As shown in fig. 1 and fig. 2, the present embodiment provides a washing machine framework carrying jig 100, and the washing machine framework carrying jig 100 can fix a washing machine framework 200 in multiple directions, thereby improving the fixing effect of the washing machine framework 200 and avoiding the phenomenon that the washing machine framework 200 falls off in the subsequent carrying process. The washing machine frame 200 is an important component of the washing machine, as shown in fig. 1, the washing machine frame 200 is formed by splicing a plurality of plates, two of the plates are arranged at intervals and fixed in relative positions to be used as to-be-clamped pieces 201, and a space allowing the washing machine frame carrying jig 100 to enter is formed between the two to-be-clamped pieces 201. It should be noted that the number of the to-be-clamped members 201 included in one washing machine frame 200 is not limited to two, and may be several times as many as two, and when the washing machine frame conveying jig 100 conveys the washing machine frame 200, one pair of the to-be-clamped members is selected to operate.
As shown in fig. 2, the washing machine frame carrying fixture 100 includes a driving assembly 110, two limit abutting plates 120 spaced along a first direction, and two clamping assemblies 130. The driving assembly 110 is in transmission connection with the two limiting abutting plates 120, and can drive the two limiting abutting plates 120 to approach each other or move away from each other. The two limiting abutting plates 120 can be arranged between the two to-be-clamped pieces 201, and the limiting abutting plates 120 can abut against the inner side wall surfaces of the to-be-clamped pieces 201 on the corresponding sides from the inner sides under the driving of the driving assembly 110. That is, the two limit abutment plates 120 can support the two limit abutment plates 120 from the inner sides of the two limit abutment plates 120 under the driving of the driving assembly 110, thereby achieving the preliminary fixing of the washing machine frame 200. The two clamping assemblies 130 are disposed on the two limiting abutting plates 120 in a one-to-one correspondence manner, and are used for clamping two to-be-clamped pieces 201 in a one-to-one correspondence manner along a second direction, wherein the second direction is perpendicular to the first direction. In this embodiment, the first direction is a horizontal direction, and the second direction is a vertical direction.
The process of fixing the washing machine frame 200 by the washing machine frame carrying jig 100 is as follows: first, the driving assembly 110 drives the two limit abutment plates 120 to approach each other in the first direction, so as to reduce the distance between the two limit abutment plates 120, and enable the two limit abutment plates 120 to be moved to between the two limit abutment plates 120; then, the driving assembly 110 drives the two limiting and abutting plates 120 to be away from each other in the first direction, so that the outer side wall surfaces of the limiting and abutting plates 120 abut against the inner side wall surfaces of the to-be-clamped pieces 201 on the corresponding sides, the two limiting and abutting plates 120 are supported from the inner sides of the space formed by the two to-be-clamped pieces 201 by the two limiting and abutting plates 120, and the initial fixing of the washing machine framework 200 in the first direction is further realized; finally, the corresponding to-be-clamped piece 201 is clamped from the second direction by the clamping assembly 130 arranged on the limiting abutting plate 120, so that the washing machine framework 200 is fixed again in the second direction.
Because first direction and second direction mutually perpendicular, compare in can only follow the fixed washing machine skeleton in a direction in current transport tool, the washing machine skeleton transport tool 100 that this embodiment provided can realize the fixed to washing machine skeleton 200 from two different directions, and stability is higher, has avoided the phenomenon appearance that follow-up washing machine skeleton 200 dropped because of the fixed poor stability. In addition, because the driving assembly 110 can drive the two limiting abutting plates 120 to approach or separate from each other in the first direction, the washing machine framework 200 with different specifications is suitable for being fixed, and the application range is wider.
Alternatively, in the present embodiment, the driving assembly 110 includes a rotary driving body 111, a bidirectional screw rod 112, a first nut block 113, and a second nut block 114. The bidirectional screw rod 112 is provided with a first thread structure and a second thread structure with opposite rotation directions. The first nut block 113 is threadedly coupled to the first threaded structure and forms a lead screw nut pair, and the second nut block 114 is threadedly coupled to the second threaded structure and forms a lead screw nut pair. The top end of one of the limit abutting plates 120 is connected to the first nut block 113, and the top end of the other limit abutting plate 120 is connected to the second nut block 114. The rotary driving body 111 is used for driving the bidirectional screw rod 112 to rotate, and optionally, the rotary driving body 111 is a servo motor. The driving assembly 110 can realize the mutual approaching or separating of the two limit abutting plates 120 by using one driving body, and has a compact structure and high moving precision.
Of course, in other embodiments, two motors and two screws with opposite thread turning directions may be provided according to requirements, and the two motors are used to respectively drive the two screws to rotate, so as to achieve mutual approaching or separating of the first nut block 113 and the second nut block 114, and further achieve mutual approaching or separating of the two limiting abutting plates 120. Of course, in addition to the above structure, the driving assembly 110 may further include two cylinders (two linear motors), and the two cylinders (two linear motors) are connected to the two limiting abutting plates 120 in a one-to-one correspondence manner, so as to directly drive the two limiting abutting plates 120.

As shown with continued reference to fig. 2, the clamping assembly 130 includes a linear driving body 131, a fixed clamping plate 132, and a movable clamping plate 133. The fixed clamping plate 132 is connected to the outer wall surface of the limit abutting plate 120, and in this embodiment, the fixed clamping plate 132 extends along the horizontal direction and is connected to the limit abutting plate 120 in a T shape.

It should be noted that, the initial position of the movable clamping plate 133 is far from the fixed clamping plate 132, and the distance between the two is greater than the height of the to-be-clamped member 201 in the second direction, so that the to-be-clamped member 201 of the washing machine frame 200 is located between the fixed clamping plate 132 and the movable clamping plate 133 after the initial fixing, at this time, the linear driving body 131 is used to drive the movable clamping plate 133 to move towards the direction close to the fixed clamping plate 132, and the to-be-clamped member 201 can be fixed in the second direction after the movement for a certain distance. In addition, it should be noted that the top of the member to be clamped 201 after the preliminary positioning is achieved may or may not abut against the lower bottom surface of the fixed clamping plate 132. If the clamping is not performed, after the movable clamping plate 133 moves to abut against the bottom end of the to-be-clamped member 201, the linear driving body 131 may continue to drive the movable clamping plate 133 and the to-be-clamped member 201 to move towards the fixed clamping plate 132 synchronously so as to lift the to-be-clamped member 201 upwards until the top of the to-be-clamped member 201 abuts against the lower bottom surface of the fixed clamping plate 132.

The arrangement of the vertical limiting plate 1332 can improve the fixing effect of the washing machine framework carrying jig 100 on the washing machine framework 200 in the first direction, and reduce the probability of shaking of the washing machine framework 200.
As shown in fig. 3, an avoiding structure 121 is provided on the limit abutting plate 120, a linear driving body 131 is connected to an inner side wall surface of the limit abutting plate 120, and a movable clamping plate 133 is provided through the avoiding structure 121.
