Description

Technical Field

[0001] The present invention relates to the technical field of power tools, and in particular to an electric clamping mechanism. Background Art

[0002] The shell-and-tube heat exchanger is composed of concentric inner tube and outer tube. The hot and cold fluids flow in the annular gap of the inner tube and outer tube respectively while transferring heat. It is pressure-resistant and shock-resistant, not easy to deform, dirt-resistant and scale-resistant, not easy to clog, smooth oil return, high safety, good processability, not easy to leak, flexible structure, convenient layout, low price, cost saving, and is particularly suitable for heat pump systems. At the same time, the gap between the steel pipe and the copper pipe is evenly divided, which is conducive to maintaining good oil return characteristics when used as an evaporator. The materials of the inner and outer pipes are copper, stainless steel, etc., which can be widely used in refrigeration and air-conditioning industries such as chillers, air-cooled / water-cooled heat pump units, water source / ground source heat pump units, heat recovery units, and heat pump water heaters.

[0003] Since the shell-and-tube heat exchanger needs to be bent into oval, square and other shapes using a pipe bender during processing, in order to ensure the height requirements of the product, it is necessary to use a bench vise to clamp the product to adjust the gap of the product, and then use two-way welding to weld and fix the gap to meet the customer's size requirements for the product.

[0004] The bench vise is composed of a pliers body, a base, a guide nut, a lead screw, a jaw body, etc. The movable pliers body slides with the guide rail of the fixed pliers body through the guide rail. The lead screw is installed on the movable pliers body and can rotate but cannot move axially. It cooperates with the lead screw nut installed in the fixed pliers body. When the handle is shaken to rotate the lead screw, the movable pliers body can be driven to move axially relative to the fixed pliers body to clamp or loosen.

[0005] Because the screw of the bench vise will wear out after being used in an environment with welding slag for a long time, the entire bench vise will be scrapped and cannot be used normally. Frequent replacement of the bench vise also brings losses to the company. Summary of the invention

[0006] In view of this, the present invention provides an electric clamping mechanism to solve the problem that after the bench vise is used in an environment with welding slag for a long time, the screw will be worn out, causing the entire bench vise to be scrapped and unable to be used normally.

[0067] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0069] Example

[0070] The traditional bench vise is composed of a pliers body, a base, a guide nut, a lead screw, a jaw body, etc. The movable pliers body slides with the guide rail of the fixed pliers body through a guide rail. The lead screw is installed on the movable pliers body and can rotate but cannot move axially. It cooperates with the lead screw nut installed in the fixed pliers body. When the handle is shaken to rotate the lead screw, the movable pliers body can be driven to move axially relative to the fixed pliers body to clamp or loosen.

[0071] Since the bench vise needs to be clamped and opened manually by hand during use, it is also necessary to adjust the stroke to meet the clamping requirements when the height difference of the product is large. When employees are working, repeated operations can easily cause physical exhaustion and reduced efficiency. In addition, it is difficult to reset the bench vise after exceeding the maximum stroke, and its own weight is too heavy, which increases the fatigue of employees and seriously affects the production capacity of the product. In addition, the bench vise is made of cast iron, which is easy to cause clamping injuries to products with soft copper tubes, resulting in quality losses.

[0072] At the same time, due to structural defects, the screw of the bench vise will wear out after long-term use in an environment with welding slag, causing the entire bench vise to be scrapped and unable to be used normally. Frequent replacement of bench vises also caused losses to the company. In addition, the middle part of the bench vise is narrow, and when large products are placed in it, it cannot be effectively supported and requires manual support, which poses a safety hazard of product falling.

[0073] In this embodiment, the electric clamping mechanism includes a fixed base plate 1, a protective cover 2, a transmission assembly 3, a fixed clamping member 4 and a movable clamping member 5. Figure 1 and Figure 2As shown, the protective cover 2 is covered on the fixed base plate 1, and a transmission cavity is formed between the protective cover 2 and the fixed base plate 1; the transmission assembly 3 is connected to the fixed base plate 1 and placed inside the transmission cavity, and the transmission assembly 3 is suitable for connecting with the driving member 6; the fixed clamping member 4 is connected to the fixed base plate 1 and is located outside the protective cover 2, and the fixed clamping part of the fixed clamping member 4 protrudes from the upper surface of the protective cover 2; the movable clamping member 5 includes a transmission part that is located inside the transmission cavity and connected to the transmission assembly 3, a connecting part that is connected to the transmission part and is penetrated in the through grooves on both sides of the protective cover 2, and a movable clamping part that is connected to the connecting part and is located on the upper side of the protective cover 2; wherein a clamping space is formed between the movable clamping part and the fixed clamping part, and the movable clamping member 5 is configured to slide in the through grooves on both sides of the protective cover 2 under the drive of the transmission assembly 3 to clamp or release the part to be clamped in the clamping space.

[0074] In this embodiment, a protective cover 2 is provided on the upper side of the fixed base plate 1 to form a transmission cavity between the upper side of the fixed base plate 1 and the protective cover 2. The transmission component 3 is placed inside the transmission cavity, thereby preventing welding slag and other debris from falling into the transmission component 3 and affecting the use of the transmission component 3.

