Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting technology, and in particular to a sheet metal cutting clamping structure for a refrigeration machine casing. Background Technology

[0002] The main purpose of the sheet metal cutting clamp fixing structure design for the refrigeration machine casing is to ensure that the clamp can fit and firmly fix the sheet metal parts of the casing when cutting, processing or other operations are performed. In this way, the sheet metal parts of the casing can be stably kept from shifting or deforming during the cutting process, thereby ensuring the cutting accuracy and processing quality.

[0003] However, the existing sheet metal cutting clamping structure for refrigeration machine casings has certain limitations in its design, mainly in the lack of an effective adjustment mechanism. Specifically, the existing structure cannot be adjusted according to the thickness of different sheet metal parts. This means that in actual use, whenever sheet metal parts of different thicknesses need to be clamped, the clamping force and contact surface may not be precisely matched. If the clamping force cannot be adjusted for sheet metal parts of different thicknesses, it may lead to over-clamping or insufficient clamping force. Over-clamping will cause deformation or damage to the sheet metal parts, while insufficient clamping force will not effectively prevent the casing from moving, resulting in cutting errors. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the clamping force and contact surface of the clamping plate may not be accurately matched when clamping sheet metal parts of different thicknesses, as the clamping cannot be adjusted according to the thickness of different sheet metal parts.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sheet metal cutting clamp fixing structure for a freezer casing, including a base, a sheet metal part being provided on the top of the base, and support members being provided on both sides of the top of the base, and further including:

[0006] Both rotating rods are movably embedded inside the rear side of the support member, and both rotating rods are fixedly mounted with forward rotating screws on their front sides;

[0007] Two reverse lead screws are fixedly installed on the front side of the forward lead screw. The front outer surfaces of the two reverse lead screws are movably embedded in the inner front side of the support member. The outer surfaces of the two forward lead screws and the two reverse lead screws are threadedly connected to sliders.

[0008] Two first sliding grooves are formed on the top side of the inner wall of the support member. The four sliders are divided into two groups of two, and the top outer surfaces of the two groups of sliders are slidably connected to the inner surface of the first sliding groove.

[0009] In a preferred embodiment, each of the four sliders is movably connected to a support rod on both sides, and the other end of each of the eight support rods is movably connected to a hinge. The eight hinges are divided into two groups of four.

[0010] The technical effect of adopting the above-mentioned further solution is that it enables the slider to push the support rod to flip through the hinge when sliding in opposite directions.

[0011] In a preferred embodiment, a clamping plate body is fixedly installed at the bottom of both sets of hinges, and a limiting groove is opened on both sides of the inner wall of the two supports. Both sides of the clamping plate body are slidably connected to the inner surface of the limiting groove.

[0012] The technical effect of adopting the above-mentioned further solution is that when the support rod flips, the clamping plate body can be pushed downward through the hinge, so that the clamping plate body can slide downward through the limiting groove mechanism.

[0013] In a preferred embodiment, the bottom of both clamping plates is provided with rubber pads, the outer surface of both rotating rods is fixedly fitted with limiting gears, and the rear side of both support members is fixedly installed with connecting columns.

[0014] The technical effect of adopting the above-mentioned further solution is that the rubber pad can be driven by the clamping plate to adhere to the top of the sheet metal part, so as to clamp and fix it.

[0015] In a preferred embodiment, the outer surfaces of the two connecting columns are slidably connected to limit blocks, the tops of the two limit blocks are provided with teeth, and the rear sides of the two rotating rods are fixedly installed with crank handles.

[0016] The technical effect of adopting the above-mentioned further solution is that it can push the limiting block, causing it to slide forward through the connecting column to disengage from the limiting gear.

[0017] In a preferred embodiment, both limiting blocks are engaged with the limiting gear, and a return spring is fixedly installed on the front side of both limiting blocks, while the other end of each return spring is fixedly installed on the rear side of the support member.

[0018] The technical effect of adopting the above-mentioned further solution is that the return spring can be compressed by the limit block, causing it to retract.

[0019] In a preferred embodiment, the base has a second sliding groove on both sides of its top, and the bottom sides of the two support members are slidably connected to the inner surfaces of the two second sliding grooves. Bolts are fixedly installed on both sides of the two support members.

