Description

Technical Field

[0001] This invention relates to the field of clamp structures, and more particularly to a clamp and its components. Background Technology

[0002] Ultrasonic cleaning is a widely used cleaning technology that involves placing the lens and an ultrasonic generator in a liquid simultaneously. The cavitation effect of the ultrasonic waves removes dirt and stains from the lens surface. When immersing the lens, clamps are needed for positioning and fixing to avoid damaging the lens and affecting the cleaning quality. Current clamps can only be used to position and fix lenses of a certain size. When the length or width of the lens changes, it cannot be clamped back into the clamp. This means that different sizes of lenses in the same series cannot be positioned and fixed using the same clamp, resulting in the need to use different sizes of clamps for different lens sizes, leading to higher production costs and lower production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a clamp and its components that enable the clamp to position and fix lenses of different lengths and widths, while increasing the contact area between the outer surface of the lens and the cleaning fluid, thereby improving the cleaning effect.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A clamping assembly includes a base plate and a positioning unit disposed on the base plate. The positioning unit includes a clamping module and a support block for lifting a lens. The clamping module includes a first abutment and a second abutment disposed on opposite sides of the support block. The first abutment is fixedly disposed on the base plate. The base plate is provided with guide grooves extending toward the first abutment and the second abutment, respectively. The first abutment and the support block are both connected to the guide grooves in an adjustable manner. The first abutment and the second abutment are each provided with a vertically extending first slot that opens toward the support block. The top of the support block is provided with a horizontally extending second slot.

[0006] In the aforementioned clamping assembly, the bottom of the second slot is provided with a drain hole that penetrates the bottom of the support block, and the lower end of the drain hole is arranged opposite to the guide groove.

[0007] In the aforementioned clamping assembly, the support block includes a support block body and a slider connected to the guide groove in an adjustable manner; the support block body vertically penetrates the slider and is connected to the slider; the second slot is formed on the top of the support block body.

[0008] In the aforementioned clamping assembly, the bottom of the second slot is higher than the upper surface of the slider.

[0009] The aforementioned clamping assembly also includes a connecting module comprising two bolts; the bottom of the guide groove is open, and one of the bolts is threadedly connected to the support block and the other bolt is threadedly connected to the second abutment in a height-adjustable manner; the bolts abut against the bottom surface of the base plate through the nut end of the bolt, so that the support block and the second abutment are fixed on the guide rail.

[0010] In the aforementioned clamping assembly, the guide groove includes two parallel and spaced-apart grooves; both grooves extend toward the first abutment and the second abutment; two connecting modules are provided, each corresponding to one of the grooves.

[0011] In the aforementioned clamping assembly, the clamping module further includes two fixing seats, one of which is fixed to the base plate and connected to the first abutment post; the other fixing seat is connected to the guide groove in an adjustable manner and connected to the second abutment post.

[0012] In the aforementioned clamping assembly, a vertically extending mounting groove is provided on one side of the fixed base adjacent to the support block. The lower end of the mounting groove is provided with a chamfer to increase the open area, and the upper end of the mounting groove penetrates through the top of the fixed base. The first abutment and the second abutment are respectively fixed in their respective mounting grooves.

[0013] In the aforementioned clamping assembly, the guide grooves of two adjacent clamping assemblies are integrally formed.

[0014] A clamp includes a first connecting rod and a second connecting rod, and further includes a plurality of clamp assemblies as described above, wherein the plurality of clamp assemblies are arranged at intervals; a plurality of first abutments are connected to the first connecting rod, and a plurality of base plates are connected to the second connecting rod.

[0015] Compared with the prior art, the solution of the present invention has the following advantages:

[0016] 1. In the clamping assembly of the present invention, a first abutment and a second abutment hold the lens between them and position it in the length direction of the lens. The first abutment is fixed on the base plate, and the second abutment is disposed on the guide groove of the base plate. The guide groove extends toward the first abutment, and the second abutment moves closer to or away from the first abutment along the guide groove and is fixed at a preset position relative to the base plate. The distance between the first abutment and the second abutment can be adjusted by moving the second abutment to accommodate lenses of different lengths.

