[0002] Bottle making machines consist of many parts, such as... Figure 1 The bracket 2 shown is a type of part commonly used in bottle making machines. The characteristic of this type of part is that, due to the excessive overhang of its cantilever 201, the cantilever 201 is prone to deformation during processing, and the base plate 202 is not firmly fixed, causing vibration. Existing fixtures cannot avoid the above problems when fixing it, which affects the processing stability and reduces the part qualification rate.

[0003] Furthermore, since the processing positions of the bracket 2 are different, it is difficult to complete the processing of the cantilever 201 and the base 202 on the same fixture. How to complete the processing of different positions of the bracket 2 by the fixture while avoiding deformation during the processing of the cantilever 201, and with a simple structure, is a problem that needs to be solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a fixture suitable for processing brackets in bottle making machines, which can avoid deformation deviation of the cantilever and vibration of the base plate during processing, and can realize processing of different positions of the bracket.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The fixture applicable to the processing of brackets in a bottle making machine includes a base, and a first clamping mechanism is provided on the base. The bracket to be processed is horizontally fixed on the first clamping mechanism. The first clamping mechanism includes a longitudinal pressing arm, a support arm, a bottom plate positioning mechanism and a first positioning block. Two sets of longitudinal pressing arms are arranged opposite to each other. The support arm is located on the lower side of the longitudinal pressing arm. The first positioning block is located between the two sets of longitudinal pressing arms. The bottom plate positioning mechanism is located at one end of the base and between the two sets of longitudinal pressing arms.

[0006] The base plate positioning mechanism includes a positioning seat, a first fixed positioning block of the base plate, a base plate positioning hydraulic cylinder, and a second fixed positioning block of the base plate. The positioning seat is vertically mounted on the base. The first fixed positioning block of the base plate, the base plate positioning hydraulic cylinder, and the second fixed positioning block of the base plate are spaced apart on one side of the positioning seat. The base plate positioning hydraulic cylinder is located between the first fixed positioning block of the base plate and the second fixed positioning block of the base plate.

[0007] The base is also equipped with a second clamping mechanism, on which the bracket to be processed is longitudinally fixed.

[0008] Preferably, the second clamping mechanism includes a portal frame, on which a transverse clamping arm, a second positioning block, and a positioning post are provided. Multiple transverse clamping arms are respectively disposed on the portal frame and the base. The second positioning block is disposed on the portal frame and spaced apart from the transverse clamping arms. The transverse clamping arms disposed on the portal frame are clamped onto the cantilever, so that the cantilever is perpendicular to the base and disposed between the transverse clamping arm and the second positioning block. The positioning post is disposed on both sides of the base plate and passes through the positioning hole of the base plate from bottom to top.

[0009] Preferably, the portal frame includes two columns and two crossbeams disposed between the two columns. The two columns are vertically disposed on the base, and the transverse clamping arm and the second positioning block are disposed on the side adjacent to the two columns.

[0010] Preferably, the second clamping mechanism further includes an auxiliary positioning block, which consists of a lower fixing block and an upper support block. The fixing block is mounted on the portal frame, and the support block is mounted on the fixing block.

[0011] Preferably, the second clamping mechanism further includes a first auxiliary support arm and a second auxiliary support arm. The first auxiliary support arm is disposed on the crossbeam and inside the auxiliary positioning block. The auxiliary positioning block has a through hole for the first auxiliary support arm to pass through. The second auxiliary support arm is disposed on the column and is configured one-to-one with the transverse clamping arm.

[0012] Preferably, the longitudinal clamping arm is mounted on the base via a longitudinal hydraulic cylinder. One end of the longitudinal clamping arm is connected to the output end of the longitudinal hydraulic cylinder, and the middle part of the longitudinal clamping arm is rotatably connected to the longitudinal hydraulic cylinder via a connecting rod. The base is provided with a hydraulic oil circuit for supplying oil to the longitudinal hydraulic cylinder.

[0013] Preferably, the first clamping mechanism is further provided with a lateral clamping arm, which is mounted on the base via a lateral hydraulic cylinder and is respectively located on both sides of the cantilever.

[0015] Compared with existing technologies, the beneficial effects of this technical solution are:

[0016] This utility model uses a first clamping mechanism and a second clamping mechanism to clamp the bracket from different positions, satisfying the processing of the bracket at different positions. The longitudinal pressing arm of the first clamping mechanism cooperates with the support arm to fix the upper and lower sides of the cantilever. The first positioning block is locked between the two cantilever to position and fix the two cantilever. Then, the base plate positioning mechanism positions the base plate to achieve accurate fixation of the bracket. Furthermore, the first and second fixed positioning blocks of the base plate positioning mechanism perform preliminary positioning of the base plate. When the base plate is processed, the base plate positioning hydraulic cylinder presses against the base plate to ensure that the bracket does not vibrate during the processing.