[0020] The technical effect of adopting the above-mentioned further solution is that it allows the support to slide through the second groove.

[0021] In a preferred embodiment, all four bolts are slidably connected inside the base, and nuts are threaded onto the outer surfaces of all four bolts. The opposite sides of the four nuts are movably connected to the outer side of the base.

[0022] The technical effect of adopting the above-mentioned further solution is that the nut can be rotated so that its inner side can fit against the outer surface of the base to fix the position of the support 108.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] This invention, through the design of the forward-rotating lead screw and the clamping plate body structure, not only allows personnel to adjust the height of the clamping plate body to accommodate sheet metal parts of different thicknesses, ensuring stability during clamping and avoiding excessively tight or loose clamping, thereby guaranteeing processing quality and improving the versatility of the equipment, but also effectively prevents the rotating rod from being misoperated when rotation is not needed, thus affecting the clamping effect. This solves the problem in the prior art that it is impossible to adjust according to the thickness of different sheet metal parts, and the clamping force and contact surface may not be accurately matched when clamping sheet metal parts of different thicknesses.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1, please refer to Figure 1-4 This utility model provides a technical solution: a sheet metal cutting clamp fixing structure for a freezer casing, including a base 1, a sheet metal part 101 on the top of the base 1, and support members 102 on both sides of the top of the base 1. It also includes: two rotating rods 103, each movably embedded in the rear side of the support member 102; a forward rotating screw 104 fixedly installed on the front side of each of the two rotating rods 103; two reverse rotating screws 105, each fixedly installed on the front side of the forward rotating screw 104; the outer surface of the front side of each of the two reverse rotating screws 105 movably embedded in the front side of the support member 102; and sliders 106 threadedly connected to the outer surfaces of the two forward rotating screws 104 and the two reverse rotating screws 105; two first sliding grooves 107, each formed on the top side of the inner wall of the support member 102; and four sliders 106 divided into two groups of two, with the top outer surfaces of the two groups of sliders 106 slidably connected to the first sliding grooves. On the inner surface of the groove 107, support rods 108 are movably connected to both sides of the four sliders 106. The other ends of the eight support rods 108 are movably connected to hinges 109. The eight hinges 109 are divided into two groups of four. The bottom of the two groups of hinges 109 is fixedly installed with clamping plate bodies 110. Limiting grooves 111 are opened on both sides of the inner wall of the two support members 102. The two sides of the clamping plate bodies 110 are slidably connected to the inner surface of the limiting grooves 111. Rubber pads 112 are provided at the bottom of the two clamping plate bodies 110. Limiting gears 113 are fixedly sleeved on the outer surface of the two rotating rods 103. Connecting columns 115 are fixedly installed on the rear side of the two support members 102. Limiting blocks 116 are slidably connected to the outer surface of the two connecting columns 115. Teeth are provided on the top of the two limiting blocks 116. Crank handles 114 are fixedly installed on the rear side of the two rotating rods 103.

[0033] In this embodiment, the operator can first place the sheet metal part 101 on top of the base 1, so that the sheet metal part 101 is located inside the support member 102. Then, push the limiting block 116 forward so that it can slide forward through the connecting column 115 and squeeze the return spring 117 to retract it, thereby allowing the limiting block 116 to disengage from the limiting gear 113 and release the lock on the rotating rod 103. Then, the operator can turn the crank handle 114 to transmit the rotation rod 103 to the forward rotation screw 104, and the forward rotation screw 104 to the reverse rotation screw 105. When the forward rotation screw 104 and the reverse rotation screw 105 rotate, they can drive the slider 106 to slide in opposite directions through the first slide groove 107. When the slider 106 slides, it can push the support rod 108, so that it can be flipped through the hinge 109. When rotating, the hinge 109 can push the clamping plate body 110 downward, allowing the clamping plate body 110 to slide downward through the limiting groove 111. As the clamping plate body 110 descends, it can drive the rubber pad 112 to move synchronously, allowing the rubber pad 112 to adhere to the top of the sheet metal part 101 for clamping and fixing. Through the structure of the forward rotation screw 104 and the clamping plate body 110, the operator can adjust the height of the clamping plate body 110 to accommodate sheet metal parts 101 of different thicknesses, ensuring stability during clamping and avoiding clamping that is too tight or too loose, thereby ensuring processing quality and improving the versatility of the equipment. At the same time, the locking function of the limiting block 116 and the limiting gear 113 can effectively prevent the rotating rod 103 from being misoperated when it is not needed, thus affecting the clamping effect.

