Description

Technical Field

[0001] This utility model relates to the field of glassware coloring and processing technology, and in particular to a fixture for glassware production. Background Technology

[0002] In the glassware production process, fixtures are key tooling equipment, and their structural stability and adaptability directly affect the product qualification rate and production efficiency.

[0003] However, existing technologies, such as Chinese Publication No. CN212553332U, describe a clamp for glassware production. This clamp includes a device body with an upper baffle on its upper outer surface and a clamping mechanism on one outer surface. The device body contains a motor and a brake box, with the motor located above the brake box. A fixed base is located on the lower outer surface of the device body. This invention, a clamp for glassware production, uses a motor inside the device body to drive the brake box. The brake box, through a piston device, drives the piston rod in the clamping mechanism. The clamping mechanism has two sets, each tightly attached to both ends of the glassware. When clamping the glassware, the buffer pad of the movable disc cushions and relieves force, preventing breakage due to excessive clamping. The movable rod allows for rotation of the glassware, making operation convenient and offering better prospects for future use.

[0004] However, during use, it was found that the movable rods of this device's clamps are mostly connected to the movable disk via a single movable slot. The length of the movable rods is fixed and lacks multi-angle adjustment, resulting in a limited clamping range. For glassware of different sizes, irregularly shaped products, and workpieces of different heights, the existing structure cannot achieve precise alignment and clamping, requiring frequent clamp changes, which increases production changeover time and costs. Furthermore, in terms of cushioning and protection, the existing device relies solely on a single buffer pad in contact with the glassware. Since glassware, especially thin-walled products, has poor impact resistance, uneven force distribution during clamping can easily lead to localized stress concentration. When the clamping force exceeds the glass's withstand threshold, it can easily cause the product to break, especially in the production of high-precision optical glass or art glass, where such defects can cause serious economic losses. Utility Model Content

[0005] The purpose of this invention is to solve the problems of poor adaptability and insufficient buffer protection in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fixture for glassware production, comprising: a conveyor table; lifting components, fixedly connected to the four corners of the bottom of the conveyor table, and having casters installed at the bottom; a set of mounting frames, symmetrically installed on the left and right sides above the conveyor table, with multiple sets of clamping components installed at their upper ends; connecting arms, in the shape of an inverted L, fixedly connected to the opposite side of the set of mounting frames, and having a fixing block connected to their bottom; and a fixing platform, installed at the bottom of the conveyor table, with a power component at its upper end, which allows the set of connecting arms to move relative to each other.

[0007] The technical advantages of adopting the above-mentioned further solution are as follows: the workpiece is carried by a conveyor table, and the bottom lifting assembly with casters enables height adjustment and movement. The multiple clamping assemblies of the mounting brackets on both sides can be driven by a power assembly to move the connecting arms relative to each other, and the glassware is stably clamped with the help of fixed blocks, thereby improving the flexibility and stability of conveying and clamping during production.

[0008] In a preferred embodiment, the clamping assembly includes: a mounting post disposed above the mounting frame, with a plurality of limiting holes through its outer surface; a clamping frame disposed on one side of the mounting post; a connecting post fixedly connected to one side of the clamping frame, with one end passing through the limiting holes and fixedly connected to a limiting block; a rotating shaft rotatably disposed at the front end of the clamping frame; and a clamping roller rotatably disposed outside the rotating shaft.

[0009] The technical advantage of adopting the above-mentioned further solution is that the position of the clamping frame can be adjusted by using the limiting hole of the mounting column in conjunction with the connecting column and the limiting block. The rotating shaft at the front end of the clamping frame drives the clamping roller to rotate, which can not only adapt to different sizes by adjusting the position when clamping glassware, but also reduce friction by using the rotation of the roller, thereby improving the clamping adaptability and safety.

[0010] In a preferred embodiment, the clamping assembly further includes: a fixed stud, fixedly connected to the upper end of the mounting bracket; a movable cylinder, movably disposed on the outer surface of the fixed stud; and a connecting block, fixedly connected to the upper end of the movable cylinder and rotatably connected to the mounting stud.

