[0057] There are two fixture bodies 1 symmetrically distributed on the left and right, and the two fixture bodies 1 are synchronously driven to move toward and in opposite directions;

[0058] The fixture body 1 comprises:

[0059] The sliding mounting frame 11 has an inner side surface of a movable portion evenly fixed with an elastic clamping member 12 and an elastic adsorption assembly 13, which are used in conjunction with each other;

[0060] The elastic auxiliary positioning mechanism 14 has a connection fixing structure 16 installed between its lower end and the outer side surface of the movable part of the sliding mounting frame 11;

[0062] The upper end of the limit clamping mechanism 15 is clamped on the outer end of the elastic auxiliary positioning mechanism 14. When the elastic auxiliary positioning mechanism 14 is clamped, it is in an elastic contraction state, so that after the outer end of the elastic auxiliary positioning mechanism 14 is released from the limit, the elastic auxiliary positioning mechanism 14 is elastically reset as a whole.

[0063] In some embodiments, in order to achieve stable adsorption and clamping of the workpiece through the orderly arrangement of multiple elastic clamps 12 and elastic adsorption components 13, the number of elastic clamps 12 is at least three, the number of elastic adsorption components 13 is at least two, and the elastic clamps 12 and the elastic adsorption components 13 are distributed at intervals; the above is one of the arrangements of the elastic clamps 12 and the elastic adsorption components 13, and in other embodiments, there are other ordered or disordered arrangement methods.

[0064] In some embodiments, in order to slide and install wedge-shaped sliders 112 of different lengths, different numbers of elastic clamping members 12 and elastic adsorption components 13 are installed accordingly to clamp workpieces of different sizes. The sliding mounting frame 11 includes:

[0065] The horizontal plate 111 has a wedge-shaped sliding groove formed in the inner side thereof;

[0066] The wedge-shaped slider 112 is a movable part of the sliding mounting frame 11, and the wedge-shaped slider 112 is slidably engaged in the wedge-shaped sliding groove;

[0067] The elastic clamping member 12 and the elastic adsorption assembly 13 are evenly fixedly assembled on the inner side surface of the wedge-shaped sliding block 112 .

[0068] In some embodiments, in order to change the extension and contraction amount of the multiple elastic clamping members 12 according to the shape of the workpiece when clamping the workpiece, increase the contact area with the outer wall of the workpiece, and maintain stable clamping, the elastic clamping member 12 includes:

[0069] Three first gas springs 121 are distributed in parallel, and the three first gas springs 121 are vertically fixedly connected to the inner side surface of the wedge-shaped slider 112;

[0070] The telescopic end of the first gas spring 121 is fixedly connected to a first universal joint 122 , and the inner ends of the three first universal joints 122 are fixedly connected to clamping plates 123 .

[0071] In the above arrangement, three first gas springs 121 are installed on a clamping plate 123, and a long strip clamping plate 123 is turned over on the telescopic ends of the three first gas springs 121 through respective first universal joints 122, so as to adaptively clamp the workpiece according to the shape change of the outer wall of the workpiece;

[0072] In other embodiments, the clamp 123 is divided into three sections, and the telescopic ends of the three first gas springs 121 respectively fix a small clamp 123. In this way, the flipping angle of a small clamp 123 is more flexible, which is suitable for clamping workpieces with large changes in shape and can ensure that the contact area with the outer wall of such workpieces is sufficient.

[0073] In some embodiments, in order to first adsorb and position the workpiece when contacting the workpiece to avoid displacement of the workpiece during clamping, the elastic adsorption assembly 13 is composed of three parallel distributed elastic adsorption members, each of which includes:

[0074] A second gas spring 131, which is vertically fixedly connected to the inner side surface of the wedge-shaped slider 112;

[0075] The telescopic end of the second gas spring 131 is fixedly connected to the second universal joint 132, and the inner end of the second universal joint 132 is fixedly connected to the suction cup 133. The suction cup 133 is a silicone suction cup for adsorbing on the outer wall of the workpiece. Multiple suction cups 133 are used together, and sufficient adsorption and positioning strength can still be guaranteed when one or less than one-third of the suction cups 133 fail to adsorb.

[0076] In some embodiments, in order to elastically reset the elastic auxiliary positioning mechanism 14 when the corresponding limit clamping mechanism 15 is released, the multiple elastic auxiliary positioning mechanisms 14 that have been reset are pressed against the outer wall of the workpiece, and the multiple elastic auxiliary positioning mechanisms 14 on both sides work together to achieve auxiliary positioning. The elastic auxiliary positioning mechanism 14 includes:

[0077] The lower end of the vertical plate 141 is fixedly connected to the outer side surface of the movable part of the sliding mounting frame 11 through the connecting and fixing structure 16;

[0078] Round rods 142 are uniformly and horizontally passed through the upper end of the vertical plate 141, and both ends of the round rods 142 are fixedly assembled with limit plates 143;

[0079] A spring 144 is sleeved on the inner end of the outer wall of the round rod 142, and the two ends of the spring 144 are respectively against the corresponding inner limit plate 143 and the inner side surface of the vertical plate 141;

[0080] The upper end of the limit clamping mechanism 15 is clamped on the outer limit plate 143; when the corresponding limit clamping mechanism 15 is released, the spring 144 as an elastic device is restored and stretched from the compressed state, pushing the inner limit plate 143 to drive the round rod 142 to move, and the inner limit plate 143 is against the outer wall of the workpiece. The inner limit plate 143 is smaller in size and can better fit the outer wall of workpieces with different shapes.