[0017] 2. In the clamp assembly of the present invention, both the first abutment and the second abutment are provided with a first slot for pressing against the lens. The first slot is a trapezoidal slot structure, so that the inner walls of the horizontal sides of the first slot have inclined surfaces. When the lens is pressed against the first slot, the edges of the horizontal sides of the lens are pressed against the corresponding inclined surfaces respectively. The inclined surfaces on both sides make the inner side of the first slot have different width distances, which can accommodate lenses of different widths. Lenses of different widths can be pressed against the first slot, while avoiding the outer surface of the lens from sticking to the first slot, increasing the contact area with the cleaning fluid, and improving the cleaning effect on the side of the lens.

[0018] 3. In the clamp assembly of the present invention, the support block can move along the guide groove to directly below the center of gravity of the lens, supporting the bottom of the lens. The support block, the first abutment, and the second abutment cooperate with each other to perform three-point positioning. The second slot on the support block is also a trapezoidal slot structure. The second slot abuts against the two sides of the lens to position the lens in the width direction, while suspending the lens directly above the bottom of the second slot, preventing the outer surface of the lens from sticking to the second slot, increasing the contact area with the cleaning fluid, and improving the cleaning effect on the bottom of the lens.

[0019] 4. In the fixture of the present invention, multiple fixture components are interconnected to form a fixture, which can simultaneously position and fix multiple lenses of different sizes and specifications, thereby improving the efficiency of batch cleaning and reducing the amount of consumables and energy consumption.

[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figure 1-11 As shown, the present invention provides a clamping assembly, including a base plate 1 and a positioning unit disposed on the base plate 1; the positioning unit includes a clamping module and a support block 4 for lifting a lens, the clamping module includes a first abutment 6 and a second abutment 8 disposed on opposite sides of the support block 4; the first abutment 6 is fixedly disposed on the base plate 1, the base plate 1 is provided with guide grooves extending toward the first abutment 6 and the second abutment 8 respectively, the first abutment 6 and the support block 4 are both connected to the guide grooves in an adjustable manner; the first abutment 6 and the second abutment 8 are each provided with a vertically extending first slot 7, and the top of the support block 4 is provided with a horizontally extending second slot 413.

[0037] In actual use, each component can be disassembled and assembled according to the amount of workpiece to be cleaned at one time. The first abutment 6 and the base plate 1 can be integrally formed or connected by bolts 9, rivets, pins and other components. In this embodiment, the connection method of the first abutment 6 is not restricted too much.

[0038] In addition, the first abutment 6 can be set on one side of the guide groove or on the guide groove of the bottom plate 1. The first abutment 6 set on the guide groove is connected to the guide groove in an adjustable manner, so that both abutments can be moved and adjusted. In this embodiment, the position of the first abutment 6 is not restricted too much.

[0039] Further improvements, combined with Figure 2 , Figure 6 , Figure 9 and Figure 11 As shown, the bottom of the second slot 413 is provided with a drain hole 412 that penetrates the bottom of the support block 4, and the lower end of the drain hole 412 is arranged opposite to the guide groove.

[0040] The drain groove allows the cleaning fluid in the second slot 413 to be quickly discharged from the drain hole 412 to the guide groove, and then discharged from the clamp through the guide groove, thus preventing the cleaning fluid from accumulating in the second slot 413. The bottom of the guide groove can be either open or closed, and this embodiment does not impose too many restrictions.

[0041] Combination Figure 2 , Figure 8 and Figure 9 As shown, the specific structure of the support block 4 is as follows: the support block 4 includes a support block body 41 and a slider 42 connected to the guide groove in an adjustable manner; the support block body 41 vertically penetrates the slider 42 and is connected to the slider 42; the second slot 413 is opened on the top of the support block body 41.

[0042] Preferably, the connection between the support block body 41 and the slider 42 is a snap-fit ​​connection. The specific structure of the snap-fit ​​connection is as follows: the slider 42 is provided with an inner cavity 422 that is adapted to the support block body 41. The inner cavity 422 penetrates the top and bottom of the slider 42, and the support block body 41 is located in the inner cavity 422; a positioning protrusion 414 is provided on the horizontal side of the support block 4; a positioning groove 421 communicating with the inner cavity 422 is opened at the bottom of the slider 42, and the positioning protrusion 414 is inserted into the positioning groove 421. The support block body 41 and the slider 42 are in contact with the upper surface of the base plate 1; in addition, the support block body 41 and the slider 42 are also connected by bolts 9 and pins. This embodiment does not impose too many restrictions on this.

