Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a double-sided machining clamping device. Background Technology

[0002] like Figure 1 The casting A shown has multiple mounting holes machined at its edges and multiple oblique holes machined on its sides after casting. Before machining the casting, a clamping fixture is used to hold and fix it. In the existing machining process, a single fixture is designed for machining the mounting holes, and multiple fixtures are designed for machining the oblique holes depending on the angle of the oblique holes. In actual production, the operator must first clamp the casting onto these fixtures in sequence and then fix these fixtures on the machine tool for machining. This method not only increases the manufacturing cost of the enterprise, but also has low production efficiency and increases the labor intensity of the enterprise's personnel.

[0003] To address the aforementioned problems, this application discloses a double-sided machining clamping device. Utility Model Content

[0012] More preferably, two raised blocks are provided below the first working surface, and the guide rods included in the two pressure plate assemblies are respectively fixed on the two raised blocks.

[0013] More preferably, the inner side of several pressure plate assemblies is provided with several corresponding pads, and some of the pads are provided with support columns for supporting the product.

[0014] More preferably, a deep groove ball bearing is provided above the second working surface, and a flat thrust ball bearing is connected to the deep groove ball bearing through a connecting shaft. The deep groove ball bearing and the flat thrust ball bearing are covered with a convex rotating cover with a hollow internal structure. A second nut is screwed into the hollow structure of the connecting shaft, and the disc is fixed to the outside of the convex rotating cover.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0027] In the description of this application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the component or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0028] Example

[0029] To address the limitation of existing technologies that cannot utilize a single clamping fixture... Figure 1 The problem of clamping castings for machining mounting holes and angled holes;

[0030] refer to Figures 1-6 As shown, this application provides a double-sided processing clamping device, including a base 10 and a stand 20 vertically disposed above the base 10. The stand 20 has a first working surface 21 and a second working surface 22.

[0031] A positioning component 30 for positioning the product ear seat is provided on one side below the first working surface 21. Several pressure plate components 40 for clamping the product are provided around the periphery of the first working surface 21. When machining the mounting holes of the casting, the operator places the casting to be cast on the first working surface 21 and positions it by the positioning component 30, and then clamps the casting by the several pressure plate components 40.

[0032] A disc 50 is rotatably mounted on the second working surface 22. The disc 50 has several locking holes 51 and several first pin holes 52 on its edge.

[0033] The stand 20 also has a second pin hole 221, and when a stop pin 60 is inserted into the second pin hole 221 from one of the first pin holes 52, the disc 50 stops rotating.

[0034] When machining oblique holes in a casting, the operator places the casting with the mounting holes on the second working surface 22 and screws into each mounting hole and into each locking hole 51 to fix the casting to the disc 50. Before machining the first oblique hole in the casting, a stop pin 60 is inserted from the first pin hole 52 to the second pin hole 221. After the oblique hole is machined, the stop pin 60 is pulled out and the operator rotates the disc 50 to the next position corresponding to the first pin hole 52 and the second pin hole 221. Then the operator inserts the stop pin 60 from this position into the first pin hole 52 to the second pin hole 221. The subsequent oblique hole machining is carried out in the same way, which will not be described in detail here.

[0035] In a preferred embodiment, in order to ensure the stability of the base 10 and the stand 20, the present application provides reinforcing ribs 140 between the base 10 and the two sides of the first working surface 21.

[0036] As an exemplary embodiment, the positioning component 30 of this application includes a fixed seat 31 obliquely disposed below the first working surface 21 of the stand 20, a square rod 32 inserted into the fixed seat 31, and a U-shaped block 33 integrally disposed at the head of the square rod 32. When the operator places the casting on the first working surface 21, one of the lugs of the casting will abut against the U-shaped block 33, thereby achieving precise positioning.

[0037] As an exemplary embodiment, the pressure plate assembly 40 of this application includes a guide rod 41 disposed on the first working surface 21 of the stand 20, a pressure plate member 42 inserted into the guide rod 41 through a guide hole 421, a through hole 422 opened in the pressure plate member 42, a screw 43 disposed on the first working surface 21 of the stand 20 through the through hole 422, and a first nut 44 screwed onto the top of the screw 43 above the pressure plate member 42. When the casting is pressed, the operator presses the pressure plate member 42 downward by turning the first nut 44 until it abuts against the edge of the casting. In order to adapt to the different heights of different positions of the casting, this application also provides two shims 70 below the first working surface 21. The guide rods 41 included in the two pressure plate assemblies 40 are respectively fixed on the two shims 70.

[0038] Based on the above embodiments, in order to cooperate with the plurality of pressure plate assemblies 40, this application also provides a plurality of corresponding pads 80 on the inner side of the plurality of pressure plate assemblies 40, and some of the pads 80 are provided with support columns 81 for supporting the product. In actual use, some parts of the casting directly contact the pads 80, and other parts need to contact the support columns 81.

[0039] To enable the disc 50 to rotate, this application provides a deep groove ball bearing 90 above the second working surface 22. The deep groove ball bearing 90 is connected to a planar thrust ball bearing 110 via a connecting shaft 100. A convex rotating cover 120 with a hollow internal structure is fitted around the deep groove ball bearing 90 and the planar thrust ball bearing 110. A second nut 130 is screwed into the hollow structure of the connecting shaft 100. The disc 50 is fixed to the outside of the convex rotating cover 120. Based on this structure, when the operator pushes the disc 50, the deep groove ball bearing 90 and the planar thrust ball bearing 110 will cooperate to make the convex rotating cover 120 rotate. At the same time, the disc 50 fixed on the convex rotating cover 120 will rotate.
