Description

TECHNICAL FIELD

[0001] The present application relates to a vise with a chip preventing structure, belonging to the technical field of vises. BACKGROUND

[0002] The vise is also called flat mouthed pliers, which is a general type of clamp used to hold workpieces for machining, and is used in conjunction with milling machines and drilling machines for cutting. The existing vises on the market have a sliding groove for moving the movable vise body, and the upper opening of the sliding groove is a non-fully-closed structure. Once the waste chips and small parts fall into the sliding groove, the movable vise body is easy to be stuck and damaged.

[0003] For example, a flat mouthed pliers with quick replacement of jaw disclosed in patent publication No. CN213438417U discloses the common vise structure on the market, which includes a base, a fixed vise body, a fixed seat, a movable vise body and a screw rod (screw rod), the upper surface of the base is provided with a T-shaped sliding groove, one end of the T-shaped sliding groove is fixed with the fixed vise body, the other end is fixed with the fixed seat, the screw rod is screwed into the fixed seat, the movable vise body slides in the T-shaped sliding groove through the T-shaped sliding block at the bottom, and the screw rod on the fixed seat drives the movable vise body to move. In the above structure, there is a long T-shaped sliding groove (sliding groove) penetrating through both ends of the base in the middle of the base. During cutting or assembly operation, waste chips and small parts are easy to fall into the T-shaped sliding groove. The small waste chips in the sliding groove are difficult to clean, and the small parts are difficult to take out. When adjusting the forward and backward movement of the movable vise body, the movable vise body is difficult to move due to the blockage of the fallen waste chips and small parts, which is easy to cause the movable vise body to be stuck and worn out, not only reduces the service life of the vise, but also causes the CNC technician to have difficulty in operating the vise, the movable vise body does not slide smoothly, the adjustment operation experience is poor, the maintenance difficulty is increased, and time and effort are wasted.

DETAILED DESCRIPTION

[0056] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0057] As Figure 1 shown, the current market common vise structure, including the base 1, fixed body 2, fixed seat 504, movable body 3 and screw rod 4, the upper surface of the base 1 is provided with T-shaped sliding groove 101. One end of the T-shaped sliding groove 101 is fixed with the fixed body 2, and the other end is fixed with the fixed seat 504. The screw rod 4 is screwed into the fixed seat 504. The movable body 3 slides in the T-shaped sliding groove 101 through the T-shaped sliding block 501 at the bottom. Rotating the screw rod 4 on the fixed seat 504 drives the movable body 3 to move.

[0058] In the above structure, there is a long T-shaped sliding groove 101 (sliding groove) through the base 1 from both ends in the middle of the base 1. When cutting or assembling operations are performed, the T-shaped sliding groove 101 is easy to drop the waste and small parts inside. The small waste inside the T-shaped sliding groove 101 is difficult to clean, and the small parts are difficult to take out. When adjusting the front and back movement of the movable body 3, the movable body 3 is difficult to move due to the blockage of the dropped waste and small parts, which can easily cause the movable body 3 to be stuck and worn out. Not only does it reduce the service life of the vise, but it also makes it difficult for CNC technicians to operate the vise. The movable body 3 does not slide smoothly, the adjustment operation experience is poor, the maintenance difficulty is increased, and it is time-consuming and laborious.

[0059] As Figure 2 shown, in order to solve the above problems, a new vise structure with a chip prevention structure is designed as follows:

[0060] It includes base 1, fixed body 2, movable body 3 and screw rod 4, and also includes movable seat 5 and chip prevention sliding block 6. The upper surface of the base 1 is provided with a T-shaped sliding groove 101 through both ends. One end of the T-shaped sliding groove 101 is fixed with the fixed body 2 above. The fixed body 2 is fixed on the base 1 by screwing.

[0061] As Figures 3-9 shown, the bottom of the movable seat 5 is a T-shaped sliding block 501 matching the cross-sectional shape of the T-shaped sliding groove 101. The T-shaped sliding block 501 of the movable seat 5 is detachably fixed in the T-shaped sliding groove 101. The upper part of the movable seat 5 is provided with a threaded hole 503 through which the screw rod 4 is screwed. The central axis of the screw rod 4 is consistent with the sliding direction of the T-shaped sliding groove 101.

[0062] Among them, the detachable fixing structure of the movable seat 5 is that the side surface of the movable seat 5 is provided with a positioning screw 9 inserted obliquely into the bottom of the movable seat 5. The movable seat 5 is tightly fixed with the bottom of the T-shaped sliding groove 101 by rotating the positioning screw 9 downward.

