Detailed Description
The following detailed description will be made with reference to the accompanying drawings and examples, so as to solve the technical problems by applying technical means to the present invention, and to fully understand and implement the technical effects of the present invention. It should be noted that, as long as no conflict is formed, the embodiments and the features in the embodiments of the present invention may be combined with each other, and the technical solutions formed are all within the scope of the present invention.
Specifically, as shown in fig. 1 to 3, the prior art has the following problems:
the T-shaped nut is inconvenient to disassemble. As most equipment workbenches are not provided with circular counter bores, the T-shaped nuts can only be inserted from two end heads of the workbench; the T-shaped nut is difficult to move left and right in a T-shaped groove on the workbench and can only move by sliding, and time and labor are wasted in the installation process.
And 2, the upper step surface of the T-shaped nut is easy to wear in the use process. After the workpiece is continuously clamped for several times, the surface in contact with the workbench is easy to wear, so that the step surface on the T-shaped nut is worn, no gripping force exists in the use process, the T-shaped nut is easy to slip under the condition of over-force, the T-shaped nut is scrapped, and the waste is serious.
The T-shaped nut is easy to slip when being screwed with the stud bolt in the using process, the return of the thread is often needed (the thread is passed through the screw thread by using the screw thread on the stud bolt), the auxiliary time for feeding the workpiece in the machining process is too long, the T-shaped nut is easy to slip, the thread is easy to pull off, the operation is inconvenient, the workpiece is not easy to compress, and the compression state of the workpiece is difficult to guarantee. If the workpiece and the workbench cannot be guaranteed to be in a compression state in the machining process, the resistance force generated by the workpiece in the machining process is too large, the machining size is out of tolerance, the workpiece is deformed possibly to cause quality safety accidents, and meanwhile, the normal use performance of the workpiece is influenced.
Therefore, as shown in fig. 4-6, the present invention is to overcome the above-mentioned deficiencies in the prior art, and to solve the problem that the workpiece is in a reliable pressing state on the worktable, a new design scheme of a diamond seat for pressing is provided. The stability of connecting workstation T type groove and work piece can be guaranteed, production efficiency is improved. The device has the advantages of simple structure, wide application range, convenient operation and convenient popularization and use.
Wherein, a lathe workstation compresses tightly with rhombus seat includes: the nut (1), the stud bolt (2), the workbench (3), the pressing plate (4), the cushion block (5) and the nut (6) with the shoulder are arranged, wherein the nut (1) is a T-shaped nut, a through hole matched with the bolt is arranged in the middle of the nut and is installed in a T-shaped groove in the workbench of the machine tool, the position of the bolt is fixed, the nut (1) is installed at one end of the stud bolt (2), the two ends of the stud bolt are provided with external threads, the stud bolt is installed from the two ends of the T-shaped groove in the workbench (3), in addition, the cushion block (5) is arranged on the workbench (3), the cushion block is a group of four cushion blocks with the same height and is arranged between the pressing plate (4) and the bolt as well as the pressing part; and the pressing plate (4) is arranged on the cushion block (5) and is pressed tightly by a nut (6) with a shoulder.
The using method comprises the following steps: according to the difference of different work piece height, width, the accessible increases or reduces the cushion highly to satisfy and compresses tightly the requirement, can adopt extension nut to increase the height of screw rod on its rhombus seat simultaneously, and the width direction can be adjusted by T type groove quantity front and back on the workstation, will compress tightly and put into T type inslot in the workstation with rhombus seat is perpendicular, anticlockwise rotation 90, after compressing tightly the position and confirming, adorn the cushion, couple together the fuselage with the clamp plate and compress tightly with the nut of taking the shoulder. The method of using the new diamond seat for compaction is shown in figure 5.
The novel diamond seat for compression is a whole, the diamond seat is vertically placed in a T-shaped groove in a workbench, after the diamond seat is rotated 90 degrees anticlockwise, two side faces are attached to two side faces of an upper T-shaped groove in the workbench, the diamond seat can rotate 90 degrees left and right in the T-shaped groove in the workbench 2, the degree of freedom is not limited, the diamond seat is perpendicular to the workbench face, a cushion block is mounted until the compression position of a machine body is determined, the machine body is connected through a pressing plate and compressed through a nut with a shoulder, the diamond seat is guaranteed to be perpendicular to the bottom face of the T-shaped groove in the workbench in the compression process, the diamond seat rotates 360 degrees clockwise during compression, the diamond seat cannot move in the T-shaped groove, the reverse chamfer angle on the diamond seat can increase the gripping force, and meanwhile the self-locking function is achieved. The other three parts are compacted by the same working principle in the same method. The pressing mechanism has a self-locking function, the diamond-shaped seat 1 cannot be separated from the pressing mechanism in the machining process, and the machining process is stable.
The novel diamond seat pressing method for pressing is used for processing, is mainly convenient to disassemble and easy to operate, and saves time and labor when pressing workpieces; meanwhile, due to the design of the new diamond-shaped seat for pressing, the phenomenon that the wires are slipped and frequently returned due to long-time disassembly of two parts together, so that the wires are not durable, is avoided; and an inverted chamfer is designed, so that the durability of the novel diamond seat for compression is improved. The processing quality and the processing precision of the workpiece are improved in the using process, the production efficiency is improved, and the use performance of the part is ensured.
The utility model discloses a key technology:
1. the design is novel to compress tightly and is a whole with the rhombus seat, satisfies the on-the-spot operation requirement.
2. When the novel diamond seat for compaction is manufactured, the novel diamond seat for compaction is required to be processed and formed once and then be subjected to heat treatment,
not only ensuring the manufacturing precision, but also reducing the manufacturing difficulty and cost.
3. The novel diamond seat for compressing is provided with the reverse chamfer, so that the service life is prolonged, and the durability is improved.
4. The novel diamond seat for compressing is provided with the reverse chamfer, the contact area of the novel diamond seat with the T-shaped groove of the machine tool is reduced, the friction force is increased, and the workpiece is stably and firmly clamped.
Through field practice and popularization, the diesel engine body, the crankshaft and the middle and small parts which are compacted before processing by adopting the novel diamond seat compacting method for compacting all meet the processing requirements, and are convenient to disassemble. The processing efficiency is improved, the auxiliary time is shortened, and the device is relatively durable. The use stability is good, and the processing quality, the processing precision and the use performance of parts are ensured.
Practice tests show that the novel diamond-base pressing mechanism for pressing has the advantages of simple structure, wide application range, convenience in operation, low production cost and convenience in popularization and use, and the processing mode is applied to multiple devices at present.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
