Description

Technical Field

[0001] This utility model belongs to the field of clamp anti-fall technology, specifically relating to a clamping product anti-fall mechanism. Background Technology

[0002] Fixtures, as key process equipment in machining, heat treatment, and assembly processes, directly affect machining accuracy, production efficiency, and manufacturing costs. According to statistics from the International Production Research Association, over 85% of workpiece production in modern manufacturing relies on fixtures for positioning and clamping. Especially in multi-variety, small-batch production models, the flexibility and precision of fixtures become core factors restricting production efficiency. Traditional fixture designs often employ fixed locating pin structures, achieving workpiece positioning through the "one-face, two-pin" principle (a flat plane restricting 3 degrees of freedom, a cylindrical pin restricting 2 degrees of freedom, and a diamond-shaped pin restricting 1 degree of freedom).

[0003] However, such designs have significant limitations when dealing with complex workpieces, high-precision machining, or flexible manufacturing requirements. The center of gravity of some complex workpieces may shift, causing them to tilt when placed on fixed supports, which reduces the accuracy of subsequent machining. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a clamping and anti-fall mechanism for products. The workpiece is placed on a fixed support mechanism, and the movable support mechanism is installed in the corresponding threaded hole according to the actual offset of the workpiece's center of gravity, so that the workpiece is in a horizontal state. The workpiece is fixed by the fixing mechanism, which facilitates subsequent processing. This solves the problem that the center of gravity of some complex workpieces may be offset, and when placed on the fixed support, they will be skewed, which will reduce the accuracy of subsequent processing.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a clamping product anti-fall mechanism, including a base, a fixed support mechanism is provided in the middle of the base according to the actual situation of the workpiece, a number of threaded holes are opened on both sides of the middle of the base, and a movable support mechanism for keeping the workpiece in a horizontal state when the workpiece is placed on the fixed support mechanism is threaded inside the threaded holes, and a fixing mechanism for clamping and fixing the workpiece is provided on the side of the fixed support mechanism.

[0006] Preferably, the movable support mechanism includes a support bolt threadedly connected to a threaded hole, and a fixing nut threadedly connected to the support bolt to fix its height.

[0007] Preferably, the support bolt is an internal hex bolt, and the fixing nut is a hex nut.

[0008] Preferably, the fixed support mechanism includes a circular hole support and a platform support; the circular hole support is used to support and position the hole on the workpiece; the platform support is used to support and position the flat step surface on the workpiece.

[0009] Preferably, the circular hole support includes a circular fixing seat disposed on the base, and the top of the circular fixing seat is provided with a positioning pin that matches the hole in the workpiece.

[0010] Preferably, the platform support includes a square fixing seat mounted on the base, and the top of the square fixing seat is provided with a placement groove that matches the stepped surface of the workpiece.

[0011] Preferably, the fixing mechanism includes a cylinder mounted on the base, and the output end of the cylinder is connected to a pressing block.

[0012] Preferably, the base has mounting holes at both ends for fixing it to the processing equipment.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the workpiece is placed on the fixed support mechanism, and the movable support mechanism is installed in the corresponding threaded hole according to the actual offset of the workpiece's center of gravity, so that the workpiece is in a horizontal state. The workpiece is fixed by the fixed mechanism, which facilitates subsequent processing and effectively avoids safety accidents and equipment damage caused by the workpiece falling. At the same time, it can also ensure processing accuracy and product quality.

[0017] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0018] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a clamping product anti-fall mechanism includes a base 1, a fixed support mechanism 2 is provided in the middle of the base 1 according to the actual situation of the workpiece, and several threaded holes 3 are opened on both sides of the middle of the base 1. The threaded holes 3 are threaded with movable support mechanisms 4 for keeping the workpiece in a horizontal state when the workpiece is placed on the fixed support mechanism 2. A fixing mechanism 5 for clamping and fixing the workpiece is provided on the side of the fixed support mechanism 2.

[0019] This utility model proposes a clamping and anti-fall mechanism for products. The base 1 serves as the basic frame of the entire mechanism, providing a stable mounting platform for other parts. A fixed support mechanism 2 is positioned in the middle of the base 1, its shape and structure designed according to the actual condition of the workpiece. It provides a fixed support point or surface for the workpiece, ensuring a stable foundation during clamping. Several threaded holes 3 are located on both sides of the middle of the base 1. These threaded holes 3 provide mounting positions for the movable support mechanism 4, allowing for convenient installation and adjustment via threaded connections.

