Description

Technical Field

[0001] The utility model relates to the technical field of die-casting part fixtures, and particularly relates to a finishing fixture for die-casting parts. Background Technique

[0002] A die-casting part is a part produced by die casting. A die-casting machine equipped with a die-casting mold is used to pour molten metals such as copper, zinc, aluminum, or aluminum alloy heated to a liquid state into the feed inlet of the die-casting machine. After die-casting by the die-casting machine, copper, zinc, aluminum parts, or aluminum alloy parts with shapes and sizes restricted by the mold are cast. Such parts are usually called die-casting parts. After die-casting parts are formed, for installation requirements, die-casting parts are usually clamped at a machining device for finishing.

[0003] Currently, when finishing the surface reaming or threading of die-casting parts, the die-casting parts usually need to be clamped. However, when clamping some arc-edge irregular die-casting parts with a middle hole, it is usually a two-way clamping by means of a fixture. When clamping such die-casting parts, the clamping area of the die-casting parts is small, making the die-casting parts prone to displacement during finishing, thus affecting the finishing dimensions of the die-casting parts. For this reason, we propose a finishing fixture for die-casting parts. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a finishing fixture for die-casting parts. By setting a fixture for finishing the die-casting part body, the fixture can be used to clamp and place some arc-edge irregular die-casting parts with a middle hole by means of a positioning table. Then, a push plate is driven by a double-headed cylinder to oppositely clamp the arc edge of the die-casting part body. After the die-casting part body is positioned and clamped, it can be stably clamped in opposite directions, effectively ensuring that the die-casting part body is not prone to displacement during finishing operations such as reaming and threading. Moreover, the conical table body of the positioning table can easily be inserted into the cavity of the die-casting part body, facilitating the quick positioning of the die-casting part body on the pallet for opposite clamping, shortening the clamping and positioning time during the finishing of the die-casting part body, and effectively solving the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A finishing fixture for die-cast parts, comprising a base mounting plate, a U-shaped support, a double-headed cylinder, a clamping plate, a support plate, a vertical connecting plate, a support plate, an upper connecting plate, a push plate and a positioning table. The U-shaped support is welded in the middle of the surface of the base mounting plate, and the double-headed cylinder is installed on the upper plate surface of the U-shaped support with bolts. Clamping plates are symmetrically installed at the two ends of the telescopic rod of the double-headed cylinder. A support plate is welded to the surface of the U-shaped support on one side of the double-headed cylinder with a vertical connecting plate. The support plate shields the double-headed cylinder. The opposite plate surfaces of the clamping plates are locked with support plates by bolts. An upper connecting plate is welded to the surface of the support plate, and a push plate pressing on the surface of the support plate is welded. A bent clamping groove surface is recessed on the outer plate surface of the push plate away from the upper connecting plate. A positioning table is screwed and installed on the surface of the support plate between the upper connecting plates, and a die-cast part body is placed and clamped at the positioning table. The arc-shaped plate body of the die-cast part body contacts the bent clamping groove surface of the push plate.

[0007] Further, the table body of the positioning table is a frustum-shaped table body, and a screwing hole for screwing bolts is provided between the positioning table and the support plate;

[0008] By adopting the above technical solution, the frustum-shaped table body of the positioning table and the support plate can be connected by screwing bolts through the screwing holes.

[0009] Further, the table body of the positioning table penetrates into the hole cavity on the surface of the die-cast part body;

[0010] By adopting the above technical solution, the frustum-shaped table body of the positioning table can be smoothly clamped with the hole cavity of the die-cast machine body.

[0011] Further, side mounting holes are symmetrically provided on the surface of the base mounting plate outside the U-shaped support;

[0012] By adopting the above technical solution, bolts can pass through the side mounting holes of the U-shaped support, so as to lock the U-shaped support at the machine table of the die-cast part finishing equipment.

[0013] Further, the upper connecting plate is vertically welded to the surface of the support plate, and the push plate is welded to the outer plate surface of the upper connecting plate away from the support plate;

[0014] By adopting the above technical solution, the support plate is connected to the push plate by welding the upper connecting plate.

[0015] Further, the interval height between the support plate and the U-shaped support is greater than the shell height of the double-headed cylinder, and bolts are screwed upward into the shell of the double-headed cylinder below the U-shaped support;

[0016] By adopting the above technical solution, the double-headed cylinder can be clamped between the support plate and the U-shaped support, and then the bolts can be screwed into the double-headed cylinder from below the U-shaped support for locking and installation.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model is provided with a fixture for finish machining of a die-casting body. The fixture can be used to clamp and place some arc-edge irregular die-castings with middle holes by means of a positioning table. Then, a push plate is driven by a double-headed air cylinder to oppositely clamp the arc edge of the die-casting body. After the die-casting body is positioned and clamped, it can be stably clamped oppositely, effectively ensuring that the die-casting body is not easy to move when undergoing finish machining such as reaming and threading.

[0019] Moreover, the conical table body of the positioning table can be easily inserted into the hole cavity of the die-casting body, facilitating the rapid positioning of the die-casting body at the pallet for opposite clamping, and shortening the clamping and positioning time during the finish machining of the die-casting body.

On the surface of the support plate 7 between the upper connecting plates 8, a positioning table 11 is screwed and installed with bolts, and a die-cast part body 14 is placed and clamped at the positioning table 11. The arc-shaped plate body of the die-cast part body 14 contacts the bent clamping groove surface 10 of the push plate 9.

[0026] Among them, the table body of the positioning table 11 is a frustum-shaped table body, and a screw hole 12 for screwing bolts is opened between the positioning table 11 and the support plate 7;

[0027] By adopting the above technical solution, the frustum-shaped table body of the positioning table 11 and the support plate 7 can be connected by screwing bolts through the screw hole 12.

[0028] Among them, the table body of the positioning table 11 penetrates into the hole cavity on the surface of the die-cast part body 14;

[0029] By adopting the above technical solution, the frustum-shaped table body of the positioning table 11 can be smoothly clamped with the hole cavity of the die-cast machine body 14.

[0030] Among them, side mounting holes 13 are symmetrically opened on the surface of the base mounting plate 1 outside the U-shaped support 2;

[0031] By adopting the above technical solution, bolts can pass through the side mounting holes 13 of the U-shaped support 2, so as to lock the U-shaped support 2 at the machine table of the die-cast part finishing equipment.