[0011] The technical advantage of adopting the above-mentioned further solution is that the movable cylinder drives the connecting block to move up and down along the axis of the fixed stud, enabling vertical height adjustment of the mounting column, clamping frame, and clamping rollers. Combined with the original position adjustment function, it can adapt to glassware of different heights and sizes, further improving clamping flexibility and applicability.

[0012] In a preferred embodiment, the power assembly includes: a bidirectional lead screw, disposed above the fixed platform, with both ends passing through a set of oppositely disposed fixed blocks; a driven gear, fixedly connected to the bidirectional lead screw; a transmission gear, disposed on one side of the driven gear and cooperating with the driven gear; and a drive motor, disposed on one side of the transmission gear, with its output end fixedly connected to the transmission gear via a connecting shaft.

[0013] The technical advantage of adopting the above-mentioned further solution is that the drive motor drives the transmission gear to rotate via the connecting shaft, and the transmission gear meshes with the driven gear to rotate the bidirectional lead screw. The bidirectional lead screw passes through the fixed block, and when it rotates, it drives a set of fixed blocks and connecting arms to move relative to each other, realizing the synchronous opening and closing adjustment of the clamping components on both sides, accurately controlling the clamping force and spacing, and improving the stability and efficiency of clamping glassware.

[0014] In a preferred embodiment, the clamping assembly further includes: a buffer elastic sleeve fitted on the outer surface of the clamping roller; and a reset spring fitted on the outer surface of the connecting column, with its two ends respectively abutting against the limiting block and the mounting column.

[0015] The technical effects of adopting the above-mentioned further solution are: the buffer elastic sleeve is fitted outside the clamping roller to reduce the hard friction and collision of the glassware during clamping; the reset spring is fitted on the connecting column to buffer the clamping force through elastic force.

[0016] In a preferred embodiment, the lifting assembly includes: a fixed column disposed at the bottom of the conveyor table; a movable column movably sleeved on the outside of the fixed column; a through hole disposed through the outside of the fixed column and the movable column; and a limiting bolt movably disposed in the through hole.

[0017] The technical advantage of adopting the above-mentioned further solution is that: the movable column is sleeved outside the fixed column to achieve telescopic movement, and the position is fixed by through holes and limit bolts. During adjustment, the bolts are loosened to adjust the height of the movable column, and then the bolts are locked to fix it. The height of the conveyor table and the clamping structure above can be flexibly adjusted to adapt to the height requirements of different production scenarios, thereby improving the overall height adaptability and flexibility of the device.

[0018] In a preferred embodiment, the power assembly further includes: a limiting rod, which is disposed on the left and right sides of the bidirectional lead screw, and its two ends are disposed through a set of oppositely disposed fixing blocks.

[0019] The technical effect of adopting the above-mentioned further solution is that when the bidirectional screw drives the fixed block and the connecting arm to move relative to each other, the limiting rod restricts the displacement of the fixed block, ensuring that the clamping components on both sides open and close smoothly along a straight line.

[0020] In a preferred embodiment, the upper end of the conveyor table is symmetrically provided with two sets of limiting guide grooves, and the bottom of the mounting frame is provided with limiting blocks, and the limiting blocks cooperate with the limiting guide grooves.

[0021] The technical effect of adopting the above-mentioned further solution is that the limiting guide groove and the limiting block at the bottom of the mounting frame cooperate with each other. When the power component drives the mounting frame to move, the guide groove guides and limits the block to prevent the mounting frame from deviating.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] This invention utilizes the telescopic cooperation between the fixed and movable columns in the lifting assembly, combined with a fixing method using multiple sets of through holes and limiting bolts, to flexibly adjust the overall height of the conveyor table, adapting to production lines or processing stations of varying heights. The clamping assembly achieves height adjustment through the lifting and lowering of the movable cylinder along the fixed studs. Combined with the installation of the connecting column in different limiting holes on the mounting column, it allows for precise adjustment of the base height position of the clamping frame. Simultaneously, the power assembly drives the mounting frame to move relative to each other via a bidirectional screw drive, quickly adjusting the spacing between the clamping assemblies on both sides. This multi-dimensional adjustment design allows the device to easily adapt to various product specifications, from small cups to large vessels, without requiring a complete replacement of the clamping structure, significantly reducing changeover time costs and improving production flexibility.

