Description

TECHNICAL FIELD

[0001] The utility model relates to the field of mechanical tightening, especially to adjustable two-grasp capping clamp and tightening equipment. BACKGROUND

[0002] In the existing daily chemical factory automatic capping equipment, the capping clamp of the two-grasp or three-grasp type is used, the clamp needs to be customized according to the size of the product cap, one end of the clamp is connected to the cap main cylinder of the equipment, and the other end is attached to the cap, which is in the shape of a horn.

[0003] However, the following disadvantages exist: 1. The clamp is opened in the shape of a downward horn, and the contact surface is small with an angle between the clamp and the cap, the friction is low during the tightening process, and the cap is easily damaged or not tightened; 2. The size of the clamp after opening cannot be adjusted, and the same size clamp needs to be made for different size caps, which increases the cost of opening the clamp and is not conducive to the management of numerous clamps in the workshop; 3. There are multiple screws on the clamp, and it takes about 15 minutes to replace the clamp when switching products, which wastes manpower and material resources and increases production costs, resulting in a decrease in enterprise profits. SUMMARY

[0004] The utility model aims to overcome the above-mentioned defects in the prior art and provides a two-grasp capping clamp and a tightening equipment.

[0005] The utility model can achieve the purpose through the following technical solutions:

[0006] One of the technical solutions of the utility model is to provide a two-grasp capping clamp, which comprises two clamping parts arranged vertically and in parallel and used for clamping the clamped object, an upper clamping rail plate vertically arranged on the top of the clamping part and slidably connected with the clamping part, so that the two clamping parts can be relatively close or far apart along the length direction of the upper clamping rail plate.

[0007] A protruding part is arranged on the bottom of the side wall of the clamping part in contact with the clamped object, and a scale for assisting observation of the distance between the two clamping parts is further arranged on the upper clamping rail plate.

[0008] In some specific embodiments, a first groove is arranged on the side wall of the clamping part in contact with the clamped object for placing a buffer along the length direction.

[0009] In some specific embodiments, an elastic member is arranged in the first groove.

[0010] In some specific embodiments, a clamping groove is arranged on the top of the clamping part, and a rail for embedding the clamping groove and slidably connected with the clamping groove is arranged on the bottom of the upper clamping rail plate.

[0011] In some embodiments, the card slot is narrow at the top and wide at the bottom.

[0012] In some embodiments, the top side wall of the clamping part is provided with a first screw hole position penetrating the card slot, so that the screw passes through the first screw hole position and abuts against the rail located in the card slot to fix the position of the clamping part.

[0013] In some embodiments, the top of the clamping part is also provided with a second groove for observing the position of the screw, which is located between the first screw hole position and the card slot.

[0014] In some embodiments, the top side wall of the clamping part is also provided with a positioning point for indicating the scale on the ruler.

[0015] In some embodiments, the top of the upper clamping rail plate is provided with a plurality of second screw hole positions for connecting with the driving mechanism.

[0016] The second technical scheme of the utility model provides a tightening device, which comprises the two-grasp cap clamp of any one of the above technical schemes, and a driving mechanism connected with the upper clamping rail plate and used for driving the upper clamping rail plate to move closer or farther away.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] (1) The two-grasp cap clamp of the utility model is perpendicular to the plane where the bottle cap is located when clamping the to-be-clamped object such as a bottle cap, which reduces the included angle with the bonding surface of the bottle cap, increases the contact surface and the friction force. Compared with the horn-shaped clamp, the contact surface of the clamp of the application is larger, which changes from a point to a surface, and the fixing is more stable, effectively reducing the downtime caused by loose clamp.

[0019] (2) The two-grasp cap clamp of the utility model can be used for clamping both conventional and special-shaped to-be-clamped objects. The protruding part provided at the bottom of the side wall of the clamping part in contact with the special-shaped bottle cap (especially the bottle cap with a wide top and a narrow bottom) can effectively increase the contact surface between the clamping part and the special-shaped bottle cap, thereby increasing the friction force and realizing faster and more stable tightening of the bottle cap.

[0020] (3) The clamping part of the two-grasp cap clamp of the utility model can slide along the upper clamping rail plate, and the distance between the two clamping parts can be adjusted arbitrarily to adapt to to-be-clamped objects of different sizes and reduce mold opening costs. The ruler on the upper clamping rail plate can also intuitively provide the distance between the two clamping parts, making it easy to find the center point when switching and reducing switching time.

[0021] (4) The two-grasp screw cap clamp only locks the clamping parts on both sides and the upper clamping track plate through two screws respectively, the production change time is reduced by at least 80%, the clamp time is greatly shortened when the product is changed, and the production change is facilitated.

[0022] (5) The two-grasp screw cap clamp is improved by 3-5 times, one set of clamp can be used for at least three products, the production change time is reduced by 80%, and the damage of the bottle cap is eliminated by more than 90%. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0032] The utility model will be described in detail in combination with the drawings and specific embodiments. The embodiment is implemented on the premise of the technical scheme of the utility model, and detailed implementation mode and specific operation process are given, but the protection scope of the utility model is not limited to the following examples.