[0022] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0023] Reference Figure 1The fixture for processing brackets in a bottle-making machine includes a base 1. The base 1 is equipped with three clamping mechanisms. The first clamping mechanism fixes the cantilever 201 of the bracket 2 to the base 1 in a direction parallel to the base 1, thereby enabling the processing of the base plate 202. The second clamping mechanism fixes the cantilever 201 of the bracket 2 to the base 1 in a direction perpendicular to the base 1, thereby enabling the processing of the cantilever 201. Two second clamping mechanisms are arranged side by side, enabling the simultaneous processing of two brackets 2.

[0024] Reference Figure 2 The first clamping mechanism includes a longitudinal clamping arm 3, a base plate positioning mechanism 6, and a first positioning block 5. The four longitudinal clamping arms 3 are arranged in pairs opposite to each other on the outside of the two cantilever 201. The two rows of support arms are respectively arranged on the lower side of the two sets of longitudinal clamping arms 3. The longitudinal clamping arms 3 of this utility model are powered by a longitudinal hydraulic cylinder 301. One end of the longitudinal clamping arm 3 is located at the output end of the longitudinal hydraulic cylinder 301. The middle part of the longitudinal clamping arm 3 is rotatably connected to the longitudinal hydraulic cylinder 301 through a connecting rod 302. One end of the longitudinal clamping arm 3 and the connecting rod 302 are connected through a rotating shaft. The upper end of the cylinder body of the longitudinal hydraulic cylinder 301 is connected to the other end of the connecting rod 302 through a rotating shaft. The base 1 is provided with a hydraulic oil circuit for supplying oil to the longitudinal hydraulic cylinder 301. When the cantilever 201 is parallel to the base 1, the longitudinal hydraulic cylinder 301 drives the longitudinal clamping arm 3 to swing up and down with the connecting rod 302 as the support point and press it against the upper side of the cantilever 201. It interacts with the support arm on the upper and lower sides of the cantilever 201 to achieve longitudinal fixation of the cantilever 201.

[0025] The first positioning block 5 is disposed between the two cantilever arms 201 to fix the cantilever arms 201 laterally. The first positioning block 5 is a rectangular block shape, and the width of the first positioning block 5 is equal to the width between the two cantilever arms 201. It plays a role in fixing the two cantilever arms 201. The contact area between the first positioning block 5 and the cantilever arms 201 is large, which can support the cantilever arms 201 and prevent deformation.

[0026] The lateral clamping arm includes a first lateral clamping arm 16, a second lateral clamping arm 18, a third lateral clamping arm 19, and a fourth lateral clamping arm 21. The two first lateral clamping arms 16 are disposed between the two cantilever arms 201. The second lateral clamping arm 18 and the third lateral clamping arm 19 are respectively disposed on the outside of the two cantilever arms 201. The second lateral clamping arm 18 and the two first lateral clamping arms 16 fix one of the cantilever arms 201, and the third lateral clamping arm 19 and the fourth lateral clamping arm 21 fix the other cantilever arm 201. The first lateral clamping arm 16, the second lateral clamping arm 18, the third lateral clamping arm 19, and the fourth lateral clamping arm 21 are powered by a lateral hydraulic cylinder. The first lateral clamping arm 16, the second lateral clamping arm 18, and the third lateral clamping arm 19 are located at the output end of the lateral hydraulic cylinder. The lateral hydraulic cylinder drives the first lateral clamping arm 16, the second lateral clamping arm 18, and the third lateral clamping arm 19 to directly clamp onto one side of the cantilever 201. The base 1 has a hydraulic oil circuit inside that supplies oil to the lateral hydraulic cylinder. The fourth lateral clamping arm 21 is connected to the lateral hydraulic cylinder via a rotating shaft. The fourth lateral clamping arm 21 passes through the bottom side of the cantilever 201 and swings to press against the inner side of the cantilever 201.

[0027] The base 1 is equipped with a sequence valve to control the switching of the longitudinal hydraulic cylinder 301 and the lateral hydraulic cylinder, thereby achieving orderly clamping of the bracket 2.

[0028] The support arms of this utility model include a first support arm 10, a second support arm 13, a third support arm 14, and a fourth support arm 15. The support arms are vertically mounted on the base 1, providing support for the bracket 2. The four support arms have different shapes. The first support arm 10 and the third support arm 14 have fixed heights. The working end of the first support arm 10 is cylindrical and contacts the lower side of the cantilever 201. The diameter of the working end of the third support arm 14 is smaller than the diameter of the working end of the first support arm 10. The second support arm 13 and the fourth support arm 15 are height-adjustable support arms, with their working ends spirally connected to the base, allowing for pre-adjustment according to the height of the cantilever 201. The working end of the second support arm 13 has the largest contact area with the cantilever 201, and its diameter is larger than that of the first support arm 10.

