15 on the outside of the block tightly abuts against and clamps the inner edge of the annular edging. During this process, the buffer pad 15 is deformed by pressure and the clamping force is evenly distributed to effectively prevent workpiece damage. At this point, the annular edging is firmly and undamagedly fixed to the fixture. The operator then evenly applies adhesive to the upper surface of the inner side of the clamped and fixed annular edging. Finally, the circular filter screen is accurately placed on the annular edging coated with adhesive and pressure is applied to complete the bonding assembly. The heat dissipation hole 5 continuously dissipates heat during the process to ensure the stable operation of the electric push rod 8.