[0020] The movable support mechanism 4 is internally threaded into the threaded hole 3. When the workpiece is placed on the fixed support mechanism 2, the height or position of the movable support mechanism 4 is adjusted to ensure the workpiece is horizontal. This ensures the stability and accuracy of the workpiece during clamping and prevents problems such as insecure clamping or machining errors caused by workpiece tilting.

[0021] The fixing mechanism 5 is located next to the fixing support mechanism 2. It clamps and fixes the workpiece placed on the fixing support mechanism 2 and adjusted to a horizontal state, ensuring that the workpiece will not move or fall during processing, thus ensuring smooth processing and processing quality.

[0022] First, based on the shape and size of the workpiece, the fixed support mechanism 2 is placed in a suitable position in the middle of the base 1 to meet the workpiece's support requirements. Using the threaded holes 3 on both sides of the middle of the base 1, the movable support mechanism 4 is installed in a suitable position, and its height is adjusted by rotating it to ensure the workpiece is level when placed on the fixed support mechanism 2. This step is crucial because the levelness of the workpiece directly affects the subsequent clamping stability and machining accuracy.

[0023] The workpiece is placed on the fixed support mechanism 2 and kept horizontal by the support of the movable support mechanism 4. Then, the fixing mechanism 5 is operated to clamp and secure the workpiece. The fixing mechanism 5 can use mechanical clamping, hydraulic clamping, or other suitable clamping methods to ensure that the workpiece will not shift or loosen during processing. After the workpiece is securely clamped, subsequent processing operations can be performed. Because the workpiece is stably fixed on the anti-fall mechanism, safety accidents and equipment damage caused by workpiece falling can be effectively avoided, while also ensuring processing accuracy and product quality.

[0024] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the movable support mechanism 4 includes a support bolt 41 that is threadedly connected to the threaded hole 3, and a fixing nut 42 that fixes its height is threadedly connected to the support bolt 41.

[0025] Specifically, the support bolt 41 is threadedly connected to the threaded hole 3 on the base 1. The support bolt 41 is mounted on the base 1 and can be adjusted up and down within the threaded hole 3 according to actual needs, thereby changing its vertical height position.

[0026] The fixing nut 42 is installed on the support bolt 41 by means of a threaded connection. After the support bolt 41 is adjusted to a suitable height, its height is fixed to prevent the support bolt 41 from changing height due to external forces during subsequent operations, thereby ensuring the stability of the movable support mechanism 4 in supporting the workpiece.

[0027] The internal thread of the fixing nut 42 is tightly engaged with the external thread of the support bolt 41. By tightening the fixing nut 42, sufficient friction is generated between it and other relevant parts on the base 1 or the support bolt 41, thus fixing the support bolt 41 at the current height position.

[0028] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the support bolt 41 is an internal hex bolt, and the fixing nut 42 is a hex nut.

[0029] Specifically, the support bolt 41 (hex socket head cap screw) has a typical bolt shape, consisting of a shank and a head. The shank has external threads for threaded connection with the threaded hole 3 on the base 1. Rotation allows it to move up and down within the threaded hole 3, thus adjusting the height. The head is hex socket head cap screw, allowing for easy operation using an internal hex wrench inserted into the head's internal hex socket during installation and adjustment. Compared to external hex socket head cap screws, the internal hex design is more compact, facilitating operation even in limited spaces, and avoids the potential for interference with other components.

[0030] The fixing nut 42 (hexagonal nut) is hexagonal, making it easy to tighten and loosen using tools such as wrenches. The nut has internal threads that match the external threads of the support bolt 41, and it is connected to the support bolt 41 through threaded engagement.

[0031] Combination Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the fixed support mechanism 2 includes a circular hole support 21 and a platform support 22; the circular hole support 21 is used to support and position the holes on the workpiece; the platform support 22 is used to support and position the flat stepped surfaces on the workpiece.

[0032] Specifically, the round hole support 21 is installed in the middle of the base 1, and the position is determined according to the position of the hole on the workpiece to ensure that it can be accurately inserted into the hole of the workpiece to achieve support and positioning.

[0033] Platform support 22 and circular hole support 21 are arranged together on base 1 and installed reasonably according to the position of the workpiece plane step surface to ensure that they can provide stable and reliable support for the workpiece plane step surface.

[0034] Through the coordinated work of the circular hole support 21 and the platform support 22, the fixed support mechanism 2 can provide stable and accurate support and positioning for the workpiece, ensuring the smooth progress of subsequent processing operations and the stable and reliable processing quality.

[0035] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the circular hole support 21 includes a circular fixed seat 211 disposed on the base 1, and a positioning pin 212 matching the workpiece hole is disposed at the top of the circular fixed seat 211.