[0024] This invention constructs a comprehensive protection system through a dual-buffer design. The return spring on the outer surface of the connecting column in the clamping assembly forms an elastic buffer mechanism. When the clamping roller contacts the glassware, the return spring can adaptively adjust the clamping force through compression, avoiding the impact force generated by rigid contact. Simultaneously, the buffer elastic sleeve on the outer surface of the clamping roller is made of flexible material, which increases friction with the glassware surface to prevent slippage and absorbs vibration and pressure during clamping through material deformation, further reducing the risk of breakage. Furthermore, the free rotation of the clamping roller's shaft allows the clamping action to form a rolling engagement with the glassware transport, reducing relative friction and wear on the glassware surface. This dual-buffer protection structure effectively solves the product breakage problem caused by insufficient buffering in traditional clamps, significantly improving the yield rate in glassware production and reducing production costs.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1:

[0034] Please see Figure 1-5 This embodiment provides a fixture for glassware production, including a conveyor table 1 as the basic load-bearing component, lifting components 2 installed at the four corners of the bottom to provide stable support and height adjustment functions for the equipment, and casters 8 at the bottom of the lifting components 2 to give the equipment the ability to move flexibly, making it convenient to adjust the position in the production workshop according to the process requirements.

[0035] A set of mounting brackets 3 is symmetrically installed on the left and right sides above the conveyor table 1, serving as the mounting carrier for the clamping components. An inverted L-shaped connecting arm 4 is fixedly connected to the opposite side of each mounting bracket 3. The bottom of the connecting arm 4 is connected to a power assembly 5 on the bottom fixed platform 7 of the conveyor table 1 via a fixing block 9. The power assembly 5 can drive the connecting arm 4 to move relative to each other, thereby causing the mounting brackets 3 to move synchronously relative to each other, thus adjusting the clamping range for glassware of different widths.

[0036] Meanwhile, the limiting guide grooves 11 symmetrically arranged at the upper end of the conveyor table 1 cooperate with the limiting block 10 at the bottom of the mounting frame 3 to provide guidance for the movement of the mounting frame 3 and ensure the stability of the movement process.

[0037] The clamping assembly 6 is mounted on the upper end of the mounting frame 3 via a fixing stud 611. The movable cylinder 610, which is movably sleeved on the outer surface of the fixing stud 611, can move up and down along its axis. The connecting block 609 at the upper end of the movable cylinder 610 is rotatably connected to the mounting column 601, so that the mounting column 601 can rise and fall synchronously with the movable cylinder 610, thereby realizing the adjustment of the clamping height.

[0038] Multiple limiting holes 602 penetrating the outer surface of the mounting post 601 are used to install the connecting post 604. One end of the connecting post 604 is fixedly connected to the clamping frame 603, and the other end passes through the limiting hole 602 and is limited by the limiting block 612. The return spring 608 sleeved on the outer surface of the connecting post 604 abuts against the limiting block 612 and the mounting post 601 at both ends, providing elastic cushioning for the clamping frame 603. The clamping roller 606 is rotatably mounted on the external rotating shaft 605 at the front end of the clamping frame 603. The cushioning elastic sleeve 607 sleeved on the outer surface of the clamping roller 606 can effectively protect the surface of the glassware from damage. By selecting different positions of the limiting hole 602 to install the connecting post 604, the base height of the clamping frame 603 can be adjusted. With the micro-motion lifting adjustment of the movable cylinder 610, the clamping roller 606 can adapt to the clamping needs of glassware of different sizes.

