Description

Technical Field

[0001] The utility model relates to the technical field of watch case preparation, in particular to a multi-directional clamping jig for watch cases. Background Art

[0002] During the watch manufacturing process, processing the watch case is a major manufacturing step. Surface inspection and deburring of the watch case require the use of a clamping jig to secure the case. Chinese Utility Model Publication No. CN218194852U proposes a "watch assembly fixture." This fixture utilizes a clamping member consisting of a support rod, an end plate, and a first spring, and an elastic member consisting of a second sleeve, a movable column, and a second spring to drive four fixing plates to clamp the watch from different directions. During use, the fixture is placed on a suitable workstation for the operator. The annular plate is then pulled outward using a telescopic member, depending on the operator's height, and secured using the fixing member. The corresponding watch component is then placed on the surface of the annular plate and secured using the clamping member. To clamp different types of watch components, the clamping plate can rotate the elastic member to increase the contact area with the outer surface of the watch component, further enhancing grip. This increases the contact area with the outer surface of the watch dial during the fixture's assembly process, thereby improving assembly stability and operational flexibility. However, the entire clamping process is mainly completed by the operator relying on physical strength to bend and pull, which consumes a lot of physical strength and is not conducive to improving production efficiency.

The piston rod of the driving cylinder is connected to a conversion seat, and the conversion seat is connected to an adjustment slide bar arranged along a second direction perpendicular to the first direction, and a conversion slide groove cooperating with the adjustment slide bar is formed on the conversion piece.

[0005] As a further solution of the present invention: two driving cylinders are installed on the connecting seat, and the conversion seat connected to each driving cylinder has an adjustment slide bar thereon that is in sliding cooperation with the conversion slide grooves on the two conversion parts.

[0006] As a further solution of the present invention: the conversion slide grooves on the two conversion members corresponding to each adjustment slide bar are the conversion slide grooves on two adjacent conversion members.

[0007] As a further solution of the present invention: the number of the driving cylinder is one, and the adjusting slide bar is extended into an adjusting slide plate that slidably cooperates with the conversion slide grooves on the four conversion parts.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 A multi-directional clamping fixture for a watch case includes a mounting seat 1, a case positioning seat 2 is provided on one side of the mounting seat 1, and correspondingly, the mounting seat 1 has a first side 101 for setting the case positioning seat 2 and a second side 102 arranged opposite to the first side 101.

[0021] The watch case positioning seat 2 has a height set along the first direction, so that the mobile phone case is placed on the watch case positioning seat 2 along the first direction.

[0022] like Figure 1 As shown, the case positioning seat 2 is provided with a lateral positioning protrusion 201 and / or a lateral positioning groove 202, so that after the watch case is placed on the case positioning seat 2, the lateral positioning protrusion 201 and / or the lateral positioning groove 202 correspond to the concave and / or convex parts on the watch case, so as to limit the rotational displacement of the watch case on the case positioning seat 2 with the first direction as its rotation axis.

[0023] Specifically, the watch case used for clamping is a mobile phone case with a mounting cavity on the back and / or front, and both sides of the watch case have lugs, and the lugs on both sides form a total of 4 lug corners.

[0024] When the watch case is placed on the case positioning seat 2 along the first direction, the case positioning seat 2 is correspondingly inserted into the mounting cavity on the watch case; the above-mentioned lateral positioning protrusion 201 and / or lateral positioning groove 202 are used to cooperate with the recessed portion and / or convex portion in the mounting cavity, so that the watch case is restricted to be able to move only in the first direction on the case positioning seat 2, or to be used to restrict the watch case to be able to deflect in other directions by a smaller amount.

[0025] The mounting cavity of a watch case is usually used to install internal watch components such as the movement and battery.

[0026] The mounting base 1 is provided with four oblique slots 5, which are arranged around the watch case positioning base 2 on the mounting base 1. The oblique slots 5 are arranged from the second side 102 of the mounting base 1 to the first side 101 of the mounting base and gradually tilt outward.

[0027] An adjusting slider 6 is slidably provided on the oblique slide groove 5; the portion of the adjusting slider 6 facing the first side 101 is connected to a connecting piece 7 located outside the oblique slide groove 5, and the connecting block 7 is detachably connected to a clamping block 8 for clamping the corner of the lug of the watch case; the portion of the adjusting slider 6 facing the second side 102 extends out of the oblique slide groove along the length direction of the oblique slide groove 5 to form a conversion piece 9.