[0043] Another improvement is that the bottom of the second slot 413 is higher than the upper surface of the slider 42.

[0044] The bottom of the second slot 413 is higher than the upper surface of the slider 42, so that when the lens comes into contact with the support block body 41, it avoids touching the slider 42 and prevents scratches, abrasions and other damage to the outer surface of the lens.

[0045] In practical applications, the support block body 41 is made of plastic, preferably Teflon or other plastic materials with a low coefficient of mechanical friction; the slider 42 is made of metal, such as stainless steel. This embodiment does not impose too many restrictions on the materials of the support block body 41 and the slider 42.

[0046] The bottom of the guide channel is open, which allows the water in the guide channel to drain out quickly from the bottom, while reducing the resistance when the clamp is removed from the cleaning fluid and making it easier to remove.

[0047] Combination Figure 10 and Figure 11 As shown, in this embodiment, a connecting module is also included, which includes two bolts 9; the bottom of the guide groove is open, and one of the bolts 9 and the support block 4 and the other bolt 9 and the second abutment 8 are threadedly connected in a height-adjustable manner; the bolts 9 abut against the bottom surface of the base plate 1 through the nut end of the bolts 9, so that the support block 4 and the second abutment 8 are fixed on the guide rail.

[0048] In some embodiments, in addition to using bolts 9 to fix the support block 4 and the second abutment 8 to the guide rail, grommets can also be used to fix the support block 4 and the second abutment 8 to the guide rail. Threaded holes are opened on the side of the base plate 1, and the threaded holes are connected to the guide groove. Grommets are connected to the threaded holes. The bottom of the support block 4 and the second abutment 8 is provided with protrusions extending into the guide groove. When the grommets abut against the protrusions, the support block 4 and the second abutment 8 are fixed to the guide rail.

[0049] When a bolt 9 is provided at the bottom of the support block 4 and the bottom of the second abutment 8, a protrusion extending into the guide groove can be provided at the bottom of the support block 4 and the second abutment 8 respectively. The cross-section of the protrusion is a non-circular structure such as polygon or ellipse, which avoids relative rotation of the support block 4 and the second abutment 8 on the guide groove, and at the same time improves the installation accuracy and orientation accuracy when fixing.

[0050] In a further preferred embodiment, the guide groove includes two parallel and spaced-apart grooves 11; both grooves 11 extend toward the first abutment 6 and the second abutment 8; two connecting modules are provided, and are respectively arranged in one-to-one correspondence with the grooves 11.

[0051] There are two connecting modules, namely, two bolts 9 are provided at the bottom of the support block 4 and the second abutment 8. The two bolts 9 of one connecting module are located in the corresponding guide grooves to avoid relative rotation of the support block 4 and the second abutment 8 on the guide grooves, which would affect the accuracy and positioning and fixing effect.

[0052] Combination Figure 2 , Figure 6 , Figure 9 and Figure 11 As shown, in practical applications, there are two drain holes 412, which are arranged at intervals. The two drain holes 412 correspond one-to-one with the two troughs 11. The support block 4 improves the drainage efficiency by increasing the number of drain holes 412. The bottom of the second slot 413 is also provided with a recess 411. The two drain holes 412 are opened in the recess 411. The recess 411 forms a countersunk head at the bottom of the second slot 413 that connects the upper ends of the two drain holes 412. The water that falls into the countersunk head can be discharged from either drain hole 412, thereby improving the drainage efficiency.

[0053] In another preferred embodiment, two bolts 9 located at the bottom of the support block 4 are arranged opposite each other on both sides of the length direction of the second slot 413, which reduces the width distance of the support block 4, reduces the volume of the support block 4, and at the same time shortens the distance between the two slots 11, reduces the width required for the base plate 1, reduces the weight and saves materials.

[0054] In practical use, the two bolts 9 at the bottom of the support block 4 are respectively in the corresponding groove 11 and are located on both sides of the support block 4, so that the two bolts 9 are staggered in the length direction of the groove 11. Correspondingly, the two grooves 11 are staggered, that is, the ends of the two grooves 11 on the same side are set in a non-aligned manner. When the support block 4 moves to the end of the guide groove, the two bolts 9 of the support block 4 simultaneously abut against the end of the corresponding groove 11. Similarly, the two bolts 9 at the bottom of the second abutment 8 are set on both sides of the second abutment 8 along the length direction of the second slot 413, that is, staggered along the length direction of the second slot 413. When the second abutment 8 moves to the end of the guide groove, the two bolts 9 of the second abutment 8 abut against the end of the corresponding groove 11.