[0063] The bottom surface of the movable vice body 3 is fixed with a T-shaped guide sliding block 301 which is in conformity with the cross-sectional shape of the T-shaped sliding groove 101. The T-shaped guide sliding block 301 is inserted into the T-shaped sliding groove 101 between the movable seat 5 and the fixed vice body 2. The movable vice body 3 is movably connected to one end of the lead screw 4. The other end of the lead screw 4 is provided with a hexagonal screw head 401. The lead screw 4 is twisted to rotate through the hexagonal screw head 401. The movable vice body 3 is driven to translate along the T-shaped sliding groove 101 through the lead screw 4. One end of the lead screw 4 is inserted into the end surface of the movable vice body 3. The screw is screwed into the limiting groove at the end of the lead screw 4 in the movable vice body 3 to form a movable connection structure in which the lead screw can rotate but will not be separated from the movable vice body 3 (the movable connection structure of the vice is prior art and is not shown in the figure).

[0064] The T-shaped sliding block 501 of the movable seat 5 is provided with an extension segment 502 extending below the movable vice body 3. When the movable vice body 3 is in the initial position in contact with the movable seat 5, the extension segment 502 and the T-shaped guide sliding block 301 abut together. The extension segment 502 has the same cross-sectional shape as the T-shaped sliding groove 101. The upper surface of the extension segment 502 is flush with the slot of the T-shaped sliding groove 101. When the movable vice body 3 is separated from the movable seat 5 and reaches the farthest position under the driving of the lead screw 4, the gap between the extension segment 502 and the T-shaped guide sliding block 301 is still completely covered by the movable vice body 3.

[0065] The T-shaped sliding block 501 of the movable seat 5 is provided with an extension segment 502 extending below the movable vice body 3. When the movable vice body 3 is in the initial position in contact with the movable seat 5, the extension segment 502 and the T-shaped guide sliding block 301 abut together. The extension segment 502 has the same cross-sectional shape as the T-shaped sliding groove 101. The upper surface of the extension segment 502 is flush with the slot of the T-shaped sliding groove 101. When the movable vice body 3 is separated from the movable seat 5 and reaches the farthest position under the driving of the lead screw 4, the gap between the extension segment 502 and the T-shaped guide sliding block 301 is still completely covered by the movable vice body 3.

[0066] As shown in Figures 10-12 , Figures 20-22 , in order to further prevent fine debris from entering the inside from the gap between the T-shaped sliding groove 101 and the debris prevention sliding block 6, the gap on both sides of the slot is set as a cover structure.

[0067] The slots on both sides of the T-shaped sliding groove 101 are provided with chamfers 102. The top of the debris prevention sliding block 6 extends to both sides and is provided with a pressing edge 601 which cooperates with the chamfer 102 of the slot of the T-shaped sliding groove 101.

[0068] In order to further tighten the covering structure without affecting the smooth sliding of the anti-dumping slider 6, an elastic pressing structure is designed to press the pressing edge 601 of the anti-dumping slider 6 against the chamfer 102 of the T-shaped groove 101.

[0069] Arc-shaped spring pieces 7 are provided in the gaps between the shoulder portions 602 on both sides of the anti-chip slider 6 and the top of the T-shaped groove 101 on both sides. The two ends of the arc-shaped spring pieces 7 are fixed to the shoulder portions 602 of the anti-chip slider 6. Preferably, such as Figure 11 As shown, the anti-chip slider 6 has a pair of arc-shaped spring pieces 7 near its front and rear ends. Each anti-chip slider 6 has four arc-shaped spring pieces 7 mounted on its shoulder 602. The center of each arc-shaped spring piece 7 protrudes and contacts the top of the T-shaped groove 101. Under the pressure of the arc-shaped spring pieces 7, the pressing edge 601 of the anti-chip slider 6 tightly engages with the chamfer 102 of the T-shaped groove 101. The arc-shaped structure of the arc-shaped spring pieces 7 ensures smooth sliding of the anti-chip slider 6. The T-shaped groove 101 described in this article refers not only to a strictly T-shaped groove but also to a T-shaped groove 101 with a large inner cavity and a small opening, which can press down on the shoulder 602 of the slider inside the groove to prevent it from detaching upwards from the groove opening. Both the T-shaped groove and the T-shaped groove are collectively referred to as the T-shaped groove 101.

[0070] Based on the above solutions, in order to ensure that the anti-chip slider 6 can be quickly connected and disassembled, maintain strong connection force, and have good reusability and fatigue resistance, the following additional measures are taken.