[0034] Example 2, as Figure 1-4 As shown, both limiting blocks 116 are engaged with limiting gears 113. Both limiting blocks 116 are fixedly mounted with return springs 117 on their front sides. The other ends of both return springs 117 are fixedly mounted on the rear side of the support member 102. The top two sides of the base 1 are provided with second sliding grooves 2. The bottom two sides of the two support members 102 are slidably connected to the inner surfaces of the two second sliding grooves 2. Both sides of the two support members 102 are fixedly mounted with bolts 201. The four bolts 201 are slidably connected to the inside of the base 1. The outer surfaces of the four bolts 201 are threaded with nuts 202. The opposite sides of the four nuts 202 are movably connected to the outside of the base 1.

[0035] In this embodiment, the operator can first push the support member 102 so that it can slide on the inner surface of the second slide groove 2. The support member 102 then drives the bolt 201 to slide inside the base 1 to adjust the position of the support member 102. After the position of the support member 102 is adjusted, the operator can rotate the nut 202 so that its inner side can fit against the outer surface of the base 1 to fix the position of the support member 102. Through the structure of the second slide groove 2 and the nut 202, the operator can easily adjust the position of the support member 102 to adapt to different usage needs, further improving the versatility of the equipment. At the same time, the operator only needs to rotate the nut 202 to make its inner side fit tightly against the outer surface of the base 1 to fix the position of the support member 102, without complicated tools or operating steps, greatly reducing the cumbersomeness of the operator's operation.

[0036] Working principle: In use, the operator first places the sheet metal part 101 on top of the base 1, positioning it inside the support 102. Then, the operator pushes the limiting block 116 forward, allowing it to slide forward via the connecting column 115, and compresses the return spring 117 to retract it. This causes the limiting block 116 to disengage from the limiting gear 113, releasing the lock on the rotating rod 103. The operator then turns the crank handle 114, which transmits power from the rotating rod 103 to the forward screw 104, which in turn transmits power from the forward screw 104 to the reverse screw 105. When the forward and reverse screws 104 and 105 rotate, they drive the slider 106 to slide in opposite directions through the first groove 107. As the slider 106 slides, it pushes the support rod 108, causing it to flip via the hinge 109. During the flipping process, the hinge 109 can push the clamping plate body 110 downwards, allowing it to slide downwards through the limiting groove 111. As the clamping plate body 110 descends, it can drive the rubber pad 112 to move synchronously, allowing the rubber pad 112 to adhere to the top of the sheet metal part 101 for clamping and fixing. The design of the forward rotation screw 104 and the clamping plate body 110 structure not only allows personnel to adjust the height of the clamping plate body 110 to accommodate sheet metal parts 101 of different thicknesses, ensuring stability during clamping and avoiding clamping that is too tight or too loose, thus ensuring processing quality and improving the versatility of the equipment, but also effectively prevents the rotating rod 103 from being misoperated when it is not needed, thus affecting the clamping effect through the locking function of the limiting block 116 and the limiting gear 113. In use, the operator can first push the support member 102 so that it can slide on the inner surface of the second slide groove 2. The support member 102 then drives the bolt 201 to slide inside the base 1 to adjust the position of the support member 102. After the position of the support member 102 is adjusted, the operator can rotate the nut 202 so that its inner side fits against the outer surface of the base 1 to fix the position of the support member 102. Through the structure of the second slide groove 2 and the nut 202, the operator can easily adjust the position of the support member 102 to adapt to different usage needs, further improving the versatility of the equipment. At the same time, the operator only needs to rotate the nut 202 to make its inner side fit tightly against the outer surface of the base 1 to fix the position of the support member 102, without complicated tools or operating steps, greatly reducing the cumbersomeness of the operator's operation.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present 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 the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