[0036] Specifically, the circular fixing seat 211 is fixedly installed on the base 1, and the position is precisely determined according to the position of the hole on the workpiece to ensure that the positioning pin 212 can be accurately inserted into the workpiece hole to achieve support and positioning of the workpiece. The positioning pin 212 is vertically set at the top of the circular fixing seat 211, and is usually installed by interference fit, threaded connection or other methods.

[0037] When the locating pin 212 is inserted into the workpiece hole, the cylindrical surface of the locating pin 212 is in close contact with the inner wall of the workpiece hole, restricting the workpiece's movement and rotation in the horizontal direction. The locating pin 212 prevents the workpiece from translating in the direction perpendicular to the axis of the locating pin 212, as well as rotating about the axis of the locating pin 212, thereby determining the accurate position of the workpiece in the plane.

[0038] Combination Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the platform support 22 includes a square fixing seat 221 disposed on the base 1, and the top of the square fixing seat 221 is provided with a placement groove 222 that matches the step surface of the workpiece plane.

[0039] Specifically, the square mounting base 221 is fixedly installed on the base 1, and its position is determined according to the step surface of the workpiece. Installation methods can include bolting or welding. Bolting facilitates the disassembly and replacement of the square mounting base 221, making maintenance and adjustment easier; welding provides a more secure connection between the square mounting base 221 and the base 1, suitable for applications requiring high stability. The placement slot 222 is vertically positioned at the top of the square mounting base 221, and its location is determined according to the overall layout and positioning requirements of the workpiece to ensure that the workpiece is in the correct position after placement, meeting the needs of subsequent processing or assembly.

[0040] When a workpiece with a flat, stepped surface needs to be placed on the platform support 22, the operator aligns the flat, stepped surface of the workpiece with the placement groove 222 and slowly lowers the workpiece. Since the placement groove 222 is located at the top of the square fixing base 221, which is stably mounted on the base 1, the placement groove 222 provides a vertically upward supporting force for the workpiece. As the workpiece falls, the flat, stepped surface gradually sinks into the placement groove 222 until the workpiece is completely placed on the platform support 22. At this point, the square fixing base 221 bears part of the workpiece's weight and transfers it to the base 1, ensuring stable vertical support for the workpiece.

[0041] After the workpiece's flat stepped surface falls into the placement groove 222, the inner wall of the groove 222 is in close contact with the side of the workpiece's flat stepped surface, restricting the workpiece's horizontal movement. The two side walls of the placement groove 222 prevent the workpiece from translating in two mutually perpendicular horizontal directions, thus determining the workpiece's accurate position in the plane. Simultaneously, the good fit between the bottom surface of the placement groove 222 and the workpiece's flat stepped surface provides a stable support reference for the workpiece, further ensuring positioning accuracy. Through this support and positioning function, the platform support 22 enables the workpiece to maintain a stable position during processing or assembly, ensuring product quality and production efficiency.

[0042] Combination Figure 1 , Figure 2 and Figure 3 As shown, the fixing mechanism 5 includes a cylinder 51 mounted on the base 1, and the output end of the cylinder 51 is connected to a pressing block 52.

[0043] Specifically, the fixing mechanism 5 mainly consists of two parts: a cylinder 51 and a lower pressure block 52. These two parts are installed together on the base 1 to fix the workpiece. The cylinder 51 is mounted on the base 1, typically using bolts. Precise positioning and installation ensure that the axis of the cylinder 51 is aligned with the direction of movement of the lower pressure block 52, guaranteeing the accuracy and stability of the pressing action. The lower pressure block 52 is connected to the output end (piston rod) of the cylinder 51 using bolts, pins, or other means. It must be able to transmit the downward pressure generated by the cylinder 51 while also being easy to disassemble and replace, allowing for the selection of a suitable lower pressure block 52 for different workpieces.

[0044] Combination Figure 1 , Figure 2 and Figure 3 As shown, the base 1 has mounting holes 6 at both ends for fixing it to the processing equipment.

[0045] Specifically, mounting holes 6 are located at both ends of the base 1 to ensure more even force distribution during installation and improve installation stability. A certain number of mounting holes 6 are provided at each end of the length direction of the base 1. The number depends on the size of the base 1 and the load-bearing requirements, and is generally 2 to 4 or even more.

[0046] When it is necessary to fix the base 1 on the processing equipment, first place the base 1 in the designated installation position on the processing equipment, and adjust the position and level of the base 1 to ensure that the base 1 fits accurately with other parts of the processing equipment. Then, use appropriate bolts or screws to pass them through the mounting holes 6 at both ends of the base 1 and screw them into the pre-set holes on the processing equipment.

[0047] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
