[0001] The utility model belongs to the technical field of mechanical clamps, and in particular relates to a brick clamping mechanism. Background Art

[0002] As a basic building material, fired bricks are widely used in the construction industry. In the brick production process, the degree of mechanization and automation is high. However, the number of mechanized production equipment related to finished bricks is relatively small.

DETAILED DESCRIPTION

[0028] The utility model will be further described below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] Reference Figure 1-Figure 2 As shown, a brick clamping mechanism of this embodiment includes a slide 1, a first clamping module 2a, a second clamping module 2b, a clamping unit 2, a spacing adjustment component 3 and a mounting seat 4.

[0031] In this embodiment, the slide 1 specifically includes a connecting plate 11, a connecting rod 12, and a slide rail 13. There are two connecting plates 11 and two connecting rods 12, and the two connecting plates 11 are respectively fixed to the front end and the rear end of the two connecting rods 12 by a plurality of bolts. In this embodiment, there are also two slide rails 13, and the two slide rails 13 are respectively fixed to the two connecting rods 12 by a plurality of bolts.

[0032] This embodiment has a first clamping module 2a and three second clamping modules 2b. The first clamping module 2a of this embodiment has a clamping unit 2, and the three second clamping modules 2b are all a clamping unit 2. The clamping unit 2 is used to clamp a row of bricks. Multiple clamping units 2 can clamp multiple rows of bricks respectively. The clamping unit 2 can be driven by air pressure, hydraulic pressure or motor. In addition, it can be considered to set the clamping action of the clamping unit 2 to an independent control mode, that is, to make the clamping actions of each clamping unit 2 not affect each other, so as to more flexibly control the specific clamping quantity.

[0033] In this embodiment, the total number of clamping units 2 is 4, and the 4 clamping units 2 are arranged side by side on the slide 1. Specifically, among the 4 clamping units 2, the last clamping unit 2 (that is, the clamping unit 2 of the first clamping module 2a) is fixedly connected to the slide 1 through bolts and nuts, and the remaining clamping units 2 are slidably connected to the two slide rails 13 of the slide 1 through their own two slide seats 21. It is worth mentioning that the last clamping unit 2 also has two slide seats 21 assembled with the slide rails 13, so that the connection strength between the last clamping unit 2 and the slide 1 can be improved.

[0034] Furthermore, the two slide rails 13 of the present embodiment are respectively arranged on opposite sides of the two connecting rods 12, so that the longitudinal height of the brick clamping mechanism can be reduced to a certain extent. In addition, this arrangement is conducive to disassembly, assembly and maintenance.

[0035] In this embodiment, the mounting seat 4 is fixedly connected to the slide 1 by a plurality of bolts, and is specifically fixed to the upper side of the slide 1. The mounting seat 4 of this embodiment is in a hollow cylindrical shape, with a flange plate welded to the upper end for connecting to the transfer device, and a bottom plate welded to the lower end for connecting to the slide 1, and a plurality of reinforcing rib plates are welded between the main body, the flange plate and the bottom plate.

[0036] In this embodiment, the spacing adjustment component 3 specifically includes a driver 31 and a spacing limiter 32. The number of spacing limiters 32 in this embodiment is 3 groups, and the 3 groups of spacing limiters 32 are arranged between the first clamping module 2a and the second clamping module 2b and between the second clamping module 2b and the second clamping module 2b to constrain the maximum spacing and minimum spacing between the clamping modules. Specifically in this embodiment, the 3 groups of spacing limiters 32 are arranged in sequence from back to front between two adjacent clamping units 2 to constrain the maximum spacing and minimum spacing between any two adjacent clamping units 2.

[0037] In this embodiment, the spacing limiter 32 specifically includes a slide bar 321, a front stopper 322, a rear stopper 323, a fixing member 324 and a sliding member 325. The front stopper 322 and the rear stopper 323 are fixedly connected to the slide bar 321 at intervals. The slide bar 321 is specifically a longer bolt. The front stopper 322 and the rear stopper 323 are both composed of two nuts and a washer. The two nuts are threadedly connected to the outside of the bolt, and the washer is located between the two nuts. The two nuts and the washer are pressed against each other to form a stopper fixed to the bolt column of the bolt. This form of stopper is convenient for subsequent adjustment of the front and rear positions to change the maximum spacing and minimum spacing between two adjacent clamping units 2. The sliding member 325 is sleeved on the outside of the bolt column of the slide bar 321 through the sliding hole set by itself, and is located between the front stopper 322 and the rear stopper 323. The fixing member 324 is sleeved on the outside of the bolt column of the sliding rod 321 through the sliding hole provided therein, and abuts against the bolt head of the sliding rod 321 on the side away from the sliding member 325. The bolt outer side of the sliding rod 321 is also threadedly connected with a nut for fastening the sliding member 325 to the bolt head of the sliding rod 321, so that the fixing member 324 is fixed to the sliding rod 321. The position where the fixing member 324 is fixed is not between the front limit member 322 and the rear limit member 323.

[0038] In this embodiment, the fixing member 324 is fixedly connected to the rear clamping unit 2 and the sliding member 325 is fixedly connected to the front clamping unit 2. Specifically, the fixing member 324 and the sliding member 325 have threaded rods on their lower sides, and corresponding threaded holes are provided on the clamping unit 2. The fixing member 324 and the sliding member 325 are both threadedly fixedly connected to the threaded holes of the corresponding clamping units 2 through their respective threaded rods. After such arrangement, when the sliding member 325 abuts against the rear limiter 323, the spacing between the front and rear clamping units 2 is the smallest. Correspondingly, when the sliding member 325 abuts against the front limiter 322, the spacing between the front and rear clamping units 2 is the largest. In other embodiments, it is also possible to consider fixing the fixing member 324 and the front clamping unit 2 and fixing the sliding member 325 and the rear clamping unit 2. This arrangement is consistent with the above-mentioned effect, and can constrain the maximum spacing and the minimum spacing between two adjacent clamping units 2.