[0028] A connecting base 10 is mounted on the mounting base 1 , and two driving cylinders, namely a first driving cylinder 3 and a second driving cylinder 4 , are mounted on the connecting base 10 .

[0029] The driving direction of the driving cylinders (3, 4) is the same as the first direction, a conversion seat 11 is connected to the piston rods of the driving cylinders (3, 4), an adjustment slide 12 arranged along a second direction perpendicular to the first direction is connected to the conversion seat 11, and a conversion slide 13 that cooperates with the adjustment slide 12 is formed on the conversion member 9; wherein, the conversion seat connected to each driving cylinder has an adjustment slide thereon that is slidably matched with the conversion slides on the two conversion members, that is, the two adjustment slides are slidably matched with the conversion slides on the two pairs of different conversion members respectively.

[0030] The control driving cylinder (3, 4) can be controlled to be telescopically driven, so that the conversion seat drives the adjusting slide bar 12 to move along the first direction. When the adjusting slide bar 12 moves along the first direction, the adjusting slide bar 12 can correspondingly push the adjusting slide bar 6 to slide along the length direction (oblique direction) of the oblique slide bar 5 on the oblique slide bar 5 by cooperating with the conversion slide bar 13. The configuration of the conversion slide bar 13 enables the thrust in the first direction applied by the adjusting slide bar 13 to the conversion member 9 to be converted into a power to drive the adjusting slide bar 6 to slide on the oblique slide bar 5 under the oblique abutment of the side wall of the adjusting slide bar 6 and the oblique slide bar 5, so that the clamping block 8 on the connecting member 7 can approach the watch case on the watch case positioning seat 2 and can move away from the watch case on the watch case positioning seat 2, so as to achieve the purpose of electrically controlled clamping and electrically controlled loosening, reduce the physical loss of the operator, and be more conducive to the improvement of production efficiency. Moreover, when electrically loosened, the distance between the clamping blocks 8 gradually increases, so that it is also more convenient to remove the watch case.

[0031] Preferably, the conversion sliding grooves on the pair of conversion members corresponding to each adjustment slide bar are conversion sliding grooves on two adjacent conversion members.

[0032] In other embodiments, the number of driving cylinders can be one, and correspondingly, the adjustment slide bar is extended to form an adjustment slide plate that can slidably cooperate with the conversion grooves on the four conversion members. One driving cylinder can simultaneously drive multiple clamping blocks to clamp and loosen the watch case, which is more conducive to cost reduction.

[0033] In this embodiment, the clamping block 8 is detachably connected to the connecting block 7 in the following manner: a card slot 14 is provided on the connecting member 7 along a third direction perpendicular to the first direction, and a connecting hole 15 is also provided on the connecting member 7 that connects to the card slot 14 along the first direction, as well as two positioning holes 16 that pass through the card slot 14 along the first direction.

[0034] The clamping block 8 has a connecting clamping block 17 that cooperates with the clamping slot 14 . The connecting clamping block 17 is formed with a connecting screw hole 18 corresponding to the connecting hole 15 and a through hole corresponding to the positioning hole 16 .

[0035] Connecting bolts 18 are provided to mate with connecting holes 15 and connecting screw holes 18, and positioning posts 20 are provided to mate with positioning holes 16 and the through-holes. After the connecting block 17 is inserted into place, the connecting bolts 19 can be tightened and the positioning posts 20 inserted to position the connecting block 17 on the connector 7. During clamping, the inner wall of the third-direction slot 14 can simultaneously provide a good pressing force for the clamping block 8.

[0036] In some embodiments, the clamping block 8 has a clamping side surface 21 corresponding to the lug corner of the watch case (case positioning seat).

[0037] The clamping side 21 is inclined from a position away from the corner of the lug (case positioning seat) to a position close to the corner of the lug (case positioning seat) and gradually away from the second side 102. Combined with the oblique clamping clamp 8, it can be used to clamp the lugs of different models of watch cases.

[0038] Preferably, the case locating seat 2 is detachably connected to the mounting seat 1. For example, the case locating seat 2 is tightened to the mounting seat 1 along a first direction using a bolt. The mounting seat 1 has a locating pin that corresponds to a pin hole in the case locating seat 2. This allows for replacement of lug locating seats of different models, thereby fully utilizing the clamp's adaptability to clamp the lugs of different watch case models.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
