The utility model adopts the following technical scheme:

a wax mould processing combined clamp comprises a tray and a supporting seat arranged on the tray, wherein a positioning groove vertical to the tray is formed in the middle of the supporting seat; brackets are arranged at two ends of the supporting seat, and semicircular holes with opposite openings are respectively arranged on the brackets at the two ends; the semicircular holes are arranged in a concentric shaft mode, and the central shaft is parallel to the tray.

Furthermore, a fixed seat arranged in parallel with the supporting seat is also arranged on the tray; the fixing seat is provided with a positioning hole.

Further, the semicircular hole opening faces vertically upwards or vertically downwards.

Furthermore, a round hole is formed in the bottom of the positioning groove; the diameter of the round hole is the same as that of one of the semicircular holes.

Furthermore, a horn-shaped opening is formed in the outer side of the positioning groove.

Further, the tray comprises an upper disc and a lower disc; the upper and lower discs are connected and fixed through bolts.

Furthermore, symmetrical handles are arranged on the circumference of the lower disc.

Further, the bottom of the tray is connected with a rotating base.

The utility model discloses can be according to the needs of actual processing, switch the gesture that the wax matrix adds man-hour, can carry out horizontal processing and vertical processing to the wax matrix simultaneously on same anchor clamps to can rotate, and the installation is simple and convenient with the dismantlement, and the manufacturing cost of time cost and anchor clamps has been saved to the machining efficiency of improvement.

Detailed Description

The invention is further described with reference to the following figures and examples. In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and the like are used in the indicated orientations and positional relationships based on the orientation shown in the drawings for convenience in describing the invention and simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus are not to be considered as limiting.

As shown in the figure, the present embodiment provides a wax mold processing clamp, which comprises a tray 1 and a support seat, wherein the tray comprises an upper tray and a lower tray, the upper tray and the lower tray are fixed together through M8 bolts uniformly distributed at 3 positions, and symmetrical handles 4 are arranged on the circumference of the lower tray; the supporting seat is welded on the upper disc and consists of two brackets 2 and a middle connecting plate 3, wherein the middle connecting plate 3 is provided with an opening so as to form a vertical positioning groove 31, a round hole 32 is arranged on a tray at the bottom of the positioning groove,

semicircular holes

21 and 22 with opposite openings are arranged on the two brackets, the two semicircular holes are arranged on the same straight line, namely, are arranged with the same central shaft, the central shaft is parallel to the tray, the opening of the semicircular hole 21 is vertically downward, the opening of the semicircular hole 22 is vertically upward, and the diameter of the round hole 32 at the bottom of the positioning groove 31 is consistent with the diameter of one of the semicircular holes; a trumpet-shaped opening is arranged outside the positioning groove 31; the tray 1 is further provided with a fixed seat 5 arranged in parallel with the supporting seat, the fixed seat 5 and the positioning groove 31 are arranged on the same central axis, the fixed seat is provided with a positioning hole 51, and the axis of the positioning hole is perpendicular to the axes of the

semicircular holes

21 and 22.

As shown in fig. 5, fig. 5 is a connecting rod for wax pattern machining, and the connecting rod 6 includes a main shaft and a branch 61 perpendicular to the main shaft, wherein an end of the main shaft away from the branch 61 is used for fixing a wax pattern.

The utility model discloses a concrete working method as follows: the wax mould to be processed is fixed on the connecting rod 6, when the wax mould is horizontally processed, the main shaft of the connecting rod 6 is fixed in the

semicircular holes

21 and 22 at two sides of the bracket 2, and because the openings of the

semicircular holes

21 and 22 are respectively vertically downward and vertically upward, the connecting rod 6 and the wax mould can be axially limited, the wax mould is prevented from being turned upwards or downwards, and meanwhile, the connecting rod can be manually rotated around the axes of the

semicircular holes

21 and 22, so that the axial processing part of the wax mould is changed; when the wax mould to be processed is vertically processed, one end of the connecting rod main shaft, which is close to the branch 61, can be downwards inserted into the positioning groove 31 at the middle connecting plate 3 and the round hole 32 on the tray, and meanwhile, the branch 61 of the connecting rod 6 is inserted into the positioning hole 51 of the fixed seat 5, so that the connecting rod and the wax mould can be fully limited; meanwhile, the bottom of the tray 1 is connected with a rotating base, when a worker holds the main shaft of the connecting rod 6 to rotate, the branch acting force of the main shaft on the fixing seat 5 can drive the whole tray to rotate, and therefore the radial machining position of a wax mould facing the worker is changed.
