[0002] At present, in the process of mechanical processing, the way parts are clamped and pressed directly affects the processing quality, processing efficiency and safe production. Among them, the most commonly used clamping method is ordinary pressure plate clamping. There are two commonly used pressure plates now, one is a set of step washers (triangular washers), and the other is various types of self-made simple pressure plates. Their main feature is relatively simple. They are generally composed of pressure plates and bolts, nuts and spacers. For details, please refer to the flange drilling fixture disclosed in Chinese patent publication number "CN203371274U", including a base, a sliding column, a drilling template, a spacer, a bushing, a core shaft, a locking nut and a pressure plate; a sliding column is provided at each end of the base; a slidable drilling template is provided on the two sliding columns; a circular hole is opened on the drilling template; the circular hole is the same size as the diameter of the workpiece

[0003] When clamping the workpiece, if there is no pad at the same height as the workpiece, some pads are overlapped until they are the same height as the workpiece. The disadvantage of this combination of pressure plates is that the thickness of the pressure plate and the height of the nut will increase during clamping, causing programmers to consider the extra height when compiling programs, so the tool needs to be extended when selected, and sometimes even an extension rod is used. This will affect the rigidity of the tool and make it easy for the tool to vibrate or break. This is more obvious when facing thin-walled parts. For this reason, a hidden clamping method is required to avoid lengthening the tool, while supporting the side of the product to prevent vibration. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-2 This is an embodiment of the utility model. Specifically, this embodiment discloses a workpiece side top clamping fixture, which includes a spindle flange 1. In this embodiment, the spindle flange 1 is a four-axis flange. A fixture fixing plate 2 is detachably connected to the front side of the spindle flange 1. The fixture fixing plate 2 is used to position and support a part sample 3.

[0022] In some preferred embodiments, the tooling fixing plate 2 in the present invention is fixed to the spindle flange 1 by means of positioning pins and bolts. This connection method is a conventional technical means for technicians in the relevant field and will not be described in detail here.

[0023] Wherein, a side top assembly 4 can be detachably provided on the front side of the tooling fixing plate 2, and the side top assembly 4 is used to abut and fix the side edge of the part sample 3;

[0024] The side top assembly 4 includes a guide portion 41 and a sliding portion 42 . An adjusting member 43 is disposed between the sliding portion 42 and the guide portion 41 . A clamping portion 44 is also disposed on the sliding portion 42 .

[0025] In some embodiments, the guide portion 41 in the utility model includes a fixed seat 411, and a wedge-shaped groove 412 is opened between the two side surfaces of the fixed seat 411, wherein a mounting hole 413 that passes through the fixed seat 411 is also opened in the wedge-shaped groove 412, and the mounting hole 413 is connected to the tooling fixing plate 2 through a fastener. Specifically, in the present embodiment, two mounting holes 413 are opened at intervals to ensure the installation stability of the fixed seat 411. In addition, the mounting hole 413 is set as a countersunk hole to avoid burying the end of the fastener in the upper end notch thereof, so as to avoid the problem that the upper end of the fastener protrudes and affects the sliding of the sliding portion 42. Technicians in the relevant field know that in the present embodiment, the fastener is preferably set as a hexagon socket bolt.

[0026] Furthermore, in this embodiment, the sliding portion 42 is a wedge-shaped block, and the wedge-shaped block is slidably connected in the wedge-shaped groove 412, wherein the clamping portion 44 is a convex ridge portion provided on the wedge-shaped block.

[0027] It should be noted that in the embodiment of the utility model, the clamping portion 44 and the sliding portion 42 are detachably connected, and the disassembly method can be achieved by connecting and fixing with bolts. Of course, in other embodiments, an insertion rod can be provided on the end face of the sliding portion 42, and the insertion rod is plugged into and penetrates the clamping portion 44, wherein a positioning glass bead is embedded on the outer side of the rear end of the insertion rod, and the positioning glass bead is used to limit the position, thereby improving the convenience of disassembly and assembly of the clamping portion 44.

[0028] In some embodiments, through holes 421 are formed through the two sides of the wedge block in the utility model, and the adjusting member 43 is an adjusting bolt penetrated through the through hole 421, wherein a threaded hole matching the adjusting bolt is provided on the tooling fixing plate 2.

[0029] That is to say, when working, the guide part 41 is first fixed on the tooling fixing plate 2, and then the sliding part 42 is installed. The sliding part 42 is driven and controlled by the adjusting member 43. When the adjusting member 43 is threadedly connected with the threaded hole on the tooling fixing plate 2, it will resist the movement of the sliding part 42, so that the clamping part 44 on the side of the sliding part 42 resists and presses the side of the part sample 3. The overall structure is simple, and the side top method achieves the purpose of fixing and shockproofing the part sample 3.

[0030] In some embodiments, the present invention further comprises a dummy cover assembly 5 , which is disposed on the front side of the part sample 3 and connected to the tooling fixing plate 2 .

[0031] On the basis of the above embodiment, the imitation cover assembly 5 in this embodiment includes a profiling cover plate 51 covering the front side of the part sample 3, and a first bolt 52 penetrating through the part sample 3 and connected to the tooling fixing plate 2 is provided on the end surface of the profiling cover plate 51;

[0032] A second bolt 53 is further installed on the tool fixing plate 2 , and a pressing plate 54 is arranged on the end surface of the second bolt 53 .

[0033] During operation, the tooling fixing plate 2 is first fixed on the spindle flange 1, and then the part sample 3 is placed on the specified position of the tooling fixing plate 2. Then, the contoured cover plate 51 is fixed on the tooling fixing plate 2 by using the first bolt 52, the pressure plate 54 and the second bolt 53. Finally, the side top assembly 4 is used to lock the side of the part sample 3 to complete the clamping and fixing.

[0034] In summary, the utility model adopts the lateral sliding mode of the wedge block to perform the contact positioning on the side of the part sample 3, and the hidden clamping avoids the lengthening of the tool, and can support the side of the product to prevent the tool from vibrating. Thereby improving the reliability of clamping, the position of the device can be adjusted according to the actual characteristics of the product, and at the same time, it also has a better effect for thin-walled products with relatively high clamping force requirements such as auxiliary support on the side of the workpiece. The overall structure is simple, and the applicability of existing parts processing is further optimized.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