[0071] like Figures 10-12 As shown, in the first quick-connect structure scheme, the quick-connect structure adopts a magnetic adsorption structure. The quick-connect structure consists of magnets 8 fixed at both ends of the chip-proof slider 6 and attracting each other. One end is an S-pole magnet and the other end is an N-pole magnet. The magnets 8 are flush with the end faces of the chip-proof slider 6. The T-shaped slider 501 and the T-shaped guide slider 301 are both made of steel and are attracted to the magnets 8.

[0072] like Figures 13-15 As shown in the second quick-connect structure, the quick-connect structure can also employ a diamond-shaped clamping arm 801 and a clamping seat 802. The clamping seat 802 has a clamping groove 803 that mates with the diamond-shaped clamping arm 801. The clamping groove 803 has a small opening and a large center, and the opening of the clamping groove 803 has a central elastic clamping force. The diamond-shaped clamping arm 801 and the clamping seat 802 are respectively installed at the beginning and end of the anti-chip slider 6 and at the connection end between the T-shaped slider 501, the T-shaped guide slider 301 and the anti-chip slider 6. The diamond-shaped clamping arm 801 protrudes and is fixed on the outside of the end, and the clamping seat 802 is embedded in the cavity 809 inside the end face. When the operator inserts the diamond-shaped clamping arm 801 into the clamping seat 802, the diamond-shaped clamping arm 801 squeezes and deforms the opening of the clamping seat 802 and then snaps into the inside of the clamping seat 802. When the quick-connect structure is clamped and fixed, the two adjacent end faces are tightly connected to prevent waste chips from entering.

[0073] As Figures 16-19 shown, the quick connection structure scheme three, the quick connection structure can also adopt the spherical clamping arm 804 and the ball clamping seat 805. The spherical clamping arm 804 and the ball clamping seat 805 are respectively installed at the head and tail of the chip removal slider 6 and the connecting end of the T-shaped slider 501, the T-shaped guide slider 301 and the chip removal slider 6, wherein the spherical clamping arm 804 is protrudingly fixed outside the end, the ball clamping seat 805 is embedded in the cavity 809 inside the end, the operator inserts the spherical clamping arm 804 into the ball clamping seat 805, a pair of elastic expansion balls 806 are arranged on both sides of the ball clamping seat 805, the balls 806 are ejected by the spring 807 arranged inside the guide sleeve 808, only a small part of the balls 806 is exposed, the main body of the ball 806 is limited in the opening of the guide sleeve 808 (the opening diameter is smaller than the diameter of the ball 806), the ball 806 is expanded and contracted by the spring 807, the recess 808 is arranged at the rear of the head of the spherical clamping arm 804 and cooperates with the ball 806, the spherical clamping arm 804 is inserted between the elastic expansion balls 806 on both sides of the ball clamping seat 805, the ball 806 is first squeezed and compressed into the guide sleeve 808 by the head of the spherical clamping arm 804, with the passing of the spherical clamping arm 804, the ball 806 is gradually expanded and pressed into the recess 808 of the spherical clamping arm 804 under the action of the spring 807, and the two are clamped and fixed. When the quick connection structure is clamped and fixed, the two adjacent end faces are tightly connected to prevent the entry of chips.

[0074] As Figures 23-26 shown, in order to adapt to workpieces of different sizes, the clamping distance between the fixed jaw body 2 and the movable jaw body 3 can be adjusted by a short distance through the lead screw 4 or adjusted by a long distance through the fixed position of the movable seat 5.

[0075] As Figure 23 shown, the movable seat 5 is installed at the end, and except for the space occupied by the movable seat 5 and the movable jaw body 3, the other space of the T-shaped sliding groove is filled by the four chip removal sliders a, b, c and d, at this time, the opening degree of the jaw is the largest, and a larger size workpiece can be fixed.

[0076] As Figure 24 shown, the movable seat 5 is translated to the middle part by a distance of a chip removal slider 6, and except for the space occupied by the movable seat 5 and the movable jaw body 3, the other space of the T-shaped sliding groove is still filled by the four chip removal sliders a, b, c and d, only the d chip removal slider 6 is located outside the movable seat 5, at this time, the opening degree of the jaw is reduced, and a smaller workpiece can be fixed. Similarly, the movable seat 5 can be further translated to the end of the fixed jaw body 2, which is more suitable for smaller workpieces.