[0039] In this embodiment, the driver 31 is specifically a hydraulic telescopic cylinder. In other embodiments, a gas cylinder, an electric cylinder or a screw mechanism may also be considered as the driver. The fixed end and the telescopic end of the hydraulic telescopic cylinder are both hinged with an articulated seat 311. In this embodiment, the articulated seat 311 of the fixed end is welded to the connecting plate 11 at the rear side, and the articulated seat 311 of the telescopic end is welded to the four clamping units 2 from the rear to the front. In this way, when the driver 31 is extended, it will drive the fourth clamping unit 2 to slide forward relative to the last clamping unit 2, and the fourth clamping unit 2 will drive the third spacing limiter 32 counted from the back to the front to slide forward. After the sliding member 325 of the third spacing limiter 32 abuts against the front limiter 322, the third spacing limiter 32 will drive the third clamping unit 2 to slide forward, and the transmission will be carried out in sequence. After the sliding member 325 of the first spacing limiter 32 abuts against the front limiter 322, the clamping units 2 arranged on the front and rear sides of the spacing limiter 32 are in the maximum spacing state. In this embodiment, the four clamping units 2 are all in the maximum spacing state, and the corresponding four columns of bricks clamped will also be in the maximum spacing state.

[0040] If it is necessary to reduce the spacing between the columns of bricks, the driver 31 can be controlled to contract to drive the fourth clamping unit 2 to slide backward. When the fourth clamping unit 2 slides backward, it will drive the third spacing limiter 32 fixed thereto to slide backward. After the sliding member 325 of the third spacing limiter 32 abuts against the rear limit member 323, it will push the third clamping unit 2 to slide backward. The transmission is carried out in sequence. After the sliding member 325 of the first spacing limiter 32 abuts against the rear limit member 323, the clamping units 2 arranged on the front and rear sides of the spacing limiter 32 are in the minimum spacing state. In this embodiment, the four clamping units 2 are all in the minimum spacing state, and the corresponding four columns of bricks clamped will also be in the minimum spacing state. In this way, the spacing of the clamped bricks can be changed by adjusting the spacing between each clamping unit 2, so that multiple columns of bricks with wider spacing can be clamped and stacked with a narrower spacing, or multiple columns of bricks with narrow spacing can be clamped and stacked with a wider spacing. This can adapt to a variety of stacking scenarios, so it can improve the transportation efficiency to a certain extent, which is conducive to market promotion and use.

[0041] It is worth mentioning that in this embodiment, the driver 31 is located between the two connecting rods 12, so that the clamping unit 2 directly driven by the driver 31 can be subjected to force in the center, so that the clamping unit 2 can move stably. In addition, each group of spacing limiters 32 in this embodiment has two spacing limiters 32, and the two spacing limiters 32 of each group of spacing limiters 32 are spaced and distributed on the left and right sides of the clamping unit 2, so that the pushing and pulling forces can be stably transmitted between the spacing limiters 32, so that each clamping unit 2 can move stably.

[0044] In this embodiment, the total number of clamping units 2 is 4, and the 4 clamping units 2 are arranged side by side on the slide 1. Specifically, among the 4 clamping units 2, the last clamping unit 2 (that is, one of the clamping units 2 of the first clamping module 2a) is fixedly connected to the slide 1 through bolts and nuts, and the two clamping units 2 of the first clamping module 2a are fixedly connected through bolts and nuts, and the remaining clamping units 2 are slidably connected to the two slide rails 13 of the slide 1 through their own two slide seats 21. It is worth mentioning that the clamping unit 2 of the first clamping module 2a also has a slide seat 21 assembled with the slide rail 13, so that the connection strength between the first clamping module 2a and the slide 1 can be improved.

[0045] In this embodiment, the spacing adjustment component 3 specifically includes a driver 31 and a spacing limiter 32. The number of spacing limiters 32 in this embodiment is 2 groups, and the 2 groups of spacing limiters 32 are arranged between the first clamping module 2a and the second clamping module 2b and between the second clamping module 2b and the second clamping module 2b to constrain the maximum spacing and minimum spacing between the clamping modules. Specifically in this embodiment, the 2 groups of spacing limiters 32 are arranged from back to front between the second clamping unit 2 and the third clamping unit 2 and between the third clamping unit 2 and the fourth clamping unit 2 to constrain the maximum spacing and minimum spacing between the above-mentioned clamping units 2.

[0046] With such arrangement, when adjusting the spacing, the four clamping units 2 can keep the spacing between the two rows of bricks on the rear side unchanged, and only adjust the spacing between the first three rows of bricks to meet various spacing adjustment requirements.

Specifically, the second clamping module 2b with one clamping unit 2 is located in front of the first clamping module 2a, and the first clamping module 2a with two clamping units 2 is at the frontmost side, and the two clamping units 2 of the first clamping module 2a are fixed to each other through bolts and nuts. It is worth mentioning that the clamping unit 2 of the first clamping module 2a also has a slide seat 21 assembled with the slide rail 13, so that the connection strength between the first clamping module 2a and the slide 1 can be improved.

[0050] In this embodiment, the spacing adjustment component 3 specifically includes a driver 31 and a spacing limiter 32. The number of spacing limiters 32 in this embodiment is 2 groups, and the 2 groups of spacing limiters 32 are arranged between the first clamping module 2a and the second clamping module 2b and between the second clamping module 2b and the second clamping module 2b to constrain the maximum spacing and minimum spacing between the clamping modules.
