[Industrial application field]

For example, when joining two pieces of wood with adhesive, the present invention can strengthen and securely bond both pieces of wood together. In fact, we have developed a vise that can be easily brought into contact and streamlined the joining of multiple members of this type. related.

0002

[Conventional technology]

A conventional vise of this type is disclosed in, for example, Japanese Utility Model Publication No. 46-25999. As disclosed, a threaded rod with a fastener at the tip and an expander at the rear end is screwed. The two arm rods are symmetrically supported in a bearing part constructed integrally with the mating female screw, and the arm rods are A fastener is provided at the tip of the expander, and each rear end is placed opposite the tapered surface of the expander to provide elasticity for outward opening. A three-way clamping vise is known in which a spring is provided on an arm rod to provide a spring.

0003

[Problem that the idea aims to solve]

The three-way tightening vise mentioned above has the advantage of being able to operate three fasteners simultaneously with one movement. Although it has a point, due to its structure, it is a fastener installed at the tip of one screw rod of this vise. The fasteners installed at the ends of both arm rods always move synchronously at a specified distance. For example, when two pieces of wood are pressed together with adhesive using this vise, A serious drawback is that the thickness and width of the two pieces of wood are limited to a certain length. At the same time, I held both pieces of wood with both hands until I could squeeze the two pieces of wood with the three-way clamp. There are operational difficulties such as the need to hold the Hand vises have extremely little practical value as vises for butt joining multiple parts. There's a problem.

0004 This invention was researched and developed with the aim of solving the above problems. When butt-joining multiple parts such as wood with adhesive, the thickness or width of the parts Even if the parts change from time to time, the members can be reliably joined with clamping pressure, and both Once the members have been butted together, you can take your hands off the members and press them with one hand. Easily and reliably butt-join multiple parts without the parts sliding during pressure operation. The purpose of the present invention is to provide a vise that is convenient and can achieve the desired results.

[0005]

[Means to solve the problem]

As a means to solve the above problems and achieve the purpose, in this invention, both base A frame with support legs protruding forward from the sides, and a frame with support legs protruding forward from the sides, and a The outer ends of a pair of clamping members each having a circumferential surface shaped like a bulging arc are pivotally connected to each other so as to be rotatable. a rotary clamping pressure member consisting of a rotary clamping pressure member, and a tip opposing portion of both rotary clamping pressure members at the base of the frame It consists of an operating rod with a pushing pressure member at the tip, which is screwed into the lever so that it can move forward and backward. A spring is provided to urge both of the rotation clamping pressure members to expand forward, and A stopper is provided to prevent the expansion biasing action of the spring at a predetermined position. Under normal conditions, the tips of both rotational clamping members are arranged close to each other and facing each other. We have developed and adopted a vise for joining multiple parts, which is characterized by the following characteristics:

[0006] In addition, in the present invention, in the vise for joining multiple members configured as described above, The bulging arc-shaped front circumferential surfaces of both rotating clamping members are made of rubber or other elastic material. A vise for joining multiple parts, which is characterized by rotating a pushing pressure member at the tip of the operating rod, In addition to being swingably mounted, the front face of the pushing clamp member is formed into a flat shape. We have developed and adopted a unique vise for joining multiple parts.

[0007]

[Effect]

Since the vise for joining multiple members according to _the present invention is configured as described above, for example, as shown in _FIG . Adhesive is applied to the joining end surface of the member _M1 , and the front face of the opposed end portions of the pair of clamping members 2a, 2a forming the rotating clamping member 2 is exposed to the end. When the entire vise is pushed forward using the operating rod 3, the member _M1 resists the elastic force of the spring 8 to expand and press against the bulging arcuate front surface of the clamping members 2a, 2a. While rotating both clamping pressure members 2a, 2a along , the frame 1 is smoothly pushed between the supporting legs 5, 5.

[0008] In this way, once the joining member _M1 is pushed between both supporting legs, both clamping pressure members 2a, 2a are urged by the spring 8 to expand and rotate forward, and both Since the outer end portions of the clamping members 2a, 2a are eccentrically pivotally connected to the supporting legs 5, 5 of the frame 1, they are clamped in an unretractable state.

Next, the joint end surface of the other joint member M ₂ is brought into contact with the joint end surface of the joint member M ₁ which is being clamped, and in this state, the operating rod 3 is rotated and screwed to open the tip end of the joint member M 2 . When the joining member M ₂ is pressurized by the pushing clamping pressure member 1 2 , both the joining members M ₁ and M ₂ have the clamping pressure fixing action of both the rotating clamping pressure members 2 a and 2 a and the clamping pressure fixing action of the pushing clamping pressure member 12 . Tightly joined by pressing action. At this time, the joining member M ₁ held under clamping pressure by the two rotating clamping pressure members 2a, 2a remains in an unretracted state due to the above-mentioned reason, so it is strongly tightened by the pushing clamping pressure member 12. Bonding becomes possible.

【Example】

Below, embodiments of the present invention will be described based on the attached drawings. The vice for joining parts can be roughly divided into a frame 1 that forms the main body, and a vice that rotates around the frame 1. Rotating clamping member 2 for clamping and fixing one movably pivoted joining member in a fixed position and an operating rod 3 for pressurized connection, which is screwed into the frame 1 so that it can move forward and backward. Ru.