More specifically, the fixed clamping member 4 is fixed to the end of the fixed base plate 1, and the fixed clamping portion of the fixed clamping member 4 protrudes from the upper surface of the protective cover 2. By setting the fixed clamping portion of the fixed clamping member 4 to protrude from the upper surface of the protective cover 2, it is possible to avoid the existence of the protective cover 2 affecting the clamping of the fixed clamping member 4 on the clamped member. The movable clamping member 5 is provided to include a transmission portion, a connecting portion and a movable clamping portion. The transmission portion is located inside the transmission cavity and is connected to the transmission assembly 3. The connecting portion is connected to the transmission portion and is passed through the through grooves on both sides of the protective cover 2. The movable clamping portion is connected to the connecting portion and is located on the upper side of the protective cover 2. When in use, the transmission assembly 3 drives the transmission portion connected thereto to move, as shown in FIG. Figure 2 As shown, a long strip-shaped through groove is opened on the side of the protective cover 2, and the connecting part is movably arranged inside the through groove. When the transmission component 3 drives the transmission part to move, the connecting part is driven by the transmission part to move inside the through groove. The movable clamping part is located on the upper side of the protective cover 2, and the fixed clamping part of the fixed clamping part 4 protrudes from the upper surface of the protective cover 2. Therefore, a clamping space is formed between the movable clamping part and the fixed clamping part.

The middle plate 52 is connected to the two ends of the transmission plate 51 extending out of the transmission cavity, and the middle plate 52 and the middle part of the transmission plate 51 form a through slot, and the upper cover is penetrated in the through slot. The side plate 53 of the movable clamp is connected to the middle plate 52, the clamp is connected to the side plate 53 of the movable clamp, and the clamp and the side plate 53 of the movable clamp constitute the movable clamp.

[0080] Specifically, the splint includes a steel splint 54 and an aluminum splint 55. The steel splint 54 is connected to the movable clamping member side plate 53, and the aluminum splint 55 is fixed to the steel splint 54 by magnetic attraction. The aluminum splint 55 can be easily installed and disassembled to meet the clamping work of workpieces of different materials.

[0082] In this embodiment, if Figure 3 and Figure 4 As shown, the bottom of the transmission plate 51 is divided into three parts, which are three grooves. Figure 3 As shown, there are two guide assemblies 8 and one transmission assembly 3, and the two guide assemblies 8 are arranged on both sides of the transmission assembly 3. In the transmission plate 51, the middle groove is used to connect with the transmission assembly 3, and the side groove is used to connect with the guide assembly 8. The side of the transmission plate 51 is bent upward and connected to the middle plate 52, so that a through groove is formed on the top of the middle plate 52 and the transmission plate 51.

[0083] In this embodiment, if Figure 5 As shown, the fixed clamp 4 includes a fixed clamp side plate 41, a fixed clamp reinforcement rib 42 and a clamping plate, the bottom of the fixed clamp side plate 41 is fixed to the fixed base plate 1, the top of the fixed clamp side plate 41 is fixed to the clamping plate, the side of the fixed clamp reinforcement rib 42 is fixed to the fixed clamp side plate 41, and the bottom of the fixed clamp side plate 41 is fixed to the fixed base plate 1. The clamping plate in the fixed clamp 4 has the same structure as the clamping plate in the movable clamp 5.

[0084] In this embodiment, the transmission assembly 3 includes a support 31, a screw rod 32, an adapter 33, a bearing seat 34, a fixing ring 35 and a coupling 36. The structure of the transmission assembly 3 is described in detail below.

[0085] like Figure 7 As shown, the support 31 is fixed to the fixed base plate 1 by screws, the bearing seat 34 is fixed to the support 31 by screws, the adapter 33 is installed on the screw rod 32, the screw rod 32 is fixed in the bearing seat 34, one end of the coupling 36 is sleeved on the screw rod 32, and the other end is connected to the driving member 6 through the fixing ring 35. Among them, the adapter 33 is connected to the transmission plate 51, and the screw rod 32 is driven by the driving member 6 to rotate around the axis of the screw rod 32, and drives the adapter 33 to move on the screw rod 32 along the axial direction of the screw rod 32.

[0086] In this embodiment, the screw rod 32 is a trapezoidal screw rod 32 and the adapter 33 is a nut. When the driving member 6 drives the screw rod 32 to rotate, the screw rod 32 can drive the adapter 33 to move axially along the screw rod 32, and then drive the movable clamping member 5 to move through the adapter 33.

[0087] In this embodiment, the guide assembly 8 includes a guide shaft 81, a bushing 82, a guide shaft support 83, a bushing bracket 84 and a bushing cover plate 85. The structure of the transmission assembly 3 is described in detail below.

[0089] The bushing bracket 84 is fixedly connected to the bottom of the transmission plate 51 of the movable clamping member 5 by screws. When the movable clamping member 5 is driven by the transmission assembly 3 to move, the bushing 82, the bushing bracket 84 and the bushing cover plate 85 will move together with the movable clamping member 5. At the same time, since the bushing 82 is slidably set on the guide shaft 81, the guide shaft 81 can limit the moving trajectory of the bushing 82, thereby limiting the moving trajectory of the movable clamping member 5 and achieving a guiding effect.