[0033] It should be noted that: similar signs and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0034] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] In the following embodiments, unless otherwise specified, the functional components or structures are conventional components or structures used in the art to achieve the corresponding functions.

[0036] Example 1:

[0037] like Figures 1-7 As shown, an adjustable two-grip screw cap clamp includes two clamping parts 1 arranged vertically and parallel to each other for clamping the object to be clamped, and an upper clamping track plate 10 respectively arranged vertically on the top of the clamping parts 1 and slidably connected to the clamping parts 1, so that the two clamping parts 1 can move closer or further apart relative to each other along the length direction of the upper clamping track plate 10.

[0038] The bottom of the side wall of the clamping part 1 that contacts the object to be clamped is provided with a protrusion 2, and the upper clamping track plate 10 is also provided with a scale 11 for assisting in observing the distance between the two clamping parts 1.

[0039] In this technical solution, the top of the clamping part 1 is perpendicular to the upper clamping track plate 10, and the bottom is also perpendicular to the object to be clamped, such as a bottle cap. The protrusion 2 on the clamping part 1 makes the space between the two clamping parts 1 wider at the top and narrower at the bottom, effectively increasing the contact area between the clamping part 1 and the object to be clamped, especially irregularly shaped objects (generally wider at the top and narrower at the bottom), increasing friction, and thus increasing clamping force. This allows for clamping both conventional and irregularly shaped objects. By sliding the clamping part 1 on the upper clamping track plate 10 to adjust the distance between the two clamping parts 1, it can be applied to objects of more sizes, greatly improving adaptability.

[0040] like Figure 2 As shown, the side wall of the clamping part 1 that contacts the object to be clamped is provided with a first groove 4 for being arranged along its length. An elastic element, such as a silicone pad, is provided in the first groove 4 to increase the friction between the side wall of the clamping part 1 and the object to be clamped through elasticity.

[0041] like Figure 1 , 2 As shown in Figures 7 and 8, the top of the clamping part 1 is provided with a slot 6, and the bottom of the upper clamping track plate 10 is provided with a track 8 for embedding in the slot 6 and slidingly connecting with the slot 6, so as to facilitate the adjustment of the distance between the clamping parts 1. Preferably, the slot 6 is narrow at the top and wide at the bottom, such as a dovetail groove with a trapezoidal cross section, which further strengthens the interlocking relationship between the two and prevents separation during sliding.

[0042] like Figure 3As shown, the top side wall of the clamping part 1 is provided with a first screw hole 7 through the clamping groove 6, so that the screw passes through the first screw hole 7 to abut against the track 8 in the clamping groove 6 to fix the position of the clamping part 1. The technical solution only locks the clamping part 1 on both sides and the upper clamping track plate 10 by two screws, greatly reducing the time for replacing the clamp when switching products.

[0043] As shown in the drawings, Figure 2 As shown, the top of the clamping part 1 is also provided with a second groove 5 for observing the position of the screw, which is located between the first screw hole 7 and the clamping groove 6. When the screw passes through the first screw hole 7, the position of the screw can be observed through the gap of the second groove 5.

[0044] As shown in the drawings, Figure 3 As shown, the top side wall of the clamping part 1 is provided with a first screw hole 7 through the clamping groove 6, so that the screw passes through the first screw hole 7 to abut against the track 8 in the clamping groove 6 to fix the position of the clamping part 1. The technical solution only locks the clamping part 1 on both sides and the upper clamping track plate 10 by two screws, greatly reducing the time for replacing the clamp when switching products.

[0045] As shown in the drawings, Figure 6 As shown, the top of the clamping part 1 is also provided with a second groove 5 for observing the position of the screw, which is located between the first screw hole 7 and the clamping groove 6. When the screw passes through the first screw hole 7, the position of the screw can be observed through the gap of the second groove 5.

[0046] Embodiment 2:

[0047] The embodiment provides a tightening device, as shown in the drawings, comprising two cap grabbing clamps as described in embodiment 1, and a driving mechanism 9 connected with the upper clamping track plate 10 and used for driving the upper clamping track plate 10 to approach or move away. Figure 1

[0048] Illustratively, the driving mechanism 9 is provided with a cylinder, a motor and the like, which is connected with the upper clamping track plate 10 to drive the upper clamping track plate 10 to clamp the object to be clamped with the clamping part 1 below the upper clamping track plate 10, and the driving mechanism 9 rotates to tighten the bottle cap.

[0049] The above description of the embodiments is for the convenience of those skilled in the art to understand and use the utility model. Those skilled in the art can easily make various modifications to these embodiments, and apply the general principles described herein to other embodiments without creative labor. Therefore, the utility model is not limited to the above embodiments, and the improvements and modifications made by those skilled in the art without departing from the scope of the utility model should be within the protection scope of the utility model.​