[0039] Example 2:

[0040] like Figures 1-5 As shown, based on Embodiment 1, this embodiment focuses on optimizing the height adjustment function of the device, specifically including:

[0041] The lifting assembly 2 specifically consists of a fixed column 201, a movable column 202, through holes 203, and limiting bolts 204. The fixed column 201 is vertically installed at the bottom of the conveyor table 1, and the movable column 202 is movably sleeved on the outside of the fixed column 201, allowing them to extend and retract relative to each other. Multiple through holes 203 are provided at corresponding positions on the outer surfaces of the fixed column 201 and the movable column 202. When the height of the conveyor table 1 needs to be adjusted, the movable column 202 can be pulled up or down to align the through holes 203 on the fixed column 201 and the movable column 202. Then, the limiting bolts 204 are inserted into the aligned through holes 203, thus fixing the fixed column 201 and the movable column 202 relative to each other and completing the height adjustment of the equipment.

[0042] By selecting through holes 203 of different heights for fixing, the equipment height requirements in different production scenarios can be met, thus enhancing the applicability of the equipment.

[0043] Example 3:

[0044] like Figures 1-5 As shown, based on Embodiment 2, this embodiment adds a power transmission and stability auxiliary structure, specifically including:

[0045] The core of the power assembly 5 is a bidirectional lead screw 501, which is mounted above the fixed platform 7. A set of opposing fixed blocks 9 pass through both ends and are threaded into it. The driven gear 502 fixed on the bidirectional lead screw 501 meshes with the transmission gear 503 on the output shaft 505 of the drive motor 504. When the drive motor 504 is working, it drives the bidirectional lead screw 501 to rotate through the transmission of the transmission gear 503 and the driven gear 502. Utilizing the threaded transmission characteristics of the bidirectional lead screw 501, the fixed blocks 9 on both sides drive the connecting arm 4 and the mounting bracket 3 to make precise relative movements.

[0046] To enhance the stability of power transmission, limiting rods 506 are provided on both sides of the bidirectional lead screw 501. The two ends of the limiting rods 506 pass through the fixing blocks 9 and are arranged parallel to the bidirectional lead screw 501. When the bidirectional lead screw 501 drives the fixing blocks 9 to move, the limiting rods 506 restrict the fixing blocks 9 from rotating with the lead screw, ensuring that the mounting frame 3 always moves smoothly in a straight line and improving the reliability of the clamping process.

[0047] Working principle: This equipment is a fixture for glassware production. When using it, first use the casters 8 to move the device to a suitable position, then adjust the height of the equipment according to production needs, loosen the limit bolts 204 of the lifting component 2, pull the movable column 202 up and down to align the fixed column 201 with the through hole 203 on the movable column 202, insert the limit bolts 204 to fix it, and complete the height adjustment of the conveyor table 1 to adapt to different production line heights.

[0048] Next, adjust the clamping assembly 6, move the movable cylinder 610 up and down along the fixed stud 611, drive the mounting column 601 to adjust the height, select the appropriate limiting hole 602 to install the connecting column 604, fix it by the limiting block 612, adjust the basic height position of the clamping frame 603 to ensure that the clamping roller 606 is aligned with the glassware clamping point.

[0049] When the equipment is started, the drive motor 504 drives the transmission gear 503 to rotate via the connecting shaft 505. The transmission gear 503 meshes with the driven gear 502, causing the bidirectional lead screw 501 to rotate. The bidirectional lead screw 501 is threadedly engaged with the fixed block 9. Guided by the limit rod 506, it drives the connecting arms 4 on both sides to move the mounting frame 3 relative to each other. The limit block 10 at the bottom of the mounting frame 3 slides along the limit guide groove 11 of the conveyor table 1 to ensure smooth movement until the clamping components 6 on both sides approach the glassware.

[0050] During clamping, when the glassware contacts the clamping roller 606, the clamping frame 603 is pushed, causing the connecting column 604 to move backward. The return spring 608 is compressed, generating elastic force, which makes the clamping roller 606 fit tightly against the surface of the glassware. The clamping roller 606 can rotate freely via the rotating shaft 605, reducing friction in conjunction with the glassware conveying action. The buffer elastic sleeve 607 on the outer surface prevents excessive clamping force from damaging the glassware. When it is necessary to change to different sizes of glassware, the height and horizontal position of the clamping assembly 6 can be repeatedly adjusted. The power assembly 5 can quickly adjust the clamping spacing without the need for disassembly and reinstallation.

[0051] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
