Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Embodiment one aims to promote the solution of the problem that the vibration of external environment or the impact inside the machine tool may cause the slight displacement of the workpiece or the tool during the machining process, thereby affecting the workpiece position precision, please refer to Figures 1-4A workpiece machining positioning device of a numerical control machine tool, comprising a machine tool body 110, a machining table 111 and an operation panel 112, the operation panel 112 is arranged on the machine tool body 110, a working groove 113 is arranged in the machine tool body 110, the machining table 111 is arranged in the working groove 113, a supporting plate 114 is arranged at the bottom of the machining table 111, a supporting rod 115 is arranged at the bottom of the supporting plate 114, a machining head 116 is arranged in the working groove 113, the machining head 116 is located on the upper side of the machining table 111, a sliding groove 117 is arranged on the supporting plate 114 and the machining table 111, a control rod 118 is inserted into the sliding groove 117, a clamping plate 119 is arranged at the end of the control rod 118, a cavity 120 is arranged in the supporting plate 114, and a driving assembly 121 for driving the control rod 118 is arranged in the cavity 120. The control rod 118 and the clamping plate 119 are arranged in two groups, and the two groups of control rods 118 and clamping plates 119 are symmetrically arranged.

[0023] The driving assembly 121 comprises a first rack 122 and a second rack 123 arranged in the cavity 120, a gear 124 is arranged between the first rack 122 and the second rack 123, the first rack 122, the second rack 123 and the gear 124 are meshed, a driving rod 125 is arranged at the bottom of the first rack 122, a driving cylinder 126 is arranged at the bottom of the supporting plate 114, and the output end of the driving cylinder 126 is fixedly connected with the bottom end of the driving rod 125. The first rack 122 is fixedly connected with the bottom end of one control rod 118, and the second rack 123 is fixedly connected with the bottom end of the other control rod 118. The workpiece to be machined is placed on the machining table 111.

[0024] The driving cylinder 126 is started by operating the operation panel 112, and the output end of the driving cylinder 126 pulls the driving rod 125 to move to the right. The driving rod 125 drives the first rack 122 to move to the right in the cavity 120, and since the gear 124 is meshed with the first rack 122, the gear 124 will rotate. The rotation of the gear 124 further drives the second rack 123 to move to the left in the cavity 120, because the first rack 122 and the second rack 123 are connected through the gear 124. The movement of the first rack 122 and the second rack 123 respectively pushes the two groups of control rods 118 and clamping plates 119 to slide in the sliding groove 117 to the machined workpiece.

[0025] When the two groups of clamping plates 119 move to the appropriate position, they tightly clamp the workpiece on the machining table 111, ensuring the stability and position accuracy of the workpiece during machining. After the workpiece is stably clamped, the machining head 116 is controlled to perform cutting or other machining operations through the operation panel 112. Since the workpiece is firmly clamped, the influence of external environmental vibration or machine tool internal impact on the position accuracy of the workpiece will be significantly reduced.

[0026] After the processing is completed, the driving cylinder 126 is controlled to move reversely through the operation panel 112, so that the clamping plate 119 releases the workpiece.

[0027] The processed workpiece is taken out for subsequent processing or detection.

[0028] In this embodiment: through the two groups of symmetrically arranged control rods 118 and clamping plates 119, it is ensured that the workpiece is uniformly clamped during processing, and the workpiece deflection or deformation caused by a single clamping point is avoided. Through the precise control of the driving assembly 121, the driving assembly 121 cooperates with the rack, gear 124 and driving cylinder 126 to accurately control the position and clamping force of the clamping plate 119, so that the workpiece remains stable during processing. The bottom of the processing table 111 is provided with a support plate 114 and a support rod 115, which provides a solid support structure and effectively reduces the influence of vibration and impact generated during the operation of the machine tool on the workpiece.

[0029] Embodiment two, this embodiment aims to promote the solution of positioning error problem caused by gap or misplacement of parts, this embodiment is an improvement based on embodiment one, for details, please refer to Figures 1-4 . The limit rod 130 is installed in the cavity 120 and rotatably inserted into the gear 124. The first rack 122 and the second rack 123 are symmetrically arranged with the gear 124 as the center.

[0030] The bottom of the support plate 114 is provided with a sliding groove 131, which is communicated with the cavity 120, and the driving rod 125 is slidably inserted into the sliding groove 131. The sliding groove 131 opened at the bottom of the support plate 114 is communicated with the cavity 120, allowing the driving rod 125 to freely slide in the sliding groove 131, thereby reducing the frictional resistance when the driving rod 125 moves, ensuring smoother transmission, and further improving the clamping speed and accuracy of the clamping plate 119.

[0031] The clamping plate 119 is provided with a bonding strip 132 on the surface, and the bonding strip 132 is made of high-temperature-resistant rubber strip. The bonding strip 132 installed on the surface of the clamping plate 119 is made of high-temperature-resistant rubber strip, which can withstand high temperature during processing, preventing material deformation and performance degradation caused by processing heat. This improvement effectively protects the workpiece and prevents the clamping effect from decreasing and the position from deviating due to temperature change during processing.

[0032] The working groove 113 is hinged with a protective door 133, and the protective door 133 is provided with an observation window 134, which is made of transparent glass window. The protective door 133 hinged on the working groove 113 can effectively block the metal chips and cooling liquid splashed during cutting without affecting the operation, thereby increasing the safety of the operator.

[0033] In the embodiment, the rotation range of the gear 124 is limited by installing the limiting rod 130 in the cavity 120, so that the rotation accuracy of the gear 124 can be improved, the synchronous movement of the first rack 122 and the second rack 123 is more stable, the positioning error caused by the gap or misalignment between parts is reduced, and the machining accuracy of the workpiece is improved.