[0081] In some embodiments, in order to clamp the outer end of the elastic auxiliary positioning mechanism 14 in the elastically compressed state to keep it in the elastically compressed state, the position limiting clamping mechanism 15 includes:

[0082] The upper end of the clamping plate 151 is provided in a clamping groove 153 corresponding to the round rod 142, and the round rod 142 is inserted into the corresponding clamping groove 153;

[0083] The outer diameter of the limiting plate 143 is greater than the width of the clamping groove 153, and the outer limiting plate 143 abuts against the outer edge of the clamping groove 153;

[0084] There are two electric push rods 152 distributed in parallel at the front and rear, and the telescopic upper ends of the two electric push rods 152 are fixedly connected to the same side of the bottom surface of the clamping plate 151; the limit plate 143 at the outer end of the round rod 142 is clamped in the corresponding clamping groove 153 of the clamping plate 151. When the electric push rod 152 works to drive the clamping plate 151 to descend as a whole, the round rod 142 disengages from the clamping groove 153, and the clamping state of the outer limit plate 143 is released.

[0085] In some embodiments, in order to fix the vertical plate 141, the horizontal plate 111 and the wedge-shaped slider 112 and facilitate their disassembly when necessary, the connection and fixing structure 16 includes:

[0086] The screw 161 passes through the vertical plate 141 and the horizontal plate 111 in a transverse direction, and corresponding through holes are reserved on the vertical plate 141 and the horizontal plate 111;

[0087] One end of the screw rod 161 is screwed and fixed to the outer side surface of the wedge-shaped slider 112, and the other end of the screw rod 161 is screwed to the limiting nut 162, and the limiting nut 162 abuts against the outer side surface of the vertical plate 141. After removing the limiting nut 162, the vertical plate 141 can be removed, and the screw rod 161 can be screwed off from the wedge-shaped slider 112, and the wedge-shaped slider 112 can be slid to be removed.

[0088] In some embodiments, in order to facilitate the synchronous driving of the clamp bodies 1 on both sides to move toward and in opposite directions, the following steps are also included:

[0089] A fixture mounting plate 2 is provided with a fixture driving structure 4, and the fixture driving structure 4 includes:

[0090] A strip-shaped groove 41 is transversely formed on the upper surface of the fixture mounting plate 2;

[0091] A double-headed screw 43 is rotatably mounted between the middle of the left and right sides of the inner wall of the strip-shaped groove 41;

[0092] The drive motor 42 has a rotating shaft that passes through the outer wall of the fixture mounting plate 2 and is fixedly connected to the end of the double-headed screw 43, and the housing of the drive motor 42 is fixedly connected to the outer wall of the fixture mounting plate 2;

[0093] Both ends of the double-headed screw 43 are screwed with connecting plates 44, and the connecting plates 44 are slidably assembled in the strip-shaped groove 41, and the connecting plates 44 on both sides are symmetrically distributed based on the middle part of the double-headed screw 43;

[0094] The middle part of the bottom surface of the sliding mounting frame 11 is fixedly connected to the upper end of the connecting plate 44 on the same side.

[0095] The driving motor 42 is connected to an external power source to drive the double-headed screw 43 to rotate. The double-headed screw 43 rotates clockwise to drive the connecting plates 44 on both sides to drive the clamp body 1 to move inward synchronously. Conversely, the double-headed screw 43 rotates counterclockwise to drive the connecting plates 44 on both sides to drive the clamp body 1 to move outward synchronously.

[0096] In some embodiments, in order to facilitate the device to be fixed on a vertical machining center for use, a connecting ear plate 3 is fixedly mounted on the lower edge of the outer wall of the fixture mounting plate 2, and the connecting ear plate 3 is fixed in a reserved screw hole on the vertical machining center with bolts.

[0097] Working principle:

[0098] The suction cup 133 of the elastic adsorption component 13 is a silicone suction cup, which is used to adsorb on the outer wall of the workpiece. The suction cups 133 of multiple elastic adsorption components 13 are used together to ensure the adsorption strength. When one or less than one third of the suction cups 133 fail to adsorb, sufficient adsorption and positioning strength can still be guaranteed;

[0099] The upper end of the limit clamping mechanism 15 is clamped at the outer limit plate 143; when the corresponding limit clamping mechanism 15 is released, the spring 144 as an elastic device is restored and stretched from the compressed state, pushing the inner limit plate 143 to drive the round rod 142 to move, and the inner limit plate 143 is against the outer wall of the workpiece. The inner limit plate 143 is smaller in size and can better fit the outer wall of the workpiece with different shapes.

[0100] After the electric push rod 152 in the limit clamping mechanism 15 works to drive the clamping plate 151 to descend as a whole, the round rod 142 disengages from the clamping groove 153, and the clamping state of the outer limit plate 143 is released. After the device is used, all the inner limit plates 143 on the same side are manually pushed so that the spring 144 is compressed again, the clamping plate 151 is raised, and the outer limit plate 143 on the round rod 142 is clamped again to prepare for the next use of the device.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