[0029] Reference Figure 3The base plate positioning mechanism 6 of the first clamping mechanism is located between the two cantilever arms 201. When the base plate 202 is processed, the base plate positioning mechanism 6 positions the base plate 202. The base plate positioning mechanism 6 includes a positioning seat 604 vertically mounted on the base 1. The positioning seat 604 is provided with a first fixed positioning block 601, a base plate positioning hydraulic cylinder 602, and a second fixed positioning block 603. The first fixed positioning block 601, the base plate positioning hydraulic cylinder 602, and the second fixed positioning block 603 are located on the side of the positioning seat 604 near the base plate 202. The base plate positioning hydraulic cylinder 602 is located between the first fixed positioning block 601 and the second fixed positioning block 603. The first fixed positioning block 601 and the second fixed positioning block 603 of the base plate play a preliminary positioning role for the base plate 202. The base plate positioning hydraulic cylinder 602 is set on the positioning seat 604 through the hydraulic cylinder. The base 1 and the positioning seat 604 are provided with hydraulic cylinder oil supply pipelines. The base plate positioning hydraulic cylinder 602 is pushed against the base plate 202, so that the entire bracket 2 avoids vibration during the processing.

[0030] Reference Figure 4 The second clamping mechanism includes a portal frame 7, which consists of two columns 701 and an upper crossbeam 702 and a lower crossbeam 703 horizontally arranged between the two columns 701. The adjacent side walls of the two columns 701 are provided with transverse clamping arms 4 and second positioning blocks 12 at intervals. The two crossbeams are provided with auxiliary positioning blocks 9, which work together to fix and position the cantilever 201.

[0031] Each column 701 is equipped with two second positioning blocks 12 and two transverse clamping arms 4. The second positioning blocks 12 are also rectangular blocks, and their width is equal to the width between the column 701 and the cantilever 201. They are in surface contact with the cantilever 201, providing support for it. The transverse clamping arms 4 have the same structure as the longitudinal clamping arms 3, and are also mounted on the column 701 and the base 1 via a transverse hydraulic cylinder 401. The transverse hydraulic cylinder 401 drives the transverse clamping arms 4 to rotate and clamp the side of the cantilever 201 away from the column 701. The side of the cantilever 201 closest to the column 701 is supported by the second auxiliary support arms 20 and the second positioning blocks 12. The two second auxiliary support arms 20 correspond one-to-one with the transverse clamping arms 4 and are positioned below the transverse clamping arms 4. The transverse clamping arms 4 are positioned to avoid the upper crossbeam 702 and the lower crossbeam 703.

[0032] The upper crossbeam 702 and the lower crossbeam 703 are each provided with two auxiliary positioning blocks 9. The auxiliary positioning block 9 is composed of a rectangular fixing block 901 and a cylindrical support block 902. The diameter of the cylindrical support block 902 is the same as the width of the fixing block 901, that is, the same as the width of the crossbeam, so as to achieve maximum contact with the cantilever 201. The side of the cantilever 201 is provided with multiple bolt holes. When it is processed, the auxiliary positioning block 9 can support the cantilever 201.

[0033] The auxiliary positioning block 9 has a through hole in the middle and a first auxiliary support arm 17 inside the auxiliary positioning block 9. The first auxiliary support arm 17 plays a positioning role for the cantilever 201. With the support of the auxiliary positioning block 9, the cantilever 201 can be prevented from deforming during processing.

[0034] The second clamping mechanism allows the base plate 202 to be horizontally positioned on the base 1. Similarly, the upper side of the base plate 202 is pressed by three transverse clamping arms 4, and the lower side of the base plate 202 is supported by the third support arm 14. Together, they fix the bracket 2. The base 1 is provided with a positioning post 8. The upper end of the vertical positioning post 8 is cylindrical and passes through the positioning hole 203 on the base plate 202 from bottom to top, thus positioning the base plate 202.

[0035] The four corners of the base 1 and the portal frame 7 are also equipped with lifting rings 11, which are used to lift the entire fixture onto the horizontal machining center and fix it in place.

[0036] Work process:

[0037] The bracket 2 is placed on the first clamping mechanism. The base plate 202 is initially positioned vertically by the first fixed positioning block 601 and the second fixed positioning block 603 of the base plate. The two cantilever arms 201 are placed on the support arm and positioned laterally by the first positioning plug 5. Then, the sequence valve is opened, and the two cantilever arms 201 and the base plate 202 are pressed in sequence by the longitudinal pressing arm 3, the first lateral pressing arm 16, the second lateral pressing arm 18, the third lateral pressing arm 19, the fourth lateral pressing arm 21 and the base plate positioning hydraulic cylinder 602, so as to process the base plate 202.

[0038] The bracket 2 is placed on the second clamping mechanism. The base plate 202 is positioned by the positioning column 8. At the same time, the two vertical cantilever 201 is positioned and supported by the second positioning block 12 and the auxiliary positioning block 9. The two cantilever 201 and the base plate 202 are pressed by the transverse clamping arm 4. After the bracket 2 is clamped by the second clamping mechanism, the cantilever 201 is processed.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