[0055] Combination Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, in another preferred embodiment, the top of the first slot 7 is open, so that when the first slot 7 is pressed against the lens, the lens can be exposed outside the first slot 7, thereby removing the height restriction of the first slot 7 on the lens. At the same time, it avoids the need to increase the length of the first slot 7 to accommodate lenses of different heights, saving materials and improving stability. In another preferred embodiment, the bottom of the first slot 7 is open, so that water accumulated in the first slot 7 can be quickly drained out of the first slot 7. Similarly, both ends of the second slot 413 are open, so that water accumulated in the second slot 413 can be quickly drained from both ends, while avoiding the need to increase the length of the second slot 413 to accommodate lenses of different lengths.

[0056] In this embodiment, the clamping module further includes two fixing seats 5, one of which is fixed on the base plate 1 and connected to the first abutment post 6; the other fixing seat 5 is connected to the guide groove in an adjustable manner and is connected to the second clamping post.

[0057] The first abutment 6 and the second abutment 8 are respectively fixed on the corresponding fixed base 5 to avoid direct contact with the base plate 1 and prevent wear.

[0058] like Figure 3 As shown, the specific structure of the fixing seat 5 is as follows: a vertically extending mounting groove is provided on one side of the fixing seat 5 adjacent to the support block 4; the lower end of the mounting groove is provided with a chamfer 51 for increasing the open area; the upper end of the mounting groove penetrates the top of the fixing seat 5; the first abutment 6 and the second abutment 8 are respectively fixed in the corresponding mounting groove.

[0059] The chamfer 51 increases the open area of ​​the first slot 7, avoiding assembly interference with the lens, and also guides the water accumulated in the mounting groove to drain quickly. The upper end of the mounting groove is open, allowing the lens that is pressed against the first slot 7 to be exposed outside the mounting groove, avoiding the upper end of the mounting groove from restricting the height of the lens, and also avoiding the need to increase the length of the mounting groove to accommodate lenses of different heights.

[0060] In practical applications, the first abutment 6 and the second abutment 8 are made of plastic, preferably Teflon or other plastic materials with a low coefficient of mechanical friction; the fixing seat 5 is made of metal, such as iron and stainless steel. This embodiment does not impose too many restrictions on the materials of the first abutment 6, the second abutment 8, and the fixing seat 5.

[0061] In some embodiments, such as Figure 2 As shown, the guide grooves of the two adjacent clamping assemblies are integrally formed, allowing two lenses of different sizes to be positioned and fixed on a single base plate 1, thereby improving space utilization and batch cleaning efficiency.

[0062] A clamp, combined Figure 1 , Figure 4 and Figure 10 As shown, it includes a first connecting rod 3 and a second connecting rod 2, and also includes a plurality of clamping assemblies as described above, with the plurality of clamping assemblies arranged at intervals; a plurality of first abutments 6 are all connected to the first connecting rod 3, and a plurality of base plates 1 are all connected to the second connecting rod 2.

[0063] Multiple clamping components are arranged at intervals and fixed to each other by the first connecting rod 3 and the second connecting rod 2, forming a clamp that can hold multiple clamps of different sizes and specifications, thus improving the efficiency of batch cleaning. The spacing between adjacent clamping components allows the clamping components in the middle of the clamp to be quickly immersed in the cleaning solution. When the clamp is removed, the water accumulated at the clamping components in the middle of the clamp can be quickly drained from the spacing, avoiding water accumulation on the clamp and reducing the resistance when removing the clamp, thus reducing the difficulty of removal.

[0064] In summary, the fixture in this technical solution can accommodate the positioning and fixing of lenses of different sizes and specifications. Even when the length or width of the lens changes, it can still be clamped onto the fixture. This allows different sizes of lenses in the same series to be positioned and fixed using the same fixture, which has wide applicability and practicality. It eliminates the need to convert fixtures to corresponding specifications for different lens sizes, thereby reducing production costs and improving production efficiency.

[0065] The above description is only a partial embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