[0011] Thus, the frame 1 has a pair of protrusions extending forward from both sides of the base 4. It is equipped with supporting legs 5, 5, and each supporting leg 5 is constructed in a bifurcated shape with a required distance maintained above and below. Therefore, the frame 1 has a total of four supporting legs.

0012 Further, the rotating clamping pressure member 2 is located at the tip between the two forked portions of both supporting legs 5, 5 of the frame 1. It is composed of a pair of clamping members 2a, 2a, which are interposed and pivotally connected to each other so as to be rotatable. The front peripheral surfaces of both clamping pressure members 2a, 2a are formed in a bulging arc shape, and gradually forming a gently curved surface from the outer end 6 toward the tip 7, The side shape resembles the shape of the head of a sickle.

[0013] Further, these clamping pressure members 2a, 2a have their respective outer ends 6 connected to the tips of both supporting legs 5, 5. The spring is eccentrically pivotally connected to the support leg 5, and has one end attached to each of the support legs 5 and 5 side. The other end of the gripping member 8 is engaged with the front end 7 side of the clamping pressure member 2a, 2a, and the clamping pressure member 2a, 2a to expand forward, and the spring 8 Both stoppers 9, 9 for blocking the expansion biasing action at a predetermined position are held by the pressing member 2a. , 2a protrude from the outer ends 6 of the stoppers 9, 9 and both supporting legs 5, 5 to collide with each other. In a normal state, the tip portions 7, 7 of the two clamping pressure members 2a, 2a are brought close to each other. It is configured to be placed facing each other in a state where the In addition, both clamp pressure members 2a, 2a An elastic member 1 made of an elastic piece of rubber or the like is provided on the front peripheral surface, that is, the clamping pressure surface of the members to be joined. 0 and 10 are attached, and the elastic members 10 and 10 prevent the joining during clamping. Measures are taken to prevent component damage and slippage.

[0014] Next, the operating rod 3 is screwed into the center of the base 4 of the frame 1 so that it can move forward and backward. A grip 11 is provided on the rear end side, and a joining member is pressurized and joined to the tip end. It is equipped with a pushing clamping pressure member 12 for 2a, 2a, and is arranged straight toward the opposite ends of the operating rod 3. A disk-shaped disk with a flat front surface, which is rotatably and swingably attached to the It is made up of the body.

[0015] Below, based on the embodiment configured as described above, the joining state of the two joining members M ₁ and M ₂ will be explained together with the effects. As explained in the operation section, for example, an adhesive is applied to the joining end surface of one joining member _M1 , and a pair of clamping pressure members 2a, 2 constituting the rotating clamping pressure member 2 is attached to the end thereof. When the entire vise is pushed forward by applying the front face of the tip facing part of a, the tip facing part is recessed in the shape of a valley as shown in _FIG . The supporting legs of the frame 1 are reliably guided along the bulging arcuate front surfaces of the clamping pressure members 2a, 2a against the biasing elastic force, and while rotating both clamping pressure members 2a, 2a. It is smoothly pushed in between 5 and 5.

Next, the joint end surface of the other joint member M ₂ is brought into contact with the joint end surface of the joint member M ₁ that is being clamped, and in this state, the operating rod 3 is rotated and screwed to open the tip end. When the joining member M ₂ is pressurized by the pushing clamping pressure members 1 and 2, both the joining members M ₁ and M ₂ perform the clamping pressure fixing action of both the rotating clamping pressure members 2a, 2a and the pressing force of the pushing clamping pressure member 12. A tight connection is achieved by the action. At this time, the joining member M ₁ which is clamped and fixed by both rotating clamping pressure members 2a, 2a is urged so that both clamping pressure members 2a, 2a are rotated and expanded forward by the spring 8. The outer ends 6, 6 of the two clamping pressure members 2a, 2a are eccentrically pivotally connected to the supporting legs 5, 5 of the frame 1, and the front peripheral surfaces of the two clamping pressure members 2a, 2a are Because the shape is formed into a gently curved surface whose curvature gradually decreases from the outer end 6 toward the tip 7 side, it is clamped and fixed in an unretractable state, so that it can be pushed forward. Strong tightening and joining by the clamping member 12 is possible.

Therefore, as shown in FIG. 3 or 4, for example, after the joining members M ₁ and M ₂ are brought into contact with each other, the joining operation can be easily accomplished by rotating the operating rod 3 with one hand. In addition, since the front circumferential surfaces (clamping surfaces) of the clamping pressure members 2a, 2a are formed of elastic members 10, 10, such as rubber, the joint member _M1 , which is clamped, may slip or be damaged. Not at all.

Further, the pushing clamp pressure member 12 at the tip of the operating rod 3 is attached so as to be rotatable and swingable, and the front surface is formed in a flat shape, so that the pushed clamping pressure part of the joint member M ₂ Pushing pressure can be achieved reliably even when the surface is inclined.

[0019] Although the main embodiments of the present invention have been described in detail above, the present invention is limited to the above embodiments. The scope is not limited to the extent that the purpose of the invention can be achieved and does not deviate from the gist of the invention. It goes without saying that various design changes can be made within the scope.
