Description
Technical Field
[0001] This application relates to the field of cutting fixtures, and in particular to a rubber strip trimming and cutting fixture. Background Technology
[0002] Sealing strips are a crucial component of automobiles, primarily used in doors, windows, and trunks to provide waterproofing, sound insulation, dustproofing, and shock absorption. Currently, most sealing strips are rectangular. To ensure they can be applied to multiple areas for optimal results, trimming and cutting are often necessary. In response to the aforementioned issues, the inventor provides a sealing strip trimming and cutting fixture. Utility Model Content
[0003] To improve the trimming accuracy of rubber strips, this application provides a rubber strip trimming and cutting fixture.
[0004] The technical solution of the rubber strip trimming and cutting fixture provided in this application is as follows:
[0005] A rubber strip trimming and cutting fixture includes a frame, a clamping assembly mounted on the top surface of the frame for clamping the rubber strip, a demolding assembly for driving the rubber strip out of the clamping assembly, and a cutting assembly for trimming the rubber strip. The clamping assembly includes a clamping base mounted on the top surface of the frame, a fixing seat fixed to one side of the clamping base, and a sliding seat slidably mounted on the top surface of the clamping base. The fixing seat has a first clamping groove for arranging the rubber strip, and the sliding seat has a second clamping groove that cooperates with the first clamping groove to clamp the rubber strip. The top surfaces of the fixing seat and the sliding seat are arc surfaces with the same curvature.
[0006] By adopting the above technical solution, in the trimming process of the rubber strip, the rubber strip is first arranged in the first clamping groove and the second clamping groove. The rubber strip is fixed in the clamping assembly by sliding the sliding seat towards the fixed seat. Then, the cutting assembly cuts off the excess part of the rubber strip along the arc surface of the top surface of the fixed seat and the sliding seat. The sliding seat then slides away from the fixed seat, and the rubber strip is pushed out of the clamping assembly by the driving of the demolding assembly, thus completing the trimming process of the rubber strip. Through the cooperation between the clamping assembly, the cutting assembly, and the demolding assembly, a rapid trimming process of the rubber strip is achieved, which helps to improve the trimming efficiency and trimming accuracy of the rubber strip.
[0007] Optionally, the sliding seat and the clamping base are locked together by a locking structure, the locking structure including a locking base installed on the top surface of the clamping base, a locking groove opened on the top surface of the locking base, an arrangement groove opened on the bottom of the sliding seat and cooperating with the locking base, and a locking block arranged on the top surface of the arrangement groove and cooperating with the locking groove.
[0008] By adopting the above technical solution, the specific structure of the locking structure between the sliding seat and the clamping base is disclosed. The sliding seat is locked onto the clamping base through the cooperation between the locking block and the locking groove. When the sliding block is locked, the adhesive strip is clamped between the fixed base and the sliding seat, which helps reduce the probability of the adhesive strip shifting during the trimming process, ensuring the trimming accuracy of the adhesive strip. When it is necessary to unlock the sliding seat, simply lift the sliding seat slightly upwards and drive it to slide away from the fixed base. The cooperation between the locking base and the arrangement groove helps guide the sliding of the sliding seat, reducing the probability of the sliding seat shifting during the sliding process and helping to improve the trimming efficiency of the adhesive strip.
[0009] Optionally, the clamping base has a sliding groove for the sliding seat to slide, and the clamping base is provided with a limiting block on one side of the sliding groove for restricting the sliding seat.
[0010] By adopting the above technical solution, the sliding groove helps to provide a platform for the sliding seat to slide, and the limiting block helps to restrict the sliding seat to slide, reducing the probability of the sliding seat falling out of the sliding groove.
[0011] Optionally, the sliding seat is provided with limit posts on both sides, the sliding seat has an installation through groove that runs through the upper and lower sides of the sliding seat and is used for arranging the limit posts, the bottom surface of the limit posts has a limit protrusion, and the clamping base has a fixing groove for arranging the limit protrusion.
[0012] By adopting the above technical solution, the cooperation between the upper limit protrusion of the limiting post and the fixing groove on the clamping base helps to further restrict the sliding seat, reduce the probability of the sliding seat loosening during processing, and improve the trimming accuracy of the rubber strip.
[0013] Optionally, the demolding assembly includes a demolding base mounted on one side of the fixed base, a sliding block slidably mounted on the top surface of the demolding base, and a sliding push rod connected to the side of the sliding block facing the fixed base and used to push the adhesive strip out from the first clamping groove and the second clamping groove; the demolding base has a mounting groove for the sliding push rod to pass through, the top surface of the demolding base is provided with a guide rail for guiding the sliding of the sliding block, and the sliding block has a guide groove that cooperates with the guide rail.
[0014] By adopting the above technical solution, the specific structure of the demolding assembly is disclosed. When the driving rubber strip is disengaged from the first and second clamping grooves, the sliding block slides towards the clamping assembly, causing the sliding push rod connected to one side of the sliding block to push the rubber strip away from the clamping assembly, thus disengaging part of the rubber strip from the clamping assembly. The operator then collects the trimmed rubber strip. The cooperation between the guide rail and the guide groove helps to guide the sliding process of the sliding block.
