The present invention was invented in order to solve the above-mentioned conventional drawbacks, and the problem is that a chuck member for holding a molded product that can change the mounting position and mounting angle with respect to the chuck plate by a simple operation. Is to provide.
[0006]
Another object of the present invention is to provide a chuck member for holding a molded product that can be used for a wide variety of chucks and can hold a molded product of various shapes with a single type of chuck and can reduce the chuck cost. Is to provide.
[0007]
[Means for Solving the Problems]
The present invention includes a driving member in which a holding pad that presses a molded product is reciprocated and a locking groove extending in a reciprocating direction of the holding pad is formed on an outer surface, and a head is secured to the locking groove. And at least two screw members supported so as to be movable in the moving direction of the holding pad, and a screw that is rotatably supported by inserting one screw member through an upright plate that stands on the edge of the flat surface portion. A mounting bracket provided with a cam hole for supporting the other screw member through a hole and an arc centered on the screw hole so as to be slidable, and a nut fixing to each screw member inserted through the screw hole and the cam hole And a nut member that fixes the drive member at an arbitrary position and angle with respect to the mounting bracket, and is capable of holding various molded products having different sizes and shapes.

FIG. 5 is a right side view of the molded product holding chuck member, FIG. 6 is a left side view of the molded product holding chuck member, and FIG. 7 is a bottom view of the molded product holding chuck member. FIG. 8 is a plan view of a molded product holding chuck member.
[0009]
The cylinder tube 3 in the chuck cylinder 1 as a chuck member for holding a molded product is an aluminum extrusion mold material, and a cylinder portion 3a having an axial line in the longitudinal direction inside, and a locking groove having a C-shaped cross section on the upper and lower sides of both sides. 3b is formed over the whole longitudinal direction.
[0010]
A piston 7 made of synthetic resin, such as polyamide resin, with a rod 5 integrated at the front end is supported in the cylinder portion 3a of the cylinder tube 3 so as to be slidable in the axial direction. A cover 9 for inserting the rod 5 and a closing plate 11 are screwed to the rear end of the cylinder tube 3 respectively. The closing plate 11 is hermetically sealed by an O-ring or the like with respect to the rear end portion of the cylinder tube 3.
[0011]
An elastic member 13 such as a compression spring is attached to the back pressure chamber side in the cylinder tube 3, and the piston 7 is always urged to the position shown in FIG. 3 by the elastic force of the elastic member 13.
[0012]
A nozzle 15 communicating with the inside is attached to the cylinder tube 3 on the positive pressure chamber side, and fluid such as compressed air is introduced into the positive pressure chamber of the cylinder tube 3 through the nozzle 15.
[0013]
Heads 17a and 19a of two screws 17 and 19 are supported in the lower locking grooves 3b on both side surfaces of the cylinder tube 3 so as to be slidable in the longitudinal direction. 21 and 23 are nut-stopped.
[0014]
Each of the mounting brackets 21 and 23 has a front L shape having upright plates 21b and 23b on one edge of the fixed plates 21a and 23a. A shaft support hole (not shown) is provided at the rear of the upright plates 21b and 23b. Arc-shaped cam holes 21d and 23d centering on the shaft support holes are formed at the front portions of the plates 21b and 23b, respectively, and screws 17 and 19 inserted into the shaft support holes and the cam holes 21d and 23d are nuts. It is fixed by screwing with 25 and 27.
[0015]
The fixing plates 21a and 23a are formed with screw holes 21e and 23e for inserting fixing screws 29 for fixing to the chuck plates (not shown).
[0016]
Next, a method for using the chuck cylinder 1 will be described.
FIG. 9 is an explanatory view showing a state in which the chuck cylinders are inclined, and FIG. 10 is an explanatory view showing a state of adjusting the interval between the chuck cylinders that are relatively arranged.
[0017]
First, the case of holding a molded product (not shown) having a side surface substantially orthogonal to the axis of the rod 5 will be described. The screw holes 21e and 23e of the mounting brackets 21 and 23 are inserted into the chuck plate 35. After fixing at least one pair of chuck cylinders 1 with a fixed screw 29 at a predetermined interval (an interval corresponding to the width of the molded product), the nuts 25 and 27 are loosened with respect to the screws 17 and 19 to attach the mounting bracket 21. After the chuck cylinder 1 is adjusted with respect to 23 so that the axis of the rod 5 is in a substantially horizontal state, nuts 25 and 27 are fastened and fixed to the screws 17 and 19.
[0018]
In this state, when the respective chuck cylinders 1 are operated with the molded products positioned between each other, the holding pads 37 attached to the shaft ends of the rods 5 are substantially flush with the side surfaces of the molded products. To hold the molded product.
[0019]
Next, when holding a narrow molded product, the nuts 25 and 27 for the screws 17 and 19 are loosened so that the chuck cylinder 1 can be rotated with respect to the mounting brackets 21 and 23, and then the locking groove. After the heads 17a and 19a of the screws 17 and 19 are moved in the direction in which the chuck cylinders 1 are close to 3b, nuts 25 and 27 are fastened and fixed to the screws 17 and 19. Thereby, the space | interval between the holding | maintenance pads 37 is narrowed, and it becomes possible to hold | maintain a narrow molded product.
[0020]
Next, when holding a molded product with inclined side surfaces, the nuts 25 and 27 are loosened with respect to the screws 17 and 19 so that the chuck cylinder 1 can be rotated with respect to the mounting brackets 21 and 23. After the screw 17 is slid in the cam holes 21d and 23d around the screw 19, the chuck cylinder 1 is made to be opposed to the mounting brackets 21 and 23, and the holding pad 37 is opposed to the inclined side surface of the molded product. Tighten nuts 25 and 27 to 19 and fix each chuck cylinder 1 to mounting brackets 21 and 23 in an inclined state.
[0021]
In the present embodiment, the holding pad 37 can arbitrarily change and adjust the interval between the chuck cylinders and the inclination angle according to the size and shape of the molded product, and the molded product can be reliably held.
[0022]
In the above description, the reciprocating drive member is the chuck cylinder 1, but an electromagnetic solenoid having an electromagnet and a plunger that moves in the axial direction by excitation of the electromagnet in a case having C-shaped locking grooves on both sides. Even if it exists, it can implement by attaching the same attachment bracket 21 * 23.
[0023]
In the present embodiment, a pair of left and right mounting brackets 21 and 23 are provided on the side surface of the chuck cylinder 1, but as shown in FIG. 11, shaft support holes 41b and cam holes 41c are formed on both side edges of the flat plate 41a. And a mounting bracket 41 having an upright plate 41d facing the chuck cylinder 1 in width.
[0024]
【The invention's effect】
In the present invention, the attachment position and the attachment angle with respect to the chuck plate can be changed by a simple operation. Further, the chuck can be made versatile, and a molded product of various shapes can be held by a single type of chuck, and the chuck cost can be reduced.