[0077] As Figure 25 , Figure 26As shown, the bottom of the positioning screw 9 is connected with a ball 901, and the bottom surface of the T-shaped sliding groove 101 is provided with a series of spherical position grooves 103 matched with the ball 901 in the sliding direction. When disassembling, the ball 901 is retracted into the movable seat 5, and when assembling, the ball 901 is tightly contacted with the spherical position groove 103 by rotating the positioning screw 9 downward, so as to fix the movable seat 5 and the T-shaped sliding groove 101. The positioning screw 9 is rotated and extended from the bottom of the movable seat 5, the ball 901 is sleeved at the bottom end of the positioning screw 9, and the two are fixed from the side through the screw.

[0078] In summary, the vice structure has the following advantages:

[0079] (1) The T-shaped sliding groove 101 is filled with the anti-dust sliding block 6, and the upper opening of the T-shaped sliding groove 101 is completely closed, so that the waste dust and small parts in the T-shaped sliding groove 101 are prevented from falling, the operation of the vice is smoother, the working efficiency of the operator is improved, the operation difficulty is reduced, and the service life of the vice is prolonged;

[0080] (2) The pressing edge 601 matched with the chamfer 102 of the T-shaped sliding groove 101 is arranged on the anti-dust sliding block 6, so that the fine waste dust is further prevented from entering the inside from the gap between the T-shaped sliding groove 101 and the anti-dust sliding block 6;

[0081] (3) The downward pressure provided by the arc-shaped elastic piece 7 can further press the pressing edge 601 of the anti-dust sliding block 6 and the chamfer 102 of the T-shaped sliding groove 101, so that the anti-dust effect is better, and the smoothness of the sliding of the anti-dust sliding block 6 is not affected;

[0082] (4) The quick connection structure adopts a magnetic adsorption structure, which can be quickly connected and disassembled, can maintain a strong connection force, and has good reusability and fatigue resistance;

[0083] (5) The fixed position of the movable seat 5 is adjustable, and can be adapted to more workpieces of different sizes.

[0084] The basic principles, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and various changes and improvements can be made without departing from the spirit and scope of the present application. These changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.

When the movable forceps body is separated from the movable seat and reaches the farthest position under the drive of the lead screw, the gap between the extension section and the T-shaped guide slider is still completely covered by the movable forceps body above. The chip-proof sliders are the same as the cross-sectional shape of the T-shaped sliding groove. When the extension section of the T-shaped slider and the T-shaped guide slider are in contact, a plurality of modular chip-proof sliders are inserted into the T-shaped sliding groove in turn, and the remaining space of the T-shaped sliding groove is completely filled. The chip-proof sliders are connected by quick connection structure between each other, between the chip-proof sliders and the T-shaped slider, and between the chip-proof sliders and the T-shaped guide slider. The upper surface of the chip-proof slider does not protrude from the notch of the T-shaped sliding groove. The notches on both sides of the T-shaped sliding groove are provided with chamfers, and the top of the chip-proof slider is provided with a pressing edge which cooperates with the chamfer of the notch of the T-shaped sliding groove. Arc-shaped elastic pieces are arranged in the gap between the shoulder of the chip-proof slider and the top of the T-shaped sliding groove. The two ends of the arc-shaped elastic pieces are fixed on the shoulder of the chip-proof slider. The middle part of the arc-shaped elastic pieces protrudes and contacts the top of the T-shaped sliding groove. The pressing edge of the chip-proof slider is tightly matched with the chamfer of the notch of the T-shaped sliding groove under the pressure of the arc-shaped elastic pieces. The quick connection structure is a magnet fixed at the two ends of the chip-proof slider and attracting each other. One end is an S-pole magnet, and the other end is an N-pole magnet. The magnet is flush with the end surface of the chip-proof slider. The T-shaped slider and the T-shaped guide slider are made of steel sliders which are attracted to the magnet.

The vice having a chip preventing structure according to claim 1, wherein The side surface of the movable seat is provided with a positioning screw which is obliquely inserted into the bottom of the movable seat. The movable seat is tightly fixed with the bottom of the T-shaped sliding groove by rotating the positioning screw downward.

3. The vice according to claim 2, wherein The bottom of the positioning screw is connected with a ball. A series of spherical gear slots which cooperate with the ball are arranged on the bottom surface of the T-shaped sliding groove along the sliding direction. When disassembling, the ball is retracted into the movable seat. When assembling, the ball is tightly fixed with the spherical gear slots by rotating the positioning screw downward, thereby fixing the movable seat with the T-shaped sliding groove.