[0015] Optionally, the top surface of the demolding base is provided with mounting grooves spaced apart on both sides of the guide slide along the width direction of the demolding base.
[0016] By adopting the above technical solution, the setting of the mounting groove on the top surface of the demolding base helps to reduce the contact area between the bottom surface of the sliding block and the top surface of the demolding base, thereby ensuring the smooth sliding of the sliding block on the plane of the demolding base and helping to improve the trimming efficiency of the rubber strip.
[0017] Optionally, the guide rail has an upwardly protruding limiting protrusion on the side away from the fixed seat to prevent the sliding block from dislodging from the guide rail.
[0018] By adopting the above technical solution, the setting of the upper limit protrusion on the side of the guide rail away from the fixed seat helps to reduce the probability of the sliding block falling off the guide rail.
[0019] Optionally, the demolding base has an abutment surface for one side of the adhesive strip to abut.
[0020] By adopting the above technical solution, the setting of the contact surface on the demolding base helps to position the rubber strip in the rubber strip trimming and cutting fixture, thereby improving the trimming accuracy and trimming efficiency of the rubber strip.
[0021] Optionally, an unlocking handle is provided on the side of the sliding seat facing away from the fixed seat.
[0022] By adopting the above technical solution, the setting of the unlocking handle on the side of the sliding seat facing away from the fixed seat helps to slide the sliding seat, realize the clamping and releasing of the rubber strip by the rubber strip trimming and cutting fixture, and help to improve the trimming efficiency of the rubber strip.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. A rubber strip trimming and cutting fixture, which clamps the rubber strip with a clamping component, cuts off the part of the rubber strip that protrudes from the sliding seat and the fixed seat with a cutting component, and finally pushes the rubber strip out of the clamping component with a demolding component, which helps to realize the rapid trimming process of the rubber strip and achieve ideal trimming accuracy.
[0025] 2. The locking structure between the sliding seat and the clamping base helps reduce the probability of the rubber strip shifting during the trimming process, ensuring the trimming accuracy of the rubber strip;
[0026] 3. The upper limit protrusion on the side of the guide rail away from the fixed seat helps to reduce the probability of the sliding block detaching from the guide rail. Attached Figure Description

A clamping gap 24 for arranging adhesive strips is provided between the fixing seat 22 and the sliding seat 23. The fixing seat 22 has a first clamping groove 221 for arranging adhesive strips, and the sliding seat 23 has a second clamping groove 231 for arranging adhesive strips and cooperating with the first clamping groove 221 to clamp the adhesive strips. The clamping base 21 has a sliding groove 211 for sliding the sliding seat 23, and an abutment block 212 for limiting the sliding seat 23 is provided on the side of the clamping base 211 away from the fixing seat 22. To facilitate pushing the sliding base 23, an unlocking handle 232 is provided on the side of the sliding base 23 away from the fixed base 22. In this embodiment, there are two unlocking handles 232, which are symmetrically arranged on the sliding base 23.
[0036] Reference Figure 1 and Figure 3 To reduce the probability of the adhesive strip shifting during the trimming process, a locking structure is used to lock the sliding base 23 and the clamping base 21 together. The locking structure includes a locking base 251 mounted on the top surface of the clamping base 21, a locking groove 2511 formed on the top surface of the locking base 251, an arrangement groove 233 formed on the bottom of the sliding base 23 and cooperating with the locking base 251, and a locking block 252 arranged on the top surface of the arrangement groove 233 and cooperating with the locking groove 2511. The locking block 252 has a chamfered structure to enable quick locking and unlocking between the sliding base 23 and the clamping base 21. The clamping base 21 has a mounting groove 213 for accommodating the locking base 251, and the locking base 251 is fixed in the mounting groove 213 with screws. The locking base 251 on the clamping base 21 and the arrangement groove 233 on the sliding base 23 act as a slide rail and a slide groove, which helps to guide the sliding process of the sliding base 23 and reduce the probability of the sliding base 23 shifting during the sliding process. In this embodiment, three locking bases 251 are evenly spaced along the length direction of the clamping base 21, and the bottom surface of the sliding base 23 is evenly spaced along the length direction of the sliding base 23, with arrangement grooves 233 and locking blocks 252 that cooperate with the locking bases 251.

[0039] The implementation principle of the rubber strip trimming and cutting fixture in this application embodiment is as follows: During the trimming process of the rubber strip, the rubber strip is first arranged in the clamping gap 24 between the fixed seat 22 and the sliding seat 23. The rubber strip is clamped between the first clamping groove 221 and the second clamping groove 231 by the sliding seat 23 sliding towards the fixed seat 22. Then, the protruding part of the rubber sleeve is cut along the top surface of the fixed seat 22 and the sliding seat 23 by the cutting component 3. Then, the sliding seat 23 is slightly lifted upward and driven to slide away from the fixed seat 22. Finally, part of the rubber strip is pushed out from the clamping gap 24 by the demolding component 4 and the trimmed rubber strip is collected. The cooperation between the clamping component 2, the cutting component 3 and the demolding component 4 helps to improve the trimming accuracy and trimming efficiency of the rubber strip.
